php-coveralls

PHP client library for Coveralls.

Prerequisites

• PHP 5.5+ for 2.x or 5.3+ for 1.x
• On GitHub
• Building on Travis CI, CircleCI, Jenkins or Codeship
• Testing by PHPUnit or other testing framework that can generate clover style coverage report

Installation

Download phar file

We started to create a phar file, starting from the version 0.7.0 release. It is available at the URLs like:

https://github.com/php-coveralls/php-coveralls/releases/download/v2.4.3/php-coveralls.phar

Download the file and add exec permissions:

$ wget https://github.com/php-coveralls/php-coveralls/releases/download/v2.4.3/php-coveralls.phar
$ chmod +x php-coveralls.phar

Install by composer

To install php-coveralls with Composer, run the following command:

$ composer require --dev php-coveralls/php-coveralls

If you need support for PHP versions older than 5.5, you will need to use a 1.x version:

$ composer require --dev 'php-coveralls/php-coveralls:^1.1'

You can see this library on Packagist.

Composer installs autoloader at ./vendor/autoloader.php. If you use php-coveralls in your php script, add:

require_once 'vendor/autoload.php';

If you use Symfony2, autoloader has to be detected automatically.

Use it from your git clone

Or you can use git clone command:

# HTTP
$ git clone https://github.com/php-coveralls/php-coveralls.git
# SSH
$ git clone [email protected]:php-coveralls/php-coveralls.git

Configuration

Currently php-coveralls supports clover style coverage report and collects coverage information from clover.xml.

PHPUnit

Make sure that phpunit.xml.dist is configured to generate "coverage-clover" type log named clover.xml like the following configuration:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit ...>
    <logging>
        ...
        <log type="coverage-clover" target="build/logs/clover.xml"/>
        ...
    </logging>
</phpunit>

You can also use --coverage-clover CLI option.

phpunit --coverage-clover build/logs/clover.xml

phpcov

Above settings are good for most projects if your test suite is executed once a build and is not divided into several parts. But if your test suite is configured as parallel tasks or generates multiple coverage reports through a build, you can use either coverage_clover configuration in .coveralls.yml (see below coverage clover configuration section) to specify multiple clover.xml files or phpcov for processing coverage reports.

composer.json

    "require-dev": {
        "php-coveralls/php-coveralls": "^2.4",
        "phpunit/phpcov": "^2.0"
    },

phpunit configuration

Make sure that phpunit.xml.dist is configured to generate "coverage-php" type log:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit ...>
    <logging>
        ...
        <log type="coverage-php" target="build/cov/coverage.cov"/>
        ...
    </logging>
</phpunit>

You can also use --coverage-php CLI option.

# use --coverage-php option instead of --coverage-clover
phpunit --coverage-php build/cov/coverage-${component_name}.cov

phpcov configuration

And then, execute phpcov.php to merge coverage.cov logs.

# get information
php vendor/bin/phpcov.php --help

# merge coverage.cov logs under build/cov
php vendor/bin/phpcov.php merge --clover build/logs/clover.xml build/cov

# in case of memory exhausting error
php -d memory_limit=-1 vendor/bin/phpcov.php ...

clover.xml

php-coveralls collects count attribute in a line tag from clover.xml if its type attribute equals to stmt. When type attribute equals to method, php-coveralls excludes its count attribute from coverage collection because abstract method in an abstract class is never counted though subclasses implement that method which is executed in test cases.

<!-- this one is counted as code coverage -->
<line num="37" type="stmt" count="1"/>
<!-- this one is not counted -->
<line num="43" type="method" name="getCommandName" crap="1" count="1"/>

Travis CI

Add php php-coveralls.phar or php vendor/bin/php-coveralls to your .travis.yml at after_success.

# .travis.yml
language: php
php:
  - 5.5
  - 5.4
  - 5.3

matrix:
  allow_failures:
    - php: 5.5

install:
  - curl -s http://getcomposer.org/installer | php
  - php composer.phar install --dev --no-interaction
script:
  - mkdir -p build/logs
  - php vendor/bin/phpunit -c phpunit.xml.dist

after_success:
  - travis_retry php vendor/bin/php-coveralls
  # or enable logging
  - travis_retry php vendor/bin/php-coveralls -v

CircleCI

Enable Xdebug in your circle.yml at dependencies section since currently Xdebug extension is not pre-enabled. composer and phpunit are pre-installed but you can install them manually in this dependencies section. The following sample uses default ones.

machine:
  php:
    version: 5.4.10

## Customize dependencies
dependencies:
  override:
    - mkdir -p build/logs
    - composer install --dev --no-interaction
    - sed -i 's/^;//' ~/.phpenv/versions/$(phpenv global)/etc/conf.d/xdebug.ini

## Customize test commands
test:
  override:
    - phpunit -c phpunit.xml.dist

Add COVERALLS_REPO_TOKEN environment variable with your coveralls repo token on Web UI (Tweaks -> Environment Variable).

Codeship

You can configure CI process for Coveralls by adding the following commands to the textarea on Web UI (Project settings > Test tab).

In the "Modify your Setup Commands" section:

curl -s http://getcomposer.org/installer | php
php composer.phar install --dev --no-interaction
mkdir -p build/logs

In the "Modify your Test Commands" section:

php vendor/bin/phpunit -c phpunit.xml.dist
php vendor/bin/php-coveralls

Next, open Project settings > Environment tab, you can set COVERALLS_REPO_TOKEN environment variable.

In the "Configure your environment variables" section:

COVERALLS_REPO_TOKEN=your_token

GitHub Actions

Add a new step after phpunit generate coverage report.

- name: Upload coverage results to Coveralls
  env:
    COVERALLS_REPO_TOKEN: ${{ secrets.GITHUB_TOKEN }}
  run: |
    composer global require php-coveralls/php-coveralls
    php-coveralls --coverage_clover=build/logs/clover.xml -v

From local environment

If you would like to call Coveralls API from your local environment, you can set COVERALLS_RUN_LOCALLY environment variable. This configuration requires repo_token to specify which project on Coveralls your project maps to. This can be done by configuring .coveralls.yml or COVERALLS_REPO_TOKEN environment variable.

$ export COVERALLS_RUN_LOCALLY=1

# either env var
$ export COVERALLS_REPO_TOKEN=your_token

# or .coveralls.yml configuration
$ vi .coveralls.yml
repo_token: your_token # should be kept secret!

php-coveralls set the following properties to json_file which is sent to Coveralls API (same behaviour as the Ruby library will do except for the service name).

• service_name: php-coveralls
• service_event_type: manual

Parallel Builds

Coveralls provides the ability to combine coverage result from multiple parallel builds into one. To enable the feature you can set the following in your environment variable.

COVERALLS_PARALLEL=true

To distinguish your job name, please set the COVERALLS_FLAG_NAME environment variable.

COVERALLS_FLAG_NAME=$YOUR_PHP_VERSION

Bear in mind that you will need to configure your build to send a webhook after all the parallel builds are done in order for Coveralls to merge the results.

Refer to Parallel Builds Webhook for more information for setup on your environment.

CLI options

You can get help information for coveralls with the --help (-h) option.

php vendor/bin/php-coveralls --help

• --config (-c): Used to specify the path to .coveralls.yml. Default is .coveralls.yml
• --verbose (-v): Used to show logs.
• --dry-run: Used not to send json_file to Coveralls Jobs API.
• --exclude-no-stmt: Used to exclude source files that have no executable statements.
• --env (-e): Runtime environment name: test, dev, prod (default: "prod")
• --coverage_clover (-x): Coverage clover xml files(allowing multiple values)
• --json_path (-o): Used to specify where to output json_file that will be uploaded to Coveralls API. (default: build/logs/coveralls-upload.json)
• --root_dir (-r): Root directory of the project. (default: ".")

.coveralls.yml

php-coveralls can use optional .coveralls.yml file to configure options. This configuration file is usually at the root level of your repository, but you can specify other path by --config (or -c) CLI option. Following options are the same as Ruby library (see reference on coveralls.io).

• repo_token: Used to specify which project on Coveralls your project maps to. This is only needed for repos not using CI and should be kept secret
• service_name: Allows you to specify where Coveralls should look to find additional information about your builds. This can be any string, but using travis-ci or travis-pro will allow Coveralls to fetch branch data, comment on pull requests, and more.

Following options can be used for php-coveralls.

• entry_point: Used to specify API endpoint for sending reports. Useful when using self-hosted coveralls or other other, similar service (eg opencov). Default is https://coveralls.io.
• coverage_clover: Used to specify the path to clover.xml. Default is build/logs/clover.xml
• json_path: Used to specify where to output json_file that will be uploaded to Coveralls API. Default is build/logs/coveralls-upload.json.

# .coveralls.yml example configuration

# same as Ruby lib
repo_token: your_token # should be kept secret!
service_name: travis-pro # travis-ci or travis-pro

# for php-coveralls
coverage_clover: build/logs/clover.xml
json_path: build/logs/coveralls-upload.json

coverage clover configuration

You can specify multiple clover.xml logs at coverage_clover. This is useful for a project that has more than two test suites if all of the test results should be merged into one json_file.

#.coveralls.yml

# single file
coverage_clover: build/logs/clover.xml

# glob
coverage_clover: build/logs/clover-*.xml

# array
# specify files
coverage_clover:
  - build/logs/clover-Auth.xml
  - build/logs/clover-Db.xml
  - build/logs/clover-Validator.xml

You can also use --coverage_clover (or -x) command line option as follows:

coveralls --coverage_clover=build/logs/my-clover.xml

root_dir detection and override

This tool assume the current directory is the project root directory by default. You can override it with --root_dir command line option.
