Build Your Own Test Framework - Daniel Irvine - Bog - APress - Plusbog.dk

Build Your Own Test Framework - Daniel Irvine - Bog - APress - Plusbog.dk

Learn to write better automated tests that will dramatically increase your productivity and have fun while doing so. This book is a build-your-own adventure designed for individual reading and for collaborative workshops. You will build an xUnit automated test framework using JavaScript: initially a clone of Jest, but adding a couple of neat features borrowed from RSpec, the genre-defining tool for behavior-driven development (BDD). Along the way, you will explore the philosophy behind automated testing best practices. The automated test runner is one of the most important innovations within software engineering. But for many programmers, automated testing remains a mystery, and knowing how to write good tests is akin to sorcery. As the chapters of this book unfold, you will see how the humble test runner is an elegant and simple piece of software. Each chapter picks a single feature to build, like the "it" function or the "beforeEach" block. It picks apart the theory of why the feature needs to exist, and how to use it effectively in your own test suites. Every chapter ends with a set of ideas for extension points should you wish to explore further, alone or in groups. The book culminates in an implementation of test doubles and mocks-one of the most difficult and misunderstood concepts within automated testing. By the end of the book, you will have gained a solid understanding of automated testing principles that you can immediately apply to your work projects. What You''ll Learn - Build an xUnit automated test framework - See how an automated test runner works - Understand the best practices for automated unit testing - Effectively use test doubles and mocks Who This Book Is For Software developers with JavaScript experience who are seeking to master the art of automated testing.

Modern Software Testing Techniques - Attila Kovacs - Bog - APress - Plusbog.dk

Modern Software Testing Techniques - Attila Kovacs - Bog - APress - Plusbog.dk

Many books have been written about software testing, but most of them discuss the general framework of testing from a traditional perspective. Unfortunately, traditional test design techniques are often ineffective and unreliable for revealing the various kinds of faults that may occur. This book introduces three new software testing techniques: Two-Phase Model-Based Testing, the Action-State Testing, and the General Predicate Testing, all of which work best when applied with efficient fault revealing capabilities. You’ll start with a short recap of software testing, focusing on why risk analysis is obligatory, how to classify bugs practically, and how fault-based testing can be used for improving test design. You’ll then see how action-state testing merges the benefits of state transition testing and use case testing into a unified approach. Moving on you’ll look at general predicate testing and how it serves as an extension of boundary value analysis, encompassing morecomplex predicates. Two-phase model-based testing represents an advanced approach where the model does not necessarily need to be machine-readable; human readability suffices. The first phase involves a high-level model from which abstract tests are generated. Upon manual execution of these tests, the test code is generated. Rather than calculating output values, they are merely checked for conformity. The last part of this book contains a chapter on how developers and testers can help each other and work as a collaborative team. What You'll LearnApply efficient test design techniques for detecting domain faultsWork with modeling techniques that combine all the advantages of state transition testing and uses case testingGrasp the two-phase model-based testing technique Use test design efficiently to find almost all the bugs in an applicationWho This Book Is ForSoftware developers, QA engineers, and, business analysts
