SIT Regression
Systems Integration Testing (SIT) Regression
The objective of the Regression Testing stage is to ensure that previously passed tests, defects and software still perform as expected after changes have been made. The regression tests are performed to ensure that new code and defect fixes have not introduced new bugs or triggered any previously undiscovered defects that would cause software to regress unintentionally.
