GraphQL is a query language for APIs. It was developed by Facebook and is often used as an alternative to REST APIs - but you can define the specific data you want to retrieve from the API. But how to test GraphQL with Codeception in PHP?

Spoiler: You do not need an extension.

Some years ago, I have used an existing random string generator for generating random unique strings. From one day to another, there were a lot of timeouts in the application.
It turned out that the random string generator was not as random as I thought.
Do you run automated tests against a random string generator if it can provide for sufficient randomness?
