Visual Regression Testing with Jest

This is a walkthrough of how to set up Visual Regression Testing with Jest for an application created with create-react-app.

The following walkthrough uses React as an example, but the approach should work for any modern frontend library! I assume it can be used with Angular, Vue, Cycle.js and more.

This gist walks you through a create-react-app application as an example of how to set up Visual Regression Testing in Jest using libraries I wrote recently which enable this: jsdom-screenshot, jest-transform-css and jest-transform-file.

Convert Stylus to SASS

Here's how I converted a whole batch of Stylus files to SASS without using a converter (none exist, that I'm aware of), converting each Stylus file manually, or programming my own Stylus->SASS converter, which would have entailed building a parser, and then generate SCSS from the AST.

First, grab sandr.py here: https://github.com/jfgiraud/sandr

Then, in the directory of your Stylus files, run (if you have multiple directory levels, you can do similar task using find):

for file in *.styl; do echo "/*! FILENAME: $file */" >tempfile; cat $file >>tempfile; mv tempfile $file; done

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

youtube-dl hook script for mpv

Now part of mpv

As of 079ecd7 (2014-11-19), the hook script is now integrated into mpv and will be avaiblable when compiled with LUA support. It is (currently) disabled by default, to enable it add --ytdl=yes to your command-line or ytdl=yes to your mpv.conf.

Open Issues

• automatic selection of ASS subformat (rg3/youtube-dl#4019)
• youtube-dl may get stuck on direct URLs to less popular file types (m2ts) (rg3/youtube-dl#4149)
