React / redux testing example with Jest

I have a React application comprising mostly functional components. I haven't built it as a test-driven project because I don't know Javascript testing, but I would like to add some tests now. Because all the components are linked to the app state through redux, the tests must mock the redux store as well as test the component.

What I need is an example test suit for a single page that includes the technique for mocking the redux store as well as the basic tests for form actions. The app is built with create-react-app and therefore has Jest preinstalled. I will provide access to the Github repo for the project.
