|
|
asynchronous code.
|
|
|
|
The unittest framework is synchronous, so the test must be
|
|
complete by the time the test method returns. This means that
|
|
asynchronous code cannot be used in quite the same way as usual.
|
|
To write test functions that use the same ``yield``-based patterns
|
|
used with the `tornado.gen` module, decorate your test methods
|
|
with `tornado.testing.gen_test` instead of
|
|
`tornado.gen.coroutine`. This class also provides the `stop()`
|
|
and `wait()` methods for a more manual style of testing. The test
|
|
method itself must call ``self.wait()``, and asynchronous
|
|
callbacks should call ``self.stop()`` to signal completion.
|
|
|
|
By default, a new `.IOLoop` is constructed for each test and is available
|
|
as ``self.io_loop``. This `.IOLoop` should be used in the construction of
|
|
HTTP clients/servers, etc. If the code being tested requires a
|
|
global `.IOLoop`, subclasses should override `get_new_ioloop` to return it.
|
|
|
|
The `.IOLoop`'s ``start`` and ``stop`` methods should not be
|
|
called directly. Instead, use `self.stop <stop>` and `self.wait
|
|
<wait>`. Arguments passed to ``self.stop`` are returned from
|
|
``self.wait``. It is possible to have multiple ``wait``/``stop``
|
|
cycles in the same test.

Some libraries can produce a lot of logging output even when

`tornado.options`. It is not compatible with other log buffering

mechanisms, such as those provided by some test runners.

This test runner is essentially equivalent to `unittest.main` from
|

the standard library, but adds support for tornado-style option
|
|
parsing and log formatting.
|
|
|
|
The easiest way to run a test is via the command line::
|
|
|
|
python -m tornado.testing tornado.test.stack_context_test
|
|
|
|
See the standard library unittest module for ways in which tests can
|
|
be specified.
|
|
|
|
Projects with many tests may wish to define a test script like
|
|
``tornado/test/runtests.py``. This script should define a method
|
|
``all()`` which returns a test suite and then call
|
|
`tornado.testing.main()`. Note that even when a test script is
|
|
used, the ``all()`` test suite may be overridden by naming a
|
|
single test on the command line::
|
|
|
|
# Runs all tests
|
|
python -m tornado.test.runtests
|
|
# Runs one test
|
|
python -m tornado.test.runtests tornado.test.stack_context_test
|
|
|
|
Additional keyword arguments passed through to ``unittest.main()``.
|
|
For example, use ``tornado.testing.main(verbosity=2)``
|
|
to show many test details as they are run.
|
|
See http://docs.python.org/library/unittest.html#unittest.main
|
|
for full argument list.
