A Test Double is a generic term used for these objects. We are replacing real functionality to provide values needed for method to perform its job. An example of this shortcut, can be an in-memory implementation of Data Access Object or Repository. This is not responsibility of SecurityCentral. the various Xunit frameworks. Benchmarking pro. Attention: double tâche! In simple terms, test cases for each functionality are created and tested first and if the test fails then the new code is written in order to pass the test and making code simple and bug-free. You may ask how can we tell if door and window will be closed for real if we use mock? Usually they take some shortcut and have simplified version of production code. The very first example you give for the application of a Two-Sample T-test is to compare “the average success rates before and after a new sales tool is implemented”. Method averageGrades, that returns average of student grades is a good example. This is when a method performs some actions, that changes the system state, but we don’t expect any return value from it.void sendReminderEmail(Student student); A good practice is to divide an object's methods into those two separated categories.This practice was named: Command Query separation by Bertrand Meyer in his book "Object Oriented Software Construction".

We define just enough data to test average calculation algorithm. My understanding was that this would be an example of a Paired T-test, which would determine if a significant difference existed between the SAME sample at two different points in time (i.e. Only thing we can do is to verify the outputs of the functionality that is exercised in our test. after the training event).

For testing Query type methods we should prefer use of Stubs as we can verify method’s return value. Instead of the real object, we introduced a stub and defined what data should be returned. There are two different approaches that can be used to create an in-memory version of your context. This gives you a lot of control over how the classes behave but can involve writing and owning a reasonable amount of code.
