- Running out of retries, or unexpected screen state should make the
test FAIL, not ERROR.
- Uses levels to report the location of the caller.
- Improve message with retry-failure (formatting).
Before:
[ RUN ] test: 103.53 ms ERR
test/functional/helpers.lua:388:

To print the expect() call that would assert the current screen state, use
screen:snapshot_util(). In case of non-deterministic failures, use
screen:redraw_debug() to show all intermediate screen states.

PR #8221 took a short-cut when implementing the tests: screen.lua would
translate the linegrid highlight ids back into the old per-cell
attribute description.
Apart from cleaning up technical debt, this enables to check both rgb
and cterm colors in the same expect(), which previously was needlessly
restricted to ext_hlstate tests only.
For debugging failures like:
test/functional/helpers.lua:240: test/functional/ui/screen.lua:898:
bad argument #1 to 'unpack' (table expected, got number)
test/functional/helpers.lua:240: test/functional/ui/screen.lua:708:
attempt to index local 'item' (a number value)
ref #10804
Factor `get_snapshot()` out of `print_snapshot()`, so that callers can
get a table (for use with `expect()`) instead of the string form.
Try to use this to fix indeterminism in `searchhl_spec.lua`.
- Since the screen state is collected by `screen:expect_unchanged()`,
we don't need a deterministic initial state (which would then be
hardcoded into the test). This allows us to check "did anything
change in the last N ms?" rather than "did anything change compared
to a hardcoded screen-state?"
- This may end up fruitless, because `expect_unchanged()` depends on
timing to wait for an initial "current state".
ext_message doesn't set msg_col. Add a space and let client deal with
wrapping. When using silent redirect show the unwrapped message form.
Removed check is already part of msg_advance()
The test.functional.helpers and test.unit.helpers modules now include
all of the public functions from test.helpers, so there is no need to
separately require('test.helpers').
Why?
- Because we can.
- Because the TUI is just another GUI™
- Because it looks kinda nice, and provides useful context like 1 out of 100
times
Complies with "don't pay for what you don't use".
Some crashes for resizing were unfolded, add tests for those.
By historical accident, Nvim defaults to background=light. So on a dark
background, `:colorscheme default` looks completely wrong.
The "smart" logic that Vim uses is confusing for anyone who uses Vim on
multiple platforms, so rather than mimic that, pick the (hopefully) most
common default.
- Since Neovim is dark-powered, we assume most users have dark backgrounds.
- Most of the GUIs tend to have a dark background by default.
ref #6289
NB: existing `color default` test was actually enough to trigger the bug,
when ext_newgrid=false is used. I created the `:hi Normal` test as
I thought the builtin colors wouldn't set Normal (unless 'bg' is changed)
But as the root cause actually comes from `:hi Normal`, it makes sense
to still add the separate test (if `color default` here gets optimized to
become a no-op, or something).
