The Art of Testing the Untestable

It’s strange to hear someone declare, “This can’t be tested.” In reply, I contend that everything can be tested. However, one must be pleased with the outcome of testing, which might include failure, financial loss, or personal injury. Could anything be tested when a claim is made with this understanding?

Test strategy and how to communicate it

I routinely come across test strategy documents when working with customers. They are lengthy—100 pages or more—and packed with monotonous text that is routinely reused from one project to another. Yawn once more— the test halt and resume circumstances, the defect management procedure, entrance and exit criteria, unnecessary generic risks, and in fact, one often-used model replicates the requirements of textbook testing, from stress to systems integration.

The Core Principles of Scrum

Two-phase Model-based Testing

Most test automation tools just do test execution automation. Without test design involved in the whole test automation process, the test cases remain ad hoc and detect only simple bugs. This solution is just automation without real testing. In addition, test execution automation is very inefficient.

What is coaching leadership

Coaching is a term that is now being mentioned a lot more in the leadership space. Having grown successful teams I thought that I was well acquainted with this subject.
