What missing coverage is this change adding exactly? The code coverage score is 100% for the library and it also has a mutation score of 100. Those number suggest there's no missing tests. |

@martincostello Thanks for the review! You’re right that coverage and mutation scores are already 100%. These tests aren’t to raise the percentage, but to lock in a few behavioral contracts: |

Moved the tests into RateLimiterResiliencePipelineBuilderExtensionsTests.cs as requested and removed the two standalone files. All TFMs pass locally (net9.0, net8.0, net481). Ready for another look. See PR #2711. @martincostello |
