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.

UX and loading

You should combine UX testing with load testing to check the behavior in the worst cases. While response times and pages may be acceptable under light load, this could be very different when the system is busier. See Chapter 12, Load Testing, for more details. Loading issues can manifest in several ways.

The most obvious is lists that grow in size. If there’s a page or a menu with a list of items that can increase over time, such as users or customers, ensure you have proper pagination and searching in place. When the lists are short, you can get away with loading and displaying the whole thing at once, but that rapidly becomes unmanageable if your system experiences any kind of popularity and growth.

Pagination involves loading a certain number of entries, with the remainder split over other pages. The number of entries per page should be configurable, and there should be options to jump to the next and previous pages and the first and last pages. A search...
