How to use mockConstruction method of org.mockito.Mockito class

Best Mockito code snippet using org.mockito.Mockito.mockConstruction

What is mockconstruction in Mockito?

With the mockConstruction you can mock calls made to the constructor. Let us illustrate this with an example:

copy
1class Car { 2 public Car() {} 3 public String makeSound() {return "Vroom";} 4} 5 6@Test 7void mockingConstructor() { 8 9 // Scope of constructor mocking 10 try (MockedConstruction<Car> mock = mockConstruction(Car.class)) { 11 // creating a mock instance 12 Car car = new Car(); 13 when(car.makeSound()).thenReturn("Weee"); 14 15 assertThat(car.makeSound()).isEqualTo("Weee"); 16 17 // Get a list of all created mocks 18 List<Car> constructed = mock.constructed(); 19 assertThat(constructed).hasSize(1); 20 } 21 22 // Normal Car instance that is not mocked 23 assertThat(new Car().makeSound()).isEqualTo("Vroom"); 24 25}

We mock the Car class's constructor, which is called from the test code. Within a try statement, we limit the scope to prevent any further calls to the constructor. When your code calls the constructor inside this try statement, it returns a mock object. Outside that try statement, calls to the class's constructor will not be mocked by Mockito. This example also works when you mock a private constructor. If the Car class had a private constructor, calls to it would still succeed outside of our try-with-resources statement.
