Agile Testing: A Practical Guide for Testers and Agile Teams

Our Audience

This book will help you if you’ve ever asked any of the following excellent questions, which we’ve heard many times:

If developers are writing tests, what do the testers do?

I’m a QA manager, and our company is implementing agile development (Scrum, XP, DSDM, name your flavor). What’s my role now?

I’ve worked as a tester on a traditional waterfall team, and I’m really excited by what I’ve read about agile. What do I need to know to work on an agile team?

What’s an “agile tester”?

I’m a developer on an agile team. We’re writing code test-first, but our customers still aren’t happy with what we deliver. What are we missing?

I’m a developer on an agile team. We’re writing our code test-first. We make sure we have tests for all our code. Why do we need testers?

I coach an agile development team. Our QA team can’t keep up with us, and testing always lags behind. Should we just plan to test an iteration behind development?

I’m a software development manager. We recently transitioned to agile, but all our testers quit. Why?

I’m a tester on a team that’s going agile. I don’t have any programming or automation skills. Is there any place for me on an agile team?

How can testing possibly keep up with two-week iterations?

What about load testing, performance testing, usability testing, all the other “ilities”? Where do these fit in?

We have audit requirements. How does agile development and testing address these?

If you have similar questions and you’re looking for practical advice about how testers contribute to agile teams and how agile teams can do an effective job of testing, you’ve picked up the right book.

There are many “flavors” of agile development, but they all have much in common. We support the Agile Manifesto, which we explain in Chapter 1, “What Is Agile Testing, Anyway?” Whether you’re practicing Scrum, Extreme Programming, Crystal, DSDM, or your own variation of agile development, you’ll find information here to help with your testing efforts.

A User Story for an Agile Testing Book

When Robin Dymond, a managing consultant and trainer who has helped many teams adopt lean and agile, heard we were writing this book, he sent us the user story he’d like to have fulfilled. It encapsulates many of the requirements we planned to deliver.

Acceptance conditions:

• My concerns and fears about losing control of testing are addressed.

• My concerns and fears about having to write code (never done it) are addressed.

• As a tester I understand my new value to the team.

• As a tester new to Agile, I can easily read about things that are most important to my new role.

• As a tester new to Agile, I can easily ignore things that are less important to my new role.

• As a tester new to Agile, I can easily get further detail about agile testing that is important to MY context.

Were I to suggest a solution to this problem, I think of Scrum versus XP. With Scrum you get a simple view that enables people to quickly adopt Agile. However, Scrum is the tip of the iceberg for successful agile teams. For testers who are new, I would love to see agile testing ideas expressed in layers of detail. What do I need to know today, what should I know tomorrow, and what context-sensitive things should I consider for continuous improvement?

We’ve tried to provide these layers of detail in this book. We’ll approach agile testing from a few different perspectives: transitioning into agile development, using an agile testing matrix to guide testing efforts, and explaining all the different testing activities that take place throughout the agile development cycle.
