    Regression testing is that testing that is performed after making a functional improvement or repair to the program. Its purpose is to determine if the change has regressed other aspects of the program. It is usually performed by rerunning some subset of the program's test cases. [G. Myers]

    Selective testing to verify that modifications have not caused unintended adverse side effects or to verify that a modified system still meets requirements. [B. Hetzel]

    Regression testing refers to retesting of the bug which is fixed. At the same time, testing the other parts of the application to ensure that the fix doesnt impact other functionalities

    Regress in english means :
    1. To go back; move backward.
    2. To return to a previous, usually worse or less developed state.
    3. To have a tendency to approach or go back to a statistical mean.

    Regression testing means that the change or upgrade has not caused any existing functionality ( that was already working before) to break .

    In a sense , the software should keep upgrading ( move forward ) rather than degrading ( move backward) [img]/images/graemlins/smile.gif[/img]

    Functional Testing Process:
    In functionally testing following steps must be observed:
    1) Understand the Requirements
    2) Identify test input (test data)
    3) Compute the expected outcomes with the selected test input values
    4) Execute test cases
    5) Comparison of actual and computed expected result
