patch 8.2.0195: some tests fail when run in the GUI Commit: https://github.com/vim/vim/commit/3180fe6c6dc0728d21c6318b957022b029c234f0 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Feb 2 13:47:06 2020 +0100 patch 8.2.0195: some tests fail when run in the GUI Problem: Some tests fail when run in the GUI. Solution: Make sure the window width is enough. In the GUI run terminal Vim in the terminal, if possible.

" Settings for test script execution
" Always use "sh", don't use the value of "$SHELL".
set shell=sh

" Only when the +eval feature is present. 
if 1
  " While some tests overwrite $HOME to prevent them from polluting user files,
  " we need to remember the original value so that we can tell external systems
  " where to ask about their own user settings.
  let g:tester_HOME = $HOME
endif
