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.

Advantages, disadvantages, and alternatives to feature specifications

Precisely describing your features has many advantages, but specifications can be neglected due to the time they take to write. The onus can fall on testers to prepare these specifications since they need to know how the product will work in practice. If no one else has written a description by the time the feature reaches you, it may be up to you to prepare it. Despite its downsides, preparing a feature specification is well worthwhile, as described in the following table:




Early chance to find bugs in the requirements

Takes time to prepare

Avoids surprises for developers and testers

No immediate payback

Saves time by avoiding misunderstandings
