There may be an undiscovered tribe deep in some jungle somewhere that hasn’t made up their mind on microservices, but I doubt it. People love microservices or love to hate microservices. There’s not much in between. So it means something when even a team at a company like Uber announces a change away from microservices to something else.

You have consistently written unit tests and you have a line coverage of, let us say, 80% and all of your tests pass. Pretty good, isn’t it? But then you change your code and still all of your tests pass although you have changed code which is covered by your unit tests. In this post, we will take a look at mutation testing which will test the quality of your unit tests.

Ideally, highly-threaded I/O intensive Linux containers running on Kubernetes would have all the CPU time they need. But just how compatible is that goal with reality? To find the answer – and optimize Linux containers – application developers and DevOps teams must understand how Linux schedules tasks and allocates them CPU time. The goal behind “real-time” containers is enabling your most important containers – those with mission-critical requirements around time-sensitive performance and relia

Software testing teams use numerous types of manual testing. Each method focuses on a specific question and serves a unique purpose, so using a single form of manual testing on a project cannot be thorough enough. Choosing the right combination of manual testing types to use on each job helps testers to verify every part of the product under test, which is the key to launching high-quality products.
