For this project, I'm making the call using the httr (v 1.3.1) package in R.

The documentation for the API call seems pretty good, and provides a few examples; unfortunately, none of these examples utilize R and, since I know very little about API development, I'm unsure how the "content" of the documentation should translate to me. The documentation provides the following example:

I've got an onChange handler on an input that I'm trying to test based on what I've read in the Dom Testing Library docs here and here.

Ultimately, the value for the input is received as a prop by the component and the input value is updated.

I'm mocking the props and trying to do a few simple tests to prove that the onChange handler is working as expected.
