def add_test_name_suffix(name, suffix): (source)

Undocumented

Parameters
name:`str`	Undocumented
suffix:`str`	Undocumented
Returns
`str`	Undocumented

def collapse_line_continuation(l): (source)

Undocumented

Parameters
l:`List[str]`	Undocumented
Returns
`List[str]`	Undocumented

def expand_errors(input, output, fnam): (source)

Transform comments such as '# E: message' or '# E:3: message' in input.

The result is lines like 'fnam:line: error: message'.

Parameters
input:`List[str]`	Undocumented
output:`List[str]`	Undocumented
fnam:`str`	Undocumented

def expand_variables(s): (source)

Undocumented

Parameters
s:`str`	Undocumented
Returns
`str`	Undocumented

def fix_cobertura_filename(line): (source)

Changes filename paths to Linux paths in Cobertura output files.

E.g. filename="pkgsubpkga.py" -> filename="pkg/subpkg/a.py".

Parameters
line:`str`	Undocumented
Returns
`str`	Undocumented

def fix_win_path(line): (source)

Changes Windows paths to Linux paths in error messages.

E.g. foobar.py -> foo/bar.py.

Parameters
line:`str`	Undocumented
Returns
`str`	Undocumented

def has_stable_flags(testcase): (source)

Undocumented

Parameters
testcase:`DataDrivenTestCase`	Undocumented
Returns
`bool`	Undocumented

def is_incremental(testcase): (source)

Undocumented

Parameters
testcase:`DataDrivenTestCase`	Undocumented
Returns
`bool`	Undocumented

def module_from_path(path): (source)

Undocumented

Parameters
path:`str`	Undocumented
Returns
`str`	Undocumented

def parse_test_case(case): (source)

Parse and prepare a single case from suite with test case descriptions.

This method is part of the setup phase, just before the test case is run.

Parameters
case:`DataDrivenTestCase`	Undocumented

def parse_test_data(raw_data, name): (source)

Parse a list of lines that represent a sequence of test items.

Parameters
raw_data:`str`	Undocumented
name:`str`	Undocumented
Returns
`List[TestItem]`	Undocumented

def pytest_addoption(parser): (source)

Undocumented

Parameters
parser:`Any`	Undocumented

def pytest_pycollect_makeitem(collector, name, obj): (source)

Called by pytest on each object in modules configured in conftest.py files.

collector is pytest.Collector, returns Optional[pytest.Class]

Parameters
collector:`Any`	Undocumented
name:`str`	Undocumented
obj:`object`	Undocumented
Returns
`Optional[Any]`	Undocumented

def split_test_cases(parent, suite, file): (source)

Iterate over raw test cases in file, at collection time, ignoring sub items.

The collection phase is slow, so any heavy processing should be deferred to after uninteresting tests are filtered (when using -k PATTERN switch).

Parameters
parent:`DataFileCollector`	Undocumented
suite:`DataSuite`	Undocumented
file:`str`	Undocumented
Returns
`Iterator[DataDrivenTestCase]`	Undocumented

def strip_list(l): (source)

Return a stripped copy of l.

Strip whitespace at the end of all lines, and strip all empty lines from the end of the array.

Parameters
l:`List[str]`	Undocumented
Returns
`List[str]`	Undocumented
