Coding with @wallabyjs easily cut my development-to-complete time in half. Can't recommend it enough.— Sean Matheson (@controlplusb) April 4, 2016
Wallaby.js is one of the most absolutely awesome development tools I've ever used. Instant test feedback and editor integration, plus displaying assignment values per-line, and performance all in one. I'll never be able to live without this. https://t.co/qr8n0JeXPl— Brian Bugh (@brainbag) June 19, 2018

Been having fun with @wallabyjs and quokka. So grateful for tools that improve the quality of my dev experience 🙂— ryan (@RyanKois) February 20, 2018
I struggled for days trying to get a clean unit testing experience for Typescript. Finally tried @wallabyjs and got it working immediately and exactly what I wanted. All I do is open source dev but my time (and sanity) is well worth the price— Phil Scott (@Philco78) June 22, 2018
Just renewed my @wallabyjs license. One of the best tools I've used, would not want to code without it 😃🙏— Adrian Fâciu 🤘 (@adrianfaciu) December 4, 2018

im only writing tests because @wallabyjs is awesooome :)— Arnelle Balane (@arnellebalane) March 4, 2016
I believe that I have to mention at least once a month how freaking awesome @wallabyjs is. Been working with it for 2 years and still love it every day. Worth every penny and great support. Thx @ArtemGovorov— Brecht Billiet (@brechtbilliet) December 13, 2017
Oh yeah! We use it in every @strongbrew_io workshop so far! #tdd
For me barrier to doing TDD has always been better tooling esp in large projects, @wallabyjs however has changed that for me— Nimesh Gurung (@nimgrg) October 4, 2016
Just bought my @wallabyjs freedom licence. Its rare that a tool can have such a big impact on my workflow so quickly, I highly recommend it!— James Henry (@MrJamesHenry) July 26, 2016
the time has come to renew my @wallabyjs license. I have never spend $100 so happily. It remains my most important tool!— Dave Benjamin (@zpydee) April 6, 2017
@wallabyjs Seriously great tool, esp running only changed tests/code. I have 1000+ tests & Karma was beginning to be really slow. Thanks.— Christopher Carson (@chriscarson) December 11, 2016
Well damn, @wallabyjs is just plain awesome for JS testing and coverage. They can expect to sell us a bunch of licenses soon!— Hilke Heremans (@HHeremans) January 28, 2016
I love your work! Doing original work on a field that's been pretty much stagnant since black/green screens were cool. 🙌— Nir Benita (@NirBenita) March 29, 2017
Thank you @wallabyjs for an amazing productivity boost!— Cathal Coffey (@coffeycathal) January 27, 2016
@wallabyjs is so rapid I now find waiting about half a second for NCrunch quite tedious when switching to my C# tests.— Jamie Humphries (@_jamiehumphries) July 6, 2015
Been leaning on @wallabyjs recently. The inline symbols shown per test exposed some amazing optimisation opportunities (and a few bugs). 🤘— Sean Matheson (@controlplusb) October 30, 2017
First time of using @wallabyjs all day long at my professional work. Just DOPE! Works like a charm w/TypeScript,ES6,Mocha,Sinon,Chai,Atom.io— Jens Krause (@sectore) September 2, 2015
I just did a decently complex refactor on my JS app — and using wallaby.js made it 10x faster.— Bryan Mills (@diffkid) August 12, 2015
Just renewed my @wallabyjs and upgraded to all editors. Will it save me $70 of time this year? It will save me $70 of time *this week*!— Dave Brotherstone (@bruderstein) May 19, 2016
That moment you realise you've forgotten to start @wallabyjs and you've been wasting your time by manually running your unit tests.— Rich Somerfield (@richie5um) November 18, 2016
Most impressive JS test runner I've seen. http://t.co/93a7KYmjxC Worth a good look.— Shawn McKay (@Sh_McK) June 21, 2015
WOW.. 1 minute into @wallabyjs and I'm reeaaally impressed. Now for some Babel ES6/7 preprocessing— Einar Ingebrigtsen (@EinarI) June 18, 2015
Man, @wallabyjs is a great test runner. Good support too. 2 hours from initial bug report to them pushing a fix live. :)— Cody Hatch (@Codayus) June 17, 2015

Where can I find more information about wallaby.js, such as tutorials and samples?
You can find more information, detailed tutorials and sample project links in our documentation.
How is it different from Karma, Mocha runner, Jest CLI runner, etc.?
With other test runners you either need to run your tests manually, or, at best, configure them to run the tests when you save your source code files. Those runners either execute all of your tests or, at best, all tests in all spec files affected by all uncommitted code changes, even if you are primarily editing just one file. So, as your project grows, it takes more and more time to complete the task. The test execution results are displayed somewhere outside of your code editor, and constant context switching to view the results is a productivity killer.
Wallaby.js runs your unit tests immediately as you type, no need to run anything manually, there's even no need to save files. The tool calculates and runs the minimum required number of tests affected by your code changes, often it is just a single test - and no other testing tool is capable of operating on this level. So no matter how large your project grows - the feedback is almost instant with wallaby.js. Test execution results, including code coverage, are displayed and updated in real time right where you need it — in your code editor, next to the line of code that you're editing.
Can I use wallaby.js with Jasmine, Mocha, QUnit, AVA, or Jest?
Yes. You can use your favorite testing framework, any mocking framework (such as Sinon.js), any assertion library (such as Chai.js, Expect.js, Should.js, Jasmine built-in one, etc.) with wallaby.js. No matter how awesome and fast your testing framework is (like Jest, Mocha, Jasmine, AVA, etc.), wallaby.js makes it even more awesome and faster with the features it adds.
Does wallaby.js support Angular, React, Backbone.js, Aurelia, etc.?
What about node.js?
Wallaby.js supports node.js testing. In fact, wallaby.js is written in node.js and we write tests for wallaby.js using wallaby.js.
What about ES.next or JSX?
What about TypeScript, CoffeeScript, Flow?
What about Browserify or Webpack?
What about code preprocessors like in Karma?
Wallaby.js supports Karma-like preprocessors. Simply provide a function invoking an existing node module.
Do I have to install any standalone applications with wallaby.js?
No. All you need to install is the wallaby.js plugin for your code editor, period. No new command line tools or browser plugins. Our goal is not to add more things between you and the feedback from your tests. In fact, it's the opposite: wallaby.js eliminates any unnecessary context switching, so it's just you and your test feedback, right where and when you write your code.
Do I have to use TDD with wallaby.js or do I have to write my code first?
