README

PHPUnit Coverage Check - Check the code coverage using the clover report of PHPUnit.

This library will read the clover (or openclover in PHPUnit 12.2+) XML report from PHPUnit and calculate the coverage score. Based on the given threshold, the application will exit OK if the coverage is higher than the threshold or exit with code 1 if the coverage is lower than the threshold.

This library can be used in multiple ways:

• In your continuous deployment environment
• By adding it to a pre-commit hook
• Requiring it as a dev dependency in your composer.json and running it with a composer script.

See GitHub Action, Installation and Usage for more information.

Important

This project is not in any way an official PHPUnit project. Meaning it is not associated with, or endorsed by, the PHPUnit project or its author Sebastian Bergmann.

GitHub Action

A GitHub action is available and can be found in the PHPUnit Coverage Check Action repository, or on the GitHub Marketplace.

Installation

Composer

PHPUnit Coverage Check can be installed using Composer. Add this repository as a dev-dependency to the composer.json file.

$ composer require --dev esi/phpunit-coverage-check:^3.1

To use PHPUnit Coverage Check on an older version of PHP:

• PHP 8.1, use version 1.0.0 (and check 1.x's readme as usage is slightly different):

$ composer require --dev esi/phpunit-coverage-check:^1.0

• PHP 8.2, use version 2.0.0 (and check 2.x's readme)

$ composer require --dev esi/phpunit-coverage-check:^2.0

Phar

Download the phpunit-coverage-check.phar from an available release. It is recommended to check the signature when downloading the Phar from a GitHub Release (with phpunit-coverage-check.phar.asc).

# Adjust the URL based on the latest release
wget -O phpunit-coverage-check.phar "https://github.com/ericsizemore/phpunit-coverage-check/releases/download/3.1.0/phpunit-coverage-check.phar"
wget -O phpunit-coverage-check.phar.asc "https://github.com/ericsizemore/phpunit-coverage-check/releases/download/3.1.0/phpunit-coverage-check.phar.asc"

# Check that the signature matches
gpg --verify phpunit-coverage-check.phar.asc phpunit-coverage-check.phar

# Check the issuer (the ID can also be found from the previous command)
gpg --keyserver hkps://keys.openpgp.org --recv-keys F8367C6E9D7A7028292144AAC9D8B66FF3C06696

rm phpunit-coverage-check.phar.asc
chmod +x phpunit-coverage-check.phar

The Phar files of PHPUnit Coverage Check are signed with a public key associated to admin@secondversion.com.. The key(s) associated with this E-Mail address can be queried at keys.openpgp.org.

Install with Phive

You can also install the PHPUnit Coverage Check Phar with Phive.

If not already using Phive, you can read more about it here, also Phive installation and usage.

Usage

There are two parameters that must be passed to return the code coverage.

1. The location of the clover XML file that PHPUnit has generated.
2. The coverage threshold that is acceptable or 'passing.' Min = 1, Max = 100.

Generate the clover.xml file by using PHPUnit:

Prior to PHPUnit 12.2 (or if you prefer the old clover format of PHPUnit)

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

You can also add the coverage report generation to your PHPUnit configuration file (phpunit.xml.dist for example). You would need to add the following lines inside the <coverage> tag:

    <report>
        <clover outputFile="clover.xml"/>
    </report>

PHPUnit 12.2 and later, for OpenClover

For the experimental OpenClover report in PHPUnit 12.2+

$ php vendor/bin/phpunit --coverage-openclover clover.xml

    <report>
        <openclover outputFile="clover.xml"/>
    </report>

• For more information, see the PHPUnit Documentation.
• Information about the configuration file and commandline options.
• Also see the release notes for PHPUnit 12.2.0.

If installed with Composer

$ php vendor/bin/coverage-check /path/to/clover.xml 100
$ php vendor/bin/coverage-check /path/to/clover.xml 100 --only-percentage

# -O for only-percentage works as well
$ php vendor/bin/coverage-check /path/to/clover.xml 100 -O

# -F or show-files will display coverage per file, formatted in a table
$ php vendor/bin/coverage-check /path/to/clover.xml 100 -F

You can use the Api directly if you wish. The Esi\CoverageCheck\CoverageCheck::nonConsoleCall() method will process and return the data, like how the console application displays it.

    /**
     * Processes the coverage data with the given clover file and threshold, and returns the information
     * like how the Console application will.
     *
     * This is mainly useful for those that may wish to use this library outside the CLI/Console or PHAR.
     */
    public function nonConsoleCall(string $cloverFile, int $threshold = 100, bool $onlyPercentage = false): string

An example usage:

use Esi\CoverageCheck\CoverageCheck;

$check = new CoverageCheck();
$results = $check->nonConsoleCall(__DIR__ . '/tests/fixtures/clover.xml', 90);

echo $results; // Total code coverage is 90.32%

If using the Phar

$ php phpunit-coverage-check.phar /path/to/clover.xml 100
$ php phpunit-coverage-check.phar /path/to/clover.xml 100 --only-percentage

# -O for only-percentage works as well
$ php phpunit-coverage-check.phar /path/to/clover.xml 100 -O

# -F or show-files will display coverage per file, formatted in a table
$ php phpunit-coverage-check.phar /path/to/clover.xml 100 -F

With --only-percentage (or -O) enabled, the CLI command will only return the resulting coverage percentage.

--show-files

With --show-files (or -F), --only-percentage will be ignored. This option parses the clover file for coverage information for each file in the project/package, determine coverage, and display the information in a table.

For example:

$ php coverage-check build/logs/clover.xml 90 -F

--table-width

The --table-width (or -W) option will only have an affect if used with the --show-files option. The only requirement for this particular option is that you must pass an integer value. For example:

$ php coverage-check tests/fixtures/clover.xml 90 -F -W 120

# ...or
$ php coverage-check tests/fixtures/clover.xml 90 --show-files --table-width 120
