PASS Can get the ReadableStreamDefaultReader constructor indirectly 
PASS ReadableStreamDefaultReader constructor should get a ReadableStream object as argument 
PASS ReadableStreamDefaultReader instances should have the correct list of properties 
PASS ReadableStreamDefaultReader closed should always return the same promise object 
PASS Constructing a ReadableStreamDefaultReader directly should fail if the stream is already locked (via direct construction)
