Testing

• Learn how to write and run unit tests for backend functionality using the Node testing suite and Postman (S4, S13, S6, S13)

• Gain experience in using the Cypress testing library with React (S4, S13, B9)

• Understand how and when to use component and end to end tests (K12, S5, S6, S13)

• Understand how to write maintainable and readable test cases (S1, S4, B3)

Deployment

• Gain experience in deploying a full-stack web application to a cloud platform (S10, S14, B3)

• Understand the differences between development, staging, and production environments (K1, K3, K8)

• Configure the necessary environment variables and settings for deployment (S10, S14, B3)

Your task this week is to deploy and test the quiz app you have completed in the previous two weeks.

Description

Before you start you need to create a testing and deployment plan. We would like you plan a testing strategy that will have broad coverage of your project. The tools we would like you to use to achieve this can include Cypress, Postman and the Node built in testing library.

We would like you to deploy both the backend and frontend of your project. Before choosing a deployment platform, consider whether your application is static or dynamic, as this will influence your choice. Here are some options to consider:

• AWS EC2 Instance

• AWS Lambda (for serverless applications)

• Heroku (easy deployment for various application types)

• GitHub Pages

• AWS S3 Bucket (suitable for static websites)

• Vercel

• Netlify

• Firebase Hosting (suitable for static and dynamic sites)

• ...

Research these options and choose the ones that best fit your project's needs, considering factors like scalability, ease of use, and cost. Remember, the goal is to understand the deployment process and the considerations involved in choosing a hosting solution.

Questions to consider

• What parts of the application logic are the most critical to cover with unit tests?

• How will you mock external dependencies (like databases or APIs) during unit testing?

• What are the key user journeys and flows within the application that must be covered by end-to-end tests?

Acceptance Criteria

• Comprehensive Test coverage including unit, integration and end-to-end tests covering critical application logic and user flows.

• Successful deployment of backend and frontend.

• Documentation clearly outlines setup, deployment, and usage instructions, including API endpoints and environmental requirements.

Stretch criteria

• GitHub Actions CI setup to run your tests when you push.

• Configure HTTPS for secure communication between the frontend and backend, using a tool like Let's Encrypt to obtain and manage SSL/TLS certificates.

This week concentrates on testing and deploying the full-stack quiz application developed over the past two weeks. The focus is on implementing comprehensive testing strategies and successfully deploying both the frontend and backend components of the application.
