Select JS testing framework

We'll use vue.js for the front-end, but we also need to unit-test it. jest is one of the options.

JS Unit testing is an interesting concept. Js Developers are using many tools such as karma , mocha, chai, sinon ... etc or even complinations of them like karma-simon-chai

As mentioned jest is the testing framework developed at Facebook, which makes testing a easier, with features like:

• Almost no config by default
• Interactive mode
• Run tests in parallel
• Spies, stubs and mocks out of the box
• Built in code coverage
• Snapshot testing
• Module mocking utilities

and within the Vuejs ecosystem, jest-vue-preprocessor and vue-jest is needed for making jest understand .vue files.

Also VueJs has, vue-test-utils the official VueJS testing library and based on avoriaz and can be using with jest

In my end the choise is Jest. One framework to rule them all and @aptiko has some initial experience on it.

I won't disagree, I think jest is nice, and if it's commonly used so much the better. Jest it is.
