class_docstr: Pytest test runner.
  
  A test function is typically added to a package's __init__.py like so::
  
    from numpy._pytesttester import PytestTester
    test = PytestTester(__name__).test
    del PytestTester
  
  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.
  
  Notes
  -----
  Unlike the previous ``nose``-based implementation, this class is not
  publicly exposed as it performs some ``numpy``-specific warning
  suppression.

docstr: 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 NumPy 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
  -------
  result : bool
      Return True on success, false otherwise.
  
  Notes
  -----
  Each NumPy module exposes `test` in its namespace to run all tests for
  it. For example, to run all tests for numpy.lib:
  
  >>> np.lib.test() #doctest: +SKIP
  
  Examples
  --------
  >>> result = np.lib.test() #doctest: +SKIP
  ...
  1023 passed, 2 skipped, 6 deselected, 1 xfailed in 10.39 seconds
  >>> result
  True
