Regression testing - it is a must!
Regression testing is a crucial aspect of Quality Assurance that ensures that the software maintains its functionality after any modifications, updates or enhancements have been made. Regression testing purpose is to identify any new defects or issues that may have been introduced into the software due to those changes.
Regression testing is a type of software testing that re-executes the existing test cases that have been already passed or executed successfully in the previous versions of the software. The objective of regression testing is to ensure that the new changes or modifications have not adversely affected the existing functionality of the software.
When to perform regression testing?
Regression testing is typically performed when there are changes made to the software or its environment. For example, a regression test may be required after an update to the operating system, browser, or any other application that interacts with the software. Regression testing may also be needed after any code changes, modifications, or bug fixes.
Is automated regression testing better than manual?
Both automated and manual regression testing have their advantages and disadvantages. Automated testing is faster, more efficient, and more consistent than manual testing. Automated testing can also be more cost-effective, especially in the long run. On the other hand, manual testing is more flexible and adaptable than automated testing. Manual testing can be better suited for testing complex or less-defined scenarios. But one of the key advantages of automated testing over manual testing is the repeatability of the tests. This provides a high level of test coverage and saves time.
Ultimately, the choice of regression testing method should be based on the goals, resources, and constraints of the software development project.
Differences between Sprint Level Regression and End-to-End Regression
Sprint Level Regression
Sprint level regression is a type of testing that is performed at the end of each sprint in Agile development. The purpose is to ensure that the software being developed still meets all the requirements and functionality that were specified at the beginning of the sprint. This type of testing helps to catch any issues or bugs that may have been introduced during the sprint, and ensure that they are addressed before moving on to the next sprint.
End-to-End Regression
End-to-end regression testing is a type of testing that is performed to ensure that all aspects of the software are working together as intended. This type of testing covers the entire software system, from the user interface to the back-end functionality. The purpose of that kind of testing is to verify that all the different components of the software are communicating with each other correctly and that the system as a whole is functioning as expected.
End-to-end regression testing is typically done using both automated and manual testing techniques. Manual testing can be used to verify the functionality of the user interface and other aspects of the software that require human interaction.
