I want to know what Mockito is. Is it supporting JUnit or is it an environment for writing JUnit test cases? Can someone please explain to me the differences between JUnit and Mockito?
The short answer is, behind the scenes, Mockito uses some kind of global variables/storage to save information of method stub building steps (invocation of method (), when (), thenReturn () in your example), so that eventually it can build up a map on what should be returned when what is called on what param.

I get this warning while testing in Spring Boot: Mockito is currently self-attaching to enable the inline-mock-maker. This will no longer work in future releases of the JDK. Please add Mockito as an
If the verified method called 2+ times, mockito passes all the called combinations to each verifier. So mockito expects your verifier silently returns true for one of the argument set, and false (no assert exceptions) for other valid calls. That expectation is not a problem for 1 method call - it should just return true 1 time.
The following are examples about how to set up mockito-core as a Java agent, and it may be more appropriate to choose a different approach depending on your project constraints. To explicitly attach Mockito during test execution, the library's jar file needs to be specified as -javaagent as an argument to the executing JVM.
There are many ways to initialize a mock object using MockIto. What is best way among these ? 1. public class SampleBaseTestCase { @Before public void initMocks() { MockitoAnnotations.
Mockito is unfortunately making the distinction weird. A mock in mockito is a normal mock in other mocking frameworks (allows you to stub invocations; that is, return specific values out of method calls). A spy in mockito is a partial mock in other mocking frameworks (part of the object will be mocked and part will use real method invocations).
The Mockito documentation states that this pattern should not be abused -- "A word of warning: Some users who did a lot of classic, expect-run-verify mocking tend to use verifyNoMoreInteractions () very often, even in every test method. verifyNoMoreInteractions () is not recommended to use in every test method. verifyNoMoreInteractions () is a ...
Is there any way, using Mockito, to mock some methods in a class, but not others? For example, in this (admittedly contrived) Stock class I want to mock the getPrice() and getQuantity() return val...
How to mock void methods with mockito - there are two options: doAnswer - If we want our mocked void method to do something (mock the behavior despite being void). doThrow - Then there is Mockito.doThrow() if you want to throw an exception from the mocked void method. Following is an example of how to use it (not an ideal usecase but just wanted to illustrate the basic usage).
