Wow, just now seeing this topic. I work for a cloud company hosted in AWS. We started out, Netflix/Spotify style microservices. We were all on ec2 images generate by packer (and later with AWS Image Factory). When Docker hit, we kicked the tires but never did anything with it beyond using it for running unit tests, and later, infrastructure tests. 5 years ago, during a hackathon, our little group began...

> Why not? Most people won't spend the time to learn OS/distro building. I don’t know how good they are and have never used any, but there’s tooling for building the ultimate stripped down kernel, unikernels (https://en.wikipedia.org/wiki/Unikernel) A quick Google gives me https://nanovms.com/, https://github.com/solo-io/unik and https://github.com/rumpkernel/rumprun. - Source: Hacker News / about 3 years ago

Great entrant in the space that is actually usable: https://www.unikraft.org Promising project that's inactive but was one of the first ones I found with reasonable ergonomics and no lock-in to a specific language that I didn't use: https://github.com/rumpkernel/rumprun Unfortunately it looks to be unmaintained as of now, but I expect the examples still work etc (https://github.com/rumpkernel/rumprun/issues/135). - Source: Hacker News / over 3 years ago

Then there is the rumprun unikernel (that runs on qemu and baremetal x86), the sources of which you can find here https://github.com/rumpkernel/rumprun (and some more projects in the github org: https://github.com/rumpkernel). These projects have not been actively maintained for many years. Source: almost 4 years ago

I am very comfortable with Minitest in Ruby. When I started to learn Rails, though, I was surprised by how different RSpec was. In case .NET testing is equally unlike the xUnit style, I should learn the idioms. - Source: dev.to / about 2 months ago

It supports both RSpec and Minitest as well as any other testing gem. There are flexible configurations options which allow to configure editor with needed testing tool. - Source: dev.to / 6 months ago

I'm a huge supporter for TDD(Test Driven Development). Almost every piece code should be tested. During my co-op more than half of the time I spent writing test for my PR. I believe that experience really helped me understand the necessity of testing. I was surprised to see how similar the testing framework in JS and Ruby are. I used Jest which is very similar to RSpec I have used during my co-op. To mock http... - Source: dev.to / 6 months ago

The describe and it keywords are popularly used in other JavaScript testing frameworks to write and organize unit tests. This style originated in Ruby's Rspec testing library and is commonly known as spec-style testing. - Source: dev.to / 9 months ago

5. Automated Tests: Unit tests are automated tests that verify the behavior of a small unit of code in isolation. I like to write unit tests for every bug reported by a user. This way, I can reproduce the bug in a controlled environment and verify that the fix works as expected and that we wont see a regression. There are many different JavaScript test frameworks like Jest, cypress, mocha, and jasmine. We use... - Source: dev.to / 10 months ago
