Ferran contributed to the checkly/checkly-cli repository by building and enhancing CLI tooling for Playwright test automation, focusing on robust configuration management and developer experience. Over ten months, Ferran delivered features such as real-time log streaming, flexible install commands, and dynamic Playwright configuration paths, using TypeScript, Node.js, and JavaScript. The work included implementing utilities for shell quoting, improving dependency analysis, and integrating CI/CD workflows with GitHub Actions. By addressing error handling, test reliability, and cross-package-manager support, Ferran’s engineering enabled safer, more flexible test authoring and execution, resulting in a more resilient and maintainable CLI for diverse development environments.
February 2026: Delivered a Flexible Playwright Test Install Command in checkly-cli, enabling users to specify a custom install command for pw-test and thus improving dependency management and CI pipeline flexibility. Implemented the --install-command flag, added tests for the flag, and performed test suite fixes to stabilize the feature rollout. Business value includes smoother CI integration, reduced maintenance burden for diverse environments, and faster test runs.

August 2025 — Focused on delivering real-time test log streaming in the Checkly CLI and strengthening test-runner reliability. Delivered Real-time Test Log Streaming by adding a --stream-logs flag to pw-test and integrating streaming into the test runner and reporters for live debugging and monitoring. The work included cross-package-manager support for pw-test and refactoring of shared logic into helpers, plus establishing a base pw-test command to ease future feature work. Implemented targeted bug fixes to streaming output (timestamp parsing, array property validation) and cleaned up code (removing unused imports) to improve stability. These changes delivered measurable business value by enabling faster debugging, clearer test outputs, and more resilient CI workflows.
