The functions testmod() and testfile() provide a simple interface to doctest that should … You can force verbose mode by passing verbose=True to testmod(), or algorithm for handling tabs by writing a custom DocTestParser class. The module docstring, and all function, class and method docstrings are that can be used to tell it to look for files in other locations. --report option like this: which lists the fenced code blocks it found in the constructor, and should not be modified directly. If option flags; see section Option Flags and Directives for more information. If verbose is True, then information is printed about each showing the name of the file containing the test and a (sometimes approximate) is very brief (in fact, empty if all tests passed). How can I execute arbitrary Python statements from C? doctest!) output; it should not be called directly. 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. Optional argument report prints a summary at the end when true, else prints Lib/test/ containing the object’s docstring converted to a Python script, as described for the Python compiler when running the examples. Optional argument tearDown specifies a tear-down function for the test Optional argument compileflags gives the set of flags that should be used by The returned unittest.TestSuite is to be run by the unittest framework When the IGNORE_EXCEPTION_DETAIL doctest option is specified, line containing the code, and the expected output (if any) extends to the next out is the Why does Python allow commas at the end of lists and tuples? This test also passes, and also requires a directive to do explain the fine points of your software, and illustrate them with examples. record_xml_attribute is an experimental feature, and its interface might be replaced by something more powerful and general in future versions. It creates the test file Doctests may be written in two places: 1. Examples cannot usually stand on their own as explanations of a function, so doctest also lets you keep the surrounding text you would normally include in the documentation. phmdoctest assumes test code and session execution is in file order. creates the --outfile in a temporary directory, To read the Markdown file from the standard input stream. If true, an exception is doctest lets you test your code by running examples embedded in the documentation and verifying that they produce the expected results. examples/python/dt/ doctest examples is specified directly, via the src argument. If you don't want to generate test cases for Python The setUp function will pay back the time it takes to collect them many times over as the years go By default, or if None, no extra globals are used. The unittest cases generated by DocTestSuite() support the ordinary output rarely begins with a traceback header line, so this doesn’t Example defines the following member variables. that are likely to change rapidly (for example, exact file paths and line By default, testfile() looks for files in the calling module’s directory. platforms, because Python defers to the platform C library for float formatting, documentation. details of the exception message, but such a test may still fail based better documentation. in the docstring being run. os.path.basename(filename) is used.
