how to get trace and failed screenshot after yield in function scope

[vasilyevi]

I need to upload trace and screenshot made on failure at the end of each test to my personal external system, but in fixture, in function scope trace and screenshots does not exist. It will be created after the fixture itself. So, my question is how to deal with them at the end of each test?

could you please share the relevant snippets of your code?

Running with --screenshot="only-on-failure" and --tracing=on

@pytest.fixture(scope="function", autouse=True)
def logged_in_user(page: Page, request, playwright: Playwright):
   //do login
    yield
   // do after test and here I need to get the trace.zip and screenshot if test is failed, but I'm not able as both does not exist yet. 
   //Which is weird as the test itself is completed and especially weird for screenshot on failure as I assume it have to be taken 
   //exactly after the test is failed

If you yield the test case is not considered as finished yet. I don't know your exact use case, so can't recommend precise solution - but I'd think about getting rid of yield.

The use case is pretty simple, once any test is completed I need to upload artifacts(trace and screenshot) of a test to a reporting tool. To upload them I somehow need to get their path in system.
One more time. Let's say I use testrail. Once a test is completed I need to send an API request to testrail with the test status and attach to testrail test result an artifacts.
If yield is not considered as finished yet, is there any other ways?

By "use case" I meant "why do you have to use yield inside your test" :) You can try to use return instead, but the best way would be probably to end it with assertion.

[vasilyevi]

To be honest not sure we understand each other. What do you mean to use return instead?
Could you give a small example?

Ok, let's reverse the question - why you're using yield keyword in the middle of your testcase? If I understand why you're doing this then we can think about the solution here.

[vasilyevi]

Because I need to get the trace and screenshot after the test execution, once the test itself is completed. As far as I understand fixture + yield is the only one way to do that(or recommended).

I think I messed up :( For some reason I thought I'm looking at the test function (your code snippet), but in fact it's a fixture. So my advice was for completely different problem... apologies for that.

For your issue - yeah, I think it should work the way you described. Some time ago I was trying to rename the video files (because videos recorded by Playwright are named with quite random chars, so if you run more than one test it's hard to tell which video is for which). Suprisingly the videos were not added "on the fly" after each test case, but after WHOLE test run. It might be the case with the screenshots - maybe they are in the temp folder? (unless the screenshots are not recorded even after whole testrun finishes - in such case I have no idea :) )

Hello, you might need to look at Pytest Hooks and perform actions after each test finishes/failed.
