In a React project that uses Jest and Testing Library, after adding some ProgressBar circles, the tests started to fail. I believe it is due to JSDom not supporting SVG.
The error I'm receiving is:

The React widget code to draw the circle is below:
import React, { useEffect, useMemo, useCallback } from "react";
import { Circle } from "progressbar.js";
const ProgressCircle = ({ level, animate }) => {
var wrapper = document.createElement("div");
wrapper.className = "progressBarDiv";
wrapper.style = "height:50px;display:flex;flex-direction:column";
wrapper.id = level;
var percentage = Math.round(animate * 100);
var color = "#7F00FF";
if (percentage >= 80) {
color = "#00FF00";
} else if (percentage >= 50) {
color = "#003FFF";
}
const bar = useMemo(
() =>
new Circle(wrapper, {
strokeWidth: 6,
easing: "easeInOut",
duration: 1400,
color: color,
trailColor: "#888",
trailWidth: 1,
step: function (state, circle) {
circle.setText(percentage + "%");
},
}),
[]
);
const node = useCallback((node) => {
if (node) {
node.appendChild(wrapper);
}
}, []);
useEffect(() => {
bar.animate(animate);
}, [animate, bar]);
return <div ref={node} />;
};
export default ProgressCircle;
As a workaround, I added this code to check if the userAgent has "jsdom" in it, and just return a blank div instead of drawing.
// Don't try to draw anything if the user agent reports "jsdom",
// since Jest/Testing Library using jsdom cannot draw SVGs and this breaks the
// ProgressBar.js library.
var userAgent = window.navigator.userAgent;
if (userAgent !== undefined) {
if (userAgent.search("jsdom") >= 0) {
return <div />;
}
}
Would it be possible to add some validation on the path value. In this case, it was the in the Path function in path.js:
var Path = function Path(path, opts) {
// Throw a better error if not initialized with `new` keyword
if (!(this instanceof Path)) {
throw new Error('Constructor was called without new keyword');
}
// Default parameters for animation
opts = utils.extend({
delay: 0,
duration: 800,
easing: 'linear',
from: {},
to: {},
step: function() {}
}, opts);
var element;
if (utils.isString(path)) {
element = document.querySelector(path);
} else {
element = path;
}
// Reveal .path as public attribute
this.path = element;
this._opts = opts;
this._tweenable = null;
// Set up the starting positions
var length = this.path.getTotalLength();
this.path.style.strokeDasharray = length + ' ' + length;
this.set(0);
};
