Do you often miss bugs when doing regression testing due to inaccurate scope evaluation? Are you worried about the regression test cases when you are facing a regression test? Don't worry, accurate testing makes regression testing no longer difficult! !
1: What is an accurate test?
During regression testing, testers often evaluate the scope of testing that needs to be regressed according to the scope of changes given by developers. At this time, if the testers are inexperienced or the developers change, they will not understand the specific scope of the code. . May make the regression range incomplete or redundant. So we tried to introduce the concept of precise testing. The use cases that need to be regressed can be directly and precisely located according to the range of code changes, which makes the time required for regression testing shorter and the range of regression more accurate.
Two: how to achieve accurate testing
When we have a series of correspondences between use cases and functions, we will have a clear location for the scope of a use case that can be tested. And we can easily count the scope of changes to the project code after one commit of code. So is there a clear inverse relationship for whether we have tested a valid regression range? The answer is yes! So now that the concept and method have been clarified, what we need is a good design and a clever technical implementation.
Three: With the accurate test to help us avoid problems
Regression omission: It may be due to the code written by the developer a long time ago or due to the handover of the code written by others, resulting in the modification of a function but the lack of complete positioning of the scope of the function's impact, which leads to possible use cases or scenarios. Not covered by regression scope.
Regression redundancy: I know the specific scope of influence, but I don't know what the specific influencing factors are when returning, so I can only run most or even all the use cases of the influencing factors, which directly causes a lot of waste of manpower and time. Regression use cases cannot be pinpointed.
Uncertain regression coverage: After each run, you can collect all the functions experienced by the use case, and count the coverage of the use case to check whether the use case is fully covered.
Four: Summary
Accurate testing has always been a challenging topic in the testing industry, and various difficulties will continue to be encountered along the way. However, in an era of rapid development, continuous advancement and continuous improvement are the driving force for our technological improvement. Today, we have proposed the concept of accurate testing. In the industry, third-party testing service providers such as TestBird are also making testing services more accurate and rapid. I hope that students can expand more changes and breakthroughs from this.
