README
A PHP (7.4+) Behat context for Mailhog with Mink integration.
Allows to simulate link clicks in emails and continue from the links URL in Mink. Suitable in browser-email-browser flows such as forgotten password resets.
This context is based on the MailhogAwareContext
from rpkamp/mailhog-behat-extension.
Installation
This package does not require any specific HTTP client implementation, but it requires rpkamp/mailhog-client, which is based on HTTPlug, so you can inject your own HTTP client of choice. So you when you install this extension make sure you either already have an HTTP client installed, or install one at the same time as installing this context, otherwise installation will fail.
composer require rpkamp/mailhog-mink-behat-context <your-http-client-of-choice>
For more information please refer to the HTTPlug documentation for Library Users.
Usage
Register extension in Behat
This context require rpkamp/mailhog-behat-extension
to be enabled in your behat configuration.
If you have not already done so, add the MailhogExtension extension to your behat.yml
like so:
default: suites: # your suite configuration here extensions: rpkamp\Behat\MailhogExtension: base_url: http://localhost:8025
The base_url
is the URL where the Mailhog Web UI is listening to (by default this is http://localhost:8025
).
And also include the \rpkamp\Behat\MailhogExtension\Context\MinkAwareMailogContext
in your contexts for behat:
default: suites: contexts: - rpkamp\Behat\Context\MinkAwareMailhogContext
Note that this context does not extend rpkamp\Behat\MailhogExtension\Context\MailhogContext
from rpkamp/mailhog-behat-extension, so if you need functionality from both contexts you need to include both contexts in your behat configuration.
Gherkin steps
This context contains the following gherkin steps:
When I click the link "link-description" in the last received email When I click the link "link-description" in the opened email
This first step will fetch the last received email from Mailhog and search for a link with "link-description" as (in order):
- id attribute (<a id="link-description"></a>)
- link text (<a>link-description</a>)
- title attribute (<a title="link-description"></a>)
- alt attribute (<a alt="link-description"></a>)
- partial link text (<a>some link-description</a>)
It will stop when it finds any of the above criteria fits and that tell Mink to follow that link, so from there on you can continue in Mink. This enables scenarios like password reset where you receive an email, click a link in that email and then do something in a browser.
The second step fetches the email that was opened using rpkamp/mailhog-behat-extension and open the link with "link-description" in that, using the same procedure as outline above.
Run tests
Make sure you have Mailhog running and run:
make test
Running Mailhog for tests
You can either run your own instance of Mailhog or use the provided docker-compose file to run one for you. To run Mailhog with Docker make sure you have Docker and docker-compose installed and run:
docker-compose up -d
Mailhog ports for tests
To prevent port collisions with any other Mailhog instances while testing the tests expect Mailhog to listen to SMTP on port 4025 (instead of the default 1025) and to HTTP traffic on port 11025 (instead of the default 8025).
