Program Testing and Debugging in System Programming

Program Testing and Debugging :-

•  The important parameters are the selection of test data for the
program analysis of test result to detect errors and debugging.

•  For program testing, the selection of test data for program and
analysis o test results to detect error if any is important.

• User uses the software tools for this purpose.

1) Test data generators.
2) Automated test drivers.
3) Debug monitors.
4)  Source code control.

•  Test data generators help the programmer in selecting test data.

• Regression testing is done through automated test drives. in this,
program correctness is verified by subjecting it to a standard set of
tests after every modification.

• Obtaining the  information about localization of error, debug monitor is used.

• Source code control system help to keep track of modification
in the source code.
