Whenever any updated software is revealed, it becomes evident to test its features. The need to check new features is apparent any time new software is released. It is, therefore, equally imperative to re-execute old tests previously passed by the applicant. We can be confident that the latest software does not re-introduce old bugs or build new ones in the program. This type of software testing is called “Regression Testing.”
The term “Regression Testing” is described as a kind of software test to confirm that the current features have not been adversely affected due to a new program or change in code.
The primary examples of regression testing are iteration regression & full regression. So, the partial or complete set of test cases are already executed or re-executed to ensure the current functionality works correctly. This check has performed to ensure that new code updates are not likely to have side effects on existing features. It makes sure that the previous code will still work once the latest changes in code have made.
Benefits: Regression testing is beneficial for the organizations in a number of ways .Such as it identifies a bug in the software and ensures the accuracy so that the best model of software is revealed in the marketplace. Early detection and correction of bugs ensures good performance of software.
Application: Regression testing is recommended to apply in case of patch fixing, defect fixing, or to overcome the performance issues in software. Regressing testing is also applied whenever updated features are introduced in a software or environment changes are required.
Types: Regression testing is implemented through several phases, that’s why it has many types. Some types include:
Conclusion: An effective regression testing strategy helps the origination to save the both time & money. Regression testing is helpful for early detection and correction of bugs that ensures good performance of software.
