What is performance regression testing?

Performance regression testing is a comparative approach that examines how a software application performs across in successive builds. This is done by simulating a variety of usage scenarios, many of which are tests that place the application into adverse performance conditions.Click to see full answer. Accordingly, what is meant by regression testing?REGRESSION TESTING is defined as a type of software testing to confirm that a recent program or code change has not adversely affected existing features. Regression Testing is nothing but a full or partial selection of already executed test cases which are re-executed to ensure existing functionalities work fine.Subsequently, question is, what is regression testing with example? Regression testing verifies that recent code changes haven’t altered or destroyed the already existing functionality of a system. Regression testing examples include iteration regression and full regression, and both can be covered with manual and automated test cases. Similarly, you may ask, why do you do regression testing? Regression Testing is a type of testing that is done to verify that a code change in the software does not impact the existing functionality of the product. This is to make sure the product works fine with new functionality, bug fixes or any change in the existing feature.How do you test software performance? To use a testing environment for performance testing, developers can use these seven steps: Identify the testing environment. Identify performance metrics. Plan and design performance tests. Configure the test environment. Implement your test design. Execute tests. Analyze, report, retest.
