Problem: win_split_ins has no check for E36 when moving an existing
window
Solution: check for room and fix the issues in f_win_splitmove()
(Sean Dewar)
0fd44a5ad8
Omit WSP_FORCE_ROOM, as it's not needed for Nvim's autocmd window, which is
floating. Shouldn't be difficult to port later if it's used for anything else.
Make win_splitmove continue working for turning floating windows into splits.
Move the logic for "unfloating" a float to win_split_ins; unlike splits, no
changes to the window layout are needed before calling it, as floats take no
room in the window layout and cannot affect the e_noroom check.
Add missing tp_curwin-fixing logic for turning external windows into splits, and
add a test.
NOTE: there are other issues with the way "tabpage independence" is implemented
for external windows; namely, some things assume that tp_curwin is indeed a
window within that tabpage, and as such, functions like tabpage_winnr and
nvim_tabpage_get_win currently don't always work for external windows (with the
latter aborting!)
Use last_status over frame_add_statusline, as Nvim's last_status already does
this for all windows in the current tabpage. Adjust restore_full_snapshot_rec to
handle this.
This "restore everything" approach is changed in a future commit anyway, so only
ensure it's robust enough to just pass tests.
Keep check_split_disallowed's current doc comment, as it's actually a bit more
accurate here. (I should probably PR Vim to use this one)
Allow f_win_splitmove to move a floating "wp" into a split; Nvim supports this.
Continue to disallow it from moving the autocommand window into a split (funnily
enough, the check wasn't reachable before, as moving a float was disallowed),
but now return -1 in that case (win_splitmove also returns FAIL for this, but
handling it in f_win_splitmove avoids us needing to switch windows first).
Cherry-pick Test_window_split_no_room fix from v9.1.0121.
Update nvim_win_set_config to handle win_split_ins failure in later commits.
This directory contains tests for various Vim features.
For testing an indent script see runtime/indent/testdir/README.txt.
If it makes sense, add a new test method to an already existing file. You may
want to separate it from other tests with comment lines.
TO ADD A NEW STYLE TEST:
1) Create a test_<subject>.vim file.
2) Add test_<subject>.res to NEW_TESTS_RES in Make_all.mak in alphabetical
order.
3) Also add an entry "test_<subject>" to NEW_TESTS in Make_all.mak.
4) Use make test_<subject> to run a single test.
At 2), instead of running the test separately, it can be included in
"test_alot". Do this for quick tests without side effects. The test runs a
bit faster, because Vim doesn't have to be started, one Vim instance runs many
tests.
At 4), to run a test in GUI, add "GUI_FLAG=-g" to the make command.
What you can use (see test_assert.vim for an example):
- Call assert_equal(), assert_true(), assert_false(), etc.
- Use assert_fails() to check for expected errors.
- Use try/catch to avoid an exception aborts the test.
- Use test_alloc_fail() to have memory allocation fail. This makes it possible
to check memory allocation failures are handled gracefully. You need to
change the source code to add an ID to the allocation. Add a new one to
alloc_id_T, before aid_last.
- Use test_override() to make Vim behave differently, e.g. if char_avail()
must return FALSE for a while. E.g. to trigger the CursorMovedI autocommand
event. See test_cursor_func.vim for an example.
- If the bug that is being tested isn't fixed yet, you can throw an exception
with "Skipped" so that it's clear this still needs work. E.g.: throw
"Skipped: Bug with <c-e> and popupmenu not fixed yet"
- The following environment variables are recognized and can be set to
influence the behavior of the test suite (see runtest.vim for details)
- $TEST_MAY_FAIL=Test_channel_one - ignore those failing tests
- $TEST_FILTER=Test_channel - only run test that match this pattern
- $TEST_SKIP_PAT=Test_channel - skip tests that match this pattern
- $TEST_NO_RETRY=yes - do not try to re-run failing tests
You can also set them in Vim:
:let $TEST_MAY_FAIL = 'Test_channel_one'
:let $TEST_FILTER = '_set_mode'
:let $TEST_SKIP_PAT = 'Test_loop_forever'
:let $TEST_NO_RETRY = 'yes'
Use an empty string to revert, e.g.:
:let $TEST_FILTER = ''
- See the start of runtest.vim for more help.
TO ADD A SCREEN DUMP TEST:
Mostly the same as writing a new style test. Additionally, see help on
"terminal-dumptest". Put the reference dump in "dumps/Test_func_name.dump".
OLD STYLE TESTS:
There are a few tests that are used when Vim was built without the +eval
feature. These cannot use the "assert" functions, therefore they consist of a
.in file that contains Normal mode commands between STARTTEST and ENDTEST.
They modify the file and the result gets written in the test.out file. This
is then compared with the .ok file. If they are equal the test passed. If
they differ the test failed.
RUNNING THE TESTS:
To run a single test from the src directory:
$ make test_<name>
The below commands should be run from the src/testdir directory.
To run a single test:
$ make test_<name>.res
The file 'messages' contains the messages generated by the test script. If a
test fails, then the test.log file contains the error messages. If all the
tests are successful, then this file will be an empty file.
- To run a single test function from a test script:
$ ../vim -u NONE -S runtest.vim <test_file>.vim <function_name>
- To execute only specific test functions, add a second argument:
$ ../vim -u NONE -S runtest.vim test_channel.vim open_delay
- To run all the tests:
$ make
- To run the test on MS-Windows using the MSVC nmake:
> nmake -f Make_dos.mak
- To run the tests with GUI Vim:
$ make GUI_FLAG=-g
or
$ make VIMPROG=../gvim
- To cleanup the temporary files after running the tests:
$ make clean
