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.

Stress Testing

“OVERWORK, n. A dangerous disorder affecting high public functionaries who want to go fishing.”

– Ambrose Pierce, The Devil’s Dictionary

We now come to the final form of testing considered in this book: stress testing. These are some of the hardest tests to run and the most stringent checks on your application. Stress testing is a combination of testing load and error cases, as you push your system beyond its limits.

In the last chapter, we considered load testing, which ensured an application could perform up to its required performance. If a website can handle 10,000 simultaneous users, testing must reach that number without seeing a degraded performance. The pass mark for these tests isn’t just completion, but also the time taken for each action. Stress testing comes next, going beyond system limits.

How does your application cope when the 10,001st user attempts to join, a user tries to extend their connection beyond...
