Testing Editorial Review

Overall, customers seem to find this book on unit testing to be a valuable resource. One user describes it as a "bible" that they keep coming back to for references and examples. However, there are mixed feelings about the repetition found throughout the book, with one reviewer mentioning that it can be excessive even within the same chapter. Despite this, the inclusion of online materials is appreciated by some readers. The real value of the book seems to lie in its practical examples, especially in JavaScript, making it useful for those learning the language. For many customers, this is their first book solely dedicated to unit testing, making it a valuable addition to their library. **
