Exploratory testing is an approach to testing that is often misunderstood. Actually it is an approach to testing that emphasizes testers ability to explore an unknown object or area through concurrent test design and test execution. In order to be skillful in it, you need to have several assets that will help you reveal relevant information about the product you’re building. I will share many of the things that I consider essential for a person who wants to understand more about exploratory testing. Talk is focusing a lot on things that have evolved my thinking and therefore helped me be more valuable as a tester. Many of them are useful for anyone working in software development.

EXPLORATORY TESTING
An approach to testing that emphasizes testers ability to explore an unknown object or space through concurrent test design and test execution.
Explore = travel through (an unfamiliar area) in order to learn about it (Oxford Dictionaries)
@al3ksis
FREEDOM & RESPONSIBILITY
“A style of software testing that emphasizes the personal freedom and responsibility of the individual tester to optimize the quality of his or her work by treating test design, test execution, test interpretation, and test-related learning as mutually supportive activities that continue in parallel throughout the project.” – Cem Kaner
@al3ksis
CREATING BY REACTING
“An essential aspect of a painter's canvas and a musical instrument is the immediacy with which the artist gets something there to react to.
A canvas or sketchbook serves as an "external imagination", where an artist can grow an idea from birth to maturity by continuously reacting to what's in front of him.” – Bret Victor (Learnable Programming)

THINGS THAT HAVE HELP ME EVOLVE AS A TESTER
@al3ksis
1. QUALITY IS A RELATIONSHIP
“Quality is value to some person.” – Jerry Weinberg
“…who matter.” – James Bach & Michael Bolton
By “value,” I mean, “What are people willing to pay (do) to have their requirements met.” – Jerry Weinberg
@al3ksis
BUG FOR ONE, FEATURE FOR ANOTHER
@al3ksis
2. COMMUNICATION SKILL
@al3ksis
@al3ksis
“Agile Is Dead.”
@al3ksis
“What observation led you to that conclusion?”
@al3ksis
“What is your intention?”
“What are you trying to achieve with what you just said?”
@al3ksis
ALSO USEFUL WITH SPECIFICATIONS
Integration to System A is real-time and usually triggered by a modification from System B.
