Regression Testing is characterized as a kind of programming testing to affirm that an ongoing project or code change has not antagonistically influenced existing highlights.
Regression Testing is only a full or fractional determination of effectively executed experiments which are re-executed to guarantee existing functionalities work fine.
This testing is done to ensure that new code changes ought not effectively to affect the current functionalities. It guarantees that the old code still works once the new code changes are finished.

Instructions to do Regression Testing
Programming support is a movement that incorporates improvements, mistake revisions, streamlining and cancellation of existing highlights. These changes may make the framework work mistakenly. Consequently, Regression Testing gets important. Relapse Testing can be completed utilizing the accompanying procedures:
Retest All
This is one of the techniques for Regression Testing in which every one of the tests in the current test pail or suite ought to be re-executed. This is pricey as it requires tremendous time and assets.
Regression Test Selection
Rather than re-executing the whole test suite, it is smarter to choose some portion of the test suite to be run
Experiments chose can be ordered as 1) Reusable Test Cases 2) Obsolete Test Cases.
Re-usable Test cases can be utilized in succeeding relapse cycles.
Out of date Test, Cases can’t be utilized in succeeding cycles.
Prioritization of Test Cases
Organize the experiments relying upon business sway, basic and much of the time utilized functionalities. Determination of experiments dependent on need will significantly diminish the relapse test suite.
