I have a error in ci

can using goconvey to write tests？ @creasty

Thank you for suggesting a testing library along the way.
However, it's better to keep the focus of PR on one thing at a time and we should discuss it separately.

Personally, I've always wanted to introduce https://github.com/stretchr/testify which I'm familiar with and is seemingly the most popular choice.

As for the error, golangci/golangci-lint#1920 might be the case.
