behat-code-coverage

behat-code-coverage is a Behat extension that generates Code Coverage reports for Behat tests.

Generating Code Coverage reports allows you to to analyze which parts of your codebase are tested and how well. However, Code Coverage alone should NOT be used as a single metric defining how good your tests are.

Note! This is a maintained fork of vipsoft/code-coverage-extension, including codebase for vipsoft/code-coverage-common package with compatible version numbers for stable releases.

Requirements

• PHP 5.6+ / 7.0+
• Behat v3
• Xdebug or phpdbg extension enabled

Change Log

Please see CHANGELOG.md for information on recent changes.

Install

Install this package as a development dependency in your project:

$ composer require --dev leanphp/behat-code-coverage

Enable extension by editing behat.yml of your project:

default:
  extensions:
    LeanPHP\Behat\CodeCoverage\Extension:
      drivers:
        - local
      filter:
        whitelist:
          include:
            directories:
              'src': ~
      report:
        format:   html
        options:
          target: build/behat-coverage

This will sufficient to enable Code Coverage generation in html format in build/behat-coverage directory. This extension supports various Configuration options. For a fully annotated example configuration file check Configuration section.

Usage

If you execute bin/behat command, you will see code coverage generated in target (i.e. build/behat-coverage) directory (in html format):

$ bin/behat

Running with phpdbg

This extension now supports phpdbg, which results in faster execution when using more recent versions of PHP. Run phpspec via phpdbg:

$ phpdbg -qrr bin/behat run

Configuration

You can see fully annotated behat.yml example file below, which can be used as a starting point to further customize the defaults of the extension. The configuration file below has all of the [Configuration Options](#Configuration Options).
