  • Automation Testing Tutorial: A Comprehensive Guide With Examples and Best Practices


Do you know? The word “Automation” was first coined in 1946, originating from the automobile industry. It was used to specify the increasing usage of automatic controls and devices in mechanical production lines. Behold! It wasn’t only in the automobile industry, but automation has found an application in almost every part of our day-to-day life in just a short span of 76 years (Mind it, the earth is reportedly 4.543 billion years).

The good news for testers and developers is the privilege of automating their tests on a growing basis.

If you are wondering what is automation testing, it’s a software testing technique through which you can automate your test execution using automation testing tools. However, the decision to implement automation testing from scratch should be based on the current issues you face while testing your application and not merely because your team or you were fascinated by the word automation. Taking the right decision at the right time is more important for better quality achievement and ROI.

In this automation testing tutorial, we will take a detailed look at what is automation testing, why to choose automation testing, and much more.

What is automation testing?

Automation testing is widely known as the process where you test a specific application to check if it meets the needed requirements and expectations using an automated testing tool. We perform automated testing to cross-check if the software application can perform the same way we expect it to perform. Even though you can understand the software testing life cycle (STLC) and do a few tests manually, whether functional testing or regression testing, benefits abound when you want to do it automatically.

Even though times are changing, many automation developers are still holding close to programming languages such as C#, Ruby and JavaScript. Who spends their working hours sorting out bugs? That’s where Quality Assurance (QA) automation testers come into play. Their job is to design and write their test scripts at the beginning. The job of a QA automation tester would be to collaborate with product developers and automation test engineers to test their products and software.

Automation testing is important because it helps ensure the correct functionality of the software application in a timely manner and without needing extensive human involvement. It bridges the gap between developer and tester by providing a platform where tests can be designed and executed without waiting for manual assistance from a tester or developer. A tool like Selenium allows developers and testers to create tests using their coding language

It could be on the basis of the debate between code-based vs codeless test automation, and picking either codebased or codeless automated testing. They would act with a team spirit and take control over the test automation tasks with the aid of automation testing frameworks for successful test automation.

Why do you need automation testing?

This section of automation testing tutorial emphasize the importance of test automation.

Every test engineer, from a junior tester to a test lead, would focus on catching hold of them before product release, even with the best manual testing processes and team strength. What do we do to get rid of them? That’s where test automation comes into play. We can utilize it to one-up the efficiency, effectiveness, and test coverage.

We perform manual testing with human support while comparing what results we have achieved so far with what we expected. Repeating manual tests during development cycles for changes in the source code is a norm. In such cases, it’s advisable to automate repeated test cases to save time and money.

When we talk about manual testing vs automation testing, many teams struggle when they have to manage their budget and resources to test the software manually. With automation testing, you can reduce the time you take to test your software product since it runs efficiently and quickly. This hands over the time capsule to the product managers and developers, who can fast-track their efforts into different project aspects. This would lead to a productivity increase.

It’s important to know that automation can make product development seamless since designing and producing a website, web app, or mobile app can become hassle-free. Moreover, the business can work hand-in-hand on different products and software without increasing its team strength. This gives way to perfecting the final software products and, after that, introducing new products into the market.

If you have just started with automation testing or have moved from manual to automated testing, this automation testing tutorial on how to move from manual testing to automation will help you kickstart your test automation journey.

What are the benefits of automation testing?

When you use automation technology, it translates to the importance and dominance of testing frequently. With software development and testing life cycle, you might need to test the same regularly. This is where automation testing removes the barriers without distracting the team members from concentrating on the work. While automation takes care of this for you, you can ensure that the product is market-ready by moving forward to the next development stage. This kind of validation supported by automation testing makes team members feel great about their work.

Let’s go deeper in this automation testing tutorial to explore the benefits of automation testing.

Save more time and money

In the world of business, time translates directly to money. Since many tests require repetition during development cycles when the source code gets modified, automation testing is inevitable when you want to save cost and time. You might also have to ensure cross browser testing to check if the product works well on different browsers, OS, and hardware configurations. It’s nearly impossible to perform them manually, given many constraints such as geographical location and budget, especially for startups. In that case, you can use the best online cross browser testing tool for startups, such as LambdaTest, to get the most productive results.

Increase your test coverage

Automated software testing can skyrocket the scope and depth of each test when they want to improve software quality by getting better at software testing. You can forgo the hurdles you face when you run lengthy software tests usually avoided during manual testing. While getting rid of the challenges faced during automated website testing and mobile app testing, you can delve deeper into the performance of an application and explore data tables, memory contents, internal programs, and file contents to understand if the product's behavior is as per the expectation.

With test automation, you can also perform parallel testing while executing many complex test cases with unmatchable code coverage and test coverage at every test run.

Automation can substitute Manual Testing in many places

To err is human. A proficient tester is also bound to commit mistakes during monotonous manual testing. Automated tests make it simple to perform and repeat the same steps concisely every time. You can also record the results in a detailed manner.

Automated Testing is the best friend of testers and developers

You can use shared automated tests much quickly before they reach the hands of QA. Tests can run automatically whenever source code changes are checked in and notify the team or the developer if they fail. Features like these save developers time and increase their confidence.

Boosts the morale of the Dev and QA Teams

At LambdaTest, our testers are always in favor of automation testing since automated testing offers your team members more time to focus on the most challenging projects. This would lead team members to increase their confidence and skill set. For instance, when you automate accessibility testing, you open doors for a large audience to your software product, irrespective of disabilities. This will lead to work satisfaction.

In the next section on automation testing tutorial, we will see how organization use automation testing in their workflow.

How can organizations utilize automation testing?

Since many organizations have moved on to Agile and DevOps methodologies for software project delivery, people have started demanding high-end efficiency and speed. Hence automation testing has become inevitable for modern organizations. As per GMInsights, the global test market will have increased by $40 billion in 2020. The overall growth would be between 7%-12% CAGR until the end of 2025.

A study by NASSCOM in 2020 states that nearly 25% of their respondents have gone on to automate 51% to 75% of testing processes. This shows the value of automation testing for businesses. Many of our clients have asked us, “What is the automation testing benefit I can reap?”. Automation testing is sure to increase your business ROI. Let’s prove this with our real-life Trepp case study in this automation testing tutorial.

Trepp, a subsidiary of Daily Mail and General Trust (DMGT), is a British media company that caters to insurance risk, consumer media, education technology, property information, and events & exhibitions.

When Anish Ohri, Head of Testing and Performance Engineering at Trepp, approached us, he looked forward to expanding the team’s delivery capability and quality at speed. Their bucket list included faster delivery with the jet-speed test cycles, increased test automation coverage, and multi-browser testing. Anish strongly believed in the power of the shift left testing approachto test and provide faster test feedback. With digital transformation, Trepp leveraged many web browser versions, operating systems, and environments.

But this didn’t involve cross browser automation testing. Since frequent upgrades, changes, and features were added to the system, it paved the way for shorter sprints. This became extremely challenging when they wanted to ensure that the Trepp CMBS web application UI would work as expected on different browsers, OS, and hardware configurations.

Anish wanted to automate the entire QA workflow and bring cross browser automation for future plans. The team was skeptical when they looked at the benefits of hiring an in-house grid over cloud platforms. The challenges included the high cost of building an in-house device lab instead of an online device farm, huge time spent, in-demand issues in scalability, the need for a dedicated DevOps team for maintaining the device lab, and the inability to run parallel test sessions at scale.

Their final decision was obvious! Anish picked up our cloud ecosystem for the most comprehensive end-to-end cross browser automation testing as a part of their process.

What benefits did the Trepp team achieve by opting for LambdaTest automation testing?

The QA team worked on the unit testing framework, integration testing, and End to End testing in parallel while executing scripts in parallel on the LambdaTest cloud platform. This brought down the test execution time.

  • Tests that take 2-3 days for a single round took only a couple of hours.
  • They were able to run a number of test cycles in a sprint.
  • They got their hands on GitHub Action and Package registry to automate CI/CD process through integration with CI/CD tools.
  • They could now run Selenium test automation scripts on a modular and extensible online Selenium Grid. Since their SDETs were Java experts, they used the TestNG framework and JUnit framework to perform unit testing and depended upon Rest-Assured to perform API testing.
  • Increase test coverage on different browsers, OS, and hardware device configurations.
  • Get faster details and reports on visual bugs.
  • Assure the best UX on legacy configurations.
  • Get better-integrated insights via automation analytics and logs.
  • Reduce the time and cost needed to maintain infrastructure or test the farm.

What’s the good news?

The team happily reported that they could improve their productivity by 2x and browser coverage by 40x.

Here is their feedback:

“As LambdaTest’s Selenium Grid was compatible with every test automation framework and language which Selenium supports, the transition was quick and smooth, and my team can now run Selenium automation using various Java frameworks. Running our Selenium scripts on the legacy and latest browsers on LambdaTest helped us save significant time in test execution with zero hassle in maintaining the infra. It was quick and easy to get started with the LambdaTest platform, and thanks for their 24/7 support availability.”

We have demonstrated this case study to show how cloud-based automation testing can simplify your professional life by saving time and cost.

Which tests should be automated, and which shouldn’t be automated?

This section on automation testing tutorial focus on what test cases to automate and what to not. Let’s explore it in two parts: what is automation testing (automatable) and what is automation testing (non-automatable). Even though you can automate tests such as smoke tests, sanity tests, and regression tests, tests that require human expertise might need manual intervention. Here is a table demonstrating the same.

Automatable testsNon-automatable tests
Tests need to be run against every application build/release, such as regression tests.Tests you need to run only once in a lifetime
Tests making use of the same workflow, but different input data for every test, like boundary tests and data-driven testsUser experience tests involving human opinion
Tests requiring you to collect multiple info during runtimes, such as low-level application attributes and SQL queriesTests that are short and needs to be done soon, where writing test script would consume extra time
Tests that can be used for performance testing, like stress and load testsTests in need of ad hoc or random testing based on domain expertise or knowledge.
Tests take a long time to perform; you may have to run them apart from your working hours or on breaksTests with unpredictable results. If you want automation validation to be a success, the results should be predictable
Tests where you input large data volumesTests where you need to watch to ensure that the results are right constantly.
Tests that need to run against multiple configurations — different OS & Browser combinations, for example.Tests that don't need to be performed against multiple browsers, OS, and devices.
Tests during which images must be captured to prove that the application behaved as expected (Example: Screenshot testing)Simple tests with no added value to your team.
Automatable tests that carry utmost importance to your product.Tests that don't focus on the risk areas of your application.

What are the types of automation testing?

In this part of our automation testing tutorial, we will explore the types of automation testing. Types of automation testing are more or less similar to types of manual testing, but how we approach and carry it out makes a lot of difference. There are two types of testing:

  • Functional testing: This type of testing would test the business application on a real-world basis. For example, a food delivery app such as Uber eats should be able to team up with its delivery partners to hand over food ordered by restaurants once they order through the app. This is an example of functional testing.
  • Non-functional: This type of testing answers if the software requirements are met, be it security, performance, and data storage. Considering the food sharing example, it would ensure that the app performs quickly, securely, and efficiently when a user carries out the payment through online payment methods.

Type of Automation tests

Are you curious to know more about automation testing common types? This section on automation testing tutorial focus on commonly used types of automation testing:

  • Smoke Testing: This type of functional testing covers only the needed features of any software solution. Smoke testing aims to verify that the build is in a releasable state and to detect major regressions in the code.
  • Integration Testing: This test would piece out every functionality and individual code piece of any software solution while testing them as an integrated entity to ensure smooth software operation.
  • Regression Testing: They are a combo of both Functional and Non-functional tests where you check if the software or app has “regressed” or changed after you make a code change.
  • Security Testing: This type of testing is a part of both functional and non-functional where you test your software for a particular vulnerability. It could show weaknesses as well as any vulnerabilities.
  • Performance Testing: Non-functional tests would help every tester evaluate criteria such as stability and responsiveness since the software would handle more stress and load.
  • Acceptance Testing: This is a kind of functional test to check for a software's acceptability factor to its end-users. Acceptance testing is the final test that is a must to crack for any software before it goes through beta testing and eventually gets live to the general audience.

Important Phases of automation testing

Test automation is a complex process, and many phases lead to the successful automation of a software application. Automation testing is executing a previously defined test case suite against a software application to validate that the software meets its functional requirements.

During the automation testing phase of the Software Development Life Cycle (SDLC), an organization or a project team identifies and defines test cases that can be automated and then creates automated scripts to perform these test cases. This section on automation testing tutorial discuss the following are important phases of automation testing:

  • Test Requirement Planning: It is important to understand what exactly you are testing and how it needs to be tested. Test requirement planning is the first step in achieving automated testing goals. We will decide on what needs to be tested along with the testing strategy. This phase involves defining test cases, identifying test scripts, and deciding who will execute them.
  • Test Execution: This phase executes the planned tests to simplify the future execution of tests. The output of this phase is reports, logs, etc.
  • Test Reporting: After executing the planned tests, there should be a ready report for us to judge if test cases pass or fail. This phase involves tasks like analyzing logs and getting results from automation tools.
  • Test Maintenance: This phase includes tasks aiming to improve existing software applications by fixing bugs or adding new features. Once all these tasks are done, we can call our application a robust and fully functional one.

Types of automation testing frameworks

Once the types of automated testing used in a project have been determined, an automation test framework is chosen to help testers organize and standardize the process. The benefits of standardization are evident in many ways.

Having an overarching structure and guidelines makes projects more accessible to newcomers, which helps teams scale, especially bigger teams where there are potentially tens to hundreds of individual approaches to automated testing. If all of them were implemented haphazardly without any form of control, it would be disastrous for the product's quality and the team's success.

Wondering what the automation testing framework type is? Even though you have plenty of automation testing frameworks in the market, they can be broadly classified into these three types:

  • Linear Framework (or Record and Playback): This framework is known to be the most fundamental type of framework. Over here, testers would write and run their test script for individual test cases, such as recording and playing back a clip on a particular screen. This is what led to the name “record and playback.” Due to its simplicity, it’s widely used by bigger teams and test automation beginners. Know the difference between scripting testing and record & replay testing.
  • Modular Based Framework: Suitable to its name, we use this framework to organize each test case into tiny parts known as modules, where the modules are quite independent. We handle the modules of any provided scenario uniformly by using a “master script,”

    This would save a lot of time for the testers, where you can also optimize the workflow. But you would need prior planning, as well as expertise in test automation, is needed to implement this testing framework.

  • Library Architecture Framework: This is built with a Modular framework as the base. The Library architecture framework would let you break up the test case while similarly grouping tasks within the test script into different functions while storing them in a library.

    These functions would hold tasks with particular objectives. The test script can call them upon when it needs functionality. This framework enhances reusability and flexibility but demands more time and expertise.

  • Data Driven Framework: A Data-driven testing framework is one in which test cases are written around a dataset rather than a set of steps. This can be useful if a project is under time pressure or if the number of test cases is enormous.

    With this framework, the test cases can be executed by anyone with access to the data, as long as they can import it into their testing platform. The typical data-driven testing framework will include a suite of test steps, with each step containing all the information needed to execute that step against a dataset.

  • Keyword Driven Framework: A Keyword driven framework is a software design pattern in which the implementation of a system is separated from its specification and implementation. The specification is expressed as an interface that contains method names without any associated implementation.

    The implementation of the specification is expressed as an interface stub (or proxy) that contains method implementations but does not expose the code that implements the methods. The code that uses the interfaces to access data and services does not depend on a particular implementation, so it can be changed later if needed.

  • Hybrid Testing Framework: Hybrid testing framework is a test automation framework that combines manual and automated tests to achieve higher-quality software. The Hybrid Testing Framework builds upon the foundation of Behavior-Driven Development (BDD), Test-Driven Development (TDD), and Acceptance Test-Driven Development (ATDD). Rather than focusing on a single approach, Hybrid Testing Framework utilizes BDD's human-readable feature files, TDD's unit tests, and ATDD's acceptance tests.

The next section of this automation testing tutorial talks about scope of automated testing.

Scope of automation testing

What is the automation testing scope? To answer this question, you need to find an answer to “how much do you automate your test?” This question is essential when you want to determine the automated testing scope. Automation testing would facilitate configuration, security, and load tests when you involve system tests. Regression testing would go hand-in-hand with automation when you develop the product and at the early stage of product release.

Processes such as planning, test design, test builds, test execution, test analysis, test verification, validation, and test reporting phases, including software and system configuration, defect tracking, and software metrics, would all come in unison to upgrade test management strategies. Depending on how you manage the testing process, the automation process would vary.

The QA testing team would be the backbone of any testing project. The efficiency and scope of the testing team depend upon how much the testing team would adhere to these testing practices:

  • Risk analysis – Mitigate risk when you run test procedures that are vital to your enterprise.
  • Functional specifications – Allow parallel testing to check for the functionality of an app or a website.
  • Inspections and reviews – Efficiently expand the scope of debugging software.
  • Cross platform testing – Involve cross platform testing for code modification and to manage performance on various server platforms.
  • Beta testing – Release the product to a limited number of users and customers through beta testing.
  • Automated test execution – Evaluate the results with the help of automated test management.

How to select the right automation testing tools?

You need to set standards on what is an automation testing tool requirement. It’s always a challenge when you want to choose the right automation testing tool to run your business. When you aren’t fully aware of the advantages and disadvantages, chances are high that it could backfire your entire test cycle. Ensure that you consider what your business requirements are. Then you need to analyze them thoroughly before making the final decision.

Before you analyze the needed result, you shouldn’t fail to look at all the key criteria it would go on to satisfy. Leveraging the Pugh Matrix technique could also help you out when you want to determine the top criterion.

Experts also advise using your current testing tool as a benchmark. Then you can watch out for newly introduced automation testing tools in the market to look at the best and worst-case scenarios.

Getting Started with automation testing

When it comes to automation testing, Selenium offers a solution for performing cross browser testing. This is especially useful if you have a large application that requires testing in multiple browsers. The local Selenium Grid allows you to perform automated WebDriver tests in remote browsers that helps testers automate browser based functional tests, which allows thorough and deep testing of the application from its UI layer.

However, a more scalable option is to use the remote Selenium WebDriver to perform browser compatibility testing on multiple combinations of web browsers, devices, and operating systems.

In the next section on automation testing tutorial, we will explore how to perform automated testing on local and cloud Selenium Grid.

Local automated browser testing

Using the local Selenium Grid is a simple way to satisfy your testing needs. With the local Selenium Grid, you can run tests against different versions of browsers and operating systems without the hassle of setting up multiple virtual machines.

To get started with test automation using Selenium on your local machine, you need to download and install the appropriate browser driver for the browser on which you plan to perform the test.

For more information in this automation testing tutorial on Selenium WebDriver, see earlier articles that delve into its architecture and other important aspects related to its use for automation.

Automated browser testing using remote Selenium Grid

Locally running automated browser tests works fine, if you're only concerned with a few browsers. However, when you have to test your site with many different browser combinations, the situation changes.

In cases like these, in-house Selenium Grid can’t be used. Instead, the organizations should go with a cloud-based cross browser testing platform like LambdaTest. On a cloud-based platform like LambdaTest, Selenium tests can leverage the grid’s capabilities to execute tests against multiple combinations. Such tests will help in achieving great test coverage and parallel execution, thus providing more confidence in their product.

To get started, you need to create a LambdaTest account. Once the account is created, make a note of your username & access key in the LambdaTest Profile Section. The LambdaTest Dashboard will help you with necessary information about the tests, logs and will demonstrate the status of the tests running as well as allow you to view video recordings of your previous tests. You can make use of the LambdaTest Capabilities Generator to generate the capabilities for the browser on the platform on which you need to perform cross browser testing.

Limitations of automation testing

Do you know what the automation testing boundary is? Before exploring the software automation limitations, you should know that the quality of your QA testing is directly proportional to the test automation strategy you have laid upon. If you ignore the automation testing limits, it could add up to the bottlenecks of QA.

Don’t forget these automation testing cons, which can pop up if your testing strategy isn’t as strong as it should be. This section of the automation testing tutorial covers the limitations of test automation.

  • Tests constrain themselves to only what they have been programmed to do.
  • Developing a quality test case takes time. Hence early-stage time consumption can be high for automation testing.
  • The initial cost of a subscription to an automated cloud testing platform can seem expensive, even though it’s worth your spending in the long run.
  • The tests may lack a human touch of creativity in areas such as UI testing.
  • Continuous testing means continous code maintenance. If you fail to do this, it leads to flaky tests.
  • Although you can perform exploratory tests, you cannot automate usability testing since it requires human intervention to a certain extent. In such scenarios, you can go for real-time and real device testing of your website or app.

Best practices for automation testing

Automation testing has gotten the attention of testing teams across the globe. Many businesses have recently switched to the automated browser and visual regression testing. In this section of automation testing tutorial, we will discuss best practices for automation testing to get the most out of it.

Decide the test cases which might require automation

It’s not possible to automate every test. You need to check what automation testing requirements are before you decide to automate. Hence you need to sit with your team and prioritize the test cases you need to automate. First, you need to set a goal and determine the tests you need to automate. Each type of testing is unique.

It’s strongly suggested to check the app functionality as soon as you add it. You can also take some time to organize your smaller tests into larger automation tests. Organizing automated tests based on the functionality and major or minor application division is also recommended. When an automation test would refer to a different test, you would need to create a test tree to run tests in a particular order.

Choose the best automated testing tool

Which automation testing tool do you need to learn about? This is an answer everyone needs to know, right from beginners who are starting to seek an answer to the question “What is automation testing?” to experts in the testing domain. Even though there are plenty of automation testing tools in the market, the tool you choose should be good enough to simplify your automation testing tasks and give you a break you need.

For example, at LambdaTest, we have made automation testing seamless for you through our easy on-boarding process.

LambdaTest is a cloud-based cross browser testing platform where you can fasten your release speed with high-end test automation on the cloud.

Here is a detailed video on automation testing and how to perform automation testing using LambdaTest.

Allocate testing tasks wisely

Know your team strength before allocating the tasks. For example, a few team members might be stronger when they write automated test scripts. A few of them might do well when asked to write test cases. Some may excel at writing test reports. Hence it’s always good to know what your team is good at. To ensure that this happens, team communication is a must. When automation testing tools possess integration with project management tools such as JIRA integration and Slack integration, they will help you out, in the long run, to keep your team communication smoother.

High-quality Test Data is mandatory

Test data is mandatory for data driven framework testing. The input data is usually stored as a part of an external file. You can read the data from a database or other sources such as database tables, Excel sheets, XML, or text files. The best automation testing tool is the one that gets a clear gist of the data file content and iterates the content in the automation test. Automation tests become reusable and easy to maintain when you leverage external data.


Hope you have got an overview on what is automation testing, why you need it and how to make the most out of it. Automation testing is indeed changing the way businesses carry out testing in the recent days.

Happy Testing!
