EasyMock supports creating partial mock, where we can specify the methods that will be mocked. If any other method is called, object real method will get invoked. EasyMock Partial Mock Example Let’s say we have a utility class defined as: package com.journaldev.utils; public class StringUtils { public void print(String s) { System.out.println(s); } public String […]
EasyMock Nice and Strict Mock
EasyMock mock objects can have three types – default, strict and nice. We can specify mock object type using MockType enum while creating the mock object. EasyMock Mock Types Default: Expects only recorded calls but in any order. Test won’t fail if any recorded calls are skipped. Strict: Expects only recorded calls and in the […]
EasyMock Verify
EasyMock Verify method is used to verify that all the stubbed methods are called and there are no unexpected calls on the mocked object. EasyMock Verify EasyMock verify() method has the same effect as calling verifyRecording(Object) and verifyUnexpectedCalls(Object) methods. Let’s look at a simple example of EasyMock verify() method. package com.journaldev.easymock; import static org.easymock.EasyMock.expect; import […]
EasyMock Mock Exceptions
EasyMock allows us to mock exceptions when a specific method is called. We can do this using andThrow() method along with expect(). EasyMock Mock Exception Example Let’s say we have a following class. package com.journaldev.utils; public class StringUtils { public String toUpperCase(String s) { return s.toUpperCase(); } } Here is the example of mocking StringUtils […]
EasyMock Annotations – JUnit 4
EasyMock annotations can be used to create Mock objects. We can also tell the EasyMock framework to inject these mock objects into another concrete class. EasyMock Annotations There are two important EasyMock annotations that we should be aware of: @Mock: Used to specify a field to be mocked by EasyMock. @TestSubject: Used to specify an […]
EasyMock TestNG Example
In the EasyMock Tutorial, we used it with JUnit 5. In this tutorial, we will learn how to integrate EasyMock with TestNG testing framework. EasyMock TestNG Example We will build up our EasyMock TestNG example from the earlier tutorial. First of all, we will have to add the TestNG dependency to the already existing EasyMock […]
EasyMock Tutorial
EasyMock is a java based mocking framework, which is used in conjunction with other unit testing frameworks such as JUnit and TestNG. EasyMock is very similar to Mockito mocking framework. EasyMock allows us to create mock objects of interfaces and concrete classes and specify their behaviors. Then we can use these mocks to write code […]
Mockito Iterator Style Stubbing of Consecutive Calls
Sometimes we want to mock different responses for the consecutive calls on the same method. We can create then* methods chain with when() to specify iterator style stubbing in Mockito. Mockito Stubbing Consecutive Calls Let’s look at a simple example of mocking exception and return a response when a method is called with same parameters. […]
Mockito Mock Static Method – PowerMock
Mockito allows us to create mock objects. Since static method belongs to the class, there is no way in Mockito to mock static methods. However, we can use PowerMock along with Mockito framework to mock static methods. Mockito Mock Static Method using PowerMock PowerMock provides different modules to extend Mockito framework and run JUnit and […]
Mockito ArgumentCaptor, @Captor Annotation
Mockito ArgumentCaptor is used to capture arguments for mocked methods. ArgumentCaptor is used with Mockito verify() methods to get the arguments passed when any method is called. This way, we can provide additional JUnit assertions for our tests. Mockito ArgumentCaptor We can create ArgumentCaptor instance for any class, then its capture() method is used with […]
