            I am migrating some of my unit test cases which were previously written using Jest and Enzyme to React Testing Library. I am using Material UI's Select component and I know that, in order to open the dropdown, we have to trigger the mouseDown event on the corresponding div. Here is how I did it in Enzyme (working):

            Make sure animations are not compromising your results. If the animations change opacity or display and they did not finish before assertion from jest... it is likely to throw an error.

            The problem is as you're using ? (as in node.textContent?.match(textMatch);) the result might be undefined, while it is fine for javascript, TS sees that return nodeHasText && childrenDontHaveText; can potentially be return undefined && undefined and points out that undefined is not quite boolean. One way out of it is return nodeHasText && childrenDontHaveText || false;

            I'm pretty sure this is a design limitation of TypeScript, although I haven't found a narrowly applicable issue in GitHub. The general issue is that the heuristics TypeScript uses to check assignability between two types do not perform true unification. See microsoft/TypeScript#30134 for a discussion about the possibility of implementing such unification in TypeScript.

            The shortest example I can come up with of the problem you're facing is this:

            There are mainly 2 possibilities I see.

            1. Not waiting for the button to appear. If your button is rendered after a certain thing has finished loading, you need to wait for it to appear on the screen. You can do that with a findBy query.
