    7. Review and update regularly : As the tool or your testing needs evolve, revisit your customizations to make necessary adjustments.

    Example of a script customization in a pseudo-code:

    function customTest() {
      const testEnvironment = getTestEnvironment();
      const specificRequirement = getSpecificRequirement();
    
      if (testEnvironment.supports(specificRequirement)) {
        runCustomizedTestSequence();
      } else {
        logError("Environment does not support the specific requirement.");
      }
    }

    Remember to validate the compatibility of your customizations with new versions of the test tool and to share useful customizations with the team or the tool's user community when appropriate.
