Debugging Component Tests
Learn to debug component tests in this lesson.
We'll cover the following
A test to debug
The starter project for this lesson contains an ErrorMessage
component and a test that will be familiar from previous lessons.
test("Should render correct message when message prop passed", () => {
const { container } = render(<ErrorMessage message="test" />);
expect(screen.getByText("test")).toBeInTheDocument();
});
The difference from our previous lessons is that a container
variable has been destructured from the return value of render
. The container
function will contain a reference to the container element for the test elements. This variable isn’t useful for this test but will help us learn how to debug component tests.
