A test appears as "Running" in the tests results list until it is completed or aborted. If you see tests that remain in a "Running" state even after they were completed or terminated, this means you either did not call eyes.close at the end of the test or did not call eyes.abortIfNotClosed in case of an abnormal test termination.
After all tests are completed, ensure that you call eyes.getAllTestResults() to close the batch.
Please refer to the SDK guide for instructions on how to properly use these methods in you preferred programming language.
