+# PHP_CodeCoverage
+
+**PHP_CodeCoverage** is a library that provides collection, processing, and rendering functionality for PHP code coverage information.
+
+## Requirements
+
+PHP 5.6 is required but using the latest version of PHP is highly recommended.
+
+### PHP 5
+
+[Xdebug](http://xdebug.org/) is the only source of raw code coverage data supported for PHP 5. Version 2.2.1 of Xdebug is required but using the latest version is highly recommended.
+
+### PHP 7
+
+Version 2.4.0 (or later) of [Xdebug](http://xdebug.org/) as well as [phpdbg](http://phpdbg.com/docs) are supported sources of raw code coverage data for PHP 7.
+
+### HHVM
+
+A version of HHVM that implements the Xdebug API for code coverage (`xdebug_*_code_coverage()`) is required.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require phpunit/php-code-coverage
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev phpunit/php-code-coverage
+
+## Using the PHP_CodeCoverage API
+
+```php
+<?php
+$coverage = new \SebastianBergmann\CodeCoverage\CodeCoverage;
+$coverage->start('<name of test>');
+
+// ...
+
+$coverage->stop();
+
+$writer = new \SebastianBergmann\CodeCoverage\Report\Clover;
+$writer->process($coverage, '/tmp/clover.xml');
+
+$writer = new \SebastianBergmann\CodeCoverage\Report\Html\Facade;
+$writer->process($coverage, '/tmp/code-coverage-report');

+To add this package as a local, per-project dependency to your project, simply add a dependency on `phpunit/php-text-template` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on Text_Template:
+
+    {
+        "require": {
+            "phpunit/php-text-template": "~1.2"
+        }

+
+# PHP_Timer
+
+Utility class for timing things, factored out of PHPUnit into a stand-alone component.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require phpunit/php-timer
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev phpunit/php-timer
+
+## Usage
+
+### Basic Timing
+
+```php
+PHP_Timer::start();
+
+// ...
+
+$time = PHP_Timer::stop();
+var_dump($time);
+
+print PHP_Timer::secondsToTimeString($time);
+```
+
+The code above yields the output below:
+
+    double(1.0967254638672E-5)
+    0 ms
+
+### Resource Consumption Since PHP Startup
+
+```php
+print PHP_Timer::resourceUsage();
+```
+
+The code above yields the output below:
+
+    Time: 0 ms, Memory: 0.50MB

+# PHPUnit_MockObject
+
+**PHPUnit_MockObject** is the default mock object library for PHPUnit.
+
+## Requirements
+
+* PHP 5.6 is required but using the latest version of PHP is highly recommended
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require phpunit/phpunit-mock-objects
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev phpunit/phpunit-mock-objects
+

+# Contributor Code of Conduct
+
+As contributors and maintainers of this project, and in the interest of fostering an open and welcoming community, we pledge to respect all people who contribute through reporting issues, posting feature requests, updating documentation, submitting pull requests or patches, and other activities.
+
+We are committed to making participation in this project a harassment-free experience for everyone, regardless of level of experience, gender, gender identity and expression, sexual orientation, disability, personal appearance, body size, race, ethnicity, age, religion, or nationality.
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery
+* Personal attacks
+* Trolling or insulting/derogatory comments
+* Public or private harassment
+* Publishing other's private information, such as physical or electronic
+  addresses, without explicit permission
+* Other unethical or unprofessional conduct
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+By adopting this Code of Conduct, project maintainers commit themselves to fairly and consistently applying these principles to every aspect of managing this project. Project maintainers who do not follow or enforce the Code of Conduct may be permanently removed from the project team.
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community.
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project maintainer at sebastian@phpunit.de. All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. Maintainers are obligated to maintain confidentiality with regard to the reporter of an incident.
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.3.0, available at [http://contributor-covenant.org/version/1/3/0/][version]

+# Contributing to PHPUnit
+
+## Contributor Code of Conduct
+
+Please note that this project is released with a [Contributor Code of Conduct](CODE_OF_CONDUCT.md). By participating in this project you agree to abide by its terms.
+
+## Workflow
+
+* Fork the project.
+* Make your bug fix or feature addition.
+* Add tests for it. This is important so we don't break it in a future version unintentionally.
+* Send a pull request. Bonus points for topic branches.
+
+Please make sure that you have [set up your user name and email address](http://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup) for use with Git. Strings such as `silly nick name <root@localhost>` look really stupid in the commit history of a project.
+
+Pull requests for bug fixes must be based on the current stable branch whereas pull requests for new features must be based on the `master` branch.
+
+We are trying to keep backwards compatibility breaks in PHPUnit to an absolute minimum. Please take this into account when proposing changes.
+
+Due to time constraints, we are not always able to respond as quickly as we would like. Please do not take delays personal and feel free to remind us if you feel that we forgot to respond.
+
+## Coding Guidelines
+
+This project comes with a configuration file for [php-cs-fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer) (`.php_cs`) that you can use to (re)format your sourcecode for compliance with this project's coding guidelines:
+
+```bash
+$ wget http://cs.sensiolabs.org/download/php-cs-fixer-v2.phar -O php-cs-fixer.phar
+
+$ php php-cs-fixer.phar fix
+```
+
+## Using PHPUnit from a Git checkout
+
+The following commands can be used to perform the initial checkout of PHPUnit:
+
+```bash
+$ git clone git://github.com/sebastianbergmann/phpunit.git
+
+$ cd phpunit
+```
+
+Retrieve PHPUnit's dependencies using [Composer](https://getcomposer.org/):
+
+```bash
+$ composer install
+```
+
+The `phpunit` script can be used to invoke the PHPUnit test runner:
+
+```bash
+$ ./phpunit --version
+```
+
+## Running PHPUnit's own test suite
+
+After following the steps shown above, PHPUnit's own test suite is run like this:
+
+```bash
+$ ./phpunit
+```
+
+## Reporting issues
+
+Please use the most specific issue tracker to search for existing tickets and to open new tickets:
+
+* [General problems](https://github.com/sebastianbergmann/phpunit/issues)
+* [Code Coverage](https://github.com/sebastianbergmann/php-code-coverage/issues)
+* [Stub and Mock Objects](https://github.com/sebastianbergmann/phpunit-mock-objects/issues)
+* [DbUnit](https://github.com/sebastianbergmann/dbunit/issues)
+* [Documentation](https://github.com/sebastianbergmann/phpunit-documentation/issues)
+* [Website](https://github.com/sebastianbergmann/phpunit-website/issues)

+# PHPUnit
+
+PHPUnit is a programmer-oriented testing framework for PHP. It is an instance of the xUnit architecture for unit testing frameworks.
+
+[![Latest Stable Version](https://img.shields.io/packagist/v/phpunit/phpunit.svg?style=flat-square)](https://packagist.org/packages/phpunit/phpunit)
+[![Minimum PHP Version](https://img.shields.io/badge/php-%3E%3D%205.6-8892BF.svg?style=flat-square)](https://php.net/)
+[![Build Status](https://img.shields.io/travis/sebastianbergmann/phpunit/5.7.svg?style=flat-square)](https://phpunit.de/build-status.html)
+
+## Installation
+
+We distribute a [PHP Archive (PHAR)](https://php.net/phar) that has all required (as well as some optional) dependencies of PHPUnit bundled in a single file:
+
+```bash
+$ wget https://phar.phpunit.de/phpunit.phar
+
+$ chmod +x phpunit.phar
+
+$ mv phpunit.phar /usr/local/bin/phpunit
+```
+
+You can also immediately use the PHAR after you have downloaded it, of course:
+
+```bash
+$ wget https://phar.phpunit.de/phpunit.phar
+
+$ php phpunit.phar
+```
+
+Alternatively, you may use [Composer](https://getcomposer.org/) to download and install PHPUnit as well as its dependencies. Please refer to the [documentation](https://phpunit.de/documentation.html) for details on how to do this.
+

+ * A TestCase defines the fixture to run multiple tests.
+ *
+ * To define a TestCase
+ *
+ *   1) Implement a subclass of PHPUnit_Framework_TestCase.
+ *   2) Define instance variables that store the state of the fixture.
+ *   3) Initialize the fixture state by overriding setUp().
+ *   4) Clean-up after a test by overriding tearDown().
+ *
+ * Each test runs in its own fixture so there can be no side effects
+ * among test runs.
+ *
+ * Here is an example:
+ *
+ * <code>
+ * <?php
+ * class MathTest extends PHPUnit_Framework_TestCase
+ * {
+ *     public $value1;
+ *     public $value2;
+ *
+ *     protected function setUp()
