So you are using the awesome Symfony4 Messenger component? Great. Now you would like to do some fancy unit and functional testing? Awesome!
We will show this by extending our Booking API example from before.
Parts
- Overview and simple demonstration of the Symfony Messenger
- (this article)
- …
What will we do here today?
- First we’ll show the components of a simple project to use the Symfony Messenger with
- then we will write one Unit test
- then one Functional one.
Run the project yourself if you like that kind of stuff
This is all done already in branch step3 of this repo:
git clone git@github.com:wuestkamp/symfony-messaging-queuing-example.gitcd symfony-messaging-queuing-example
git checkout step3
composer install
bin/console doctrine:schema:create
bin/console doctrine:fixtures:load -n
bin/console server:run# call the worker in a separate terminal
bin/console messenger:consume -vv# run unit tests
bin/phpunit
The simple booking workflow
What can this simple project do? It’s a booking api and can list and create bookings:
List Bookings
Call http://127.0.0.1:8000/bookings to see existing bookings, we’ll get some json returned. I use Postman to call the API but you can use curl or any browser too.
Create Booking
Call http://127.0.0.1:8000/bookings/create/new-booking to create a new booking, which will return:
The new booking was created instantly with a status of “new”.
