eqator 2.3.0

Checking the Django project for quality

eqator

Checking the Django project for quality. It can be convenient if you include it in CI.

Used packages:

• django unittest - unit testing in Django.
• flake8 - linter of source code.
• radon - tool that computes various metrics from the source code.
• bandit - a security linter from PyCQA.
• coverage - a test coverage for unittest.

Quickstart

Install with pip:

pip install eqator

Add the eqator to your INSTALLED_APPS:

# settings.py

INSTALLED_APPS = [
    # ...
    'eqator',
]

To use Lighthouse scoring, install Lighthouse CI with npm:

npm install -g @lhci/cli

Check your project:

python manage.py qa

Check your project by separate options.

Run checking style guide with flake8:

python manage.py qa -f

python manage.py qa --flake

Run checking cyclomatic complexity with radon

python manage.py qa -r

python manage.py qa --radon

Run security lint with bandit

python manage.py qa -l

python manage.py qa --linter

Run django project migrations check

python manage.py qa -m

python manage.py qa --migrations

Run django unittest

python manage.py qa -t

python manage.py qa --tests

Run django unit tests for garpix_page

python manage.py qa -p

python manage.py qa --garpix_page

Lighthouse CI check:

(requires Lighthouse CI installed)

python manage.py qa -lh

python manage.py qa --lighthouse

Run test coverage check

python manage.py qa -c

python manage.py qa --test_coverage

Note, that you need to add TEST_COVERAGE_RATE variable to your settings.py file (default value is 70):

TEST_COVERAGE_RATE = 70

Optionally, do not save Lighthouse CI report files:

python manage.py qa --all --clear-reports

Check your project with all logs:

python manage.py qa --verbose

You can also add add SENTRY_CHECK_METHOD and LIGHTHOUSE_CHECK_METHOD variables to your settings.py file to controle the sentry SDK and lighthouse CI checking methods:

# settings.py
SENTRY_CHECK_METHOD = 'error'
LIGHTHOUSE_CHECK_METHOD = 'warning'
