How can I set a URL for automated testing with React Testing Library?

I am trying to create an automated test for a React component, but proper function of this React component depends on URL params. How can I set up a URL for the component to live inside in the testing environment (Jest, for example)? Or am I approaching this the wrong way, because I'd think that this would be somewhat of an easy answer to find on the web but thus far I've come up empty.
