Before:
  Save g:ale_rust_rls_executable
  Save g:ale_rust_rls_toolchain

  unlet! g:ale_rust_rls_executable
  unlet! g:ale_rust_rls_toolchain

  runtime ale_linters/rust/rls.vim

  call ale#test#SetDirectory('/testplugin/test/command_callback')

After:
  Restore

  call ale#test#RestoreDirectory()
  call ale#linter#Reset()

Execute(The default executable path should be correct):
  AssertEqual 'rls', ale_linters#rust#rls#GetExecutable(bufnr(''))
  AssertEqual
  \ ale#Escape('rls') . ' +' . ale#Escape('nightly'),
  \ ale_linters#rust#rls#GetCommand(bufnr(''))

Execute(The toolchain should be configurable):
  let g:ale_rust_rls_toolchain = 'stable'

  AssertEqual
  \ ale#Escape('rls') . ' +' . ale#Escape('stable'),
  \ ale_linters#rust#rls#GetCommand(bufnr(''))

Execute(The toolchain should be ommitted if not given):
  let g:ale_rust_rls_toolchain = ''

  AssertEqual
  \ ale#Escape('rls'),
  \ ale_linters#rust#rls#GetCommand(bufnr(''))

Execute(The project root should be detected correctly):
  AssertEqual '', ale_linters#rust#rls#GetProjectRoot(bufnr(''))

  call ale#test#SetFilename('rust-rls-project/test.rs')

  AssertEqual
  \ ale#path#Simplify(g:dir . '/rust-rls-project'),
