+
+    \relates QTest
+
+    This macro is used to measure the performance of code within a test.
+    The code to be benchmarked is contained within a code block following
+    this macro.
+
+    Unlike QBENCHMARK, the contents of the contained code block is only run
+    once. The elapsed time will be reported as "0" if it's to short to 
+    be measured by the selected backend. (Use)
