Several module level functions are available for controlling how doctests are run.
-
- Debug a single docstring containing doctests.
Provide the module (or dotted name of the module) containing the docstring
to be debugged and the name (within the module) of the object with the
docstring to be debugged.
The doctest examples are extracted (see function testsource()),
and written to a temporary file. The Python debugger, pdb, is then invoked on that file. New in version 2.3.
-
- This function provides the most basic interface to the doctests. It creates a local
instance of class Tester, runs appropriate methods of that class,
and merges the results into the global Tester instance,
master.
To get finer control than testmod() offers, create an
instance of Tester with custom policies, or run methods of master
directly. See Tester.__doc__ for details.

- Extract the doctest examples from a docstring.
Provide the module (or dotted name of the module) containing the tests to be
extracted and the name (within the module) of the object with the docstring
containing the tests to be extracted.
The doctest examples are returned as a string containing Python code. The expected
output blocks in the examples are converted to Python comments. New
in version 2.3.
-
- Convert doctest tests for a module to a unittest.TestSuite.
The returned TestSuite is to be run by the unittest framework
and runs each doctest in the module. If any of the doctests fail, then the synthesized
unit test fails, and a DocTestTestFailure exception is raised
showing the name of the file containing the test and a (sometimes approximate) line
number.
The optional module argument provides the module to be tested. It can be a
module object or a (possibly dotted) module name. If not specified, the module calling
this function is used.
Example using one of the many ways that the unittest module can use a TestSuite:
import unittest
import doctest
import my_module_with_doctests
suite = doctest.DocTestSuite(my_module_with_doctests)
runner = unittest.TextTestRunner()
runner.run(suite)
New in version 2.3. Warning: This function does not currently search M.__test__
and its search technique does not exactly match testmod() in
every detail. Future versions will bring the two into convergence.
