What is Regression Testing ?

Regression Testing -

Regression Testing is performed on modified build after the bug fixes or major changes in the code.
Regression Testing is carried out to ensure that after changes are done to a system (for bug fixes or enhancements) they do not adversely affect the original functionality or already implemented functionality.

Regression Suite -
 
Test Engineer identifies such scenarios for Regression & creates a separate set of Test Cases to execute during Regression Testing. It is called as "Regression Suite".

Types of Reviews in Testing ?

     During the Software Testing process the Reviews of various documents (Test Plan, Test Cases, Other Testing related documents ) are conducted to identify any mistakes, gaps, improvements and to correct those accordingly.

Following are the types of Reviews,

1. Self Review - 

     Once a Test Engineer creates any Testing document.He/She rechecks the document to ensure that it is complete and correct in all aspects.

This method of Review is called as a "Self Review".

2. Peer Review -

    After completing the "Self Review", Test Engineer shares the document with his peers/teammates.Peers then verifies the document and send review comments to the Testing Engineer(owner of the document).

   According to the review comments, Test Engineer makes changes to the document.

This review method is called as "Peer Review".

3. Walk-through -

   "Walk-through" is an informal meeting for evaluation, usually no preparation is required for this.

Comments, suggestions or issues raised by Participants are captured and published in a report.

4. Inspection -

   "Inspection" is a formal method of Review for improving the document/product by continually measuring it against standards and requirements.
