# PHPUnit

PHPUnit is a programmer-oriented testing framework for PHP.
It is an instance of the xUnit architecture for unit testing frameworks.

## Installation

We distribute a [PHP Archive (PHAR)](https://php.net/phar) that has all required dependencies of PHPUnit bundled in a single file:

```bash
$ wget https://phar.phpunit.de/phpunit-X.Y.phar

$ php phpunit-X.Y.phar --version
```

Please replace `X.Y` with the version of PHPUnit you are interested in.

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?ref=github) for details on how to install PHPUnit.
