def add_test_name_suffix(name: str, suffix: str) -> str: (source)

Undocumented

def collapse_line_continuation(l: list[str]) -> list[str]: (source)

Undocumented

def expand_errors(input: list[str], output: list[str], fnam: str): (source)

Transform comments such as '# E: message' or '# E:3: message' in input. The result is lines like 'fnam:line: error: message'.

def expand_variables(s: str) -> str: (source)

Undocumented

def fix_cobertura_filename(line: str) -> str: (source)

Changes filename paths to Linux paths in Cobertura output files. E.g. filename="pkg\subpkg\a.py" -> filename="pkg/subpkg/a.py".

def fix_win_path(line: str) -> str: (source)

Changes Windows paths to Linux paths in error messages. E.g. foo\bar.py -> foo/bar.py.

def has_stable_flags(testcase: DataDrivenTestCase) -> bool: (source)

Undocumented

def is_incremental(testcase: DataDrivenTestCase) -> bool: (source)

Undocumented

def module_from_path(path: str) -> str: (source)

Undocumented

def parse_test_case(case: DataDrivenTestCase): (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.

def parse_test_data(raw_data: str, name: str) -> list[TestItem]: (source)

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

def pytest_addoption(parser: Any): (source)

Undocumented

def pytest_pycollect_makeitem(collector: Any, name: str, obj: object) -> Any|None: (source)

Called by pytest on each object in modules configured in conftest.py files. collector is pytest.Collector, returns Optional[pytest.Class]

def split_test_cases(parent: DataFileCollector, suite: DataSuite, file: str) -> Iterator[DataDrivenTestCase]: (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).

def strip_list(l: list[str]) -> list[str]: (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.
