Critical thinking is the kind of thinking that specifically looks for problems and mistakes. Regular people don't do a lot of it. However, if you want to be a great tester, you need to be a great critical thinker, too. Critically thinking testers save projects from dangerous assumptions and ultimately from disasters. The good news is that critical thinking is not just innate intelligence or a talent—it's a learnable and improvable skill you can master. Michael Bolton shares the specific techniques and heuristics of critical thinking and presents realistic testing puzzles that help you practice and increase your thinking skills. Critical thinking begins with just three questions—Huh? Really? and So?—that kick start your brain to analyze specifications, risks, causes, effects, project plans, and anything else that puzzles you. Join Michael for this interactive, hands-on session and practice your critical thinking skills. Study and analyze product behaviors and experience new ways to identify, isolate, and characterize bugs. 

Traditional test plans are incompatible with agile software development because we don't know all the details about all the requirements up front. However, in an agile software release, you still must decide what types of testing activities will be required—and when you need to schedule them. Janet Gregory explains how to use the Agile Testing Quadrants, a model identifying the different purposes of testing, to help your team understand your testing needs as you plan the next release. Janet introduces you to alternative, lightweight test planning tools that allow you to plan and communicate your big picture testing needs and risks. Learn how to decide who does what testing—and when. Determine what types of testing to consider when planning an agile release, the infrastructure and environments needed for testing, what goes into an agile “test plan,” how to plan for acquiring test data, and lightweight approaches for documenting your tests and recording test results.

Exploratory testing is an approach to testing that emphasizes the freedom and responsibility of testers to continually optimize the value of their work. It is the process of three mutually supportive activities done in parallel: learning, test design, and test execution. With skill and practice, exploratory testers typically uncover an order of magnitude more problems than when the same amount of effort is spent on procedurally scripted testing. All testers conduct exploratory testing in one way or another, but few know how to do it systematically to obtain the greatest benefits. Even fewer can articulate the process. Jon Bach looks at specific heuristics and techniques of exploratory testing that will help you get the most from this highly productive approach. Jon focuses on the skills and dynamics of exploratory testing, and how it can be combined with scripted approaches.

The nature of exploration, coupled with the ability of testers to rapidly apply their skills and experience, make exploratory testing a widely used test approach—especially when time is short. Unfortunately, exploratory testing often is dismissed by project managers who assume that it is not reproducible, measurable, or accountable. If you have these concerns, you may find a solution in a technique called session-based test management (SBTM), developed by Jon Bach and his brother James to specifically address these issues. In SBTM, testers are assigned areas of a product to explore, and testing is time boxed in “sessions” that have mission statements called “charters” to create a meaningful and countable unit of work. Jon discusses—and you practice—the skills of exploration using the SBTM approach. He demonstrates a freely available, open source tool to help manage your exploration and prepares you to implement SBTM in your test organization.
