Just in time for the new snapshot cycle, which is rumored to start this week. These tests will ensure that the next Minecraft update can't break WI Zoom without me noticing. The zoom, the keybind, the translations, past bugs, everything is included in these tests. It's the first of my mods to achieve full test coverage.
And now that all three of the mods that I update to every snapshot (Wurst, Mo Glass, WI Zoom) have at least a basic end-to-end test set up, that makes it theoretically impossible for me to release a snapshot build that won't at least let you launch the game and enter a singleplayer world without crashing.
