Wallaby.js, the continuous test runner that outputs results directly into your editor, currently has a 20% discount on IntelliJ Platform licenses until 7th of June 2015. There are also free betas available for Visual Studio, which usually costs $100 for a single license or $160 for a company seat license.
Wallaby.js for Visual Studio is new, and it supports code coverage, smart actions, and it has font and colour options. This is what it looks like:
In that screenshot the green squares means that the source is covered by at least one test, and the pink square means the source is on the execution path of a failing test. The blog post on Visual Studio has more details and gifs for each feature.
In other Wallaby.js related news, it's recently got support for the Facebook Jest testing framework (which I've been using with React projects). You can find an example in wallaby-jest-sample.
If you're not entirely happy with Gulp and Grunt, did you know there's an older build system called Brunch? It's installable with npm (
npm install -g brunch), and the people behind it have created a new guide that makes it easy to get started.
make installed, or don't want to install it. Another reason to use Gulp or Grunt is they can provide higher-level abstractions that make reading and writing tasks easier for web developers.
brunch watch --server.
Using Brunch with an existing project might have been as much work as my Gulp/Watchify/Browserify task -- I haven't yet tried using Brunch with a big and established (OK, messy) project. I have, however, tried creating a Brunch skeleton to see what a Brunch-built project looks like, and it seems pretty good to me. If you find Gulp and Grunt hard to use then try a Brunch skeleton and take a look at the new Brunch guide.
