Before:
  Save g:ale_linters, g:ale_linter_aliases

  let g:testlinter1 = {'name': 'testlinter1', 'executable': 'testlinter1', 'command': 'testlinter1', 'callback': 'testCB1', 'output_stream': 'stdout', 'read_buffer': 1, 'lint_file': 0, 'aliases': [], 'lsp': ''}

  call ale#linter#Reset()

After:
  Restore

  unlet! g:testlinter2

  let ale_linter_aliases = {'testft3': ['testft1', 'testft2']}

  AssertEqual [g:testlinter1, g:testlinter2], ale#linter#Get('testft3')
