Fusio provides a complete Test-Setup for your API endpoints. For the test case
we use an in-memory sqlite database which contains the schema defined in the
resources/migration folder. In the Fixture.php class it is also possible to
define fixture data which is inserted for every test case.
The idea is that each endpoint has a corresponding test case class which tests the GET, POST, PUT and DELETE method of the resource. Internally we can send an HTTP request to Fusio without the need to setup an HTTP server this in combination with the in-memory sqlite database makes these tests very fast and efficient.
