Test Design

Large-scale and complex testing projects can stress the testing and automation practices we have learned through the years, resulting in less than optimal outcomes. However, a number of innovative ideas and concepts are emerging to better support industrial-strength testing for big projects. Hans Buwalda shares his experiences and strategies he's developed for organizing and managing testing on large projects. Learn how to design tests specifically for automation, including how to incorporate keyword testing and other techniques.

The practice of agile software development requires a clear understanding of business needs. Misunderstanding requirements causes waste, slipped schedules, and mistrust within the organization. Jared Richardson shows how good acceptance tests can reduce misunderstanding of requirements. A testable requirement provides a single source that serves as the analysis document, acceptance criteria, regression test suite, and progress-tracker for any given feature. Jared explores the creation, evaluation, and use of testable requirements by the business and developers.

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—learning, test design, and test execution—done in parallel. 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.

As the need for testing mobile applications increases, so does the need to understand and apply test practices that cover more than just functional correctness. Randy Rice leads you through techniques for designing the right tests for your mobile applications, whether they are on the device or on a website. Learn how to know which items of functionality are important to test based on relative risk. Randy presents his visual method of how to rank important attributes including usability, compatibility, accessibility, and security, and then how to design tests for them.

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. 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.

In both agile and traditional projects, keyword-driven testing—when done correctly—has proven to be a powerful way to attain a high level of automation. Many testing organizations use keyword-driven testing but aren't realizing the full benefits of scalability and maintainability that are essential to keep up with the demands of testing today's software. Hans Buwalda describes the keyword approach, and how you use it to can meet the very aggressive goal that he calls the "5 percent challenge"―automate 95 percent of your tests with no more than 5 percent of your total testing effort.
