This adds an interface for mail drivers to implement, defining several
methods that we need throughout Flarum to configure, validate and use
the various email drivers we can support through Laravel.
More mail drivers can be added by `extend()`ing the container binding
"mail.supported_drivers" with an arbitrary key and the name of a class
that implements our new `DriverInterface`.
This will ensure that drivers added by extensions can be properly built
and validated, even in the frontend.
Refactored to use the Capsule Database manager for setting up the
Flarum (mysql) connection.
This will introduce the reconnector automatically, fixing #1740
This creates a dedicated test suite for integration tests. All of them
can be run independently, and there is no order dependency - previously,
all integration tests needed the installer test to run first, and they
would fail if installation failed.
Now, the developer will have to set up a Flarum database to be used by
these tests. A setup script to make this simple will be added in the
next commit.
Small tradeoff: the installer is NOT tested in our test suite anymore,
only implicitly through the setup script. If we decide that this is a
problem, we can still set up separate, dedicated installer tests which
should probably test the web installer.
Since this is not strictly speaking a domain invariant, but rather
specific to the user interface where passwords are not displayed, and
should therefore be entered twice to prevent mistakes going unnoticed,
this stuff should be checked in the frontend, not in the install steps.
Next step: Ensure that all domain-specific validation is done in the
installer's domain layer. This will ensure these validations cannot be
forgotten, and keep the frontends DRY.
Since we do not provide a development VM anymore, it does not make sense
to have "default" credentials etc.
To reproduce something similar, I'd suggest using a YAML or JSON file
together with the `--file` option.
