In simplest use, end each module M to be tested with:
def _test():
import doctest
doctest.testmod()
if __name__ == "__main__":
_test()
Then running the module as a script will cause the examples in the
docstrings to get executed and verified:
python M.py
This won't display anything unless an example fails, in which case the
failing example(s) and the cause(s) of the failure(s) are printed to stdout
(why not stderr? because stderr is a lame hack <0.2 wink>), and the final
line of output is "Test failed.".
Run it with the -v switch instead:
python M.py -v
and a detailed report of all examples tried is printed to stdout, along
with assorted summaries at the end.
You can force verbose mode by passing "verbose=True" to testmod, or prohibit
it by passing "verbose=False". In either of those cases, sys.argv is not
examined by testmod.
There are a variety of other ways to run doctests, including integration
with the unittest framework, and support for running non-Python text
files containing doctests. There are also many ways to override parts
of doctest's default behaviors. See the Library Reference Manual for
details.

A single doctest example, consisting of source code and expected
output. `Example` defines the following attributes:
- source: A single Python statement, always ending with a newline.
The constructor adds a newline if needed.
- want: The expected output from running the source code (either
from stdout, or a traceback in case of exception). `want` ends
with a newline unless it's empty, in which case it's an empty
string. The constructor adds a newline if needed.
- exc_msg: The exception message generated by the example, if
the example is expected to generate an exception; or `None` if
it is not expected to generate an exception. This exception
message is compared against the return value of
`traceback.format_exception_only()`. `exc_msg` ends with a
newline unless it's `None`. The constructor adds a newline
if needed.
- lineno: The line number within the DocTest string containing
this Example where the Example begins. This line number is
zero-based, with respect to the beginning of the DocTest.
- indent: The example's indentation in the DocTest string.
I.e., the number of space characters that preceed the
example's first prompt.
- options: A dictionary mapping from option flags to True or
False, which is used to override default options for this
example. Any option flags not contained in this dictionary
are left at their default value (as specified by the
DocTestRunner's optionflags). By default, no options are set.

A collection of doctest examples that should be run in a single
namespace. Each `DocTest` defines the following attributes:
- examples: the list of examples.
- globs: The namespace (aka globals) that the examples should
be run in.
- name: A name identifying the DocTest (typically, the name of
the object whose docstring this DocTest was extracted from).
- filename: The name of the file that this DocTest was extracted
from, or `None` if the filename is unknown.
- lineno: The line number within filename where this DocTest
begins, or `None` if the line number is unavailable. This
line number is zero-based, with respect to the beginning of
the file.
- docstring: The string that the examples were extracted from,
or `None` if the string is unavailable.

Optional keyword arg `checker` is the `OutputChecker` that
should be used to compare the expected outputs and actual
outputs of doctest examples.
Optional keyword arg 'verbose' prints lots of stuff if true,
only failures if false; by default, it's true iff '-v' is in
sys.argv.
Optional argument `optionflags` can be used to control how the
test runner compares expected output to actual output, and how
it displays failures. See the documentation for `testmod` for

Run the examples in `test`, and display the results using the
writer function `out`.
The examples are run in the namespace `test.globs`. If
`clear_globs` is true (the default), then this namespace will
be cleared after the test runs, to help with garbage
collection. If you would like to examine the namespace after
the test completes, then use `clear_globs=False`.
`compileflags` gives the set of flags that should be used by
the Python compiler when running the examples. If not
specified, then it will default to the set of future-import
flags that apply to `globs`.
The output of each example is checked using
`DocTestRunner.check_output`, and the results are formatted by
the `DocTestRunner.report_*` methods.

Print a summary of all the test cases that have been run by
this DocTestRunner, and return a tuple `(f, t)`, where `f` is
the total number of failed examples, and `t` is the total
number of tried examples.
The optional `verbose` argument controls how detailed the
summary is. If the verbosity is not specified, then the
DocTestRunner's verbosity is used.

The path to each doctest file is given as a string; the
interpretation of that string depends on the keyword argument
"module_relative".
A number of options may be provided as keyword arguments:
module_relative
If "module_relative" is True, then the given file paths are
interpreted as os-independent module-relative paths. By
default, these paths are relative to the calling module's
directory; but if the "package" argument is specified, then
they are relative to that package. To ensure os-independence,
"filename" should use "/" characters to separate path
segments, and may not be an absolute path (i.e., it may not
begin with "/").
If "module_relative" is False, then the given file paths are
interpreted as os-specific paths. These paths may be absolute
or relative (to the current working directory).
package
A Python package or the name of a Python package whose directory
should be used as the base directory for module relative paths.
If "package" is not specified, then the calling module's
directory is used as the base directory for module relative
filenames. It is an error to specify "package" if
"module_relative" is False.
setUp
A set-up function. This is called before running the
tests in each file. The setUp function will be passed a DocTest
object. The setUp function can access the test globals as the
globs attribute of the test passed.
tearDown
A tear-down function. This is called after running the
tests in each file. The tearDown function will be passed a DocTest
object. The tearDown function can access the test globals as the
globs attribute of the test passed.
globs
A dictionary containing initial global variables for the tests.
optionflags
A set of doctest option flags expressed as an integer.
parser
A DocTestParser (or subclass) that should be used to extract
tests from the files.
