@closetool can you work on this?

[kilosonc]

ok, I'll try to fix it

[kilosonc]

I guess the go version in travis.yml should be 1.14.x at least

and the coveralls service should be opened

[hsluoyz]

@closetool coveralls is enabled: https://coveralls.io/github/casbin/caddy-authz?branch=master

[kilosonc]

@hsluoyz yes, but some packages require go version over 1.14 like github.com/caddyserver/certmagic

[hsluoyz]

@closetool good to know!

Please make a PR to fix the Go versions here: https://github.com/casbin/caddy-authz/blob/master/.travis.yml#L6

We usually test against several popular Go versions including tip. Please refer to Go Casbin repo for it.

@closetool good to see CI recovered! But I saw the code coverage has dropped to 0%, can you investigate why?

https://coveralls.io/github/casbin/caddy-authz?branch=master

[kilosonc]

sure

[kilosonc]

@hsluoyz I compared v2.0.0 and v1.0.2, and I found there's no authz_test.go in v2.0.0
perhaps that's why coverage dropped to 0%

[hsluoyz]

good found! I think this PR: https://github.com/casbin/caddy-authz/pull/7/files deleted authz_test.go. We need to add it back and make it right in the new Caddy v2 scenario, as our code needs testing to make it behave as expected.

[kilosonc]

ok, I'll work on it
