In our last QA blog post, we have given you a more than general overview of what QA is and explained why your software needs a QA engineer.
Today, we will tell you about various types of testings that a QA engineer can perform. So here they are:
- Functional testing: This type of testing focuses on verifying whether the software meets the specified requirements and performs as intended. This type of testing involves checking the software’s functionality by giving the input value and validating the output with the expected result.
- Unit testing: Unit testing focuses on verifying the functionality of the smallest functional unit of code or software component. Unit tests are usually written by developers and are used to validate the functionality of the code. This type of testing helps to expose defects during the initial development phases.
- Integration testing: Integration testing focuses on verifying the integration of different components or units of the software. Integration testing is performed to ensure that the software works correctly when different components are combined. This type of testing helps to expose problems with data formats, operation timing, API calls, database access, and user interface operation issues.
- Regression testing: This type of testing is performed to make sure that the changes that have been made to the software have not impacted the existing functionality. This may include retesting existing functionality to ensure that it still works as expected. This type of testing helps to expose any defects that may have been unintentionally introduced into the existing build and ensure that previously removed defects do not occur again.
- System testing: System testing focuses on evaluating the behavior and capabilities of the software as a whole system, including all its components and interfaces. System testing is performed to ensure that the software meets the specified requirements and behaves as expected. This type of testing helps to verify whether the functional and non-functional behavior of the system is as designed and specified.
- User acceptance testing (UAT): This type of testing focuses on evaluating the software from the user’s perspective. UAT is performed by actual users of the software to ensure a real-life representation of how well your software works in day-to-day situations. This type of testing helps to build confidence that the users can use software with minimum difficulty, cost and risk.
- Non-functional testing: This type of testing focuses on evaluating the non-functional aspects of a software, such as performance testing, usability testing, efficiency testing, security testing, etc. The goal of non-functional testing is to ensure that the software meets the specified requirements and can operate effectively in a real-world environment.
The two essential approaches used by QA engineers to validate the functionality and performance of the software are manual and automation testing.
- Manual testing involves the manual execution of test cases by a QA engineer to verify the expected results, while
- Automation testing involves the use of specialized software tools to automate the execution of test cases. Automation testing is best suited for repetitive and time-consuming tasks.
QA engineers play a critical role in the design, implementation, and maintenance of automated tests. Test automation is a key component of a QA engineer’s responsibilities. This includes creating and updating test scripts and test data, adding new test cases, and improving the overall testing process.
Test automation is an ongoing process, and QA engineers must continually assess and improve automated tests to ensure that it is providing the most accurate and efficient testing results possible. Once automated tests are created, manual testing time is reduced and efficiency and accuracy are increased.
