Pure Execution

All regular execution options temporarily store and maintain execution data on the disk so that request and response data is available for review. If response data is not important for your scenario, you can use menu options for execution without storing data on disk (pure execution). All types of pure execution will use all available execution engine features (parameters, chaining, validations, etc.); the only difference is that execution data won't be available for review because no data will be stored on the disk.
You can permanently enable pure execution for the project in project options. In such a case, request and response data will never be stored; even with regular execution types data won't be available for review.
