Looking at Look4Success Server Action of HTTP_Invoke of TestFramework, the test scenario is executed using GetRequest_Submit of HTTPRequestHandler API, and the existence of "ALL SCENARIOS PASSED" string is checked in TextContent which is the execution result of GetRequest_Submit. This check is not working properly, so the BDD scenario appears to be determined to be Unclassified even though it has completed successfully.
Regex_Search is used to check the existence of the "ALL SCENARIOS PASSED" string, but the second parameter Pattern is not "ALL SCENARIOS PASSED" but "ALL \ s * SCENARIOS \ s * PASSED", isn't it?
