The React app, and the fake web service will run concurrently.

Set up React Testing Library and Vitest

• create ./src/test-utils/testing-library-util.tsx that will be a copy of the root component

Set up MSW for mocking API calls

• pnpm i -D msw
• the msw is a mocking library which will intercept the requests and responses in the integration tests
• create ./src/mocks/handler/todoHandler.ts
• create ./src/mocks/handler/index.ts
• create ./src/mocks/server.ts
• update the ./src/setupTests.ts

Integration tests

• write integration tests for the fetch todos function of WorkTodosPage.tsx by creating ./src/pages/tests/WorkTodosPage.test.ts
• run the tests, pnpm run test, and see if the todos are rendered

React Query persist cache between tests

• the beforeEach does not work

beforeEach(() => {
  queryClient.clear();
});
