Running PyTest in GitHub Actions - Test Execution Trace

Test Overview

This test runs a simple PyTest test case inside a GitHub Actions workflow. It verifies that the test executes successfully and the assertion passes.

Test Code - PyTest

PyTest

import pytest

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

# GitHub Actions workflow file (.github/workflows/python-test.yml):
# name: Python package
# on: [push]
# jobs:
#   build:
#     runs-on: ubuntu-latest
#     steps:
#     - uses: actions/checkout@v3
#     - name: Set up Python 3.12
#       uses: actions/setup-python@v4
#       with:
#         python-version: '3.12'
#     - name: Install dependencies
#       run: |
#         python -m pip install --upgrade pip
#         pip install pytest
#     - name: Run tests
#       run: |
#         pytest

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	GitHub Actions workflow starts on push event	GitHub runner environment (ubuntu-latest) is ready	-	PASS
2	Checkout repository code using actions/checkout@v3	Test code and workflow files are available on runner	-	PASS
3	Set up Python 3.12 environment using actions/setup-python@v4	Python 3.12 is installed and active	-	PASS
4	Install pytest using pip	pytest package is installed in the environment	-	PASS
5	Run pytest command to execute test_addition	pytest runs test_addition function	assert 2 + 3 == 5 is True	PASS
6	PyTest reports test result	Test passed with no failures	Test summary shows 1 passed, 0 failed	PASS

Failure Scenario

Failing Condition: The assertion in test_addition fails (e.g., assert 2 + 3 == 6)

Execution Trace Quiz - 3 Questions

What does the GitHub Actions step 'actions/checkout@v3' do in this test?

A It downloads the repository code to the runner

B It installs Python on the runner

C It runs the pytest tests

D It uploads test results to GitHub

Key Result

Always include a simple test with a clear assertion to verify your test environment setup works correctly in CI pipelines like GitHub Actions.
