Testing

• Learn how to write unit tests, integration tests, and end-to-end tests using testing frameworks like Cypress (K12, S4, S5, S13)

• Understand the importance of code organisation, modularity, and reusability (K7, S1, S11)

• Solidify typescript skills (K7, S1, S11, S12)

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

Deployment

• Understand the concept of infrastructure as code (K1, K5, K7)

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

• Understand the basic syntax of provisioning resources with AWS CDK (S10, S14, S16)

• Have good working understanding of the permissions involved when deploying on AWS, (i.e security groups) (K8, B5)

• An example of the process of setting up a CDK project

Project

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

Spike

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 also like you to deploy this project using an EC2 instance for you server and a S3 bucket to serve your static files.

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 on an AWS.

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

Stretch

• GitHub Actions CI setup to automatically re-deploy when you push to main.

This week focuses on testing, deployment, and optimization of the e-commerce web application developed over the past two weeks. The emphasis is on implementing comprehensive testing strategies, deploying the full-stack application to AWS, and setting up continuous integration and deployment pipelines.

Workshops

• .NET

Execute Program

• Finish previous courses

Topics

• Writing and organizing unit tests, integration tests, and end-to-end tests

• Mocking external dependencies in tests

• Understanding and configuring different deployment environments (development, staging, production)

Project

• Develop a comprehensive testing strategy for the e-commerce application

• Implement tests using Cypress, Postman, and Node's testing library

• Create a deployment plan for AWS infrastructure

Stretch Goals

• Set up a GitHub Actions CI/CD pipeline for automatic deployment on push to main

• Implement staging environments in addition to development and production

• Optimize application performance for production environment

Additional Skills

• Code organization and modularization for testability

• Advanced TypeScript usage in testing and deployment scripts

• Understanding of cloud architecture and best practices

This week brings together all aspects of the software development lifecycle, from testing to deployment, providing a holistic view of bringing a web application to production. It emphasizes the importance of thorough testing, secure and scalable deployment practices, and the use of modern DevOps tools and techniques.
