JUnit, Mockito

Are written for single software parts. Typically one unit test in Java verifies one class method.

• Mockito
• JMockit
• EasyMock

Is a good practice annotate for any attribute if it is a @InjectMocks, @Mock, @Spy or @Captor

@Autowired provides control over where and how binding between beans should be performed. Can be used to in setter methods, in the constructor, in a property or methods with arbitrary names and/or multiple arguments.

@MockBean to replace beans with mocked beans.

@Test to determine that the next method is a test

@SpringBootTest to determine that this class is a Class test of SpringBoot, the test with this annotation will take much longer to execute then a simple unit test. Is used to integration tests.

@SpyBean to create a spy bean instante
