Provides collection, processing, and rendering functionality for PHP code coverage information.

## 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
```

## Usage

```php
<?php declare(strict_types=1);
use SebastianBergmann\CodeCoverage\Filter;
use SebastianBergmann\CodeCoverage\Driver\Selector;
use SebastianBergmann\CodeCoverage\CodeCoverage;
use SebastianBergmann\CodeCoverage\Report\Html\Facade as HtmlReport;

$filter = new Filter;

$filter->includeFiles(
    [
        '/path/to/file.php',
        '/path/to/another_file.php',
    ]
);

$coverage = new CodeCoverage(
    (new Selector)->forLineCoverage($filter),
    $filter
);

$coverage->start('<name of test>');

// ...

$coverage->stop();

(new HtmlReport)->process($coverage, '/tmp/code-coverage-report');
```
