How do you mock a container in unity?

Just in case someone needs to mock this out and can’t remove the dependency on the container. Remove the dependency on IUnityContainer and things become a lot easier and cleaner. Instead let unity inject your dependencies which are abstracted into interfaces. These are easily mocked.

What is unity container?

The Unity Container (Unity) is a lightweight, extensible dependency injection container. It facilitates building loosely coupled applications and provides developers with the following advantages: Simplified object creation, especially for hierarchical object structures and dependencies.

Can you mock HttpClient?

Yes, we already have few ways to mock httpclient by writing a wrapper for HttpClient. But there is a problem for not covering test cases for HttpClient class, since we know there isn’t an interface inherited with HttpClient. To handle this case, we introduced HttpClient property in the interface.

How does mock work in unit testing?

Mocking is a process used in unit testing when the unit being tested has external dependencies. The purpose of mocking is to isolate and focus on the code being tested and not on the behavior or state of external dependencies. To test for different use cases, a lot of Fakes must be introduced.

What means dependency injection?

Dependency Injection (DI) is a programming technique that makes a class independent of its dependencies. “In software engineering, dependency injection is a technique whereby one object supplies the dependencies of another object. A ‘dependency’ is an object that can be used, for example as a service.

What is Unity dependency injection?

Dependency Injection (DI) Dependency Injection is defined as a design pattern that allows removing hard-coded dependencies from an application. “Inversion of control is principal and Dependency Injection is implementation”. Now let’s start with implementing Dependency Injection using the Microsoft Unity Framework.

How do you mock an Okhttp response?

  1. You can mock (with mockito, jmockit, etc) the client.newCall(request).execute() calls to return an expected response and check for the number of invocations, or maybe the simpler way, use the okhttp-client-mock (MIT), setup your rule for 3 times, and check that it was consumed.
  2. Or potentially use a mock-server.

How do you mock a protected method?

How do I use Mockito to mock a protected method?

  1. declare your test in the same package as the mocked class.
  2. change the visibilty of the method if you can.
  3. create a local (inner) class that extends the mocked class, then mock this local class. Since the class would be local, you would have visibility to the method.

How do you mock data?

The following two options for providing mock data exist:

  1. Provide your own mock data. You can provide JSON files as test data for the mock server to produce the output.
  2. Mock server generates the mock data. The mock server can produce random mock data based on the service metadata it simulates.

What is the purpose of dependency injection?

Dependency injection is a programming technique that makes a class independent of its dependencies. It achieves that by decoupling the usage of an object from its creation. This helps you to follow SOLID’s dependency inversion and single responsibility principles.

What are the types of dependency injection?

There are basically three types of dependency injection:

  • constructor injection: the dependencies are provided through a class constructor.
  • setter injection: the client exposes a setter method that the injector uses to inject the dependency.
