src prop warning in unit testing react testing library
Avi-Cohen-Nehemia opened this issue · comments
I'm displaying an svg by passing a src
using an import and everything works ok. Here is a simplification of my code:
import Logo from '../../assets/images/logo.svg';
const Example = () => {
...some code
return (
<ReactSVG
data-testid="export-logo"
src={Logo}
/>
);
};
However, in my unit tests (using react testing library) I get a console.error
with the meesage:
Warning: Failed prop type: The prop `src` is marked as required in `ReactSVG`, but its value is `undefined`.
The debug output shows the following:
<div data-testid="export-logo">
<div>
<div data-src="undefined" src="" />
</div>
</div>
I tried looking in past issues for a solution or maybe if I need to do some sort of mocking but couldn't find a reference to this problem except on this stackoverflow question from 2 years ago which remains unanswered.
Would appreciate any help,
cheers 🙏🏼
Hi @Avi-Cohen-Nehemia. That import
looks interesting - src
expects a string
, it uses that to make an XHR request for the SVG under the hood.
If you're looking for ways to mock those XHR requests, there are examples in this library that you may find useful, e.g. browser-spec.tsx.
