pytest 运行完用例之后会生成一个 .pytest_cache 的缓存文件夹,用于记录用例的ids和上一次失败的用例。
方便我们在运行用例的时候加上--lf 和 --ff 参数,快速运行上一次失败的用例。
--lf, --last-failed 只重新运行上次运行失败的用例(或如果没有失败的话会全部跑)
--ff, --failed-first 运行所有测试,但首先运行上次运行失败的测试(这可能会重新测试,从而导致重复的fixture setup/teardown)
pytest -h
查看命令行参数,关于 cache 参数的使用方式
> pytest -h
--lf, --last-failed rerun only the tests that failed at the last
run (or all if none failed)
--ff, --failed-first run all tests, but run the last failures first.
This may re-order tests and thus lead to repeated fixture setup/teardown.
--nf, --new-first run tests from new files first, then the rest of the tests sorted by file mtime
--cache-show=[CACHESHOW]
show cache contents, don‘t perform collection or tests. Optional argument: glob(default: ‘*‘).
--cache-clear remove all cache contents at start of test run.
参数说明:
--last-failed
仅运行上一次失败的用例--failed-first
运行全部的用例,但是上一次失败的用例先运行--new-first
根据文件插件的时间,新的测试用例会先运行案例
def test_01():
a = "hello"
b = "hello"
assert a == b
def test_02():
a = "hello"
b = "hello world"
assert a == b
def test_03():
a = "hello"
b = "hello world"
assert a in b
def test_04():
a = "hello"
b = "hello world"
assert a not in b
命令行输入 运行完成后,会有2个用例失败,2个用例成功
collecting ...
case/test_1.py ? 25% ██▌
case/test_1.py ?? 75% ███████▌
case/test_1.py ? 100% ██████████
运行完成后,会在当前的目录生成一个 .pytest_cache
的缓存文件夹,层级结构如下
lastfailed 文件记录上一次运行失败的用例
{
"test_x.py::test_02": true,
"test_x.py::test_04": true
}
nodeids 文件记录所有用例的节点
[
"test_x.py::test_01",
"test_x.py::test_02",
"test_x.py::test_03",
"test_x.py::test_04"
]
于是可以通过 pytest --cache-show 命令查看cache目录
