README

Display the code coverage for a project using a clover.xml file, optionally enforcing a minimum code coverage percentage.

This package is designed to be used in your CI/CD or automated testing process (i.e., using GitHub Workflows).

The concept for this package is based on this article.

``

Note on PHP 7.x support: If you are using PHP 7.x, use the 1.x version of this package.

Installation

composer require permafrost-dev/coverage-check --dev

Usage

Specify a valid clover.xml file and (optionally) a minimum coverage percentage to require using the --require or -r flag. A percentage can be either a whole number (integer) or a decimal (float).

If you specify the --require/-r flag, the check will fail if coverage percent is below the value you provide, and the process exit code will be non-zero.

If you don't specify the --require/-r flag, only the percentage of code coverage will be displayed and the exit code will always be zero.

./vendor/bin/coverage-check clover.xml
./vendor/bin/coverage-check clover.xml --require=50
./vendor/bin/coverage-check clover.xml -r 80.5
./vendor/bin/coverage-check clover.xml -m statement -r 75
./vendor/bin/coverage-check clover.xml --precision=1

Available Options

Metric fields

The field that is used to calculate code coverage can be specified using the --metric=<name> or -m <name> option.

Valid field names are element (the default), statement, and method.

Generating clover-format coverage files

PHPUnit can generate coverage reports in clover format:

./vendor/bin/phpunit --coverage-clover clover.xml

Sample Github Workflow

        php: [8.1, 8.0, 7.4, 7.3]

    name: P${{ matrix.php }} - ${{ matrix.os }}

    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Setup PHP

      - name: Install dependencies
        run: composer update --prefer-stable --prefer-dist --no-interaction

      - name: Execute tests
        run: ./vendor/bin/phpunit --coverage-clover clover.xml

      - name: Enforce 75% code coverage
        run: ./vendor/bin/coverage-check clover.xml --require=75 --precision=2
