This was a very clear thought out way to explain exploratory testing. I will be using this as one of my reference guides from here on out.

There are two chapters being written yet, but the book is just awesome!

The best book I've read about testing until today.

I really recommend it, specially for for developers and testers, but it could be interesting for everyone working on team that is building any kind of (software) product.

Exploratory testing has been getting press lately. Deservedly so, I should say. Still, outside of blog posts and direct interaction with those who have represented the movement of exploratory testing, there isn't a good one stop for explaining what exploratory testing is in a meaningful way. Practitioners have to scratch around and try out a number of different sources and models and deal with a lot of "it depends". Getting all of the details in one place, and with a smooth narrative that can he ...more

Excellent summary of exploratory testing and how to use it well in various environments. A book I continue to come back to, to look stuff up and get a refresher on various exploratory testing topics. Well written, this book pulls in you while teaching you a lot about how to be an effective tester.

I read this book with a group and enjoyed discussing each chapter. I was hoping to find more advice on how to get a team to support me in exploratory testing but I guess I am on my own for that. I found most of the content applicable and helpful. I have certainly gained a stronger understanding of exploratory testing and how to better approach it in the future.
The book talks about exploratory approach to testing wherein we explore the subject at and around "boundaries" to figure out how the subject performs at and around "boundaries". The book provides good strategies to process to conduct exploratory testing along with exploration strategies specific to different kinds of boundaries. If you write tests on a day to day basis and benefit from them, most of the content may seem like "been there done that" or "I agree". However, if you are skeptical abou ...more

There are hundreds of books on Software Testing. All of them have similar table of contents - Introduction to Testing, Testing Types, Testing Methodologies, Testing Techniques, Approaches, Strategies, Reporting, Test Management etc. I am not criticizing these books, they are good on their part. However, these books limit the Exploratory Testing in few paragraphs or within a chapter at max. Explore It! by Elisabeth Hendrickson complements all these books and teach the Exploratory Testing "in deta ...more

Inspiring. The best book I've read all year. This is going to make me a better tester.

There is checking. This is when you test to make sure your project does what it was designed to do under the best conditions.

Then there is exploring. This is when you test to make sure there is no risk. This is where many of us fall woefully short. Reading this book made me realize I need to step it up. But Exploring is the fun part of testing. It's why I became a tester.

I am excited to begin implementing what

This is a quick read and offers some sensible approaches to exploratory software testing. There's no great insights, and personally I don't feel I'm going to approach testing any differently as a result of this book, but it certainly contains information that others may find helpful. ...more

A well written, and engaging, read. It would suit testers, programmers, and product owners and would provide insight into how to explore applications, or specifications to ensure a good quality result.

First real book on exploratory testing I found. I like it is short , concrete and with real life examples. Not perfect, because it may not give you much if you have some experience in this area. But really good for everyone who is new in exploratory testing.

An amazing book on exploratory software testing. I wish it was written when I was starting my career.

This is a great book for testers of all experience levels. New testers will get exposure to some excellent foundations. Experienced testers will get a refresher, and maybe even a few new ideas.

Another great book from Pragmatic Programmers that is worth reading whether you are in management, software development, analysis or testing. The thoughts are well laid out, the author is personable, the chapters are organized well, and lots of real world examples are provided from specific projects.

In my years of working in software development I have noticed to paths testers take. Chaotic, where they initially try to break the system with the most extreme choices they can, and spec testers tha

Testing can be more than just following a script. When the basic functions work one can start with tests that are not formalized (jet) to figure out how wide the happy path really is. Often enough a minor difference in the input and a webpage or a parser no longer works as expected. Problems like those will not be found by regular testing and need therefore a different approach. Elisabeth Hendrickson explains in this book what exploratory testing is, how you should time box your explorations and ...more

This was a great read. It is well written and easy to follow and engaged the side of me that gets excited about testing. It exposed the methods that should be being applied for both exploratory testing and to help scope the projects themselves.

I use to hate exploratory testing : a loosy way to critique a product once the job is done. An undisciplined, freestyle and out of control prcatice. Tester working this way fell free to ignore the specification and rewite / re-think the way the system should behave. Honestly it's the way it works most of the time.
Then comes this book.
The way exploratory testing is exposed here have nothing to do with the former description : it's focused, planed, disciplined and it takes the best of the tester's
