Software Test Design

By: Simon Amey

Overview of this book

Software Test Design details best practices for testing software applications and writing comprehensive test plans. Written by an expert with over twenty years of experience in the high-tech industry, this guide will provide you with training and practical examples to improve your testing skills. Thorough testing requires a thorough understanding of the functionality under test, informed by exploratory testing and described by a detailed functional specification. This book is divided into three sections, the first of which will describe how best to complete those tasks to start testing from a solid foundation. Armed with the feature specification, functional testing verifies the visible behavior of features by identifying equivalence partitions, boundary values, and other key test conditions. This section explores techniques such as black- and white-box testing, trying error cases, finding security weaknesses, improving the user experience, and how to maintain your product in the long term. The final section describes how best to test the limits of your application. How does it behave under failure conditions and can it recover? What is the maximum load it can sustain? And how does it respond when overloaded? By the end of this book, you will know how to write detailed test plans to improve the quality of your software applications.

The first draft of a feature specification

Remember the five requirements we received from the product owner? While they seemed to describe the feature well enough, they are nowhere near sufficient to cover all the previous considerations. Remember, this is for three new pages – login, signup, and password reset – that provide no additional functionality. After considering all the aspects of the feature described previously, we can complete a draft of the specification. This is included in Appendix, Example Feature Specification, which shows a good first draft for a feature specification. Note how the requirements are independent, implementation agnostic, and specific.

This book aims to help you quickly produce specifications like this for the features you are testing. The same considerations crop up repeatedly in different forms, so it’s a case of learning them and applying them to your system while watching out for special cases.
