Laravel Dusk Visual Assert
==========================

[](#laravel-dusk-visual-assert)

This package adds assertions to compare screenshots taken during [Laravel Dusk](https://laravel.com/docs/10.x/dusk#taking-a-screenshot) tests using the Imagick extension.

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

[](#installation)

You can install the package via composer:

```
composer require --dev rossjcooper/laravel-dusk-visual-assert
```

Configuration
-------------

[](#configuration)

Publish the config file to control default settings:

```
php artisan vendor:publish --tag=visual-assert-config
```

Usage
-----

[](#usage)

The Dusk Browser class now has access to some new methods:

### assertScreenshot()

[](#assertscreenshot)

This method will take a screenshot of the current page and compare it to a reference image (generated the first time the test is run).

If the images are different, the test will fail and save the image diff so you can inspect the differences.

```
$browser->assertScreenshot(string $name, float|null $threshold = null, int|null $metric = null)
```

Example:

```
$this->browse(function (Browser $browser) {
        $browser->visit('/')
            ->assertScreenshot('home');
    });
```

### assertResponsiveScreenshots()

[](#assertresponsivescreenshots)

This method is similar to the `assertScreenshot` as above but it screenshots the page at different screen sizes.

```
$browser->assertResponsiveScreenshots(string $name, float|null $threshold = null, int|null $metric = null)
```

Example:

```
$this->browse(function (Browser $browser) {
        $browser->visit('/')
            ->assertResponsiveScreenshots('home');
    });
```

Updating reference images
-------------------------

[](#updating-reference-images)

If you want to update the reference images simply delete them from the `tests/Browser/screenshots/references` directory and re-run your tests to generate new ones.

I would recommend committing the reference images to your repository so you can track changes to them over time.

Caveats
-------

[](#caveats)

When comparing images, the package will expect the screenshots to be the same width and height as the reference images.

```
Error: Screenshots are not the same size, ensure the screenshots are taken using the same Dusk environment.
Failed asserting that false is true.

```

If the Dusk environment has changed (headless-mode, window size, etc) then the comparison screenshots could be different sizes and the assertion will fail.

You can change the `skip_if_different_window_size` config option to overcome this if you need to use a different Dusk environment temporarily.
