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.

For years, infrastructure teams have treated compute as a relatively stable input. Capacity was provisioned, costs were forecasted, and performance expectations were set based on the assumption that identical resources behaved identically. That mental model is starting to break down. AI infrastructure is no longer behaving like static cloud capacity. It is increasingly behaving like a market ...

Resilience can no longer be defined by how quickly an organization recovers from an incident or disruption. The effectiveness of any resilience strategy is dependent on its ability to anticipate change, operate under continuous stress, and adapt confidently amid uncertainty ...

Mobile users are less tolerant of app instability than ever before. According to a new report from Luciq, No Margin for Error: What Mobile Users Expect and What Mobile Leaders Must Deliver in 2026, even minor performance issues now result in immediate abandonment, lost purchases, and long-term brand impact ...

Agentic AI is a major buzzword for 2026. Many tech companies are making bold promises about this technology, but many aren't grounded in reality, at least not yet. This coming year will likely be shaped by reality checks for IT teams, and progress will only come from a focus on strong foundations and disciplined execution ...

AI systems are still prone to hallucinations and misjudgments ... To build the trust needed for adoption, AI must be paired with human-in-the-loop (HITL) oversight, or checkpoints where humans verify, guide, and decide what actions are taken. The balance between autonomy and accountability is what will allow AI to deliver on its promise without sacrificing human trust ...

Enterprise IT has become increasingly complex and fragmented. Organizations are juggling dozens — sometimes hundreds — of different tools for endpoint management, security, app delivery, and employee experience.
