[v5] Events not handled in functional tests

[juni0r]

I'm testing an API endpoint for signing up users. I used to send a confirmation email from the controller method and I could assert that it was sent using Mailer.fake().

However, when I moved the email sending in an event handler, it is not being invoked during testing. When I use Event.fake() in the test the event does show up but without faking, it'll never get handled.

// in the controller
class UsersController {
  public async signup({ request, response }: HttpContextContract) {
    // ...
    await Event.emit('user:signup', user)
    // ...
  }
}

// event handler in /start/events.js
Event.on('user:signup', async (user: User) => {
  const emailConfirmation = await EmailConfirmation.createFor(user)
  await new EmailConfirmationMailer(emailConfirmation).sendLater()
})

Everything works fine, when testing manually through the dev server. What am I missing?
