Hello gurus,

wht is the diff b/w regression and non regression testing?

Hi,

Regression testing is reffered to a test which verfies that some new configuration does not adversly impact existing functionality. This will be done on each phase of testing.

Non Regression testing referred to after changing some functionality in the application. Here have to retest the changing functionality/module/build.

Hi,

Normally regression testing is applicable only for rollout projects or phase by phase implementaiton methods.

For example, you have five plants and you have implemented SAP for three plants, for the remaining two plants now you are palnning to implement SAP.

Now you can use regression testing to test is there any imapcts for the already implemented plants. For this you need to move all the configs to testing server.

There is no such terminology called non regression testing, the other types of testing are unit testing, Integration testing, load/stress testing, user acceptance testing.

Non-regression testing is used when components of the systems

when new components (and functionality) are added to the system. It aims at asserting both that changes are correct and that no regression bugs appear in the system due to the recent evolution. Generally previous test sequences are launched to guarantee that the system has not regressed in terms of testing quality.

After changing some functionality in the application we'll go for regression to verify the bugs and its impact on the other functionality of the application.

Example : If release of the project is expected soon we don't get as much time to test the whole application again. At that time the decision may be taken by tester with lead that dont go for regression i.e. Non Regression Testing.

In such a case only we have to retest the changing functionality/module/build
