pytest's html reporter doesn't take/show screenshot in the test reports for pytest-playwright based tests


I tried to run my first playwright test using pytest-playwright and the test runs fine but when I tried to use the pytest html reporter to show me the report with a screenshot for a failed test it doesn't work

pytest version == 7.0.1 pytest-playwright version == 0.2.3

Test which is expected to fail:

    def test_pw():
    with sync_playwright() as p:
        browser = p.chromium.launch(headless=False)
        page = browser.new_page()
        page.goto("http://www.html")
        browser.close()

test report without any screenshot for failed test

Run command: pytest --html report_pw1.html

Can anyone please suggest what am i missing here? I read the docs for pytest html and it says that a screenshot should automatically be included by default for failed tests but its not happening so


Solution

  • You have to create conftest.py file at the root level. I adapted this code from pytest-html official documentation:

    # conftest.py
    import pytest
    
    @pytest.hookimpl(hookwrapper=True)
    def pytest_runtest_makereport(item, call):
        pytest_html = item.config.pluginmanager.getplugin("html")
        outcome = yield
        screen_file = ''
        report = outcome.get_result()
        extra = getattr(report, "extra", [])
        if report.when == "call":
            if report.failed and "page" in item.funcargs:
                page = item.funcargs["page"]
                screenshot_dir = Path("screenshots")
                screenshot_dir.mkdir(exist_ok=True)
                screen_file = str(screenshot_dir / f"{slugify(item.nodeid)}.png")
                page.screenshot(path=screen_file)
            xfail = hasattr(report, "wasxfail")
            if (report.skipped and xfail) or (report.failed and not xfail):
                # add the screenshots to the html report
                extra.append(pytest_html.extras.png(screen_file))
            report.extra = extra
    

    You have to install pytest-playwright:

    pip install pytest-playwright
    

    Then your tests have access to the page fixture (and it is available for item.funcargs in the conftest.py file):

    def test_example_is_failing(page):
        page.goto("https://example.com")
        assert page.inner_text('h1') == 'Any text to make it fail'
    

    I am sure there should be a better way if we dig more in the documentation. I used these links:
