Use meaningful smoke tests

In the blog post, Gleb Bahmutov discusses the importance of using meaningful smoke tests alongside comprehensive end-to-end (E2E) and unit tests to ensure a robust user experience for web applications. Despite achieving 100% code coverage with tools like Cypress, Bahmutov argues that this alone does not guarantee a flawless user experience across different browsers. He suggests focusing on running all tests in one browser and conducting smoke tests in others, such as Firefox, to quickly identify major issues that could disrupt the user experience. Using the TodoMVC application as an example, he demonstrates how a single smoke test can verify key features like adding, completing, and viewing tasks, achieving substantial code coverage. Bahmutov emphasizes the utility of smoke tests in assessing application functionality across various screen resolutions and browsers, thereby ensuring a smooth deployment process. The approach streamlines testing efforts while maintaining high-quality user experiences across platforms.
