Execute(The clangtidy command default should be correct):
  AssertEqual
  \ ale#Escape('clang-tidy')
  \   . ' -checks=' . ale#Escape('*') . ' %s',
  \ ale_linters#c#clangtidy#GetCommand(bufnr(''))

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

  AssertEqual
  \ ale#Escape('clang-tidy')
  \   . ' %s',
  \ ale_linters#c#clangtidy#GetCommand(bufnr(''))

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

  AssertEqual
  \ ale#Escape('clang-tidy')
  \   . ' -checks=' . ale#Escape('-*,clang-analyzer-*') . ' %s',
  \ ale_linters#c#clangtidy#GetCommand(bufnr(''))

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

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

Execute(The build directory should be configurable):

  AssertEqual

  \   . ' -checks=' . ale#Escape('*') . ' %s'
  \   . ' -p ' . ale#Escape('/foo/bar'),
  \ ale_linters#c#clangtidy#GetCommand(bufnr(''))

Execute(The build directory setting should override the options):
  let b:ale_c_build_dir = '/foo/bar'
  let b:ale_c_clangtidy_options = '-Wall'

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

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

  let b:ale_c_build_dir = '/foo/bar'
  let b:ale_c_clangtidy_options = '-Wall'

  AssertEqual
