JMOCK TUTORIAL PDF

Today I held a mock dojo (one and a half hour) in order to introduce mocking and JMock to my audience. This post is intended to be the first. Too hard to test things that involve external components? • Too slow, even if you could? • Unit Tests as much fun as smacking yourself in the head with a. Here is a tutorial about using JUnit and EasyMock (a mocking library I personally find far easier to use than JMock).

We then register the Subscriber with the Publisher.

To test interactions between the Publisher and the Subscriber we will use a mock Subscriber object. For example, you may want to test a business operation which happens to, at some point, send an e-mail.

Getting Started

Sign up using Email and Password. OK, now we are really ready to mock classes.

In order to verify the e-mail was correctly sent, the test could mock the e-mail sending API, while exercising the real code in every other component an alternative would be to set up some kind of fake e-mail server which could be consulted in an assertion at the end of the test.

We will test that a Publisher sends a message to a single registered Subscriber.

Understand better trough examples, what else could I test here or any other exercises would help me a lot. Keep in mind that this object doesn’t implement the behavior of the object it’s mocking.

All the other referenced classes are empty.

jMock – Getting Started

Is it a class in Java or user defined if so then whats its content. People usually read these too Even though integration tests include the interaction between multiple units, particular tests jmoc, not be interested in exercising all components, layers, or sub-systems involved. It takes care of the assertion housekeeping at the right time. Does anybody have better way to learn this. We create a Publisher to test.
