What You Need to Check In Your Model Program

Overview of QA Methods for Web Apps
Overview of QA Methods for Web Apps
  1. Check the input encoding. Make sure that in your model the input encoding corresponds to its implementation. If these processes are different, find out where in the model or in the program the error is. The way you can verify this depends on what you are encoding. If the inputs are numbers, then to test the encoding, you may be able to use the domain testing method. If inputs are character strings you may use syntactic testing or another state-based testing. Either way, you must confirm that your model and program process input events in the same way and explain all the discrepancies, if any.

 

  1. Check the output encoding. You should have relatively few output events or sequences of actions. Name each of them. If the encoded output “A” means “open the file, update the file, close the file, report the execution”, then you should make sure that all these actions have taken place, and in this sequence.

 

You can examine the intermediate computational steps, the file activity protocol, use the symbolic debugger … However, whatever path you choose, you must make sure that your output codes correspond to the sequence of actions in the real program and explain all the discrepancies if there is no such correspondence.

  1. Are you in the initial state? There are methods assuming the existence of at least one initial state, as well as the possibility to reach it. Several initial states can be present in complex systems. For example, the initial state for an operation performed by an individual user is likely to differ from the initial state for a network operation. You cannot start the test until you have discovered and investigated the initial state. The program messages informing that you are in the initial state are not enough. In the end, it can be just the error you are looking for. The initial state has certain properties, such as a list of open files, resources used, active programs, and so on. Check this all. If your initial state is something like a bootstrapping or loading into memory, you should check each state and every transition in this set of states. This can be quite difficult if you do not use the appropriate tools for development of your tests, because such sequences are often performed automatically. The process involving a series of steps to follow in tracking transitions is extraordinarily useful during the test.
