Introduction
Mock object
In object-oriented programming, mock objects are simulated objects that mimic the behavior of real objects in controlled ways. In a unit test, mock objects can simulate the behavior of complex, real objects and are therefore useful when a real object is impractical or impossible to incorporate into a unit test. Mock objects have the same interface as the real objects they mimic, allowing a client object to remain unaware of whether it is using a real object or a mock object. Many available mock object frameworks allow the programmer to specify which, and in what order, methods will be invoked on a mock object and what parameters will be passed to them, as well as what values will be returned. Thus, the behavior of a complex object such as a network socket can be mimicked by a mock object, allowing the programmer to discover whether the object being tested responds appropriately to the wide variety of states such mock objects may be in.
EntitymockDSL
In our implementation, we use a complex database, which would have to be initialized. If you do hand-entering data one by one, you will waste so much time to build up the volume and variety of data that we need. So we design to generate all mock objects for our database by initialization using entitymockDSL.
The main semantic elements of the EntitymockDSL are:
- “mock entitymodel” - the root element that contains all the other elements. A model can contain multiple mock entitymodels.
- “import” declarations - used to import external models or even Java classes.
- “datainterchanges” - define the imported datainterchange model to fill the mock data.
- “resources” - define all availabilities of a resource definition. Resources will be used as enum in objects or directly in the definition of mock entities.
- “objects” - contains consistent information for some kind of object definition. Objects are used as template for mock entities.
- “mock entities” - define the mocking rules of entities.
