twisted.trial.runner

A miscellany of code used to run Trial tests.

Maintainer: Jonathan Lange

Function	isPackage	Given an object return True if the object looks like a package
Function	isPackageDirectory	Is the directory at path 'dirname' a Python package directory? Returns the name of the __init__ file (it may have a weird extension) if dirname is a package directory. Otherwise, returns False
Function	samefile	A hacky implementation of `os.path.samefile`. Used by `filenameToModule` when the platform doesn't provide `os.path.samefile`. Do not use this.
Function	filenameToModule	Given a filename, do whatever possible to return a module object matching that file.
Class	DestructiveTestSuite	A test suite which remove the tests once run, to minimize memory usage.
Class	LoggedSuite	Any errors logged in this suite will be reported to the `TestResult` object.
Class	TrialSuite	Suite to wrap around every single test in a `trial` run. Used internally by Trial to set up things necessary for Trial tests to work, regardless of what context they are run in.
Function	name
Function	isTestCase
Class	TestHolder	Placeholder for a `TestCase` inside a reporter. As far as a `TestResult` is concerned, this looks exactly like a unit test.
Class	ErrorHolder	No summary
Class	TestLoader	I find tests inside function, modules, files -- whatever -- then return them wrapped inside a Test (either a `TestSuite` or a `TestCase`).
Class	Py3TestLoader	A test loader finds tests from the functions, modules, and files that is asked to and loads them into a `TestSuite` or `TestCase`.
Class	TrialRunner	A specialised runner that the trial front end uses.
Function	_importFromFile	Undocumented
Function	_resolveDirectory	Undocumented
Function	_getMethodNameInClass	Find the attribute name on the method's class which refers to the method.
Function	_qualNameWalker	Given a Python qualified name, this function yields a 2-tuple of the most specific qualified name first, followed by the next-most-specific qualified name, and so on, paired with the remainder of the qualified name.

def isPackage(module):

Given an object return True if the object looks like a package

def isPackageDirectory(dirname):

Is the directory at path 'dirname' a Python package directory? Returns the name of the __init__ file (it may have a weird extension) if dirname is a package directory. Otherwise, returns False

def samefile(filename1, filename2):

A hacky implementation of os.path.samefile. Used by filenameToModule when the platform doesn't provide os.path.samefile. Do not use this.

def filenameToModule(fn):

Given a filename, do whatever possible to return a module object matching that file.

If the file in question is a module in Python path, properly import and return that module. Otherwise, load the source manually.

Parameters	fn	A filename.
Returns	A module object.
Raises	ValueError	If `fn` does not exist.

def _importFromFile(fn, moduleName=None):

Undocumented

def _resolveDirectory(fn):

Undocumented

def _getMethodNameInClass(method):

Find the attribute name on the method's class which refers to the method.

For some methods, notably decorators which have not had __name__ set correctly:

getattr(method.im_class, method.__name__) != method

def name(thing):

Parameters thing an object from modules (instance of PythonModule, PythonAttribute), a TestCase subclass, or an instance of a TestCase.

def isTestCase(obj):

Returns True if obj is a class that contains test cases, False otherwise. Used to find all the tests in a module.

def _qualNameWalker(qualName):

Given a Python qualified name, this function yields a 2-tuple of the most specific qualified name first, followed by the next-most-specific qualified name, and so on, paired with the remainder of the qualified name.

Parameters qualName A Python qualified name. (type: str)
