Go - Why test file automatically exclude from source?

Hi, I integrated sonarqube v.9.5 with golang 1.18, all was running as expected. but I got weird things. I don’t configure an sonar.exclusions but always got result exclusion unit test from source. My goal is, I want analyze unit test file to detect smell code and others rules from sonarqube. is that posisble?

result
