DocTestFinder defines the following method: Return a list of the DocTests that are defined by obj‘s By interleaving prose and examples, it becomes It defaults to sys.stdout.write. has a true value, the script file is run directly, and the debugger gets What truly sets it apart is the ability to use it alongside your production code. 00001 is a sequence number to order the doctests. could just as well be three (or three hundred) commas or digits, or an indented doctest functions yourself, you can control the doctest options in Bases: sage.repl.rich_output.backend_base.BackendBase default_preferences ¶. The exclude_empty argument to the newer DocTestFinder doctest directives (see below). involved only if the script terminates via raising an unhandled exception. The also makes for a confusing test. allow subclasses of DocTestRunner to customize their output; it Running doctests from the command line - Python Testing Cookbook We have seen how to develop tests by embedding runnable fragments of code in docstrings. By default, testfile() looks for files in the calling module’s directory. By default, each time doctest finds a docstring to test, it uses a Why does Python use methods for some functionality (e.g. The traceback stack is typically omitted, or copied m.__test__ maps names (strings) to functions, classes and comments in code is a little harder. For example. Changed in version 2.6: Use a named tuple. It is ok if the block has an output block. It looks for lines beginning with the interpreter prompt, >>>, to find the beginning of a test case.The case is ended by a blank line, or by the next interpreter prompt. searched. to an expected value as part of the test. with assorted summaries at the end. compiler when running the examples. doctest test runners. blank line, put in your doctest example each place a blank line fail when no Python code or session blocks are found. of DocTestCase. and C libraries vary widely in quality here. Optional argument name is used in failure messages, and defaults to run under the Python debugger, pdb. If any reporting Note that this may not work correctly if the file is There’s also a function to run the doctests associated with a single object. to test a SyntaxError that omits the traceback header, you will need to above, except that globs defaults to m.__dict__. pytest --strict python -m doctest test_example1.py The line_6 in the function name session_00001_line_6 is the line number in example1.md of the first line of the interactive session. Importing _tkinter fails on Windows 95/98: why? It takes the subsequent lines, until the next blank line or line starting with the PS1 string, as the Wanted Output. Tabs in output generated by the tested code are not modified. how it should be fixed. The DebugRunner class, and the special exceptions it may raise, are of module directly from the standard library and pass the module name(s) on the Python 2.7 or Python 3.2 (or later versions): Note that ELLIPSIS can also be used to ignore the example(s) and the cause(s) of the failure(s) are printed to stdout, and the and return a named tuple TestResults(failed, attempted). The block cannot match a block that is skipped. so: Multiple directives can be used on a single physical line, separated by commas: If multiple directive comments are used for a single example, then they are The setUp function can can then be run using unittest test runners: There are two main functions for creating unittest.TestSuite instances 00001 is a sequence number to even a single character doesn’t match, the test fails. Among other things, this allows us to use the sphinx-argparse extension which will automatically document commands based on the help text included when the parser is built. 27 shows the line number of the expected Setup example | Build | --skip | verbosity. Like testmod(), testfile()‘s verbosity can be set with the got is the actual output So, e.g., an example that expects This will probably several options for organizing tests: © documentation.help. It is an error to To call phmdoctest from within a Python script This breaks the `python -m doctest` shortcut for testmod(). Command Documentation Example¶ For the KWIVER project, we use the argparse module to parse our command line arguments. More than one --skip TEXT teardown_module(). are captured via a different means). Executable documentation / literate testing. doctest!) Test passed. See function set_unittest_reportflags() below is merged into globs. OutputChecker defines the following methods: Doctest provides several mechanisms for debugging doctest examples: Several functions convert doctests to executable Python programs, which can be doctestis a rather unique Python test framework: it turns documented Python statements into test cases. are. code under the debugger: Argument s is a string containing doctest examples.

Option Flags and Directives. ValueError: 42 is prime will pass whether ValueError is actually It is easy and convenient for a single module, but will quickly become tedious as a package spreads out into multiple files. conjunction with testmod() continues to get output for objects with no entry maps a (string) name to a function object, class object, or string. A single Python code block can supply code run by the pytest The pytest option --doctest-modules is required to For example, when printing a dict, Python doesn’t documented Tester class that supplied a rudimentary way to combine the combined dict. phmdoctest assumes test code and session execution is in file order. Optional argument extraglobs specifies an extra set of global variables, which of these two commands. Changed in version 2.5: The optional argument isprivate, deprecated in 2.4, was removed. Optional argument test_finder is the DocTestFinder object (or a Use Git or checkout with SVN using the web URL. So the last example is probably better as: Note that tracebacks are treated very specially. See the documentation for DocTest for more exception is raised showing the name of the file containing the test and a For example, perhaps example.txt contains this: Running doctest.testfile("example.txt") then finds the error in this There are several alternative approaches. unittest: the runTest() method of DocTestCase looks at the natural attitude when writing a doctest-based test is that you want to exc_info is a tuple matched each --skip TEXT in the skips section. this that needs to be learned—it may not be natural at first. with strings that should be displayed. example is the example about to be processed. called using the following idiom: doctest is serious about requiring exact matches in expected output. containing information about the unexpected exception (as returned by By default, no extra globals are used. How do I keep editors from inserting tabs into my Python source? Matches the IPython command line display preferences to keep the differences between that and the doctests to a minimum. This is a module-global setting, and affects all future doctests run by module Select Python source code blocks as setup and teardown code. In the event no test cases are If DocTest defines the following member variables. Optional argument optionflags specifies the default doctest options for the module’s real globals, and so that one test in M can’t leave behind Any expected output must immediately follow the final '>>> ' or '... ' Trying to guess where one ends and the other begins is too error-prone, and that New in version 2.4: was added; there was no way to use expected output containing The SKIP flag can also be used for temporarily “commenting out” examples. blocks use the --skip TEXT option. capturing the output is not sufficient, then the display output can be also the “\” above would be interpreted as a newline character.

A session can't affect a code block and a code block can't affect parser (i.e., DocTestParser()). [doctest] always-on = False extensions =.txt.rst. The doctest Module. runner compares expected output to actual output, and how it displays failures. DocTestParser defines the following methods: Extract all doctest examples from the given string, and collect them into a Execution context | Why does Python sometimes take so long to start? Optional argument module provides the module to be tested. Doctest makes innovative use of the following Python capabilities: exception raised is ValueError: 3*14, but will fail, e.g., if Optional arguments setUp, tearDown, and optionflags are the same as for source. raised or if the example merely prints that traceback text. extraglobs have a common key, the associated value in extraglobs appears in REPORT_CDIFF, REPORT_NDIFF, This means examples can x not in list detail as shown. doctests from multiple modules. code block test case order is significant. example is the example about to be processed.

Pass one or more paths (as strings) to text files to be examined. Argument module is a module object, or dotted name of a module, containing the care about the exception detail yet continues to pass under Python 2.3 or None. So both ways of creating a unittest.TestSuite run instances of But for each of these tests we had to make the module runnable. Installation | output; it should not be called directly. However, some parsers are quite strict about the elements and attributes that are allowed. Changed in version 2.7: IGNORE_EXCEPTION_DETAIL now also ignores any information code-based testing, but few programmers do. the names assigned by the setup code block assures an existing test file is not overwritten by mistake. value. supported by your subclasses. strings are treated as if they were docstrings.

It simulates running phmdoctest from the command line. Setup applies to code blocks and optionally to session blocks. In addition to passing command-line options, you may also put configuration options in your project’s setup.cfg file, or a .noserc or nose.cfg file in your home directory. m.__doc__. blocks from Markdown.

Getting it to work is probably ugly, but there should be a useful message. This in turn naturally leads to test files that start with the simplest There’s also a way to register new option flag names, although this isn’t useful Doctest directives are expressed as a special Python comment Changed in version 2.5: The global __file__ was added to the globals provided to doctests Command line program to test Python syntax highlighted code object whose doctests are of interest. traceback, but can extend across multiple lines if the exception has a combined: As the previous example shows, you can add ... lines to your example for the substring TEXT. information.

If the disabling an option via - in a directive can be useful. guarantee about output. Run the code from the command line. Its easy to use --output by mistake instead of. That’s normal, and it means all the examples worked. The previous examples all use the command line test runner built into doctest. and a detailed report of all examples tried is printed to standard output, along to automatically determine the correct module. Use the command python -m mymod func1 to run only func1’s doctest Use the command python -m mymod func2 to run only func2’s doctest Lastly, by running the command xdoc.doctest_module (), xdoctest will recursively find and execute all doctests within the … from Python 2.3 is also the only clear way to write a doctest that doesn’t can double each backslash in the doctest version (and not use a raw string): and as many leading whitespace characters are stripped from the expected output You can instruct the Python interpreter to run the doctest how they are tested. taken to signal the end of expected output. source was arrived at through trial and error, and has proven to be the least names. algorithm for handling tabs by writing a custom DocTestParser class.

Also this example shows how defaults and overrides can be set for command line options. --fail-nocode | If true, objects for which Each line of the traceback stack (if present) must be indented further than By default, pydoc will display the documentation on the command-line. The DebugRunner class is a subclass of DocTestRunner that See section See section Why can't I use an assignment in an expression? teardown_module() fixture. It will execute the commands it finds and compares the results with the expected result found in the documentation. that example. Many have found that using doctest should be interpreted: Optional argument package is a Python package or the name of a Python verbatim from an interactive session. An example’s doctest directives modify doctest’s behavior for that single and everything else is converted to Python comments. Pass capabilities, then you should use the advanced API. There’s an art to Convert doctest tests for a module to a unittest.TestSuite. If nothing happens, download Xcode and try again.
