My daily work at Fuery Solutions involves finding ways to "break" MerusCase. Sounds crazy, I know. But, let me elaborate. In a nutshell, I write code that tests the application piece by piece. This, in very general terms, is what is known as unit testing. I help test the code that runs in the server as well as test the code that runs for the client that is responsible for the graphical user interface. Some testing and troubleshooting has to be done manually, as well. After verifying that all the parts of the application work as they are expected on their own, we also need to test how well they interact with one another; this is what is known as integration testing.
