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.

Running usability studies

A theme throughout this chapter has been the limitation of your point of view and the importance of gaining feedback from real users to find the areas that confuse them. At different times, you can use your naivety about a new feature, for instance, to play the role of a customer, but there is no escaping your experience since you work with your product so much. For that reason, getting feedback from real users is a vital part of UX testing, even more than beta testing or other types of testing the product with users.

There are many different ways to gather feedback from users, of which we will consider four key ones here: recorded sessions, questionnaires, A/B testing, and instrumentation.

Recorded sessions

Recorded sessions involve gathering volunteers and presenting them with the new feature and a task to complete. They get no other instructions but are advised to think out loud to explain what they are doing and why during the recorded session...
