Can ws be declared here? (Or, it isn't needed, maybe?)

I did like this because I wanted to capture exceptions only from the
constructor. But now we have nothing other than the construction to do in this
test.

Done

+    } catch (e) {
+        reportResult("DONE");
+        return;
+    }
+    reportResult("FAIL: No exception was thrown")
+})();
