Format of return result of pytest_report_teststatus hook function

[Northxw]

  I implemented the pytest_report_teststatus hook method in the conftest.py file, but when I formulated the return value in combination with the official pytest documentation, I had a doubt.

1. Here is the return value example from the official documentation [https://docs.pytest.org/en/latest/reference/reference.html#_pytest.hookspec.pytest_report_teststatus]：

"rerun", "R", ("RERUN", {"yellow": True})

2. The following code is completed by me referring to the official documentation：

import pytest

@pytest.hookimpl
def pytest_report_teststatus(report, config):
    if report.when == 'call' and report.passed:
        return report.outcome, 'T', ("😀", {"yellow": True})
    if report.when == 'call' and report.failed:
        return report.outcome, 'E', "😔"

  So, my doubt is where can I know the format of the detailed words, for example, I can write it like this report.outcome, 'T', ("😀", {"yellow": True}), or I can write it like this report.outcome, 'T', "😀".

  Or, where can I learn about the resulting format of verbose word，Such as ("😀", {"yellow": True}) and "😀".

  This is a small and detailed question, but I'm looking forward to an answer, thanks a lot!
