## TL;DR

JUnit XML reports give code agents structured test failure evidence: suite, test case, file, duration, failure text, and sometimes attachments.

## Core Explanation

Raw CI logs are noisy, while test report artifacts preserve machine-readable failure context. A code agent can use JUnit-style reports to identify which test failed, compare failures across branches, and avoid editing unrelated code based on a partial log snippet.

Agents should still verify the CI job exit code. A report artifact can expose failures without controlling whether the job passed or failed.
