EASYMOCK TUTORIALS PDF

However, EasyMock has certain limitations too. If these methods are called on mock object, then normal methods will get called. EasyMock provides built-in behavior for equals , toString , hashCode and finalize methods. EasyMock Maven Dependencies We can add the following dependencies to our maven project to use the EasyMock mocking framework. We will use JUnit 5 for writing test cases along with EasyMock for creating mock objects.

Next Page What is Mocking? Mocking is a way to test the functionality of a class in isolation. Mocking does not require a database connection or properties file read or file server read to test a functionality. Mock objects do the mocking of the real service. A mock object returns a dummy data corresponding to some dummy input passed to it. EasyMock EasyMock facilitates creating mock objects seamlessly.

It uses Java Reflection in order to create mock objects for a given interface. Mock objects are nothing but proxy for actual implementations. Consider a case of Stock Service which returns the price details of a stock. During development, the actual stock service cannot be used to get real-time data. So we need a dummy implementation of the stock service.

EasyMock can do the same very easily as its name suggests. Refactoring Safe — Renaming interface method names or reordering parameters will not break the test code as Mocks are created at runtime. Return value support — Supports return values. Exception support — Supports exceptions. Order check support — Supports check on order of method calls. Annotation support — Supports creating mocks using annotation. Consider the following code snippet.

ArrayList; import java. List; import org. The complete code is available in the chapter First Application. Portfolio — An object to carry a list of stocks and to get the market value computed using stock prices and stock quantity. Stock — An object to carry the details of a stock such as its id, name, quantity, etc. StockService — A stock service returns the current price of a stock.

They should be ensured that the code works properly after a new feature was implemented or some bug was fixed. That can be achieved with the help of unit tests. Since this blog is dedicated to the Java programming language, today I will write an article about the JUnit 4. The main purpose of these frameworks is to make writing of unit tests easier.
