Cable: An Internal Continuous Integration Platform for Efficient Release and Quality Assurance at Qunar

Background In a fast‑moving internet product environment, short development cycles and frequent releases lead to wasted time caused by code issues, inconsistent environments, low test quality, and frequent rollbacks, prompting the adoption of continuous integration (CI) to improve efficiency and quality.

Solution Overview Qunar designed the Cable platform based on CI best practices, offering a suite of automated checks and a unified workflow to catch problems early and reduce manual effort.

Diverse Checks Cable supports two main categories of checks: (1) static code analysis, including code review, Sonar, and unit tests; (2) environment‑related service verification, such as automated testing and MySQL slow‑query detection. Additional tools can be integrated to broaden coverage.

Convenient Configuration Users can configure rules per Git repository or Git group, defining three metrics for each check: pass criteria, impact of failure, and trigger timing. Checks like Sonar, unit tests, and code review are triggered automatically on push, while slow‑query and automated tests run on scheduled polls.

Rapid Feedback Integration with Qunar's data center (IC) enables real‑time notifications via QTalk or email, providing immediate and precise feedback to developers and preventing issues from propagating downstream.

Friendly Display Results are presented in multiple dimensions tailored to different user scenarios, allowing views by organization, individual, or project, and supporting visual dashboards for quick insight.

Future Plans The roadmap includes extending check methods (adding more automated checks), accelerating check execution (optimizing resources, parallelism, and selective re‑runs), and simplifying configuration (self‑service environment creation using Docker and integration with internal tools like Noah).

Summary The platform is named Cable, symbolizing a smooth connection across the development lifecycle and drawing inspiration from the Marvel character “Cable” to link past imperfections with a better future.
