From 063239fa37036de194b2d30b94f91c8701a603ca Mon Sep 17 00:00:00 2001 From: Matthieu MOREL Date: Sat, 21 Sep 2024 17:04:28 +0200 Subject: [PATCH] [chore]: enable len and empty rules from testifylint (#5832) #### Description Testifylint is a linter that provides best practices with the use of testify. This PR enables [empty](https://github.com/Antonboom/testifylint?tab=readme-ov-file#empty) and [len](https://github.com/Antonboom/testifylint?tab=readme-ov-file#len) rules from [testifylint](https://github.com/Antonboom/testifylint) Signed-off-by: Matthieu MOREL --- .golangci.yml | 2 -
