Coverage Report using pytest-cov

[billsioros]

Hello 👋🏽 everyone,

I'm trying to create a coverage report for my application and I noticed that my controllers report a 0% coverage even though I use the TestClient to perform requests. My configuration (pyproject.toml) is as follows:

[tool.pytest.ini_options]
pythonpath = [ "src" ]
asyncio_default_fixture_loop_scope = "session"
addopts = "-vv --color=yes --cov=api --cov-report=term-missing --cov-report=html"
log_cli = false
log_cli_date_format = "%Y-%m-%d %H:%M:%S"
log_cli_format = "%(asctime)s %(levelname)s %(message)s"
log_cli_level = "INFO"
python_files = "test_*.py"
python_functions = "test_*"
testpaths = "tests"
markers = [
  "unit: Unit tests",
  "integration: Integration tests",
  "skip: Skip tests",
  "xfail: Expected to fail tests",
  "asyncio: Mark test to be run with pytest-asyncio",
]

[tool.coverage.paths]
source = [ "src" ]

[tool.coverage.run]
branch = true
source = [ "api" ]
concurrency = [ "greenlet", "thread" ]

[tool.coverage.report]

Could you please assist me?

Thanks! 😋

@billsioros I'm tried to test a simple Hello World application. Here is the project tree.

.
├── htmlcov
├── __pycache__
├── pyproject.toml
├── src
│   ├── __init__.py
│   └── server.py
└── tests
    ├── conftest.py
    ├── __init__.py
    └── test_app.py

I modified your pyproject.toml like this

[tool.pytest.ini_options]
pythonpath = ["src"]
asyncio_default_fixture_loop_scope = "session"
log_cli = false
log_cli_date_format = "%Y-%m-%d %H:%M:%S"
log_cli_format = "%(asctime)s %(levelname)s %(message)s"
log_cli_level = "INFO"
python_files = "test_*.py"
python_functions = "test_*"
testpaths = "tests"
markers = [
  "unit: Unit tests",
  "integration: Integration tests",
  "skip: Skip tests",
  "xfail: Expected to fail tests",
  "asyncio: Mark test to be run with pytest-asyncio",
]

[tool.coverage.report]
fail_under = 90

[tool.coverage.run]
branch = true
source = ["src"]
disable_warnings = ['no-data-collected']
command_line = "-m pytest -vv --color=yes --cov=src --cov-report=term-missing --cov-report=html"

You need to coverage run from the src directory and everything works (tests and coverage).
Hope this helps.

Thank you very much! Such a silly mistake 😛
