pytest-race 0.1.1

说明

pytest的竞赛条件测试仪

引入start_race运行竞赛条件测试的fixture。

要求

• Python2.7+，3.3+
• Pytest 2.9.0+

用法

您可以在测试中使用start_race夹具，如下所示：

fromtimeimportsleepACCUMULATOR=0# This global var is race conditions prone.deftest_race(start_race):fromrandomimportrandintdefactual_test():globalACCUMULATORincrement=randint(1,10000)accumulator=ACCUMULATORsleep(1)# Simulate some lag.ACCUMULATOR+=increment# By that moment ACCUMULATOR should have been updated# by another thread. Let's try to prove it.# Using simple `assert` as usual for pytest.assertaccumulator+increment==ACCUMULATOR# Let's run `actual_test` in 2 threads.start_race(threads_num=2,target=actual_test)

start_race接受以下参数：

• threads_num-要同时运行的线程数。
• target-可在线程中运行的实际测试调用。
