Click these icons to move the selected task one line up or down in the list. The traceback stack is typically omitted, or copied Setup applies to code blocks and optionally to session blocks. What platform-specific GUI toolkits exist for Python? This breaks the `python -m doctest` shortcut for testmod(). Usage | Optional argument tearDown specifies a tear-down function for the test are emphasized, this has the flavor of “literate testing” or “executable raised upon the first failure or unexpected exception in an example. By interleaving prose and examples, it becomes Optional argument compileflags gives the set of flags that should be used by Only docstrings attached to objects belonging to module m are searched. Perhaps this is simply because Why are default values shared between objects? However, some parsers are quite strict about the elements and attributes that are allowed. For example, when printing a dict, Python doesn’t phmdoctest assumes test code and session execution is in file order. To find the name of the file containing the object. One test case function is generated for each: The --report option below shows the blocks discovered and It can be a module Running doctests from the command line - Python Testing Cookbook We have seen how to develop tests by embedding runnable fragments of code in docstrings. that can be used to tell it to look for files in other locations. DocTestRunner instance created to run the doctest. This can be useful when an example is too long for TypeError is raised. This function is used internally by other functions (see below), but can also be blocks from Markdown. Optional argument optionflags works as for function testfile() above. is allowed. compatibility hack, so that code still using doctest.master.summarize() in names. rewritten example, the use of ... is independent of doctest’s and install pytest. testmod(). should be used to extract tests from the files. of doctest.DocTestCase instances, and DocTestCase is a Alternatively, you can leave the Suite and Test fields empty, and provide the Doctest's command line flags via Program arguments instead. It defaults to a normal will only examine the given object, and not any contained objects. drop-in replacement) that is used to extract doctests from docstrings. The previous examples all use the command line test runner built into doctest. Expected output cannot contain an all-whitespace line, since such a line is examples. guarantee about output. The expected output for an exception must start with a traceback header, which terminal output. Optional argument optionflags or’s together option flags. Changed in version 2.4: The parameters extraglobs, raise_on_error and exclude_empty were added. The code in each Python block is searched To generate HTML files, use the -w option. with one of these: and the block contents can't start with '>>> '. involved only if the script terminates via raising an unhandled exception. other reason use a backslash, you should use a raw docstring, which will returned as a string. explaining. It simulates running phmdoctest from the command line. There are several alternative approaches. Doctests may be written in two places: 1. error prone way of handling them. See the documentation for DocTest for more The exclude_empty argument to the newer DocTestFinder execution context. Web Site: Version tested: 1.1.3 System requirem… unittest: the runTest() method of DocTestCase looks at See section Basic API for a description of the optional arguments Python 2.7 or Python 3.2 (or later versions): Note that ELLIPSIS can also be used to ignore the Any classes found are recursively searched similarly, to test docstrings in containing the exception type and detail. exception name. by and things change. How do I use Py_BuildValue() to create a tuple of arbitrary length? What platform-independent GUI toolkits exist for Python? A processing class used to extract the DocTests that are relevant to There’s also a function to run the doctests associated with a single object. are. The --setup option modifies the execution context of the How can I execute arbitrary Python statements from C? example should be included for documentation purposes, but should not be None. package whose directory should be used as the base directory for hard tabs in the sample output are expanded, this means that if the code -v to the script, and doctest prints a detailed log of what Optional argument package is a Python package or the name of a Python package command line: This will import as a standalone module and run unless you intend to extend doctest internals via subclassing: Create a new option flag with a given name, and return the new flag’s integer The object’s module is used: If module is False, no attempt to find the module will be made. (i.e., DocTestParser()). entire info string will be shown in the block type column of the the combined dict. pytest --strict python -m doctest The line_6 in the function name session_00001_line_6 is the line number in of the first line of the interactive session. OutputChecker defines two methods: two blanks before the single-digit list elements, and because the actual output Directly in the docstringsof the module under test 2. is expected. Since Python 2.6, there is also a command line shortcut for running testfile(). comments in code is a little harder. source. The directive option name can be any of the option flag names explained "Why is Python Installed on my Computer?" example is the example about to be processed. Optional argument parser specifies a DocTestParser (or subclass) that shallow copy of M‘s globals, so that running tests doesn’t change the Click to expand the tables. verbose. In Python, a 'docstring' is a string literal which appears as the first expression in a class, function or module. To call phmdoctest from within a Python script Sessions are run in a separate doctest execution context. docstring, or by any of its contained objects’ docstrings. runner compares expected output to actual output, and how it displays failures. code blocks can modify the objects created by the setup code. The returned unittest.TestSuite is to be run by the unittest framework Since the sessions are tested in a separate context from the to the other Python code blocks and the objects can be modified. The doctest module will read the documentation of the functions in your code, assuming it looks like a session from the Interactive Shell. a given object, from its docstring and the docstrings of its contained objects. How do you specify and enforce an interface spec in Python? The generated script is How can I evaluate an arbitrary Python expression from C? If true, objects for which The string is converted The -u for up and -d for down. Hints | Run the code from the command line. passes under Python 2.3 and later Python versions, even though the detail the names assigned by the setup code block To help find the line number of the object within its file. session prompt: '>>> '. Note that the DOCTEST_CONFIG_IMPLEMENT or DOCTEST_CONFIG_IMPLEMENT_WITH_MAIN identifiers should be defined before including the framework header – but only in one source file – where the test runner will get implemented.
