pytest-html 添加自定义测试结果报告

Question

I'm using pytest0html to generate my html report. my test record tested values and I need to show a table of this values with prettytable in case of success. I think that i need to implement this hook:

@pytest.mark.optionalhook
def pytest_html_results_table_html(report, data):
    if report.passed:
        del data[:]
        data.append(my_pretty_table_string)
        # or data.append(report.extra.text)

But how to pass my_pretty_table_string to the hook function or how to edit report.extra.text from my test function ? Thank you for your help

Answer 1

Where is your my_pretty_table_string stored and generated?

Please give more details to your question so we can help :)

pytest_html_results_table_html gets report object from pytest_runtest_makereport hook. So you need to implement pytest_runtest_makereport to add your data to the result at 'call' step.

@pytest.mark.hookwrapper
def pytest_runtest_makereport(item, call):
   outcome = yield # get makereport outcome
   if call.when == 'call':
      outcome.result.my_data = <your data object goes here>

then you can access report.my_data in pytest_html_results_table_html hook.

Hey @Alexper I wanna do something like what @user210267 but in my case I have a wrapper around he logger so when failure it's logging out (to a .txt file as well) a DataFrame with the difference after performed the assertion. My pytest_runtest_makereport looks like:

@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item, call):
  pytest_html = item.config.pluginmanager.getplugin("html")
  outcome = yield
  report = outcome.get_result()
  extra = getattr(report, "extra", [])

  if report.when == "call":
      # always add url to report
      extra.append(pytest_html.extras.url("http://www.myreport.com/"))
      xfail = hasattr(report, "wasxfail")

      report_dir = config.named_folders.test_reports
      now = datetime.datetime.now().strftime('%Y%m%d_%H%M%S')
      report_dir = report_dir.replace("[TIMESTAMP]", now)
    
      if (report.skipped and xfail) or (report.failed and not xfail):
         screenshot = report.nodeid.replace("::", "_") + ".png" 
         screenshot = "screenshot_" + now + ".png"
         dest_file = os.path.join(os.path.dirname(__file__), screenshot)

         feature_request = item.funcargs['request']
         driver = feature_request.getfixturevalue('setup')
         driver.save_screenshot(dest_file)
         browser_logs = driver.get_log('browser')

        if browser_logs:
            print(browser_logs)
            extra.append(pytest_html.extras.html(f"<div>{browser_logs}</div>"))

        extra.append(pytest_html.extras.image(dest_file))
        
    report.extra = extra

So I wanna add something like this:

+----+----------+---------+
|    | Value 1  | Value 2 |
|----+----------+---------|
|  0 | title    | Title   |
+----+----------+---------+

that is basically what i'm erroring out to the logs.

I have the function that returns and print out that dataframe but how can I get that and inject it to the report?
