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.

Continuous delivery and continuous deployment offer testers opportunities for growth

Development practices are constantly changing and as testers, we need to embrace change. One of the changes that we can experience is the move from monthly or quarterly releases to continuous delivery or continuous deployment. This move to continuous delivery or deployment offers testers the chance to learn new skills.

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.

Considering Agile Principles from a different angle

In addition to the four values, the Agile Manifesto contains twelve principles that are used as guides for all methodologies included under the Agile movement, such as XP, Scrum, and Kanban.
