只需一步,快速开始

前言之前一篇文章pytest的一些高阶用法记录了一些高阶的用法,这边继续实践一些操作
1.报告  pytest-html这是一版简单的html报告
安装命令
pip install pytest-html执行脚本的时候,带上需要保存报告的地址和报告名称即可
pytest demo_fixture.py --html=./../report/report.html这边会在脚本的上级目录,report文件夹中,生成一个html报告,报告内容如下:

2.指定运行用例可以看到 报告中Test这一列,出现  demo_fixture.py::Test1::()::test_1 这种格式,这其实就是pytest指定运行部分用例的方法,可以试验一下
import pytest@pytest.fixture(scope="class",autouse=True)def preclass():    print("beore class ")    yield    print("after class")@pytest.fixture(scope="module",autouse=True)def premodule():    print("beore module ")    yield    print("after module")@pytest.fixture(scope="function",autouse=True)def pretest():    print("beore function ")    yield    print("after function")class Test1(object):    def test_1(self):        print("this is test1")        assert 1==1    def test_2(self):        print("this is test2")        assert 1+2 ==3class Test2(object):    def test_3(self):        print("this is test3")        assert  3+1 ==4    def test_4(self):        print("this is test4")        assert  3+2 ==5如果我们想只执行Test1 的测试用例,那么执行命令:
pytest -sq demo_fixture_decorator.py::Test1其结果如下:

如果只想执行Test2中的test_3,那么命令如下:
pytest -sq demo_fixture_decorator.py::Test2::test_3其结果如下:




test_3.png


仅执行了test_3
同时也支持多个条件,如下:
pytest -sq demo_fixture_decorator.py::Test2::test_3 demo_fixture_decorator.py::Test13.conftestconftest.py 定一个共享的fixture(备注:文件名固定为conftest.py 不可以修改)
一般放在testcase目录中,每个子目录下也可以有conftest.py,优先子目录中的conftest.py中fixture
定一个conftest.py如下:
import pytest@pytest.fixture(scope="session",autouse="True")def before():    print("this is conftest")当我们再次执行
pytest -sq demo_fixture_decorator.py::Test2::test_3其结果如下:




conftest.png

对比可以发现,test_3 执行前,先执行了conftest中的代码
4.markpytest支持自定义一些标签,在执行脚本的时候,执行指定某些标签或者非某些标签的用例
首先查看pytest 自带的markers
pytest  --markers@pytest.mark.no_cover: disable coverage for this test.@pytest.mark.run: specify ordering information for when tests should run in relation to one another. Provided by pytest-ordering. See also: http://pytest-ordering.readthedocs.org/@pytest.mark.flaky(reruns=1, reruns_delay=0): mark test to re-run up to 'reruns' times. Add a delay of 'reruns_delay' seconds between re-runs.....@pytest.mark.parametrize(argnames, argvalues): call a test function multiple times passing in different arguments in turn. @pytest.mark.usefixtures(fixturename1, fixturename2, ...): mark tests as needing all of the specified fixtures. see https://docs.pytest.org/en/latest/fixture.html#usefixtures@pytest.mark.tryfirst: mark a hook implementation function such that the plugin machinery will try to call it first/as early as possible.@pytest.mark.trylast: mark a hook implementation function such that the plugin machinery will try to call it last/as late as possible.可以看到之前提到的一些,如:
参数化用的@pytest.mark.parametrizefixture用的@pytest.mark.usefixtures失败重跑用的@pytest.mark.flaky(reruns=1, reruns_delay=0)等等我们可以自定义写mark
新增pytest.ini,内容如下:
[pytest]markers=    P0: level P0    P1: level p1    P2: level p2    dong: testcase created by dong    mandy: testcase created by mandy    cm: testcase about cm    pd: testcase about pd再次执行
pytest  --markers@pytest.mark.P0: level P0@pytest.mark.P1: level p1@pytest.mark.P2: level p2@pytest.mark.dong: testcase created by dong@pytest.mark.mandy: testcase created by mandy@pytest.mark.cm: testcase about cm@pytest.mark.pd: testcase about pd@pytest.mark.no_cover: disable coverage for this test.@pytest.mark.run: specify ordering information for when tests should run in relation to one another. Provided by pytest-ordering. See also: http://pytest-ordering.readthedocs.org/@pytest.mark.flaky(reruns=1, reruns_delay=0): mark test to re-run up to 'reruns' times. Add a delay of 'reruns_delay' seconds between re-runs....之前自定义的标签,已经加入了
那么如何使用这些标签呢?
import pytest@pytest.mark.dong@pytest.mark.P1@pytest.mark.cmclass Test1(object):    def test_1(self):        print("this is test1")        assert 1==1    @pytest.mark.P0    def test_2(selfs):        print("this is test2")        assert 1+2 ==3@pytest.mark.mandy@pytest.mark.P0class Test2(object):    def test_3(self):        print("this is test3")        assert  3+1 ==4可以看到在脚本中加上了我们自定义的标签,如果向指定执行部分标签的用例执行方法:
pytest -sq -m "P0" demo_mark.py  ---仅执行P0级的用例结果如下,和预期的一致,仅运行P0级的用例




P0

同时也支持一些逻辑
pytest -sq -m "P0 and cm" demo_mark.py    ---运行cm模块的P0级用例预期结果:仅运行 test_2



P0 and cm.png

这一段,可以参考官网文档.
也可以根据用例名称进行筛选  -k
pytest -sq -k 2 demo_mark.py预期只会执行 名字中包含2 的用例,即执行 test_2 和 Test2
