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. sreStructuredText entregister_optionflagtDONT_ACCEPT_TRUE_FOR_1tDONT_ACCEPT_BLANKLINEtNORMALIZE_WHITESPACEtELLIPSIStSKIPtIGNORE_EXCEPTION_DETAILtCOMPARISON_FLAGSt REPORT_UDIFFt REPORT_CDIFFt REPORT_NDIFFtREPORT_ONLY_FIRST_FAILUREtREPORTING_FLAGStExampletDocTestt DocTestParsert DocTestFindert DocTestRunnert OutputCheckertDocTestFailuretUnexpectedExceptiont DebugRunnerttestmodttestfiletrun_docstring_examplestTestert DocTestSuitet DocFileSuitetset_unittest_reportflagstscript_from_examplest testsourcet debug_srctdebugiN(tStringIO(t namedtuplet TestResultssfailed attemptedcCstj|dtt>S(Ni(tOPTIONFLAGS_BY_NAMEt setdefaulttlen(tname((s/usr/lib64/python2.7/doctest.pyRss s...cCsUd}xHtjD]=}|j|d}|tt|kr||jO}qqW|S(s Return the compiler-flags associated with the future features that have been imported into the given namespace (globs). iN(t __future__tall_feature_namestgettNonetgetattrt compiler_flag(tglobstflagstfnametfeature((s/usr/lib64/python2.7/doctest.pyt_extract_future_flagss icCs{tj|r|St|ttfrDt|ttdgS|dkrkt j t j |j dSt ddS(s Return the module specified by `module`.

This comparison may be customized with a number of option flags; see the documentation for `testmod` for more information. If the option flags are insufficient, then the comparison may also be customized by passing a subclass of `OutputChecker` to the constructor. The test runner's display output can be controlled in two ways. First, an output function (`out) can be passed to `TestRunner.run`; this function will be called with strings that should be displayed. It defaults to `sys.stdout.write`. If capturing the output is not sufficient, then the display output can be also customized by subclassing DocTestRunner, and overriding the methods `report_start`, `report_success`, `report_unexpected_exception`, and `report_failure`.

Also test examples reachable from dict m.__test__ if it exists and is not None. m.__test__ maps names to functions, classes and strings; function and class docstrings are tested even if the name is private; strings are tested directly, as if they were docstrings. Return (#failures, #tests). See help(doctest) for an overview. Optional keyword arg "name" gives the name of the module; by default use m.__name__. Optional keyword arg "globs" gives a dict to be used as the globals when executing examples; by default, use m.__dict__. A copy of this dict is actually used for each docstring, so that each docstring's examples start with a clean slate. Optional keyword arg "extraglobs" gives a dictionary that should be merged into the globals that are used to execute examples. By default, no extra globals are used. This is new in 2.4. Optional keyword arg "verbose" prints lots of stuff if true, prints only failures if false; by default, it's true iff "-v" is in sys.argv. Optional keyword arg "report" prints a summary at the end when true, else prints nothing at the end. In verbose mode, the summary is detailed, else very brief (in fact, empty if all tests passed). Optional keyword arg "optionflags" or's together module constants, and defaults to 0. This is new in 2.3. Possible values (see the docs for details): DONT_ACCEPT_TRUE_FOR_1 DONT_ACCEPT_BLANKLINE NORMALIZE_WHITESPACE ELLIPSIS SKIP IGNORE_EXCEPTION_DETAIL REPORT_UDIFF REPORT_CDIFF REPORT_NDIFF REPORT_ONLY_FIRST_FAILURE Optional keyword arg "raise_on_error" raises an exception on the first unexpected exception or failure. This allows failures to be post-mortem debugged. Advanced tomfoolery: testmod runs methods of a local instance of class doctest.Tester, then merges the results into (or creates) global Tester instance doctest.master. Methods of doctest.master can be called directly too, if you want to do something unusual. Passing report=0 to testmod is especially useful then, to delay displaying a summary. Invoke doctest.master.summarize(verbose) when you're done fiddling.

This converts each documentation string in a module that contains doctest tests to a unittest test case. If any of the tests in a doc string fail, then the test case fails. An exception is raised showing the name of the file containing the test and a (sometimes approximate) line number. The `module` argument provides the module to be tested. The argument can be either a module or a module name. If no argument is given, the calling module is used. A number of options may be provided as keyword arguments: 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.
