Software debugging & Defect Testing Process
Software debugging
When defects have been found in a program, they must be removed. This is called debugging. Defect testing and debugging are sometimes considered to be parts of the same process, in fact they are quite different. Debugging is concerned with locating and correcting these defects
Locate - Design - Repair - Repair
error- error re-test program
Defects in the code must be located and the program modified to meet its requirement.
The debuggers must generate hypothesis about the observable behavior of the program then test these hypothesis in the hope of finding the fault which caused the abnormal output. Interactive debugging tools which show the intermediate values of program variables and a trace of the statement executed may be used to help the debugging process.

The skilled debugger look for patterns in the test output where the defect is exhibited and uses knowledge of the defect, the pattern and the programming process to locate the defect.
