Jest - how to test if a component does not exist?

Question

How do I check if a component is not present, i.e. that a specific component has not been rendered?

Answer 1

If you're using react-testing-library (I know the OP wasn't but I found this question via web search) then this will work:

expect(component.queryByText("Text I care about")).not.toBeInTheDocument();

You can query by Text, Role, and several others. See docs for more info.

Note: queryBy* will return null if it is not found. If you use getBy* then it will error out for elements not found.
