Name of the package to test.
Parameters

The package to test. If a string, this should be the full path to
the package. If None (default), `package` is set to the module from
which `NoseTester` is initialized.
raise_warnings : None, str or sequence of warnings, optional

of being shown once during the test execution. Valid strings are:
- "develop" : equals ``(Warning,)``
- "release" : equals ``()``, don't raise on any warnings.
Default is "release".
depth : int, optional
If `package` is None, then this can be used to initialize from the
module of the caller of (the caller of (...)) the code that
initializes `NoseTester`. Default of 0 means the module of the
immediate caller; higher values are useful for utility routines that
want to initialize `NoseTester` objects on behalf of other code.

Run tests for module using nose.
Parameters
----------
label : {'fast', 'full', '', attribute identifier}, optional
Identifies the tests to run. This can be a string to pass to
the nosetests executable with the '-A' option, or one of several
special values. Special values are:
* 'fast' - the default - which corresponds to the ``nosetests -A``
option of 'not slow'.

'no -A' option to nosetests - this is the same as ''.

* attribute_identifier - string passed directly to nosetests as '-A'.
verbose : int, optional

extra_argv : list, optional
List with any extra arguments to pass to nosetests.
doctests : bool, optional
If True, run doctests in module. Default is False.
coverage : bool, optional
If True, report coverage of NumPy code. Default is False.
(This requires the
`coverage module <https://pypi.org/project/coverage/>`_).
raise_warnings : None, str or sequence of warnings, optional
This specifies which warnings to configure as 'raise' instead
of being shown once during the test execution. Valid strings are:
* "develop" : equals ``(Warning,)``
* "release" : equals ``()``, do not raise on any warnings.
timer : bool or int, optional
Timing of individual tests with ``nose-timer`` (which needs to be
installed). If True, time tests and report on all of them.
If an integer (say ``N``), report timing results for ``N`` slowest
tests.
Returns
-------
result : object
Returns the result of running the tests as a
``nose.result.TextTestResult`` object.
Notes
-----
Each NumPy module exposes `test` in its namespace to run all tests for it.
