It's hard to tell what is going on without an actual testcase.
If you can come up with a simple self-contains example including
test files that would help.  I realize that may be awkward as
the point of your code it to iterate over a bunch of files.

One suggestion:  Try replacing:

    for $x in get-test-description()/test,
        $y in get-test-results()/testsuite
       where $y/properties/property/@value = $x/@id
       return <testreport>{$x} {$y}</testreport>

by something like:

    let $xs in get-test-description()/test,
        $ys in get-test-results()/testsuite,
    for $x in $xs
    return <current-x>{$x}{
    for $y in $ys
    let $xid=$x/@id, $yval=$y/properties/property/@value
return
    <current-y y-value="{$yval}" x-id="{$xid}"
matches="{$yval=$xid}">{$y}</current-y>}
     </current-x>


Or something like it, to print out more useful debugging data.

Note in your original code get-test-results()/testsuite
get re-evaluated for each $x, which is inefficient.
