pytest-json-report makes pytest_report_teststatus hook to run twice for each step

[briceparmentier]

Hi there!
I'm trying to understand to behavior of the pytest_report_teststatus hook, because in my environment (which does not seem to be that different from what I can see on the internet) I'm getting it called twice for each of the steps in setup, teardown and call.

I tried to run in another project written from scratch, so below is what I hope to be a clear explanation of what I have found so far.

I have the following code in my conftest.py file:

import pytest


def pytest_report_teststatus(report, config):
    print(report.when, report.outcome)


@pytest.fixture(scope="function")
def myfixture():
    print("################################ setup")
    yield
    print("################################ teardown")

Then I have 3 tests files as below:
tests_script1.py:

import pytest


@pytest.mark.skip(reason="reason")
def test_machin1(myfixture):
    print("something 1")

tests_script2.py:

def test_thing2():
    print("something 2")

tests_script3.py:

def test_thing3():
    print("something 3")

If I run the command pytest -s in this folder, I'm getting the following result:

Now if I edit the conftest.py file and add the following hook with the line that activates the json report plugin:

def pytest_configure(config):
    config.option.json_report = True

and then run the command again, I get the following output:

As you can see, the pytest_report_teststatus is now called twice for each step.

Which causes me a problem as I want to submit tests results to another tool (using a HTTP request), so I'm getting two results for one test (whatever the result).

Thank you a lot in advance for the attention you can bring to this and help me fix it, or find a workaround.

Cheers,
