-- This file is intended for in-game testing. The file provides functions
-- for quickly populating the addon instance with test data, which then
-- can be used to manually verify mainly the behavior of the GUI, but also
-- the system in its real environment.
--
-- When possible, tests should instead be automated in UnitTest.lua.


--[[

# Release tests:
1. Perform all other tests.

# Before push to master:
1. Unit tests must pass: UnitTests.lua
2. For any changed module, perform relevant tests.
3. Manually check that happy path and relevant edge cases work.

#--------------------------------------------------------------------------------

# Communication tests:
1. Request timer via GUI. Check that chat message appears.
2. Share timer with other player via button. Check that they receive it.

# GUI tests:
1. Go to non-boss zone and run StartTimers25. Check that GUI looks OK and that
   you don't get any alerts. Change options arbitrarily and check that GUI
   looks OK.
      a. Repeat in boss zone. Check that you get alerts.
2. After (1.):
      a. /reload and check that everything looks OK.
      b. Relog and check that everything looks OK.
3. Click all buttons exploratorily. Check that nothing breaks.

# Backend tests
1. Run StartTimers25. Check that GUI behaves as expected. 

# Logger tests
1. Clear all timers. Enter the perimiter of some boss and try to share. Check
   that Info message looks OK.
2. Run StartTimers4 and let it expire. Enter the perimiter of some boss and try
   to share. Check that Info message looks OK.

# CLI tests
1. Set log level to 'Nothing' via CLI. Check that GUI options shows correct
   value. Repeat Logger tests and verify that nothing is printed.
2. Set log level to 'Info' via CLI. Repeat (1.) but now check that the logger
   tests actually pass.
