How do you do unit testing and integration testing?
Unit Testing is typically performed by the developer. It is a testing method using which every independent modules are tested to determine if there are any issue by the developer himself. Integration Testing: Integration testing is the process of testing the interface between two software units or modules.
What is a program that invokes the unit under test?
A unit test is an automated piece of code that invokes the unit of work being tested, and then checks some assumptions about a single end result of that unit. A unit test is almost always written using a unit testing framework. It can be written easily and runs quickly.
How is dependency injection used in unit testing?
Dependency Injection (DI): This gives you control of the testing environment. Instead of creating forreign objects inside your code, you inject it through the class constructor or the method call. When unittesting, you simply replace real classes by stubs or mocks, that you control entirely.
How to unit test methods that call other methods inside same?
Also allows for testing if a static Func was called from another method since static methods can not be mocked. Easy to refactor existing methods to Funcs/Actions since the syntax for calling a method on the call site remains the same. (For times when you can’t refactor a method into a Func/Action see cons)
How to start unit testing in Visual Studio?
To follow these steps, Visual Studio Enterprise is required. Turn live unit testing from the Test menu by choosing Test > Live Unit Testing > Start. View the results of the tests within the code editor window as you write and edit code. Click a test result indicator to see more information, such as the names of the tests that cover that method.
What are the pros and cons of unit test methods?
The biggest Con is that you don’t have access to the ‘this’ reference in Funcs and Actions, and so any dependencies on the class must be explicitly passed in as parameters. Its good as you know all dependencies but bad if you have many properties that your Func will depend on. Your mileage will vary based on your use case.
