jest-transformer-svg

Transform svg files for for jest+react to de-clutter snapshots.

NOTE: cloned from jest-svg-transformer since it looks unmaintained, and it doesn't support Jest versions >= 27.

Very useful with react-svg-loader. This allows you to import svgs directly into your react components, but still have nice snapshots.

Using enzyme's shallow rendering, for example:

import React from "react";
import MySvg from "../images/an-image.svg";

function MyComponent() {
  return (
    <div>
      <MySvg style={{ color: "blue" }} />
    </div>
  );
}

will result in a snapshot that looks like this:

<div>
    <SvgAnImage style={{color: 'blue'}} />
</div>

usage

This works with both enzyme and react-test-renderer.

Configure jest:

{
  "jest": {
    "transform": {
      "^.+\\.jsx?$": "babel-jest",
      "^.+\\.svg$": "jest-transformer-svg"
    }
  }
}
