One of the quickest ways to assert that you indeed have a memory leak is to enable verbose garbage collection. Memory constraint problems can usually be identified by examining patterns in theverbosegcoutput. Specifically, the-verbosegcargument allows you to generates a trace each time the garbage...
Consider a test that is written by using the Arrange, Act, Assert pattern: Arrange: Allocate resources (a queue to receive messages, and the function under test). Act: Call the function under test. Assert: Retrieve the message sent by the function, and validate the output. A mock testing...
