An example of an AI chatbot conversation about testing strategies for MERN apps.
What are some effective testing strategies for MERN applications?
For MERN applications, consider using unit testing with Jest, integration testing with Mocha, and end-to-end testing with Cypress.
Can you explain how to set up Jest for unit testing?
Sure! First, install Jest using npm. Then, create a test file with a .test.js extension and write your test cases using the describe and it functions.
What about testing the React components?
You can use React Testing Library along with Jest to test your React components. It allows you to render components and make assertions on their behavior.
How do I handle asynchronous code in my tests?
You can use async/await in your test functions or return a promise. Jest will wait for the promise to resolve before finishing the test.
