暂停 PyTest 并等待用户输入

Question

How can I pause a running test and wait for user input?

I have an unconventional test (python 3, pytest) where I want to "pause" to ask the user (me) for a id code before continuing on with the test.

I'm aware this is not standard, and would like to know how to solve the problem.

Example Test:

    def test_oauth_flow(self):
        url_jwt = auth(id=client_id, scope=scope)
        id_code = webbrowser.open_new(url_jwt)
        # pause wait for user input.
        # use code to complete flow etc....
        auth = auth(code)
        assert auth is 1

Answer 1

Well, it will always depend on what are you testing but my recommendation is to run ContractTests against the external API and record the responses to latter have this data available for your functional tests.

To record the responses you can use vcr, its a Ruby tool: https://github.com/vcr/vcr , but there is also a python implementation (I haven't used it) https://github.com/kevin1024/vcrpy

From here , it's possible but pytest's default capturing needs to be dialed back to sys :

$ pytest --capture=sys ./tests/

Then this test function will halt the tests with a user prompt:

def fd_input(prompt):
    with os.fdopen(os.dup(1), "w") as stdout:
        stdout.write("\n{}? ".format(prompt))

    with os.fdopen(os.dup(2), "r") as stdin:
        return stdin.readline()
