Regression testing is the process of testing changes to computer programs to make sure that the older programming still works with the new changes.

Smoke testing is non-exhaustive software testing, ascertaining that the most crucial functions of a program work, but not bothering with finer details.

 
Sanity Testing is the processes of checking the basic functionality of the application. This testing are done before the application is cleared for in depth testing.

Regression testing- Modification in one portion of the software  have no bad effect in another portion of software.

I do a lot of regression testing when we release patches.  Basically verifying that the patch did not introduce other bugs either related or unrelated.

For example if you change the brand and tread of tires on your car are you still getting the same miles per gallon, and handling?  Does the tire now hit the wheel housing when going over bumps etc...

You can go as far as to test if the doors still open and close as designed but most companies willnot support the cost of regression testing that far.  But an organization like nasa might because people's lives are on the line so regression testing needs to go to the nth degree and as a result engineering changes are less likely to be accepted because of the regression testing impact and the possible introduction of new problems.

I have not heard of smoke or sanity testing but I can take a guess.

plug it in and see if there is smoke?  Meaning are the systems bugs that glairingly obvious on the surface you can pretty much assume we are screwed on the lower level detail.

Sanity testing could be checking back with the users to still see if they want the system.  Sometimes the need for a system is very political and as organizational changes are made system projects can get cancelled just like that.

Regression testing

is any type of software testing which seeks to uncover regression bugs. Regression bugs occur whenever software functionality that previously worked as desired, stops working or no longer works in the same way that was previously planned. Typically regression bugs occur as an unintended consequence of program changes.

Common methods of regression testing include re-running previously run tests and checking whether previously fixed faults have re-emerged.

perform already testing functionality just make sure that it is refind to the perception &also existing functionality is uneffect due to the new functionality is added to it
