@test logical.vm

This template is used for Velocity regression testing.
If you alter this template make sure you change the
corresponding comparison file so that the regression
test doesn't fail incorrectly.

#set($foo = 5)

#if ($foo > 1)
    \$foo is greater then 1

goofy but legal stuff

#set($lala = ( false || true ) )
Should equal true : $lala

#set($fofo = ( true && true ) )
Should equal true : $fofo

#set($fofo = ( true && ( false || true ) ) )
Should equal true : $fofo

#set($fofo = ( ($t || $f) && $t))
Should equal true : $fofo

#if($x == false)
right

wrong

Test to see if we can do logical assignment from any expression

#set($val = (3 == 3))
#if($val == true)
right
#else
wrong
#end

#set($val = (1 < 2))
#if( $val == true)
right
#else
wrong
#end


#set($val = (1 <= 2))
#if( $val == true)
right
#else
wrong
#end


#set($val = (7 > 2))
#if( $val == true)
right
#else
wrong
#end

#set($val = (7 >= 2))
#if( $val == true)
right
#else
wrong
#end

#set($val = ( 1 != 2))
#if( $val == true)
right
