Different Types of Software Testing

Software testing is a technique to validate websites or mobile applications, identify bugs or issues, and ensure they work as intended. This process is a critical part of the Software Development Life Cycle. However, there is not just one type of software testing to efficiently test the different components of software applications at various phases of the development process.

Based on the diverse requirements and purposes, there are different types of software testing. Each type serves a unique purpose, from unit and integration to performance and user acceptance testing. Understanding the significance of these diverse types of software testing is imperative for developers and testers.

What Is Software Testing?

Software testing is the process of ensuring that software applications are functional, reliable, and of high quality. This process involves finding errors and vulnerabilities to ensure the software application meets the user’s expectations before going live.

Testers perform software testing through manual or automation techniques to ensure the software application functions as intended. This involves careful planning, test case creation, running of test script, and debugging, etc. Following tests, testers communicate results to the development team for further modifications, aiming to deliver a high-quality software application to the users.

It is an essential part of the Software Development Life Cycle (SDLC) and provides necessary mitigation against possibly business-impacting bugs that would otherwise go undetected.

Types of Software Testing

The field of software testing is exceptionally robust and includes different categories based on other purposes and aims. Here, we will discuss various types of software testing.

Functional Testing

Functional testing focuses on evaluating the functional aspects of a software application. This type of testing checks the various functions of the software application, such as user interfaces, client/server applications, and functionality. Functional tests can be performed manually or automated using tools. The primary concern in functional testing is understanding what the software system does and how effectively it performs its designated functions.

Functional testing offers the following advantages:

• Identifying software application functionality issues before they escalate into major issues.
• Verifying that required features work as expected and evaluating the system’s ability to handle unexpected conditions.
• Ensuring the software applications meet end users’ expectations and are bug-free.
• Testing the software applications effectively under various conditions and scenarios.
• Monitoring progress and adjusting testing plans as needed.

Types of Functional Testing

There are many different types of functional testing, which include the following:

• Unit testing: It evaluates the smallest functional unit of code, a crucial step in software development that ensures code quality. This test involves writing software in small, functional units and creating a corresponding unit test for each code unit. Initially, these unit tests are written as code and then automatically executed whenever changes are made in the software code. This approach quickly identifies bugs or errors within the code if a test fails.

The following are the types of unit testing:

• Branch testing: Ensures all possible branches in the code execute at least once, verifying correct behavior in all conditions.
• Gorilla testing: Focuses on stress-testing a specific module to detect bugs and assess performance under extreme conditions.
• Statement testing: Executes every statement in the code at least once to ensure complete test coverage.
• Expression testing: Checks syntax expressions to prevent errors and ensures only valid expressions are accepted.
• Pattern testing: Identifies recurring error patterns by analyzing past defects, helping prevent similar issues.
• Matrix testing: Evaluates software variables to assess technical and business risks, optimizing their usage.
• Integration testing: It take place once software modules are integrated to ensure they function as expected. Compared to unit tests, integration tests focus on aspects like evaluating database interactions and ensuring the seamless working of microservices. These tests can be relatively expensive because multiple application components need to be operational. Jasmine and Mocha are considered suitable tools for integration testing.

This testing category includes various approaches, such as the top-down, bottom-up, and sandwich approaches.

• Component testing: Tests individual modules separately before integrating them. It ensures each part works correctly on its own.
• System integration testing: Checks if all integrated components work well together. It helps confirm the system meets the requirements.
• Incremental integration testing: Tests one module before adding another. Each integration is verified step by step to catch issues early.
• Bottom-up integration testing:Starts testing from the lowest-level modules. Higher-level components are added gradually to build a stable system.
• Top-down integration testing: Begins testing with the main components first. Lower-level modules are integrated later to verify interactions.
• Sandwich integration testing: Uses both top-down and bottom-up testing. This approach balances component-level and system-level validation.
• Non-incremental integration testing: Merges all modules at once before testing. It can make issue detection more difficult.
• End-to-end integration testing: Validates the entire system and its connections with external tools. It ensures everything works as expected.
• System testing: System testing is the process where a complete and integrated software system is tested to verify that it meets specified requirements. It is executed within the framework of a System Requirement Specification (SRS) and a Functional Requirement Specification (FRS).

This testing phase follows integration testing and is then followed by acceptance testing, focusing on identifying issues within the integrated units of a system.

Here are different types of system testing.

• End-to-end testing: Validates the entire software application by simulating real user interactions. Ensures smooth functionality before release.
• Smoke testing: Checks if a new build is stable enough for further testing. Runs basic tests to confirm core functionality.
• Sanity testing: Verifies that recent bug fixes or minor changes did not break the software. Focuses on key functionalities.
• Monkey testing: Feeds random inputs to test system stability. Helps identify hidden issues not covered in regular testing.
• Happy path testing: Tests the system under ideal conditions with valid inputs. Ensures expected outputs without errors.
• Acceptance testing: As your product nears completion, it’s time to consider real user feedback. This is where acceptance testing plays a role, aiming to evaluate whether the software application is ready for real-world use.

The focus is confirming whether the software applications align with user expectations and efficiently execute the intended tasks. End users perform this testing to validate and approve the software application before the developer transitions it to the production environment.

• Alpha testing: Conducted by an internal QA team in a controlled environment to find and fix bugs before release. Uses both white-box and black-box testing.
• Beta testing:Real users test the software before release to identify hidden bugs and usability issues. Their feedback helps improve the final product.
• User acceptance testing: End-users validate the software to ensure it meets their needs. It is done at the final stage before deployment.
• Regression testing: Regression testing is a type of software testing that verifies recent code changes haven’t affected existing features. It involves re-executing a selection of previously executed test cases to ensure the functioning of existing features. The testing is crucial to confirm that new code changes do not produce any impact on existing functionalities.

Non-Functional Testing

Non-functional testing is one of the types of software testing that checks whether the software application’s non-functional aspects, such as stability, security, and usability, are functioning as anticipated. These tests occur post-functional testing and focus on enhancing software application quality. The primary objective is to evaluate a software application’s readiness based on non-functional criteria that functional testing typically overlooks.

Non-functional testing offers the following advantages:

• Providing a higher level of security safeguarding systems against online threats.
• Ensuring the system’s capability to handle concurrent user usage without performance degradation.
• Contributing to the enhancement of the system’s overall efficiency.

Types of Non-Functional Testing

Here are the different types of non-functional testing:

• Performance testing: Performance testing is one of the types of software testing to check how well a software application maintains stability, speed, scalability, and responsiveness under specific workloads. In other words, it includes different tests that check the speed, robustness, reliability, and appropriate sizing of the software application.

It involves the evaluation of several indicators, including browser, page, and network response times, server query processing time, the capacity to handle an optimal number of concurrent users, CPU memory consumption, and the identification and categorization of errors that may occur during the application’s use.

Here are the types of performance testing:

• Load testing: Evaluates how software performs under expected user traffic. It helps identify performance issues and improve reliability.
• Stress testing: Pushes software beyond normal limits to check its robustness. It helps detect failures under extreme conditions.

The following are the types of stress testing:

• Application stress testing: Application stress testing focuses on uncovering defects related to data locking and blocking, network issues, and performance bottlenecks within an application.
• Transactional stress testing: Transactional stress testing involves stress testing one or more transactions between two or more applications, aiming to fine-tune and optimize the system.
• Systemic stress testing: Systemic stress testing, as integrated stress testing, is performed across multiple systems running on the same server. It is used to identify defects where the data of one application blocks another application.
• Exploratory stress testing: Exploratory stress testing evaluates the system with unusual parameters or conditions unlikely to occur in a real scenario.
• Scalability testing: It is a type of non-functional testing that checks how well software applications or networks perform as the number of user requests is adjusted, either increased or decreased. The primary goal of scalability testing is to verify the system’s capability to manage anticipated rises in user traffic, data volume, transaction counts, and frequency. This testing evaluates the software application’s ability to adapt to growing demands.
• Volume testing: Volume testing is a form of software testing where the software application undergoes testing with a significant amount of data, also known as flood testing. The objective is to understand the system’s performance by increasing the volume of data in the database.
• Soak testing: Soak testing, also referred to as capacity testing or longevity testing, involves evaluating the software application to identify performance-related issues such as stability and response time by applying the intended load on the software.
• Throttle testing: Throttle testing involves simulating a load scenario where virtual users, either all of them or a specific group, connect with a restricted connection speed.
• Peak testing: This type of software testing evaluates how the software application responds to intensity peaks alongside a regular load. This test demonstrates the functionality of software applications after facing an increased load.
• Spike testing: In this test, software application is tested with extreme increases and decreases in traffic load. The primary goal of spike testing is to understand how the software application behaves when faced with sudden increases or decreases in user load and to figure out the recovery time after a spike in user load.
• Stability testing: This checks the quality and behavior of the software in different environmental parameters, evaluating the software application’s ability to continue functioning over time without failure.
• Endurance testing: This type of software testing evaluates the system’s ability to handle a sustained workload over an extended period.
• Usability testing: Usability testing, also referred to as user experience (UX) testing, involves evaluating the functionality of a website or web app by observing actual users as they engage with it to accomplish tasks.

Typically, in this testing approach, a select group of target end-users actively engages with the software application to uncover potential usability defects. Here, the primary focus of usability testing is evaluating the user interface and the overall user experience of a software application. Consequently, the testing process involves real users interacting with the software application to measure its ease of use, efficiency, and overall user satisfaction.

Here are the types of usability testing:

• Exploratory testing: It also called ad-hoc testing, is a form of software testing where the tester can choose any available methodology to test the software. It represents an unscripted approach to software testing.

In this type of software testing, developers utilize their learning, knowledge, skills, and abilities to evaluate their developed software applications. This testing method checks the functionality and operations of the software while identifying functional and technical faults.

• User Interface (UI) testing: It is a type of software testing that concentrates on verifying the appearance, functionality, and usability of various user interfaces, including graphical user interface (GUI), command line interface (CLI), and voice user interface (VUI).
• Accessibility testing: It is described as a type of software testing carried out to ensure that the software application being tested is user-friendly for people with disabilities, such as those with hearing impairments, color blindness, elderly individuals, and other disadvantaged groups.
• Compatibility testing: It is one of the crucial non-functional tests that ensure your software application can operate seamlessly across diverse hardware, operating systems, applications, network environments, or mobile devices.

There are two categories of version checking in compatibility testing:

• Backward compatibility testing: It involves verifying the behavior and compatibility of the developed hardware or software with its older versions. This type of testing is more predictable since all the changes from the previous versions are known.
• Forward compatibility testing: This is a process to validate the behavior and compatibility of the developed hardware or software with the newer versions. This type of testing is somewhat challenging to predict as the specific changes in the newer versions are not known in advance.

The following types of compatibility testing:

• Cross-browser testing: Cross browser testing verifies the functioning of websites across various browsers, operating systems, and devices. It includes testing the website’s functionality, performance, and user interface on various web browsers like Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera.

You can perform cross browser testing in the cloud because it provides convenient software application testing across various browsers and versions without any worry about local infrastructure.

One of the most used cloud-based platform is LambdaTest – an AI-native test execution platform that enables you to perform manual and automation testing for web and mobile applications across on-demand real browsers, devices, and operating systems on its scalable cloud grid. It offers support for automating test scripts with various testing frameworks like Selenium, Playwright, Cypress, Appium, Espresso, XCUITest, and more.

You can run automation tests with diverse programming languages and frameworks on an online browser farm comprising 5000+ real desktop and mobile environments.

• Cross-platform testing: Cross-platform testing is a testing type that ensures that an application or software application works correctly across diverse platforms, operating systems, and devices. It includes testing the application’s functionality, performance, and user interface on different platforms such as Windows, macOS, Linux, Android, iOS, and others.

Testing for responsiveness allows you to modify the screen’s width after entering the website’s URL, observing how the user interface adjusts in real-time.
• Visual testing: Visual testing verifies if every user perceives the software application’s interface (UI) correctly. This type of testing checks that each element on a web page has the correct shape, size, and placement. Visual testing evaluates software application’s visible output against the expected design outcomes, helping identify “visual bugs” separate from strictly functional bugs in the appearance of a page or screen.
• Security testing: It is a type of software testing that checks the vulnerability of the software application against cyber threats. This is done by evaluating its susceptibility to attacks and the impact of malicious or unexpected inputs on its functionality.

It offers assurance regarding the safety and reliability of software applications and their resistance to unauthorized inputs. The primary focus of security testing lies in uncovering potential weaknesses and loopholes within software applications that could lead to loss of information or hamper the organization’s reputation.

The following are the types of security testing.

• Penetration testing: Penetration testing is one of the types of software testing that involves simulating attacks on software applications to obtain access to sensitive data, aiming to ascertain the software applications’ security status. These attacks can be executed internally or externally, giving information on the target system, pinpointing vulnerabilities, and revealing potential exploits that might impact the software applications.
• Fuzz testing: This process includes sending numerous unexpected or malformed input data to the software applications to uncover potential input validation and handling vulnerabilities. A fuzzing tool sends these inputs into the software applications and observes for exceptions like crashes or information leakage.
• Access control testing: This includes testing the access control mechanisms of the software applications to ensure that access to sensitive data is granted only to authorized users. It enables the configuration of access rules and executes a comprehensive attack to assist in identifying sections of software applications that may be accessible by unauthorized clients.
• Application security testing: Application security testing (AST) aims to enhance the resistance of software applications against security threats by pinpointing weaknesses and vulnerabilities in the source code. These approaches involve testing, analyzing, and reporting on the security status of a software application throughout the Software Development Life Cycle (SDLC). There are two primary approaches:
• Static Application Security Testing (SAST): It uses a white box testing approach, where testers evaluate the inner workings of software applications. It inspects static source code and provides reports on security weaknesses.
• Dynamic Application Security Testing (DAST): It adopts a black box testing approach, executing code and inspecting it in runtime to detect potential security vulnerabilities. This includes validating issues related to query strings, requests and responses, script usage, memory leakage, cookie and session handling, authentication, execution of third-party components, data injection, and DOM injection.
• API security testing: This is one of the types of software testing that has a crucial role in uncovering vulnerabilities within software application programming interfaces (APIs) and web services. This helps the developers address and fix these vulnerabilities.
