Troubleshoot “NO TESTS RAN” errors
On the App Automate dashboard, the Tests/Sessions field tells you the number of tests that have passed or failed. However, if your tests do not run at all, then you see the No Tests Ran error in the Tests/Sessions field. The test details section shows either of these two error messages:
Error 1: No test cases were executed
Here is the complete error:
No test cases were executed. If you are trying to filter test-cases by using class, package, annotation or size parameters, please specify valid parameters and execute the test again. Check https://www.browserstack.com/docs/app-automate/espresso/select-test-cases for reference.
-
If you encounter the above error, it may be due to an incorrect usage of the filtering parameters in your REST API request. Please verify if you used the correct filtering parameters.
-
If the error is not related to the filtering parameters, run the command below in your terminal by replacing the values with your
class_name,test_package, andrunner_class. The output helps you find the cause of the error:
adb shell am instrument -w -r -e class <class_name> -e log true <test_package>/<runner_class>
Error 2: Could not start a session
Here is the complete error:
Could not start a session: Something went wrong. Please try to run the test again.
