Before:
  Save g:ale_c_cppcheck_executable
  Save g:ale_c_cppcheck_options

  unlet! g:ale_c_cppcheck_executable
  unlet! b:ale_c_cppcheck_executable

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

After:
  Restore
  unlet! b:command_tail
  unlet! b:ale_c_cppcheck_executable
  unlet! b:ale_c_cppcheck_options
  call ale#linter#Reset()
  call ale#test#RestoreDirectory()

Execute(The executable should be configurable):

  let b:ale_c_cppcheck_executable = 'foobar'

  AssertEqual 'foobar', ale_linters#c#cppcheck#GetExecutable(bufnr(''))

Execute(The executable should be used in the command):
  AssertEqual
  \ ale#Escape('cppcheck') . b:command_tail,

  let b:ale_c_cppcheck_executable = 'foobar'

  AssertEqual
  \ ale#Escape('foobar') . b:command_tail,
  \ ale_linters#c#cppcheck#GetCommand(bufnr(''))

Execute(cppcheck for C++ should detect compile_commands.json files):
  call ale#test#SetFilename('cppcheck_paths/one/foo.cpp')

  AssertEqual
