What is the difference between end to end testing and regression testing?

System testing- checks end to end flows works as expected. Acceptance testing- to validate the system is developed as per business requirement. Regression testing- performed to check the integration of all modules and modifications or enhancements in Module 1 has not led to code break.

What is regression testing used for?

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.

What is functional vs regression testing?

Is functional testing white box?

White-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of software testing that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing).

How do you manually perform functional testing?
