In test/CustomerForm.test.js, update the import that contains blankCustomer, pulling in the new validCustomer too:import {

blankCustomer,

validCustomer,

} from "./builders/customer";

Starting at the top, modify each test that simulates a submit event. Each should be mounted with this new validCustomer object. After making these changes, run your tests and make sure they are still passing before continuing:render(<CustomerForm original={validCustomer} />);

Add a new test for submitting the form. This can go alongside the other submit tests, rather than in the validation block:it("does not submit the form when there are validation errors", async () => {

render(<CustomerForm original={blankCustomer} />);

await clickAndWait(submitButton());

expect(global.fetch).not.toBeCalled();

});
