The buck doesn't stop with vibrant number of frameworks for development but also for test development frameworks in Node/Javascript ecosystem. Testing in JavaScript is becoming expected by developers more and more. But where do you start? There are so many framework choices out there. It can feel pretty overwhelming. I found commonly used libraries, Chai and Sinon, that are often used in conjunction with Jasmine and Mocha. What would be a preferred choice considering easier start with 2 developers on roll and consistent long term benefits?
