set "FOO=bar"
echo %FOO%

echo ------------ Testing if/else --------------
echo if/else should work with blocks

  echo if seems to work
) else (
  echo if seems to be broken
)
if 1 == 0 (
  echo else seems to be broken
) else (
  echo else seems to work
)
echo Testing case sensitivity with and without /i option
if bar==BAR echo if does not default to case sensitivity
if not bar==BAR echo if seems to default to case sensitivity
if /i foo==FOO echo if /i seems to work
if /i not foo==FOO echo if /i seems to be broken
if /I foo==FOO echo if /I seems to work
if /I not foo==FOO echo if /I seems to be broken

echo -----------Testing del /a-----------
del /f/q *.test > nul
echo r > r.test
attrib +r r.test
echo not-r > not-r.test

if not exist not-r.test echo not-r.test not found before delete, bad
del /a:-r *.test
if not exist not-r.test echo not-r.test not found after delete, good

if not exist r.test echo r.test not found before delete, bad
if exist r.test echo r.test found before delete, good
del /a:r *.test
if not exist r.test echo r.test not found after delete, good
if exist r.test echo r.test found after delete, bad

echo ------------ Testing del /q --------------
mkdir del_q_dir
cd del_q_dir
echo abc > file1
echo abc > file2.dat
rem If /q doesn't work, cmd will prompt and the test case should hang
del /q * > nul
for %%a in (1 2.dat) do if exist file%%a echo del /q * failed on file%%a
for %%a in (1 2.dat) do if not exist file%%a echo del /q * succeeded on file%%a
cd ..
rmdir del_q_dir

echo ------------ Testing del /s --------------
mkdir "foo bar"
cd "foo bar"
echo hi > file1.dat
echo there > file2.dat
echo bub > file3.dat
echo bye > "file with spaces.dat"
cd ..
del /s file1.dat > nul
del file2.dat /s > nul
del "file3.dat" /s > nul
del "file with spaces.dat" /s > nul
cd "foo bar"
for %%f in (1 2 3) do if exist file%%f.dat echo Del /s failed on file%%f
for %%f in (1 2 3) do if exist file%%f.dat del file%%f.dat
if exist "file with spaces.dat" echo Del /s failed on "file with spaces.dat"
if exist "file with spaces.dat" del "file with spaces.dat"
cd ..
rmdir "foo bar"

echo -----------Testing Errorlevel-----------
rem nt 4.0 doesn't really support a way of setting errorlevel, so this is weak
rem See http://www.robvanderwoude.com/exit.php
call :setError 1
echo %ErrorLevel%
if errorlevel 2 echo errorlevel too high, bad
if errorlevel 1 echo errorlevel just right, good
call :setError 0
echo abc%ErrorLevel%def
if errorlevel 1 echo errorlevel nonzero, bad
if not errorlevel 1 echo errorlevel zero, good
rem Now verify that setting a real variable hides its magic variable
set errorlevel=7
echo %ErrorLevel% should be 7
if errorlevel 7 echo setting var worked too well, bad
call :setError 3
echo %ErrorLevel% should still be 7

echo -----------Testing GOTO-----------
if a==a goto dest1
:dest1
echo goto with no leading space worked
if b==b goto dest2
 :dest2
echo goto with a leading space worked
if c==c goto dest3
	:dest3
echo goto with a leading tab worked
if d==d goto dest4
:dest4@space@
echo goto with a following space worked

echo -----------Done, jumping to EOF-----------
goto :eof
rem Subroutine to set errorlevel and return
rem in windows nt 4.0, this always sets errorlevel 1, since /b isn't supported
:setError
exit /B %1
rem This line runs under cmd in windows NT 4, but not in more modern versions.
