how to stop exporting failed test cases result to a file in - FAIL.txt in afterStep

Hi kannan ! I am not sure there's an easy way to achieve what you'd like. However, if you are using our plugin, you can try using test runners as its alternative and get the needed reports through parameters.

An article on test runners, hope this is helpful - https://support.smartbear.com/readyapi/docs/integrations/jenkins.html#command-line
