How to configure xml Report in jenkins

I am trying test my python script using jenkins.Issue I am facing is with the test report generation

I have created a folder 'test_reports' in my jenkins workspace. C:\Program Files (x86)\Jenkins\jobs\PythonTest\test_reports

But then when I run the script from jenkins I get the error as, ERROR: Step ‘Publish JUnit test result report’ failed: No test report files were found. Configuration error?

How do I actually configure the test report? Is the xml file generated automatically?

Any help would be greatly appreciated
