Before:
  Save g:ale_c_parse_makefile
  let g:ale_c_parse_makefile = 0

  call ale#assert#SetUpLinterTest('cpp', 'clangtidy')
  call ale#test#SetFilename('test.cpp')

After:
  call ale#assert#TearDownLinterTest()

Execute(The clangtidy command default should be correct):
  AssertLinter 'clang-tidy',
  \ ale#Escape('clang-tidy') . ' %s'

Execute(You should be able to remove the -checks option for clang-tidy):
  let b:ale_cpp_clangtidy_checks = []

  AssertLinter 'clang-tidy',
  \ ale#Escape('clang-tidy') . ' %s'

Execute(You should be able to set other checks for clang-tidy):
  let b:ale_cpp_clangtidy_checks = ['-*', 'clang-analyzer-*']

  AssertLinter 'clang-tidy',
  \ ale#Escape('clang-tidy')
  \   . ' -checks=' . ale#Escape('-*,clang-analyzer-*') . ' %s'

Execute(You should be able to manually set compiler flags for clang-tidy):
  let b:ale_cpp_clangtidy_checks = ['*']
  let b:ale_cpp_clangtidy_options = '-Wall'

  AssertLinter 'clang-tidy',
  \ ale#Escape('clang-tidy') . ' -checks=' . ale#Escape('*') . ' %s -- -Wall'

Execute(You should be able to manually set flags for clang-tidy):
  let b:ale_cpp_clangtidy_extra_options = '-config='

  AssertLinter 'clang-tidy',
  \ ale#Escape('clang-tidy') . ' ' . ale#Escape('-config=') . ' %s'

Execute(The build directory should be configurable):
  let b:ale_cpp_clangtidy_checks = ['*']
  let b:ale_c_build_dir = '/foo/bar'

  AssertLinter 'clang-tidy',
  \ ale#Escape('clang-tidy')
  \   . ' -checks=' . ale#Escape('*') . ' %s'
  \   . ' -p ' . ale#Escape('/foo/bar')

Execute(The build directory setting should override the options):
  let b:ale_cpp_clangtidy_checks = ['*']
  let b:ale_c_build_dir = '/foo/bar'
  let b:ale_cpp_clangtidy_options = '-Wall'

  AssertLinter 'clang-tidy',
  \ ale#Escape('clang-tidy')
  \   . ' -checks=' . ale#Escape('*') . ' %s'
  \   . ' -p ' . ale#Escape('/foo/bar')

Execute(The build directory should be used for header files):
  call ale#test#SetFilename('test.h')

  let b:ale_cpp_clangtidy_checks = ['*']
  let b:ale_c_build_dir = '/foo/bar'
  let b:ale_cpp_clangtidy_options = '-Wall'

  AssertLinter 'clang-tidy',
  \ ale#Escape('clang-tidy')
  \   . ' -checks=' . ale#Escape('*') . ' %s'
  \   . ' -p ' . ale#Escape('/foo/bar')

  call ale#test#SetFilename('test.hpp')

  AssertLinter 'clang-tidy',
  \ ale#Escape('clang-tidy')
  \   . ' -checks=' . ale#Escape('*') . ' %s'
  \   . ' -p ' . ale#Escape('/foo/bar')

Execute(The executable should be configurable):
  let b:ale_cpp_clangtidy_checks = ['*']
  let b:ale_cpp_clangtidy_executable = 'foobar'

  AssertLinter 'foobar',
  \ ale#Escape('foobar') . ' -checks=' . ale#Escape('*') . ' %s'
