API Testing Documentation?

[simonjcarr]

Is there any documentation for API testing. I'm not sure if the functional testing is only for full stack Adonis apps.
When it comes to unit testing, I can't find anything relating to testing controller methods. Am I better creating a service and calling those service methods from the controller, but I can't find any docs relating to controller/service design, so I assume your supposed to test API controllers directly??

I feel like I am getting a bit further, by just experimenting. I have found some docs at https://docs.adonisjs.com/guides/testing/http-tests
With just some a very simple example, I am getting an error about suite is not configured.
Here is my test

import { test } from '@japa/runner'

test.group('Users list', () => {
  test('example test', async ({ assert, client }) => {
    const response = await client.get('/')
    response.assertStatus(200)
  })
})

I get the error

[ info ] booting application to run tests...

   Error: Cannot apply suites filter. "tests/functional/users/list.spec.ts" suite is not configured
