In this section, we are going to implement tests on the Page, Question, and HomePage components. React component tests can be challenging because they have dependencies, such as the browser's DOM and sometimes HTTP requests. Due to this, we are going to leverage the React Testing Library and Jest's mocking functionality to help us implement our tests.
