A use case? I think the three laws need to be a little clearer.
In my experience, unit tests are centered around a test instance of a class. Unit tests are written around different functions inside the class and test different constraints of the function or the results of the function.
So perhaps this is what Martin is getting at with the three laws. Also tests can either test the state of the object or it can test the ability to interact as expected with mock objects. Martin, however, does stress the importance of TDD, and gives examples through JUnit of how to write good unit tests against your code.
Dependency Injection Martin describes the importance of dependency injection and using an IoC Container Inversion of control container. An IoC container allows you to utilize a framework, such as Spring Unity in the.
NET world , to hook up the dependencies of your objects upon construction. He tells how IoC moves the responsibility of constructing objects away from the objects themselves, therefore adhering well to SRP. The nice thing about frameworks like Spring is you can describe all your dependencies in an XML file and easily manipulate the type of construction and dependencies of construction of different classes.
Inside this file you can also swap in and out different concrete types. This is a powerful feature, because inside your code, you may just be passing in an interface into a constructor, but the IoC container describes which of the concrete classes is in the underlying object.
An example of the power of dependency injection is say you wanted to provide data to a particular class through a data provider.
You could create a constructor in your class that took an interface for all data providers. You could then, for example, change to a different data provider in your IoC container. The code for the classes receiving the data provider in their constructor as an interface , would not have to change as long as the data provider you swapped out had the same interface.
In any case, the code smells, as they are called, are gems because we all have come across them, and many of have certainly coded them.The result is a knowledge base that describes the way we think when we write, read, and clean code. What kind of work will you be doing?
Test Boundary Conditions T6: Each case study is an exercise in cleaning up code—of transforming a code base that has some problems into one that is sound and efficient. The code for the classes receiving the data provider in their constructor as an interface , would not have to change as long as the data provider you swapped out had the same interface.
Use Explanatory Variables G Martin, however, does stress the importance of TDD, and gives examples through JUnit of how to write good unit tests against your code.
