Print playwright browser in pytest terminal header

I have pytest set up with playwright and can run it with a docker compose command:

docker compose run test pytest /tests --browser-channel chrome

Which outputs:

I want to include the browser names in each session. I've tried using the browser_name fixture in the pytest_report_header hook, but fixtures don't work in the report hooks and it errors out.

Solution

  • I was able to add this by checking the config.option Namespace and returning the browser value if found.

    Added to my conftest.py file:

    def pytest_report_header(config):
    if config.get_verbosity() == 0:
        browser = None
        if config.option.browser_channel is not None:
            browser = config.option.browser_channel
        elif len(config.option.browser) > 0:
            browser = ", ".join(config.option.browser)

        if browser is not None:
            return f"browser: {browser}"

    This is still a little buggy:
