Test Optimization for Continuous Integration

“Test frequently and early.” If you’ve been following my testing agenda, you’re probably sick of hearing me repeat that. However, it is making sense that if your tests detect an issue soon after it occurs, it will be easier to resolve. This is one of the guiding concepts that makes continuous integration such an effective method. I’ve encountered several teams who have a lot of automated tests but don’t use them as part of a continuous integration approach. There are frequently various reasons why the team believes these tests cannot be used with continuous integration. Perhaps the tests take too long to run, or they are not dependable enough to provide correct results on their own, necessitating human interpretation.

Complete Guide To Styling Forms With CSS Accent Color

The web paradigm has changed considerably over the last few years. Web 2.0, a term coined way back in 1999, was one of the pivotal moments in the history of the Internet. UGC (User Generated Content), ease of use, and interoperability for the end-users were the key pillars of Web 2.0. Consumers who were only consuming content up till now started creating different forms of content (e.g., text, audio, video, etc.).

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.

Why Agile Teams Have to Understand How to Analyze and Make adjustments

How do we acquire knowledge? This is one of the seemingly basic but critical questions you and your team members must ask and consider. We are experts; therefore, we understand why we study and what we should learn. However, many of us do not give enough thought to how we learn.
