pytest命令行参数失败

Question

I have added conftest.py at the same directory level as my test file . The content of my conftest.py :

 import pytest

    def pytest_addoption(parser):
        parser.addoption("--l", action="store", help="Get license value")
    @pytest.fixture
    def lic(request):
        return request.config.getoption("--l")

and following is my test file def

   def  test(lic):
        print "testing license : %s"%lic
        assert 0

But i still get following error:

   pytest  .\source\test_latestLinuxAgent.py --l=test
        pytest : usage: pytest [options] [file_or_dir] [file_or_dir] [...]
        At line:1 char:1
        + pytest  .\source\test_latestLinuxAgent.py --l=test


        pytest: error: ambiguous option: --l=test could match --lf, --last-failed

Answer 1

As the response says, --l option is ambiguous. What does it mean?

Let me explain it with an example. If you have --zaaaa option, the shortcut for it is --z . However, there is one condition: --zaaaa must be the only option starting with z char. Otherwise, the interpreter does not know which option should be chosen.

You can't define --l option because there are two options starting with l char: --lf and --last-failed .

I suggest creating non-conflicting option, --license would be nice.
