Requirements

interrogate supports Python 3.5 and above.

Installation

interrogate available on PyPI and GitHub. The recommended installation method is pip-installing into a virtualenv:

$ pip install interrogate

Usage

Try it out on a Python project:

$ interrogate [PATH]
RESULT: PASSED (minumum: 80.0%, actual: 100.0%)

Add verbosity to see a summary:

$ interrogate -v [PATH]

Other Usage

Generate a shields.io badge (like this one! ):

$ interrogate --generate-badge PATH
RESULT: PASSED (minumum: 80.0%, actual: 100.0%)
Generated badge to /Users/lynn/dev/interrogate/docs/_static/interrogate_badge.svg

Add it to your tox.ini file to enforce a level of coverage:

[testenv:doc]
deps = interrogate
skip_install = true
commands =
    interrogate --quiet --fail-under 95 src tests

Use it within your code directly:

>>> from interrogate import coverage
>>> cov = coverage.InterrogateCoverage(paths=["src"])
>>> results = cov.get_coverage()
>>> results
InterrogateResults(total=51, covered=48, missing=3, skipped=0)

Configure within your pyproject.toml:

$ interrogate -c pyproject.toml [OPTIONS] [PATHS]...

[tool.interrogate]
ignore-init-method = true
ignore-init-module = false
ignore-magic = false
ignore-semiprivate = false
ignore-private = false
ignore-module = false
fail-under = 95
exclude = ["setup.py", "docs"]
verbose = 0
quiet = false

To view all options available, run interrogate --help:

interrogate -h

                                amount.  [default: 80.0]

  -e, --exclude PATH            Exclude PATHs of files and/or directories.
