End-to-end testing with Cypress

Matthew Casperson's blog post discusses the integration of Cypress end-to-end testing into the deployment pipeline, particularly within an Octopus deployment environment. The article highlights the challenges and solutions for running Cypress tests, emphasizing the convenience of using Docker containers over VMs for this purpose due to the pre-configured nature of Cypress Docker images. It also addresses the difficulty of mounting test scripts in Kubernetes environments and provides a workaround through Octopus worker containers, which can execute deployment steps inside Docker containers. Additionally, the post outlines the creation of a custom Docker image to run Cypress tests and demonstrates the process of executing these tests and collecting results using a Bash script. The approach allows for efficient, reusable testing across various platforms, including Kubernetes clusters, ensuring that web applications are thoroughly verified at each stage of their lifecycle before reaching end users.
