Getting a warning when running test on svg component. It's not causing the test to fail but trying to get it cleaned up. Using SVGR to use svg files as react components. I believe the issue is Jest isn't able to see the svgr configuration in webpack, but not sure how to fix it.
Warning
console.error
Warning: <ReactComponent /> is using incorrect casing. Use PascalCase for React components, or lowercase for HTML elements.
