+Basic tests for AudioNode API.
+
+On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
+
+PASS Source AudioNode has no inputs.
+PASS Source AudioNode has one output.
+PASS connect() exception thrown for illegal destination AudioNode.
+PASS connect() exception thrown for illegal output index.
+PASS connect() exception thrown for illegal input index.
+PASS audioNode.connect(context.destination) succeeded.
+PASS successfullyParsed is true
