I tried unit tests on the master branch and many tests were broken. I suspect it's caused by dependency issues? I used "dep ensure" to download dependencies. It's much appreciated If you have some pointers on how to solve the local unit test failures.

go test ./... output: https://raw.githubusercontent.com/caesarxuchao/go/test/testlog

@caesarxuchao I faced the similar issue in running tests. I used the following command to fetch test dependencies, and it worked go get -t ./...

[caesarxuchao]

Thanks @sai-g. I also installed the json-iter/go at the wrong path. After moving it to $GOPATH/github.com/json-iterator/go, and run go get -t ./..., I'm able to pass the test locally.

Does this code above also make decoding case-insensitive?

for k, binding := range bindings {
  if _, found := fields[strings.ToLower(k)]; !found {
    fields[strings.ToLower(k)] = binding.Decoder.(*structFieldDecoder)
  }
}

A test case that exercises positive and negative cases would be good

Yes, this was the culprit.
