PDFUnit
=======

[](#pdfunit)

An extension to PHPUnit to test creation of PDF-Files.

About
-----

[](#about)

Creating PDF-Files is always a bit difficult as the best comparison is a visual one.

As 2 PDF-Files can be internally completely different there is no way of comparing them on a source-code-level. Therefore comparing them by creating an image and comparing that to a known-good file. The differences between the two files are calculated and measured against a threshold.

Requirements
------------

[](#requirements)

This package requires imagemagicks `compare`-binary to be installed and available in the path.

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

[](#installation)

```
$ composer require org_heigl/pdfunit

```

Usage
-----

[](#usage)

```
namespace Acme;

use Org_Heigl\PDFUnit\TestCase;

class PDFTest extends TestCase
{
    public function testPdf()
    {
        $this->assertPdfDiffBelowThreshold(
            'known-good.pdf',
            0.4,
            'generated.pdf'
        );
    }
}

```

This will compare `generated.pdf` agains `known-good.pdf` and checks whether the difference is less or equals to 0.4.
