One Key Idea: Performance Testing

Length: 0h 25m 8s
Download (20.3 MB)


Performance testing is easy, right?  Grab a tool, record a transaction with the server, ramp up a thousand virtual users...  What do you often get?  A hot mess!  Performance testing is likely the kind of testing most likely to be done poorly.  It does not have to be that way.  Join us to learn what performance testing is not: not easy, not guaranteed, but not impossible to do well.  Much of a good performance testing program is not about using the tool at all; instead it includes all of the ISTQB buzzwords: static testing, early testing, planning and preparation.  Learn the basics of successful performance testing and improve your performance test project.

One Key Idea: ISTQB Advanced Security Tester

Defects and errors prevent applications and systems from delivering the value their designers and customers intended.  Moreover, defects and errors present opportunities for malicious actors to undermine the integrity, availability and confidentiality of essential business data and computational assets.  Many large cyber incidents (ex. Target, Yahoo! and Equifax) have reduced the tolerance of regulators, shareholders, customers and the public for poor cyber security practices.  The greatest threat is directed towards the greatest value, albeit the path of attack may be roundabout.  Security testing is an essential phase in the application and systems development and operations lifecycle.  Join us to learn about this valuable professional development step that will bolster your career, and assist your employer’s efforts to take substantive steps to ensure their business goals are reached and risks managed.

Fully Leveraging Agile Test Automation

Length: 1h 4m 17s

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.

The Down Part of “Shift Left and Down”

Length: 1h 3m 36s
Download (71.1 MB)


Shifting defect discovery to earlier activities (Shift Left) reduces rework and improves quality deliveries to customers. A lot of attention is paid to this part of “Shift Left and Down”, but how do we do the Shift Down? Root Cause Analysis (RCA) is the answer. A variety of techniques can be used with varying formalities, cost, and results; ranging from informal, 5-why, Ishikawa/fishbone to Cause-Effect.  Which technique is the right one to use, and when should it be applied? Is your organization ready for RCA? What do you do with the results? These questions and others will be discussed by Ed Weller, who will draw on 20 years of experience using RCA and onsite training across a wide range of businesses.

Enterprise Challenges of Test Data Management

Length: 1h 3m 33s
Download (71 MB)


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 webinar, 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.
