Test fn-put-011 claims to be testing that put() isn't effective until after the end of the query. It does this by reading the document at the relevant URI and hoping for a failure. But it's likely that there will be a document at that location left over from previous runs, and reading it will succeed.

I would suggest rewriting this test as:

let $var := $input-context/works[1]/employee[1]
let $file := concat("temp/", current-dateTime())
return
   (
   fn:put(document { <test/> }, $file),
   insert node fn:doc($file)/* as last into $var
   )

(It's not nice to write to random file locations; but if the system under test is working to spec, the file should never get written, because the error in fn:doc() will prevent the PUL being actioned.)
