Get started and hit the ground running in the world of software testing. This simple and practical guide teaches you the fundamentals of software testing, with no prior experience required.
You will start by learning functional and non-functional software testing. Then you will gain an understanding of the primary responsibilities of a tester in the Software Development Life Cycle and how to plan and execute testing activities. You will also learn how testing applies to an agile environment, what challenges you might face in your day-to-day life as a tester, and how to overcome them. You will learn the most commonly used test design techniques, with ample examples and exercises to practice yourself.
This book takes you on a journey around the software testing world, covering the basic principles and techniques and showing examples of how to apply them. Software testing is a safeguard of the quality of a software product, and a tester is responsible for reporting on the quality status. Keep in mind that the quality of the product is not the sole responsibility of a tester; rather, it’s a collective effort from every individual in the organization. A chain is only as strong as its weakest link. Different types of testing are applicable to every phase of the software development life cycle; of course, the priorities and the risks are not the same in all the products. Testing is all about identifying those risks and setting up a mitigation plan by executing the necessary tests and analyzing the results.
In this book, I will demonstrate some of the most important software testing types and techniques that exist and how to apply them. You will find out what testing activities take place during every phase of software development, how to plan the testing activities, how to design the test cases, how to execute them, and how to report defects and the status of your activities. It is meant to be easy to understand for everyone, even with only the slightest technical background or involvement in a product. I hope you will enjoy the process and pick up a thing or two!
By the end of this book, you will understand the software testing ecosystem, from its types, techniques, and tools, to test planning, execution, and reporting.
