Quick Guide To Drupal Testing

Dries Buytaert, a graduate student at the University of Antwerp, came up with the idea of developing something similar to a chat room. Moreover, he modified the conventional chat rooms into a website where his friends could post their queries and reply through comments. However, for this project, he thought of creating a temporary archive of posts.

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.

QA Innovation &#8211; Using the senseshaping concept to discover customer needs

QA Innovation - Using the senseshaping concept to discover customer needsQA testers have a unique role and responsibility to serve the customer. Serving the customer in software testing means protecting customers from application defects, failures, and perceived failures from missing or misunderstood requirements. Testing for known requirements based on documentation or discussion is the core of the testing profession. One unique way QA testers can both differentiate themselves and be innovative occurs when senseshaping is used to improve the application user experience.
