运行试验#
GEvent有一个广泛的回归测试套件，使用标准实现 unittest 模块。它使用 custom testrunner 它提供了增强的测试隔离（对猴子补丁很重要），并行运行测试，并处理其他特定于GEvent的异常。
备注
gevent测试过程运行Python标准库测试，并应用gevent的monkey补丁，以确保gevent行为正确（与标准库匹配）。标准库 test 必须可用才能执行此操作。
这种情况通常是自动发生的，但有些发行版会删除此模块。值得注意的是，在Debian上，您可能需要 libpythonX.Y-testsuite 已安装以运行所有测试。
测试运行程序有许多选项：
$ python -mgevent.tests --help
usage: __main__.py [-h] [--ignore IGNORE] [--discover] [--config CONFIG]
[--coverage] [--quiet] [--verbose] [--debug]
[--package PACKAGE] [--processes PROCESSES] [--no-combine]
[-u RES1,RES2,...] [--travis-fold MSG]
[--second-chance | --failfast]
[tests ...]
positional arguments:
tests
options:
-h, --help show this help message and exit
--ignore IGNORE
--discover Only print the tests found.
--config CONFIG The path to the config file containing FAILING_TESTS,
IGNORED_TESTS and RUN_ALONE. Defaults to
known_failures.py.
--coverage Enable coverage recording with coverage.py.
--quiet Be quiet. Defaults to True. Also the GEVENTTEST_QUIET
environment variable.
--verbose
--debug Enable debug settings. If the GEVENT_DEBUG environment
variable is not set, this sets it to 'debug'. This can
also enable PYTHONTRACEMALLOC and the debug
PYTHONMALLOC allocators, if not already set. Defaults
to False.
--package PACKAGE Load tests from the given package. Defaults to
gevent.tests.
--processes PROCESSES, -j PROCESSES
Use up to the given number of parallel processes to
execute tests. Defaults to 4.
--no-combine Do not combine tests into process groups.
-u RES1,RES2,..., --use RES1,RES2,...
specify which special resource intensive tests to run.
"all" is the default; "none" may also be used. Disable
individual resources with a leading -.For example,
"-u-network". GEVENTTEST_USE_RESOURCES is used if no
argument is given. To only use one resources, specify
"-unone,resource".
--travis-fold MSG Emit Travis CI log fold markers around the output.
--second-chance Give failed tests a second chance.
--failfast, -x Stop running after the first failure.
运行所有测试的最简单方法就是调用测试运行程序，通常是从源代码签出的根目录调用：
(gevent-env) $ python -mgevent.tests
Running tests in parallel with concurrency 7
...
Ran 3107 tests (skipped=333) in 132 files in 01:52
您还可以使用测试运行程序运行单个gevent测试文件：
(gevent-env) $ python -m gevent.tests test__util.py
Running tests in parallel with concurrency 1
+ /.../python -u -mgevent.tests.test__util
- /.../python -u -mgevent.tests.test__util [Ran 9 tests in 1.1s]
Longest-running tests:
1.1 seconds: /.../python -u -mgevent.tests.test__util
Ran 9 tests in 1 files in 1.1s
或者你可以运行一个猴子补丁的标准库测试：
(gevent-env) $ python -m gevent.tests.test___monkey_patching test_socket.py
Running tests in parallel with concurrency 1
+ /.../python -u -W ignore -m gevent.testing.monkey_test test_socket.py
Running with patch_all(Event=False): test_socket.py
Added imports 1
Skipped testEmptyFileSend (1)
...
Ran 555 tests in 23.042s
OK (skipped=172)
- /.../python -u -W ignore -m gevent.testing.monkey_test test_socket.py [took 26.7s]
Longest-running tests:
26.7 seconds: /.../python -u -W ignore -m gevent.testing.monkey_test test_socket.py
Ran 0 tests in 1 files in 00:27
环境变量#
一些TestRunner选项具有等效的环境变量。尤其是， --quiet 是 GEVENTTEST_QUIET 和 -u 是 GEVENTTEST_USE_RESOURCES .
使用托克斯#
在提交拉请求之前，最好在所有受支持的Python版本上运行测试，并使用prospector/pylint检查代码质量。这就是在CI上执行的操作。在本地，可以使用TOX：：
pip install tox
tox
测量代码覆盖率#
这是在CI上完成的，因此通常不需要在本地完成。
测试运行程序接受 --coverage 参数以通过 coverage.py 包裹。就像这样：
python -m gevent.tests --coverage
coverage combine
coverage html -i
<open htmlcov/index.html>
限制资源使用#
gevent支持标准库测试套件的资源。默认情况下启用所有资源。禁用资源将禁用使用这些资源的测试。例如，要禁用访问外部网络（Internet）的测试，请禁用 network 资源。可以选择：
$ python -m gevent.tests -u-network
环境变量：
$ GEVENTTEST_USE_RESOURCES=-network python -m gevent.tests
