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 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
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
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
