| Calling this test function finds and runs all tests associated with the |
| module and all its sub-modules. |
| |
| Attributes |
| ---------- |
| module_name : str |
| Full path to the package to test. |
| |
| Parameters |
| ---------- |
| module_name : module name |
| The name of the module to test. |

| Run tests for module using pytest. |
| |
| Parameters |
| ---------- |
| label : {'fast', 'full'}, optional |
| Identifies the tests to run. When set to 'fast', tests decorated |
| with `pytest.mark.slow` are skipped, when 'full', the slow marker |
| is ignored. |
| verbose : int, optional |
| Verbosity value for test outputs, in the range 1-3. Default is 1. |
| extra_argv : list, optional |
| List with any extra arguments to pass to pytests. |
| doctests : bool, optional |
| .. note:: Not supported |
| coverage : bool, optional |
| If True, report coverage of scikit-image code. Default is False. |
| Requires installation of (pip) pytest-cov. |
| durations : int, optional |
| If < 0, do nothing, If 0, report time of all tests, if > 0, |
| report the time of the slowest `timer` tests. Default is -1. |
| tests : test or list of tests |
| Tests to be executed with pytest '--pyargs' |

| Returns |
| ------- |
