MutaTesting
===========

[](#mutatesting)

Mutation testing tool for PHP.

[![Build Status](https://camo.githubusercontent.com/37c76c3c50a5fcc6a76659f93c2ee6e83b0620f7453d85b189b1479e187730bd/68747470733a2f2f7365637572652e7472617669732d63692e6f72672f48616c6c65636b34352f4d75746154657374696e672e706e67)](http://travis-ci.org/Halleck45/MutaTesting)[![Latest Stable Version](https://camo.githubusercontent.com/01520fd53bc36f9197f6ec7f211e114c3c1d839b49f67940edecb32826770100/68747470733a2f2f706f7365722e707567782e6f72672f68616c6c65636b34352f6d75746174657374696e672f762f737461626c652e706e67)](https://packagist.org/packages/halleck45/mutatesting)

According to [Wikipedia](http://en.wikipedia.org/wiki/Mutation_testing):

> Mutation testing (or Mutation analysis or Program mutation) evaluates the quality of software tests. Mutation testing involves modifying a program's source code or byte code in small ways.

MutaTesting supports [PHPUnit](http://phpunit.de/manual/current/en/index.html) and [atoum](http://docs.atoum.org/). You can create an adapter for any PHP testing framework.

\## Requirements

You only need PHP 5.3 . No specific PHP extension is required...

Installation
------------

[](#installation)

\### As phar archive

Simply download the [phar archive](build/mutatesting.phar) and run the following command :

```
php mutatesting.phar {tool} {binary}  {test directory}

```

### With Composer

[](#with-composer)

Edit your `composer.json`:

```
"require": {
    "halleck45/mutatesting" : "@dev"
}
```

And run Composer:

```
php composer.phar update halleck45/mutaTesting
```

Usage
-----

[](#usage)

```
./bin/mutatesting {tool} {binary}  {test directory}
```

Example for PHPUnit:

```
./bin/mutatesting phpunit phpunit.phar myTestFolder
```

Example for atoum:

```
./bin/mutatesting atoum mageekguy.atoum.phar myTestFolder
```

Note that you don't need to use the `-d` or `-f` option with atoum...

### Advanced usage

[](#advanced-usage)

#### Strategy

[](#strategy)

In order to avoid to have too much mutants, MutaTesting uses [PhpMetrics](https://github.com/Halleck45/PhpMetrics) in order to estimate number of bugs in each tested file, and focuses only on files that contain more anomalies.

You can use the `--bugs` option to define the limit to use.

For example, `--bugs=".6"` means that mutants are preserved only if there is at least 0.6 estimated bugs in the tested file.

#### Formatters

[](#formatters)

To have a html report file, tou need to use the `--report-html` option.

```
./bin/mutatesting {tool} {binary} {test directory} --report-html=/tmp/file.html
```

#### Testing options

[](#testing-options)

If your tests need options, you can pass them with `--options`

```
./bin/mutatesting phpunit phpunit.phar  myTestFolder --options="-c phpunit.xml"
```

\#### Parallelization

You can change the number of parallelized tests with the `processes` options :

```
./bin/mutatesting {tool} {binary} {test directory} --processes=10
```

\#### Performance

MutaTesting is very slow : your unit tests will be runned as many times as there are mutant. In order to increase performance, a cache file is created in `/tmp/muta-cache.php`.
