Top Software Testing Techniques Every QA Should Know
Quality and reliability of software become significant when observing the constant shift in technology and developing software. Quality Assurance (QA) specialists’ major goal is to detect and eliminate problems before software delivery to end consumers. This responsibility requires the use of a number of methods of testing. Actually, let’s take a closer look at the set of the most important methods and approaches to software testing, which every QA specialist should know.
1. Manual Testing
Analyzer testing is when test cases are executed with the assistance of human testers without the assistance of tools. The approach is more useful in flagging usability and user interface problems for which automation is less likely to pick out.
Key Components:
Exploratory Testing: Since testers work with the application on a daily basis, they find the different scenarios on their own.
Usability Testing: Refers to the effort made to make the application as easy to use and familiar as possible.
Ad Hoc Testing: Lack of formality and structure, can provide a surprise of new bugs found.
Advantages:
Most suitable for gaining insight into the users’ stance.
Suitable for achieving early feasibility within a small scale or where projects are experimental at best.
2. Automated Testing
Automation testing is the testing of software by using scripts and tools as it is far more effective for repetitive tasks.
Key Features:
Some of the popular tools these tools are Selenium, Testcomplete, and Appium.
Most commonly used in regression testing and benchmarking, and also load testing.
Offers standard results hence minimizing the effects of human intervention.
Best Practices:
Automate those tasks that take more time and energy but do not significantly impact the results.
Maintenance is done by closely updating test scripts to meet changes that have been made in the application.
3. Unit Testing
At the function or method level, unit testing verifies each entity in isolation from all others in the system.
Key Features:
Some of the familiar ones are JUnit for Java, NUnit for .NET, and PyTest for Python.
It tends to guarantee that each unit operates in the right methods when tested individually.
Basic to all error identification for early detection at the time when correction is possible.
4. Integration Testing
Integration testing checks the functionality of software up the combination and how those software units are integrated.
Approaches:
Top-Down Integration: It commences with advanced types of modules and as the program advances, the lower levels of these are incorporated.
Bottom-Up Integration: Start from the lower level of the design then gradually add the higher level component.
Big Bang Integration: Tests all in one but is the least tested type of component combination and interaction in an environment relating to software development structure.
5. Functional Testing
Functional testing checks whether several features of the application match its requirements.
Process:
The second means to verify functionality involves the use of user stories or requirements.
Both global and feature testing cases with APIs, databases, and user paths must be captured.
Tools:
Automated functional testing tools are Selenium, Katalon sStudi,o, and Quick Test Pro (QTP).
6. Performance Testing
Load testing specifically tests system efficiency in performance by assessing the system’s stability or robustness given specific heavy load parameters.
Types:
Load Testing: Evaluate the performance of the system in terms of the predicted number of users.
Stress Testing: Focuses on learning the anticipated behavior of the system in stressful situations.
Scalability Testing: It provides an evaluation of increased loads and their efficient management.
Tools:
Apache JMeter, and Load Runner both from Microfocus, and BlazeMeter.
Importance:
Performance testing helps to know where the problem areas are, in order to have high availability regardless of the number of users which it has to process.
7. Security Testing
From testing for security, one can determine risks and all that needs covering to ensure maximum security.
Key Areas:
Check for the proper authentication and authorization principles.
Test data encryption methods.
The third recommendation is to try attacks in penetration testing.
Tools:
Google DORK, Nmap, and Metasploit are good examples of tools used in security testing.
Importance:
With data breaches in existence, security testing cannot be something that can be ignored in the current world.
8. Usability Testing
Usability testing concentrates on the user experience of the application to increase usage satisfaction and ease.
Process:
Find the participants who are close to the target audience.
Always pay attention to what users are doing in the interaction with the application.
After knowing the basic requirements of the web design, feedback is collected to make the design more refined.
Benefits:
Can assist in locating unclear navigation as well as bad layouts.
Balances the satisfaction of the users and their retention or sticking around on the site or application longer.
9. Regression Testing
Positive regression assurance makes sure that changes in the new code can cause new bugs in previously tested functionality.
Key Features:
Especially useful after getting application fixes or after adding new features.
Software tools like Selenium and Test NG are very helpful to run regression test cases and scripts very effectively.
Challenges:
Needs documentation on test cases.
The system may take a longer time if not automated.
10. Smoke Testing
Smoke testing is used to check the primordial, or core, functionalities of an application in preparation for subsequent testing.
Process:
Intended and conducted directly after a new build.
Pros in that it points out important matters right from the start of the process.
Importance:
Smoke testing helps eliminate the squared digest time spent on unstable builds during later comprehensive test phases.
11. Exploratory Testing
Exploratory testing does not separate test designing, testing, and gaining knowledge all three activities occur at the same time.
Key Features:
Most useful in situations where there are apparent gaps of coverage in the records.
Develops non-linear approaches to navigation between rooms to discover concealed flaws.
Tools:
Though usually performed by hand, there are tools to track exploratory tests for example TestRail.
12. Compatibility Testing
Browser compatibility testing confirms how well the application will run on different equipment, web browsers, operating systems, and networks.
Key Areas:
Cross-Browser Testing: Maintains system’s behavior within different web browsers stable.
Cross-Platform Testing: Supports compliance with given functionality on various operating platforms and gadgets.
Tools:
There are many tools available in the market for compatibility testing among which BrowserStack and Sauce Labs are most popular.
13. API Testing
It confirms the reliability, availability, and reliability of application programming interfaces.
Process:
One must examine input-output behavior, error handling mechanism, and response time.
It is responsible for the smooth coordination of various segments of a software application.
Tools:
Some of the API testing tools include Postman, SoapUI, and RestAssured.
14. Acceptance Testing
Verification testing establishes if the application is okay or not as well as furthering the specifications set by the business aspect.
Types:
User Acceptance Testing (UAT): Carried out by end-users to simply check usability requirements on real-life conditions.
Alpha Testing: Usually performed by internal personnel before the project is let out to the public.
Beta Testing: Refers to true users under actual environment.
15. Data-Driven Testing
Automation of test cases uses data motion to change data inputs.
Benefits:
Enables coverage of more tests with relatively little extra work.
Apache POI or TestNG tools help to include data sets easily.
16. Accessibility Testing
This checks that the client can be accessed by people with disabilities as it validates the application.
Key Focus Areas:
Confirm conformance with accessibility standards for the web including the WCAG standards.
Most features may easily be tested, including screen readers and keyboard navigation.
Tools:
Axe, WAVE, and NVDA.
Emerging Trends in Software Testing
AI-Driven Testing: Test automation and Defect prediction are improved by Tools like Testim by leveraging the power of Artificial Intelligence.
Shift-Left Testing: Fully incorporates testing at the earlier stage of the development and as a result has better fault identification.
Continuous Testing: Broadly a subfield of DevOps, it means that testing is carried out at each phase of the CI/CD process.
