JUnit XML reporting for CI in PyTest - Test Execution Trace

Test Overview

This test runs a simple pytest test case and generates a JUnit XML report. It verifies that the test passes and the XML report file is created for CI integration.

Test Code - pytest

PyTest

import pytest
import os
import sys

def test_addition():
    assert 2 + 3 == 5

if __name__ == '__main__':
    # Run pytest with JUnit XML report output
    retcode = pytest.main(['-v', '--junitxml=report.xml'])
    # Check if report.xml file is created
    assert os.path.exists('report.xml')
    # Exit with pytest return code
    sys.exit(retcode)

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts by running pytest with the --junitxml option to generate XML report	Terminal shows pytest starting, test_addition discovered	-	PASS
2	Pytest runs test_addition function	Test executes assertion 2 + 3 == 5	Assert 2 + 3 == 5 is true	PASS
3	Pytest finishes test run and writes report.xml file	report.xml file is created in current directory	Check that report.xml file exists	PASS
4	Test script asserts report.xml file presence	File system contains report.xml	os.path.exists('report.xml') returns True	PASS
5	Test script exits with pytest return code 0 indicating success	Process ends with exit code 0	-	PASS

Failure Scenario

Failing Condition: The test_addition assertion fails or report.xml file is not created

Execution Trace Quiz - 3 Questions

What does the --junitxml option do in pytest?

A Generates a JUnit XML report file

B Runs tests in parallel

C Skips tests marked as slow

D Enables verbose output

Key Result

Always verify that your CI test runs generate the expected JUnit XML report file to integrate test results with CI dashboards.
