The first part sets the arena for the rest of the book by providing concise definitions of what Unit and Integration tests are, as well as introducing the reader to the concept of Test Driven Development (TDD). Part 1 ends with chapter 2 that walks the reader through an example of putting together their first unit test.
The second part then starts looking at ways of making your code loosely coupled so that you can test more effectively and start using Fake objects. Roy does this by introducing the concept of Dependency Injection (DI), otherwise known as Inversion of Control (IoC), and then how you can utilise DI to make use of Stub and Mock objects in your tests. The second part ends with the introduction of Isolation Frameworks and looks at how they can ease the complexity of using Stubs and Mocks in your Unit Tests.
The third part then starts moving in to the more practical side of Unit testing now that the groundwork has been established in the first 2 parts. Roy takes the reader through the various patterns that can be used for test classes and how you can utilise them in a Test Hierarchy. Roy highlights that a Automated Build process is essential for running your test regularly to pick up any breaking changes that may have occurred in your application. Chapter 7 then moves onto the critical area of how to write tests that are maintainable, trustworthy and readable.Read more ›
An excellent book, I would recommend it if:
* You are completely new to Unit Testing.
* You have been Unit Testing for a short while and looking to see what the next step for you is.
If you have been a hardcore TDD practitioner for years, then I would expect that this book is not for you since you would have likely hashed all the issues covered in the book.
There are a lot of great anecdotes in the book, many of which rang home with me and personal experience. Which (for me) just affirms that the content is good.
A real nice, relatively short read. Great job Roy!
After reading this book I have a very clear vision of what's right and what's not. I is written in a very easy-to-understand way with clear examples and well reasoned explanations. It shows the novice (and not so novice) test writer how they should go about writing clear, reliable and maintainable tests. There is some really great advice to get the reader up and running in no time at all, and best of all, with the confidence that what they are writing will stand the test of time in any development environment.
It also make very clear how to implement stubs and mocks and what rôle they play in the testing environment.
A truly great read and very highly recomended.
It's an easy read, that goes through what makes a good unit test, how to write a simple unit test using NUnit, how to replace dependencies with manually created stubs, how to manually create mocks, then how to use a mocking framework (e.g. RhinoMocks) to dynamically creates stubs and mocks. There's useful advice on things like naming conventions, how to organise projects and folders, integrating into the build system, how to introduce unit testing into an organisation, and how to work with legacy code. There's also advice on OOD for testability, including interface driven development and use of inheritance in order to break dependencies or allow insertion of objects to allow unit testing to take place (this has been a serious mental block for some developers I have worked with in the past - not being able to recognise that, with a little re-factoring, code that they thought could only be tested using integration/system testing can have dependencies broken to allow unit testing to take place). Together with numerous links/references to other tools and materials, this is a great, easy to read, and fairly short, introduction. It's one of a short list of books that I think all .Net developers should read.
This is not, however, the complete guide to unit testing in the .Net world. For example, it touches on Inversion of Control containers (e.g. Castle Windsor) but doesn't go into any detail. It mentions patterns for unit testing, but directs the reader elsewhere for more information. It touches on Test Driven Development, but doesn't really follow it through.Read more ›
