What will come after “agile”?

I think that probably most development teams describe themselves as being “agile” and probably most development teams have standups, and meetings called retrospectives.There is also a lot of discussion about “agile”, much written about “agile”, and there are many presentations about “agile”. A question that is often asked is what comes after “agile”? Many testers work in “agile” teams so this question matters to us.

And the Winner Is: Aggregate Model-based Testing

In my last blog, I investigated both the stateless and the stateful class of model-based testing. Both have some advantages and disadvantages. You can use them for different types of systems, depending on whether a stateful solution is required or a stateless one is enough. However, a better solution is to use an aggregate technique that is appropriate for each system. Currently, the only aggregate solution is action-state testing, introduced in the book Paradigm Shift in Software Testing. This method is implemented in Harmony.

Testing in Production: A Detailed Guide

When most firms employed a waterfall development model, it was widely joked about in the industry that Google kept its products in beta forever. Google has been a pioneer in making the case for in-production testing. Traditionally, before a build could go live, a tester was responsible for testing all scenarios, both defined and extempore, in a testing environment. However, this concept is evolving on multiple fronts today. For example, the tester is no longer testing alone. Developers, designers, build engineers, other stakeholders, and end users, both inside and outside the product team, are testing the product and providing feedback.

How To Automate Toggle Buttons In Selenium Java

If you pay close attention, you’ll notice that toggle switches are all around us because lots of things have two simple states: either ON or OFF (in binary 1 or 0).
