commit https://github.com/vim/vim/commit/46c4d4ac66aa2b129f4dcec9debfda606f72d4b3 Author: Bram Moolenaar <Bram@vim.org> Date: Fri Aug 5 19:31:57 2016 +0200 patch 7.4.2157 Problem: Test_job_start_fails() is expected to report memory leaks, making it hard to see other leaks in test_partial. Solution: Move Test_job_start_fails() to a separate test file.

" Common preparations for running tests.

" Make sure 'runtimepath' does not include $HOME.
set rtp=$VIM/vimfiles,$VIMRUNTIME,$VIM/vimfiles/after

" Only when the +eval feature is present. 
if 1
  " Make sure $HOME does not get read or written.
  let $HOME = '/does/not/exist'
