Codecov Introduces Bundle Analysis and Test Analytics to Optimize Coding

Codecov by Sentry, a dedicated code coverage reporting solution, announced Bundle Analysis and Test Analytics, two new solutions designed to accelerate workflows and arm developers with actionable insights to create a seamless development experience.

- Bundle Analysis: Bundle Analysis helps improve an application's performance, bandwidth usage, and load times by letting the developer know if what they're about to merge will cause any performance lapses. It also enables a developer to explore all of the modules in their JavaScript bundle and determine where they might be able to streamline the bundle size or find areas of concern. This makes it easier to spot performance issues before they hit production, so end users avoid load time frustrations and stay on the website.

- Test Analytics: Test Analytics, now in open Beta, is a new set of tools that identifies and flags to the developer exactly why a test failed within the Codecov Pull Request (PR) comment to spend less time debugging an issue. The updated Codecov PR comment tells a developer if their PR failure is from a test failure associated with the proposed code changes or the result of a systemic flaky test. Codecov also added Test Analytics into the Codecov UI providing developers with a simple summary of the tests in a project's test suite. This includes average duration, failure rate, commits failed, and the last time a test ran. Developers can gather insight into how tests impact CI performance and the developer experience.

"Developers don't have hours to spend debugging code or deciphering performance issues," said Eli Hooten, Director of Engineering for Codecov at Sentry. "We're excited to introduce our first solutions outside of code coverage and offer developers a complete solution to accelerate workflows and performance."

To use Bundle Analysis, users will need a bundler plugin setup with support for the current version of Rollup, Vite, or Webpack. Test Analytics is now available for all Codecov users in Open Beta.
