It is documented here to help Python developers write tests. The API of this module is subject to change without backwards compatibility concerns between releases.\n\nThis module defines the following exceptions\n\nException to be raised when a test fails. This is deprecated in favor of unittest\\ -based tests and unittest.TestCase's assertion methods.\n\nSubclass of unittest.SkipTest. Raised when a resource (such as a network connection) is not available. Raised by the requires function.\n\nThe !test.support module defines the following constants\n\nTrue when verbose output is enabled. Should be checked when more detailed information is desired about a running test. verbose is set by test.regrtest.\n\nTrue if the running interpreter is Jython.\n\nTrue if sys.platform is android.\n\nTrue if sys.platform is emscripten.\n\nTrue if sys.platform is wasi.\n\nTrue if sys.platform is ios, tvos, or watchos.\n\nTrue if sys.platform is darwin or is_apple_mobile is True.\n\nPath for shell if not on Windows; otherwise None.\n\nTimeout in seconds for tests using a network server listening on the network local loopback interface like 127.0.0.1.\n\nThe 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.\n\nThe timeout should be long enough for ~socket.socket.connect, ~socket.socket.recv and ~socket.socket.send methods of socket.socket.\n\nIts default value is 10 seconds.\n\nSee also INTERNET_TIMEOUT.\n\nTimeout in seconds for network requests going to the internet.\n\nThe timeout is short enough to prevent a test to wait for too long if the internet request is blocked for whatever reason.\n\nUsually, a timeout using INTERNET_TIMEOUT should not mark a test as failed, but skip the test instead: see ~test.support.socket_helper.transient_internet.\n\nIts default value is 1 minute.\n\nSee also LOOPBACK_TIMEOUT.\n\nTimeout in seconds to mark a test as failed if the test takes \"too long\".\n\nThe timeout value depends on the regrtest --timeout command line option.\n\nIf a test using SHORT_TIMEOUT starts to fail randomly on slow buildbots, use LONG_TIMEOUT instead.\n\nIts default value is 30 seconds.\n\nTimeout in seconds to detect when a test hangs. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
