Testing storages in a more generic way.

[anonrig]

A generic solution to testing and enforcing tests for separate storage units can be found.

Proposed solution is:

After initialization of the controller:

var controller = Botkit.slackbot({
  storage: my_storage_provider
})

Botkit.slackbot constructor can automatically test the storage tests and if test fails, we prompt a message to user and terminate the botkit process.

If --force is used, we skip the test and run the application without any testing.

Cool! We'd have to make sure to test the storage in a way which doesn't effect the storage. Because folks might have sensitive data in there or triggers for changes like Firebase has. So this might not be desirable.

[anonrig]

We should mock the storage functionality and not test it using the config given to the botkit.

You could just inspect the interface and make sure all required methods are present. I don't think there's much you can do beyond that without writing/fetching data. I agree with @RafaelCosman that you wouldn't want to do that as part of a test.

This could be considered as part of #850
