In this blog post by Gleb Bahmutov, the process of deploying a static site to GitLab Pages and conducting end-to-end browser tests using Cypress and GitLab CI is explored. The example project is a static site created from a Markdown file using VuePress, and the source code is accessible on GitLab. The post outlines the setup of utility scripts for local testing and the execution of lightweight smoke tests to ensure the site's functionality. It details the use of GitLab CI to automate testing and deployment, emphasizing caching strategies to optimize CI performance. The GitLab CI pipeline is designed with stages for testing, deploying, and conducting a confidence check on the deployed site, allowing for efficient validation and debugging through test artifacts and the Cypress Dashboard. The process ensures that every major transformation, such as building and deploying, does not introduce errors, with additional guidance on integrating Cypress with GitLab for enhanced testing capabilities.
