@test.support.bigaddrspacetest(f) Decorator for tests that fill the address space. f is the function to wrap.
python.library.test#test.support.bigaddrspacetest
@test.support.bigmemtest(size, memuse, dry_run=True) Decorator for bigmem tests. size is a requested size for the test (in arbitrary, test-interpreted units.) memuse is the number of bytes per unit for the test, or a good estimate of it. For example, a test that needs two byte buffers, of 4 GiB each, could be decorated with @bigmemtest(size=_4G, memuse=2). The size argument is normally passed to the decorated test method as an extra argument. If dry_run is True, the value passed to the test method may be less than the requested value. If dry_run is False, it means the test doesn’t support dummy runs when -M is not specified.
python.library.test#test.support.bigmemtest

test.support.catch_threading_exception() Context manager catching threading.Thread exception using threading.excepthook(). Attributes set when an exception is catched: exc_type exc_value exc_traceback thread See threading.excepthook() documentation. These attributes are deleted at the context manager exit. Usage: with support.catch_threading_exception() as cm: # code spawning a thread which raises an exception ... # check the thread exception, use cm attributes: # exc_type, exc_value, exc_traceback, thread ... # exc_type, exc_value, exc_traceback, thread attributes of cm no longer # exists at this point # (to avoid reference cycles) New in version 3.8.
python.library.test#test.support.catch_threading_exception
test.support.catch_unraisable_exception() Context manager catching unraisable exception using sys.unraisablehook(). Storing the exception value (cm.unraisable.exc_value) creates a reference cycle. The reference cycle is broken explicitly when the context manager exits. Storing the object (cm.unraisable.object) can resurrect it if it is set to an object which is being finalized. Exiting the context manager clears the stored object. Usage: with support.catch_unraisable_exception() as cm: # code creating an "unraisable exception" ... # check the unraisable exception: use cm.unraisable ... # cm.unraisable attribute no longer exists at this point # (to break a reference cycle) New in version 3.8.
python.library.test#test.support.catch_unraisable_exception
test.support.change_cwd(path, quiet=False) A context manager that temporarily changes the current working directory to path and yields the directory. If quiet is False, the context manager raises an exception on error. Otherwise, it issues only a warning and keeps the current working directory the same.

python.library.test#test.support.check_impl_detail
test.support.check_no_resource_warning(testcase) Context manager to check that no ResourceWarning was raised. You must remove the object which may emit ResourceWarning before the end of the context manager.
python.library.test#test.support.check_no_resource_warning
test.support.check_syntax_error(testcase, statement, errtext='', *, lineno=None, offset=None) Test for syntax errors in statement by attempting to compile statement. testcase is the unittest instance for the test. errtext is the regular expression which should match the string representation of the raised SyntaxError. If lineno is not None, compares to the line of the exception. If offset is not None, compares to the offset of the exception.
python.library.test#test.support.check_syntax_error
test.support.check_syntax_warning(testcase, statement, errtext='', *, lineno=1, offset=None) Test for syntax warning in statement by attempting to compile statement. Test also that the SyntaxWarning is emitted only once, and that it will be converted to a SyntaxError when turned into error. testcase is the unittest instance for the test. errtext is the regular expression which should match the string representation of the emitted SyntaxWarning and raised SyntaxError. If lineno is not None, compares to the line of the warning and exception. If offset is not None, compares to the offset of the exception. New in version 3.8.
python.library.test#test.support.check_syntax_warning
test.support.check_warnings(*filters, quiet=True) A convenience wrapper for warnings.catch_warnings() that makes it easier to test that a warning was correctly raised. It is approximately equivalent to calling warnings.catch_warnings(record=True) with warnings.simplefilter() set to always and with the option to automatically validate the results that are recorded. check_warnings accepts 2-tuples of the form ("message regexp", WarningCategory) as positional arguments. If one or more filters are provided, or if the optional keyword argument quiet is False, it checks to make sure the warnings are as expected: each specified filter must match at least one of the warnings raised by the enclosed code or the test fails, and if any warnings are raised that do not match any of the specified filters the test fails. To disable the first of these checks, set quiet to True. If no arguments are specified, it defaults to: check_warnings(("", Warning), quiet=True) In this case all warnings are caught and no errors are raised. On entry to the context manager, a WarningRecorder instance is returned. The underlying warnings list from catch_warnings() is available via the recorder object’s warnings attribute. As a convenience, the attributes of the object representing the most recent warning can also be accessed directly through the recorder object (see example below). If no warning has been raised, then any of the attributes that would otherwise be expected on an object representing a warning will return None. The recorder object also has a reset() method, which clears the warnings list. The context manager is designed to be used like this: with check_warnings(("assertion is always true", SyntaxWarning), ("", UserWarning)): exec('assert(False, "Hey!")') warnings.warn(UserWarning("Hide me!")) In this case if either warning was not raised, or some other warning was raised, check_warnings() would raise an error. When a test needs to look more deeply into the warnings, rather than just checking whether or not they occurred, code like this can be used: with check_warnings(quiet=True) as w: warnings.warn("foo") assert str(w.args[0]) == "foo" warnings.warn("bar") assert str(w.args[0]) == "bar" assert str(w.warnings[0].args[0]) == "foo" assert str(w.warnings[1].args[0]) == "bar" w.reset() assert len(w.warnings) == 0 Here all warnings will be caught, and the test code tests the captured warnings directly. Changed in version 3.2: New optional arguments filters and quiet.
python.library.test#test.support.check_warnings
test.support.check__all__(test_case, module, name_of_module=None, extra=(), blacklist=()) Assert that the __all__ variable of module contains all public names. The module’s public names (its API) are detected automatically based on whether they match the public name convention and were defined in module. The name_of_module argument can specify (as a string or tuple thereof) what module(s) an API could be defined in order to be detected as a public API. One case for this is when module imports part of its public API from other modules, possibly a C backend (like csv and its _csv). The extra argument can be a set of names that wouldn’t otherwise be automatically detected as “public”, like objects without a proper __module__ attribute. If provided, it will be added to the automatically detected ones. The blacklist argument can be a set of names that must not be treated as part of the public API even though their names indicate otherwise. Example use: import bar import foo import unittest from test import support class MiscTestCase(unittest.TestCase): def test__all__(self): support.check__all__(self, foo) class OtherTestCase(unittest.TestCase): def test__all__(self): extra = {'BAR_CONST', 'FOO_CONST'} blacklist = {'baz'} # Undocumented name. # bar imports part of its API from _bar. support.check__all__(self, bar, ('bar', '_bar'), extra=extra, blacklist=blacklist) New in version 3.6.
python.library.test#test.support.check__all__
class test.support.CleanImport(*module_names) A context manager to force import to return a new module reference. This is useful for testing module-level behaviors, such as the emission of a DeprecationWarning on import. Example usage: with CleanImport('foo'): importlib.import_module('foo') # New reference.

test.support.detect_api_mismatch(ref_api, other_api, *, ignore=()) Returns the set of attributes, functions or methods of ref_api not found on other_api, except for a defined list of items to be ignored in this check specified in ignore. By default this skips private attributes beginning with ‘_’ but includes all magic methods, i.e. those starting and ending in ‘__’. New in version 3.5.
python.library.test#test.support.detect_api_mismatch
class test.support.DirsOnSysPath(*paths) A context manager to temporarily add directories to sys.path. This makes a copy of sys.path, appends any directories given as positional arguments, then reverts sys.path to the copied settings when the context ends. Note that all sys.path modifications in the body of the context manager, including replacement of the object, will be reverted at the end of the block.
python.library.test#test.support.DirsOnSysPath

python.library.test#test.support.fd_count
test.support.findfile(filename, subdir=None) Return the path to the file named filename. If no match is found filename is returned. This does not equal a failure since it could be the path to the file. Setting subdir indicates a relative path to use to find the file rather than looking directly in the path directories.
python.library.test#test.support.findfile
test.support.forget(module_name) Remove the module named module_name from sys.modules and delete any byte-compiled files of the module.

python.library.test#test.support.impl_detail
test.support.import_fresh_module(name, fresh=(), blocked=(), deprecated=False) This function imports and returns a fresh copy of the named Python module by removing the named module from sys.modules before doing the import. Note that unlike reload(), the original module is not affected by this operation. fresh is an iterable of additional module names that are also removed from the sys.modules cache before doing the import. blocked is an iterable of module names that are replaced with None in the module cache during the import to ensure that attempts to import them raise ImportError. The named module and any modules named in the fresh and blocked parameters are saved before starting the import and then reinserted into sys.modules when the fresh import is complete. Module and package deprecation messages are suppressed during this import if deprecated is True. This function will raise ImportError if the named module cannot be imported. Example use: # Get copies of the warnings module for testing without affecting the # version being used by the rest of the test suite. One copy uses the # C implementation, the other is forced to use the pure Python fallback # implementation py_warnings = import_fresh_module('warnings', blocked=['_warnings']) c_warnings = import_fresh_module('warnings', fresh=['_warnings']) New in version 3.1.
python.library.test#test.support.import_fresh_module
test.support.import_module(name, deprecated=False, *, required_on()) This function imports and returns the named module. Unlike a normal import, this function raises unittest.SkipTest if the module cannot be imported. Module and package deprecation messages are suppressed during this import if deprecated is True. If a module is required on a platform but optional for others, set required_on to an iterable of platform prefixes which will be compared against sys.platform. New in version 3.1.
python.library.test#test.support.import_module
test.support.INTERNET_TIMEOUT Timeout in seconds for network requests going to the Internet. The timeout is short enough to prevent a test to wait for too long if the Internet request is blocked for whatever reason. Usually, a timeout using INTERNET_TIMEOUT should not mark a test as failed, but skip the test instead: see transient_internet(). Its default value is 1 minute. See also LOOPBACK_TIMEOUT.

In simple cases, the test package’s __init__.py can be the following: import os from test.support import load_package_tests def load_tests(*args): return load_package_tests(os.path.dirname(__file__), *args)
python.library.test#test.support.load_package_tests
test.support.LONG_TIMEOUT Timeout in seconds to detect when a test hangs. It is long enough to reduce the risk of test failure on the slowest Python buildbots. It should not be used to mark a test as failed if the test takes “too long”. The timeout value depends on the regrtest --timeout command line option. Its default value is 5 minutes. See also LOOPBACK_TIMEOUT, INTERNET_TIMEOUT and SHORT_TIMEOUT.
python.library.test#test.support.LONG_TIMEOUT
test.support.LOOPBACK_TIMEOUT Timeout in seconds for tests using a network server listening on the network local loopback interface like 127.0.0.1. The timeout is long enough to prevent test failure: it takes into account that the client and the server can run in different threads or even different processes. The timeout should be long enough for connect(), recv() and send() methods of socket.socket. Its default value is 5 seconds. See also INTERNET_TIMEOUT.
python.library.test#test.support.LOOPBACK_TIMEOUT
