No tests found. How to fix it?

Answer 1

From the log, we can see that the python script has failed

collected 99 items / 4 errors

And from Jenkins point of view, if any error is encountered, it will give failure as Jenkins uses /bin/sh -xe by default.

So by adding the #!/bin/sh before calling the python script might help in resolving this issue :

    #!/bin/sh
    py.test tests
