What you're doing here is probably
echo $y | grep errors
which write ' full of errors' to stdout and then insert stdout into the string
[ full of errors]
which becomes a call to 'test' with arguments 'full' 'of' 'errors]'
which is not any expression the test command recognizes.

You need to give arguments the test command will recognises,
such -n string, properly quote the arguments, and you should space
the brackets. In bourne shell it would look like
if [ -n "`echo $y | grep errors`" ]
then
echo "errors found"
