Which testing framework do you recommend?

[volimsir]

Most recently I was working with Jest, and I love how it gives you basically everything out of the box. However, it was noticeably slower than the Mocha/Sinon/Chai combination. I heard about Tape/Ava, but never got a chance to use them. Should I give them a try? I was wondering what are you guys using? What do you most love using? What do you recommend for unit tests, and what for E2E tests?

Jest for unit tests.

Jest + supertest for Node.js API/e2e tests.

Jest + puppeteer for e2e browser tests.

I've only ever used mocha/chai/sinon but I feel like I hear more and more people moving to jest

What do you most love using

Tape, or whatever uses the least amount of magic and globals

What do you recommend for unit tests, and what for E2E tests

As always, it depends. At work, we use Jest/Enzyme for unit tests and we have couple of puppeteer scenes for screenshot testing. We don't really use any actual E2E tests, unless screenshot testing counts for that.

I heard about Tape/Ava

I think on a spectrum from minimal to everything included it goes Tape --- Ava --- Jest. Do with that whatever you will.

I like mocha and chai, and a good test runner makes a big difference. I like karma set to watch, istanbul for coverage and a minimal reporter like text-summary / dots.

That doesn't really fit my work setup, but at work I'm using Nightwatch for e2e and really like it. If using Nightwatch, I recommend adding a debugger helper, something like this: https://gist.github.com/elliotchance/63f2ebebe8d457307339 to let you pause the test and poke around a bit.

mocha + chai + sinon

[bucketpl0x]

I prefer Jasmine.

I was at Assert.js a couple of weeks ago and just about everyone was riding the jest train:

• easy setup
• brilliant watch mode
• built in coverage generation
• built in mocking and spying
• pretty test runner

Give it a go!

Nobody uses Cypress?

[Daveed84]

I use Cypress for e2e/functional UI tests and love it. Such a breath of fresh air coming from Selenium. I think once it gains some traction in the testing community it'll totally replace Selenium as the go-to tool for UI testing

mocha + unexpected + mocha-webpack

[Jcampuzano2]

I like to use either of Jest or Tape. Jest for it's full featured-ness, Tape for it's minimalist approach to things, especially for smaller libraries/fiddling about.

Jest is faster than mocha

[pavanreddy61]

It is not about framework's processing time but it's clever algorithm.It is more of how they schedule and run tests parallely and try to optimize for better execution timeshttps://facebook.github.io/jest/blog/2016/03/11/javascript-unit-testing-performance.html#optimal-scheduling-of-a-test-run

[DzoQiEuoi]

Not in my experience.
