描述

Use case: I have am writing an implementation of IETF http message signatures. The spec has a lot of examples of signed HTTP messages signed with a validity period. To test the library I would like to set the Clock to a specific valid time and to invalid times, to check that the implementation is correct, i.e. that it fails a correct signature when the date is no longer valid.

I have spent at a few hours looking through the isses that led to the test runtime including the very nice documentation, looked at the source code, issues that led to it. But I could not find out how to do that... I may be missing something obvious...

研究方向
The issue requests a way to set the Clock in cats effect TestKit for testing time sensitive logic like HTTP message signatures. The relevant source code is in the testkit module, specifically the TestContext class, which provides the test runtime. Researchers should examine the TestContext source to see if a setClock method exists or needs to be added. The issue body links to the test runtime documentation and a related PR. Checking the issue comments for maintainer feedback on feasibility and implementation details is recommended.
