Nose test runner.

This class is made available as numpy.testing.Tester, and a test function

Attributes

----------
|

|
Full path to the package to test.

Parameters
|
|
----------

package : module, str or None, optional

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

|
|
raise_warnings : None, str or sequence of warnings, optional

This specifies which warnings to configure as 'raise' instead
|

|
|
|
- "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

special values. Special values are:

Timing of individual tests with ``nose-timer`` (which needs to be

If an integer (say ``N``), report timing results for ``N`` slowest
