## Intro
Setting up Laravel Dusk tests to run with Laradock appears be something that
eludes most Laradock users. This guide is designed to show you how to wire them
up to work together. This guide is written with macOS and Linux in mind. As such,
it's only been tested on macOS. Feel free to create pull requests to update the guide
for Windows-specific instructions.
This guide assumes you know how to use a DNS forwarder such as `dnsmasq` or are comfortable
with editing the `/etc/hosts` file for one-off DNS changes.
<a name="dns-setup"></a>
## DNS Setup
According to RFC-2606, only four TLDs are reserved for local testing[^1]:
- `.test`
- `.example`
- `.invalid`
- `.localhost`
A common TLD used for local development is `.dev`, but newer versions of Google
Chrome (such as the one bundled with the Selenium Docker image), will fail to
resolve that DNS as there will appear to be a name collision.
The recommended extension is `.test` for your Laravel web apps because you're
running tests. Using a DNS forwarder such as `dnsmasq` or by editing the `/etc/hosts`
file, configure the host to point to `localhost`.
For example, in your `/etc/hosts` file:
```
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
127.0.0.1 myapp.test
```
This will ensure that when navigating to `myapp.test`, it will route the
request to `127.0.0.1` which will be handled by Nginx in Laradock.
<a name="docker-compose"></a>
## Docker Compose setup
In order to make the Selenium container talk to the Nginx container appropriately,
the `docker-compose.yml` needs to be edited to accommodate this. Make the following
changes:
```yaml
...
selenium:
...
depends_on:
- nginx
links:
- nginx:<your_domain>
```
This allows network communication between the Nginx and Selenium containers
and it also ensures that when starting the Selenium container, the Nginx
container starts up first unless it's already running. This allows
the Selenium container to make requests to the Nginx container, which is
necessary for running Dusk tests. These changes also link the `nginx` environment
variable to the domain you wired up in your hosts file.

## Laravel Dusk Setup
In order to make Laravel Dusk make the proper request to the Selenium container,
you have to edit the `DuskTestCase.php` file that's provided on the initial
installation of Laravel Dusk. The change you have to make deals with the URL the
Remote Web Driver attempts to use to set up the Selenium session.
One recommendation for this is to add a separate config option in your `.env.dusk.local`
so it's still possible to run your Dusk tests locally should you want to.
### .env.dusk.local
```
...
USE_SELENIUM=true
```
### DuskTestCase.php
```php
abstract class DuskTestCase extends BaseTestCase
{
...
protected function driver()
{
if (env('USE_SELENIUM', 'false') == 'true') {
return RemoteWebDriver::create(
'http://selenium:4444/wd/hub', DesiredCapabilities::chrome()
);
} else {
return RemoteWebDriver::create(
'http://localhost:9515', DesiredCapabilities::chrome()
);
}
}
}
```

## Running Laravel Dusk Tests
Now that you have everything set up, to run your Dusk tests, you have to SSH
into the workspace container as you normally would:
```docker-compose exec --user=laradock workspace bash```
Once inside, you can change directory to your application and run:
```php artisan dusk```
One way to make this easier from your project is to create a helper script. Here's one such example:
```bash
#!/usr/bin/env sh
LARADOCK_HOME="path/to/laradock"
pushd ${LARADOCK_HOME}
docker-compose exec --user=laradock workspace bash -c "cd my-project && php artisan dusk && exit"
```
This invokes the Dusk command from inside the workspace container but when the script completes
execution, it returns your session to your project directory.
