Agile is an iterative development technique where testing and development are done simultaneously. Before we understand the Agile testing requirements, let us first try and understand the fundamentals and key details related to Agile.
Agile is the ability to create and respond to changing requirements. It is a way where you deal with uncertainties and eventually succeeding it. It is based on the Agile Manifesto, where you adapt to changes, identify the issues, and then figure out how you can adjust as you go along.
In this tutorial on Agile testing, let’s dive deep into the history of Agile testing, its advantages, disadvantages, methods, quadrants, and best practices.
This WebDriver tutorial explores what WebDriver is, its features, how it works, best practices, and more.
Let’s Dive in!
The late 1970s saw a shift in technology with the introduction of personal computing. This meant that you had to meet customer requirements that were changing rapidly. You cannot rely on the traditional software development approach like Software Development Life Cycle (SDLC) for your software solutions and delivery.
By the early 1990s, a small group of software industry leaders had started developing and promoting new approaches that helped them to tackle changing requirements. In 2001, a small group of industry leaders met to introduce new and advanced methodologies. It was when the term Agile software development was first used. The set of values for using Agile, known as the Agile Manifesto, came into existence.
Agile Software Development is way beyond frameworks such as Scrum, Extreme Programming, or Feature Driven Development (FDD). It is an approach or mindset where you approach the software development process in a structured manner. It is driven by values and principles where you deliver iterative and high value to your customers.
One thing that separates Agile from other approaches we use in software development is the focus on individuals doing the work and how they work together to deliver significant value. The self-organizing cross-functional teams work in close collaboration, which is excellent from a customer delivery perspective.
Core values of Agile software development include:
Let us understand Agile testing since we are aware of the basics related to the Agile software development approach.
It is a testing practice that works on the rules and principles of Agile software development. Unlike the Waterfall method, Agile testing begins right at the beginning of the project, with development and testing happening simultaneously. It is a continuous approach where the development and testing teams collaborate closely to get things done. The objective of Agile development and testing is to achieve high product quality.
If you have been using the Waterfall model and planning to shift to Agile methodology, read through this tutorial on moving from Waterfall to Agile testing .
Agile Development is a set of principles and practices for delivering high-quality software in a rapid, incremental, flexible, and cost-effective manner. Agile values software development's "people" aspects, including individuals and interactions over processes and tools. It embraces change to meet customer needs with rapid adaptation to market conditions and technological advancements.
Here are some key concepts used in Agile and Agile testing:
Below are the major differences between Agile testing and Waterfall testing:.
|Agile Testing||Waterfall Testing|
|It is an unstructured approach compared to waterfall testing, where you are not doing detailed planning.||The testing process is more structured, and a detailed analysis is done during the testing phase.|
|Since the testing begins at the start of the project, you can identify and fix issues when needed. This means you are well equipped to handle issues encountered during the project delivery.||The product is tested once the development is completed. For any issues, you need to go back and fix those issues. So, a lot of time is invested in performing testing and validation of those issues.|
|There is less documentation required for Agile testing.||The testing in the Waterfall approach requires detailed and elaborate documentation.|
|The features are shipped to the customer at the end of every iteration.||The features developed are delivered in one go once the implementation phase is completed.|
|Testers and Developers work in collaboration.||There is not much collaboration between developers and testers.|
|User acceptance is performed at the end of every sprint.||User acceptance can only be performed at the end of the project.|
|The testing team needs to be proactive and establish good communication with developers so that requirements can be analyzed and planned accordingly. The testing team needs to provide exact testing estimates in each sprint.||Testers can provide effort estimates once the development is over.|
Because Agile projects are often used with early release and often release methodologies, the need for an efficient testing process is crucial. In traditional projects, the testing process is often overlooked. Agile's focus on quality allows the team to identify defects early on while they are still easy to fix.
Early detection means that the developers can fix issues before they become costly and time-consuming issues. With a traditional approach, it might be too late when the customer discovers a defect because the defect might have been released to production.
Further advantages of Agile testing include:
Here are some of the shortcomings you must be aware of:
The kind of tests performed in each iteration is included in the Agile test plan. This consists of the test data needs, architecture, test environments, and different test results. The test plan is updated in every sprint. The Agile test plan contains the following aspects:
Agile testing life cycle contains five main phases:
Let us discuss each of these phases in detail:
Phase 1: Impact Assessment
The first phase of the Agile testing life cycle is Impact Assessment. The required inputs and feedback are collected from users and required stakeholders to execute the impact assessment phase. This allows the testing team to decide on the expectations and needs for the next life cycle.
Phase 2: Agile Testing Plan
The second phase of Agile testing is Agile test planning. In this phase, all the required stakeholders such as developers, testers, business analysts, end-users, and even customers meet and finalize the testing process strategies, schedules, and deliverables.
Phase 3: Release Readiness
The third phase of Agile testing is Release Readiness, where the validation of features and enhancements are done by the testing team. The test engineers review and test the features to make sure that they are good enough to go live or not. Some of the features that are not built right need to be sent back to the development team.
Phase 4: Daily Scrums
The fourth phase of Agile testing is Daily Scrums. This is the daily status update meeting that helps to track the testing activities daily. It also allows an opportunity to discuss potential issues or blockers impacting product delivery. You can raise your problems or concerns repeatedly to provide a quick resolution.
Phase 5: Test Agility Review
The final phase of Agile testing is the Test Agility Review. It is about reviewing the key goals and milestones from a development perspective. It is all about reviewing some key aspects to ensure the project's progress is on the right track.
The Agile testing process is driven by some key principles:
The following methods are supported in Agile testing:
There are so many types of tests, such as acceptance testing, regression testing, unit testing, and more. There are also scenarios where we need to decide whether manual or automated testing is better suited for the existing project or not. Gregory and Crispin introduced the concept of Agile testing Quadrants, which help you to decide the tests that need to be performed.
It is divided into four main quadrants:
Q1 - The Automated quadrant contains tests that are designed to improve the code quality of the product and helps the team to create better outcomes.
Q2 - The Automated and Manual quadrant contains tests that help to improve the business outcomes related to your product.
Q3 - The Manual quadrant contains tests with timely feedback for tests in quadrants 1 and 2. The required business outcomes can be achieved using comprehensive testing of the product.
Q4 - The Tools quadrant contains tests to ensure that technology can help the code fulfill required non-functional requirements such as security, scalability, etc.
It is important to understand how teams can perform Agile testing so that they can derive maximum business value. Some of the key aspects include:
Having the right strategy in place for Agile testing within your teams is important. The testing team should be well aware of the testing scope and schedule so that they can plan their testing accordingly. When done right, Agile testing can greatly impact the overall end-user experience.
Agile testing has become an integral part of the application lifecycle and gained widespread acceptance for delivering high-quality products. This means that the different teams must work in close collaboration to achieve desired outcomes. This is where you need the expertise of a unified cross browser testing platform to make sure that the Agile testing requirements are implemented in real quick time.
Cross browser testing ensures that your web application works seamlessly across different supported browsers without impacting the overall quality. This is why LambdaTest has transformed the entire testing ecosystem with a unique set of features and enhancements.

Agile testing can be challenging if not performed considering some of the Agile testing best practices.
Agile development is not just about programming, it extends to all aspects of the software life cycle. As a result, Agile testing best practices vary from other testing methods in some fundamental ways.
Each phase has its purpose and time frame, and it is up to the organization to decide which activities fall within which phase. A new Agile tester needs to be aware of these phases and activities and knows how they impact the overall testing process.
Follow the following best practices to avoid Agile testing challenges:
Agile software development relies on many principles and techniques to produce high-quality software. One of the most important is code austerity, which means keeping your code clean and simple by pruning away unnecessary elements.
As you create your test cases, you'll inevitably find that some tests must be repeated for each new feature or bug fix. The same test case might need to be run for every build type, branch, and environment. A test case with many variations is a sign of bad design.
Agile has made testing more critical than ever. With frequent deployments, ensuring that your software is always in a deployable state and working as expected is important. This requires well-tested and maintained code. To achieve this, Agile teams must make sure they have clear communication between their testers and developers.
Communication is essential in Agile because the team constantly adjusts its sprint priorities based on changing requirements. Both testers and developers must be able to adapt to these changes quickly, so they must always be in sync about what each team member is working on at any given time.
When you test one functionality at a time, it is easier to figure out what went wrong and why something did not go according to your expectations. If you have already tested a certain functionality, then you know that this particular feature works fine, and there is no need to spend time on it again.
We discussed different aspects related to Agile testing in this blog. Agile testing is an iterative and incremental testing approach that helps to add great business value to customers. It is a smarter approach than other traditional testing procedures where you are well equipped to handle changes in requirements or scope. LambdaTest platform simplifies the way organizations approach Agile testing.
LambdaTest comes with flexible pricing options that you can choose based on your requirements. You are required to do free signup, and then you can explore the different sets of features. Customer experience has been the topmost aspect of the LambdaTest platform, which is why you will see more and more features that will solve complex customer problems or pain points.
A software approach called agile QA testing aims to incorporate the ideas of agile software development into the QA testing process. Agile testing emphasizes the iterative nature of agile and CI/CD development cycles and tries to match QA with the release cadence.
Changing requirements, Inadequate information, Continuous testing, Technical expertise, Frequent regression cycles, Lack of communication, Lack of quality measurement
Agile teams are being helped to identify where to concentrate testing efforts in each step of the product life cycle, including sprint zero, construction iterations, deployment, and production.
