RBCS COVID-19 response: All of our public training courses through May will be run virtually (view details).
The RBCS podcast allows you to stay current on important topics in software testing and training. Subscribe for the RBCS software testing podcast and, about twice a month, you'll learn something new and interesting. Rex will share important lessons learned from RBCS' consulting, training, and expert services engagements. Listen while exercising, going for a walk, shopping, or driving, and become a more informed software tester.

Shift left. Continuous integration and continuous delivery (CI/CD). Continuous deployment. DevOps. What is all this stuff and what does it mean for you as the tester? In this keynote, Rex Black will explain these concepts and their test implications. He’ll then describe the emerging role of the SDET (Software Development Engineering in Test, also called SET) and what SDETs do. Yes, being an SDET is about test automation, but it’s about a lot more than that, and Rex will give you some examples of things you can expect to do as an SDET in a shift left world over the coming decade. Don’t worry. Life as a tester in the SDET reality is gonna be fun and exciting, and Rex will give you some ideas how.

You know that testing and quality is important, right? Okay, prove it. Exactly how much money do you think testing saves? Yes, that’s right saves. Testing is often thought of as a regrettable cost center, something that must be funded to avoid some dimly-understood “bad stuff that could happen.” In fact, software testing and other quality assurance activities save money. Typically, every dollar spent on testing saves eight dollars in the long run. In this One Key Idea session, Rex will demonstrate the use of cost of quality, a technique known for over 50 years, using a real world case study and a spreadsheet you can download and use that same day. Testers, know your value!

In just a few years, mobile devices and the applications on them have upended the way people use computers. People spend more time than ever on their PCs, but people spend even more time on their mobile devices. Obviously, mobile devices and apps have important differences from their PC counterparts. It’s not just a smaller screen! However, does that mean that all proven best practices for testing and quality go out the window when dealing with mobile apps? In this webinar, Rex will explain what changes, and what doesn’t change, when you move into the mobile world.

Agile methods have become widespread over the last 20 years, but it’s taken a while for testing to catch up. However, Agile testing best practices have emerged, and the ISTQB Agile Working Group has taken on the task of capturing those for you. In this brief webinar, Rex Black, Chair of the ISTQB Agile Working Group, will explain where the program has been, where it is now, and how it is evolving to support Agile testers in their careers. In twenty minutes or less, you’ll learn how the ISTQB Agile syllabi can help you advance your career as an Agile tester.

If you have been in software engineering for a while—or in fact just in the working world in general for a while—you’ve probably seen someone do something stupid with metrics. Such mistakes raise a whole bunch of interesting questions. What are the most common metrics mistakes? Why are they mistakes? Why do people make these mistakes? Are you making these mistakes? Why use metrics at all, when there are so many mistakes? In this talk, Rex will give real-world examples of these mistakes, explain the management and economic theories behind metrics, and help you find ways to implement metrics that aren’t stupid.

In our inaugural One Key Idea session, we looked at how use pairwise testing to examine combinations of inputs, configuration values, types of data, and the like. This is a great technique when the interaction between these factors is unpredictable. However, in some cases, specific business rules govern these interactions. How can we model these business rules and use that model to develop a reasonable set of tests? Simple: decision tables. In this One Key Idea session, Rex will explain the basics of this fundamental technique. In twenty minutes or less, you’ll learn how to create and use these straightforward, table-based representations of business logic in your daily work.

If you are testing a simple mobile app, you may find it relatively easy to find representative test data. However, what if you are testing enterprise scale applications? In the enterprise data center, one hundred or more applications of various sizes, complexity, and criticality co-exist, operating on various data repositories, in some cases shared data repositories. In some cases, disparate data repositories hold related data, and the ability to test integration across applications that access these data sets is critical. In this keynote speech, Rex Black will talk about the challenges facing his clients as they deal with these testing problems. You’ll go away with a better understanding of the nature of the challenges, as well as ideas on how to handle them, grounded in lessons Rex has learned in over 30 years of software engineering and testing.

One important way to test software is based on the way it’s supposed to work, verifying conformance to specified behavior from user stories and requirements, and validating that the software solves the users’ and customers’ problems. This is often called black-box testing. However, another way to test software is based on the way it’s built, which is the complementary concept of white-box testing. We measure completeness of black-box testing through coverage of requirements, user stories, risks, personas, and more, and we measure completeness of white-box through code coverage. In this One Key Idea session, Rex will explain the meat-and-potatoes of code coverage, statement coverage and branch coverage, and demonstrate these concepts with a free tool, gcov. Technical and non-technical testers alike will walk away with a clearer understanding of this critical concept.

Archimedes once wrote, “Give me a place to stand, and a lever long enough, and I will move the world.” In Agile, the place to stand is testing, and the lever is test automation. Are you using all the leverage that lever gives you? Most organizations are missing some tricks, and not getting the full value of test automation. In this webinar, Rex will survey all the different ways you can—and should—take advantage of test automation as an Agile tester. The best news: Many of these forms of automation involve tools that won’t cost you a dime! Spend some time learning about some high-ROI, proven best practices to reduce failure costs and increase quality.

If you’ve been testing for any length of time, you know that the number of possible test cases is enormous if you try to test all possible combinations of inputs, configuration values, types of data, and so forth. It’s like the mythical monster, the many-headed Hydra, which would sprout two or more new heads for each head that was cut off. Two simple approaches to dealing with combinatorial explosions such as this are equivalence partitioning and boundary value analysis, but those techniques don’t check for interactions between factors. A reasonable, manageable way to test combinations is called pairwise testing, but to do it you’ll need a tool. In this inaugural One Key Idea session, Rex will demonstrate the use of a free tool, ACTS, built by the US NIST and available for download worldwide. We can’t promise to turn you into Hercules, but you will definitely walk away able to slay the combinatorial Hydra.
