商品描述

Learn how to create stubs, mocks, and spies and verify their behavior using Mockito

Overview

  • Learn something new in an Instant! A short, fast, focused guide delivering immediate results
  • Stub methods with callbacks
  • Verify the behavior of test mocks
  • Assert the arguments passed to functions of mocks
  • Create custom argument matchers

In Detail

Mockito is an open source testing framework for Java that automates unit tests for use in test-driven development (TDD) or behavior-driven development (BDD), decoupling test code from the system under test by eliminating the expect-run-verify pattern. It lets you write beautiful tests with a clean and simple API.

Instant Mockito contains plenty of real-life examples on how to unit test your code. It shows you how to use this testing framework and explains best practices on how to use it effectively.

Instant Mockito helps you break each significant method into a set of practical examples. It will clarify all the concepts of unit testing and Mockito.

You will learn how to properly capture and verify arguments passed into your stubbed methods. We will also take a look at verifying an order and returning custom answers on the stubs. If you want to take advantage of using the Mockito framework’s API to tame your code base, then this is the book for you.

You will learn everything you need to know to unit test your code in a clear, readable, and high quality manner.
