Sauce Labs is expanding its developer-first test capabilities with the introduction of `saucectl`, a native JavaScript solution that combines Puppeteer and Jest. The tool aims to provide a magical test experience for developers, making it easy to set up, write, run, and debug web tests. With `saucectl`, users can execute tests from their laptops and report data to the Sauce Labs public cloud for further analysis. The tool is designed to be lightweight, open-source, and adaptable, with support for multiple browsers and automation frameworks. Sauce Labs believes in contributing to open-source software (OSS) and maintaining a strong connection to critical standards bodies. The solution aims to simplify testing and provide developers with the benefits of community support and improvement.
