## 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.
