使用Behat / Mink和Behat Laravel Extension测试多租户Laravel应用程序

Question

I am building a multi-tenant SaaS application which I am trying to write tests for with Behat, using Mink and the Behat Laravel Extension

When you register for an account, you get your own subdomain on the site {account}.tenancy.dev

my behat.yml file looks like so:

default:
    extensions:
        Laracasts\Behat:
            # env_path: .env.behat
        Behat\MinkExtension:
            default_session: laravel
            base_url: http://tenancy.dev
            laravel: ~

I am having problems straight off the bat as when I try to test my registration flow, I am getting a 404 error testing that the new subdomain is accessible, all of the data has been saved correctly, manually testing the process works and the subdomain routing works.

I was wondering if there was any way to do this using Behat and how I would go about setting Behat / Mink to use wildcard subdomains to test SaaS applications?

I am running the test inside the Homestead VM.

After a short while I revisited this problem and found a rather simple solution to be used in my FeatureContext.php:

$this->setMinkParameter('base_url', $url);

This changes the base url for any scenario it is used in:

/**
 * @Given I visit the url :url
 */
public function visitDomain($url)
{
    $this->setMinkParameter('base_url', $url);
    $this->visit('/');
}

Which is used in the following way:

Scenario: Test Multi Tenancy
  Given I have a business "mttest"
  When I visit the url "http://mttest.example.com"
  Then I should see "mttest"

Obviously this is slightly contrived but does show that what I was intending to do is possible.
