Thanks for opening a backport.

Before merging, please confirm that it falls into one of the following categories (select one):

• Non-production code changes. Includes test-only changes, build system changes, etc.
• Fixes for serious issues. Defined in the policy as correctness, stability, or security issues, data corruption/loss, significant performance regressions, breaking working and widely used functionality, or an inability to detect and debug production issues.
• Other approved changes. These changes must be gated behind a disabled-by-default feature flag unless there is a strong justification not to.

Add a brief release justification to the PR description explaining your selection.

Also, confirm that the change does not break backward compatibility and complies with all aspects of the backport policy.

All backports must be reviewed by the TL and EM for the owning area.

✅ PR #157092 is compliant with backport policy

Confidence: high
Backward compatible: true
Explanation: The PR falls under the non-production exemption, as it modifies code within the 'pkg/cmd/roachtest/' directory, which is explicitly mentioned in the policy for CockroachDB backport compliance as a development tools area. Since this PR changes a testing file and the PR's body includes a 'Release justification: test only change' line, it is exempt from the standard backport policy requirements.
