Specifically, functions that are run in the context of the test runner are put in module `test/testutil.lua` while the functions that are run in the context of the test session are put in `test/functional/testnvim.lua`. Closes https://github.com/neovim/neovim/issues/27004.

-- Example: override the "tabline_update" UI event handler.
|
|
--
|
|
-- screen.lua defines default handlers for UI events, but tests
|
|
-- may sometimes want to override a handler.
|
|
|
|
-- The UI must declare that it wants to handle the UI events.
|
|
-- For this example, we enable `ext_tabline`:
|
|
screen:detach()
|
|
screen = Screen.new(25, 5)
|
|
screen:attach({ rgb = true, ext_tabline = true })
|
|
|
|
-- From ":help ui" we find that `tabline_update` receives `curtab` and
|
|
-- `tabs` objects. So we declare the UI handler like this:
|
|
local event_tabs, event_curtab
|
|
function screen:_handle_tabline_update(curtab, tabs)
|
|
event_curtab, event_tabs = curtab, tabs
|
|
end
|
|
|
|
-- Create a tabpage...
|
|
