Complete Regression Testing
This is the perfect method when there are many modifications in the specifications. Especially when the root codes are affected. This is favorable to recognize unanticipated issues. Once completed, the system will finally be publicized to the end user.
Make sure to select the proper regression testing type to be carried out based on the need of your deliverable. The highest priority is to ensure that a software delivered is with the best features and should prove to be beneficial to the industry.
How to Optimize Regression Testing?
There are different approaches that can optimize regression testing which will help the team to assure that the product is of quality.
● Test Prioritization: a Two-level approach
With this, the regression team will break the test into two cycles:
1) Iteration Regression. This is where regression testing is done at the end of each sprint. The focus primarily is on the modifications created in the iteration as well as the areas that can be affected by the changes.
How to Optimize Regression Testing?
● Test Prioritization: Two-level approach
2) Full Regression. Before release, a full regression is run to ensure that the product is working as planned.
● Test Prioritization: Risk-based approach
With this, the test team choose the test cases affected by the modifications in the application based on priority, where time and effort are reduced. There are three categories:
1) High Priority. The test cases here are the crucial functions of the application. These areas include: defect-prone, highly perceptible to end users, and affected by many changes. About 10% of the system.
2) Medium Priority. These test cases are areas that are mostly affected by bugs detected on the previous releases. About 30% of the system including the negative tests, boundary, etc.
These two are covered in the test suite for the agile regression or also called a mini-regression.
3) Low Priority. The 60% of the remaining test cases of the functionality. Test engineers use these for the full test prior to a major release.
