pytest文档10-命令行传参addoption
前言
命令行参数是根据命令行选项将不同的值传递给测试函数，比如平常在cmd执行”pytest —html=report.html”,这里面的”—html=report.html“就是从命令行传入的参数
对应的参数名称是html，参数值是report.html
contetest配置参数
1.首先需要在contetest.py添加命令行选项,命令行传入参数”—cmdopt“, 用例如果需要用到从命令行传入的参数，就调用cmdopt函数：
# content of conftest.py import pytest def pytest_addoption(parser): parser.addoption( "--cmdopt", action="store", default="type1", help="my option: type1 or type2" ) @pytest.fixture def cmdopt(request): return request.config.getoption("--cmdopt")
2.测试用例编写案例
# content of test_sample.py import pytest def test_answer(cmdopt): if cmdopt == "type1": print("first") elif cmdopt == "type2": print("second") assert 0 # to see what was printed if __name__ == "__main__": pytest.main(["-s", "test_case1.py"])
cmd打开，输入指令启动，也可以在pycharm里面右键执行上面代码
$ pytest -s test_sample.py
运行结果：
>pytest -s ============================= test session starts ============================= test_sample.py first F ================================== FAILURES =================================== _________________________________ test_answer _________________________________ cmdopt = 'type1' def test_answer(cmdopt): if cmdopt == "type1": print("first") elif cmdopt == "type2": print("second") > assert 0 # to see what was printed E assert 0 test_case1.py:8: AssertionError ========================== 1 failed in 0.05 seconds ===========================
带参数启动
1.如果不带参数执行，那么传默认的default=”type1”，接下来在命令行带上参数去执行
$ pytest -s test_sample.py —cmdopt=type2
test_sample.py second F ================================== FAILURES =================================== _________________________________ test_answer _________________________________ cmdopt = 'type2' def test_answer(cmdopt): if cmdopt == "type1": print("first") elif cmdopt == "type2": print("second") > assert 0 # to see what was printed E assert 0 test_case1.py:8: AssertionError ========================== 1 failed in 0.05 seconds ===========================
2.命令行传参数有两种写法，还有一种分成2个参数也可以的,参数和名称用空格隔开
$ pytest -s test_case1.py —cmdopt type2
