There's much more I could include here; check out [the LÖVE manual](https://love2d.org/wiki)

### writing tests
|
||||
|
||||
* `App.screen.init{width=.., height=..}` -- creates a fake screen for a test
|
||||
|
||||
* `App.screen.check(y, expected_contents, msg)` -- verifies text written to
|
||||
the fake screen at `y`. This isn't very realistic; `y` must exactly match
|
||||
what was displayed, and the expected contents show everything printed to
|
||||
that `y` in chronological order, regardless of `x` coordinate. In spite of
|
||||
these limitations, you can write lots of useful tests with this.
|
||||
|
||||
* `App.run_after_textinput(t)` -- mimics keystrokes resulting in `t` and then
|
||||
draws one frame.
|
||||
|
||||
* `App.run_after_keychord(chord)` -- mimics keystrokes resulting in `chord`
|
||||
and then draws one frame.
|
||||
|
||||
* `App.run_after_mouse_press(x,y, mouse_button)` -- mimics a mouse press down
|
||||
followed by drawing a frame.
|
||||
|
||||
* `App.run_after_mouse_release(x,y, mouse_button)` -- mimics a mouse release
|
||||
up followed by drawing a frame.
|
||||
|
||||
* `App.run_after_mouse_click(x,y, mouse_button)` -- mimics a mouse press down
|
||||
and mouse release up followed by drawing a frame.
|
||||
|
||||
* `App.wait_fake_time(t)` -- simulates the passage of time for `App.getTime()`.
