Running Backend API Tests

Quick Start

Option 1: Using the test runner script (Recommended)

./run_tests.sh

Option 2: Using npm script

npm run test:backend

Option 3: Manual command

export PYTHONPATH=$(pwd)
export SKIP_DEEPFACE_IN_TESTS=1
./venv/bin/python3 -m pytest tests/ -v

Where to See Test Results

Test results are displayed in your terminal/console where you run the command.

Example Output

When tests run successfully, you'll see output like:

tests/test_api_auth.py::TestLogin::test_login_success_with_valid_credentials PASSED
tests/test_api_auth.py::TestLogin::test_login_failure_with_invalid_credentials PASSED
tests/test_api_auth.py::TestTokenRefresh::test_refresh_token_success PASSED
...
========================= 26 passed in 2.34s =========================

Understanding the Output

• PASSED (green) - Test passed successfully
• FAILED (red) - Test failed (shows error details)
• ERROR (red) - Test had an error during setup/teardown
• SKIPPED (yellow) - Test was skipped

Verbose Output

The -v flag shows:

• Each test function name
• Pass/fail status for each test
• Summary at the end

Detailed Failure Information

If a test fails, pytest shows:

• The test that failed
• The assertion that failed
• The actual vs expected values
• A traceback showing where the error occurred

Test Coverage

To see coverage report:

export PYTHONPATH=$(pwd)
export SKIP_DEEPFACE_IN_TESTS=1
./venv/bin/python3 -m pytest tests/ --cov=backend --cov-report=term-missing

This shows:

• Which lines of code are covered by tests
• Which lines are missing coverage
• Overall coverage percentage

Running Specific Tests

Run a single test file

./venv/bin/python3 -m pytest tests/test_api_auth.py -v

Run a specific test class

./venv/bin/python3 -m pytest tests/test_api_auth.py::TestLogin -v

Run a specific test

./venv/bin/python3 -m pytest tests/test_api_auth.py::TestLogin::test_login_success_with_valid_credentials -v

CI/CD Test Results

In CI (GitHub Actions/Gitea Actions), test results appear in:

1. CI Logs - Check the "Run backend tests" step in the workflow
2. Test Artifacts - JUnit XML files are generated for test reporting tools
3. Coverage Reports - Coverage XML files are generated

Troubleshooting

Tests not showing output?

• Make sure you're running in a terminal (not an IDE output panel that might hide output)
• Try adding -s flag: pytest tests/ -v -s (shows print statements)

Tests hanging?

• Check if database is accessible
• Verify SKIP_DEEPFACE_IN_TESTS=1 is set (prevents DeepFace from loading)

Import errors?

• Make sure virtual environment is activated or use ./venv/bin/python3
• Verify all dependencies are installed: ./venv/bin/pip install -r requirements.txt
