Traditional continuous integration (CI) processes often create bottlenecks in development due to the sequential nature of build pipelines, which can result in delayed feedback and prolonged problem resolution. The SF JavaScript Meetup highlighted a solution involving Meteor 1.0 and Velocity, which aims to reduce end-to-end build times, including UI tests, to under 10 seconds, thus integrating testing more closely with the developer workflow and expediting issue resolution. End-to-end testing, while comprehensive, traditionally takes longer to execute as it tests the entire system as a black box, but the Testing Triangle suggests prioritizing unit tests to reduce build times. However, advancements in frameworks like Velocity are making it possible to perform end-to-end tests quickly, providing timely feedback during development rather than serving as an occasional safety net.
