Testing for Regressions

The recommended approach for regression testing with the Intel® Inspector involves these basic steps:

  1. Create a gold standard:

    • Use the GUI (or the inspxe-cl command) to create a result from which you have successfully eliminated all real problems.

    • Use the inspxe-cl command to create a suppression file to match any remaining problems you have determined you can ignore.

  2. Change your source code.

  3. Use the inspxe-cl command (or the GUI) to check for new problems:

    • Apply the suppression file when you run a new analysis.

    • Determine if the changed source code introduced new problems that do not match those in the suppression file.

Intel Inspector also offers alternative ways to test for regressions.
