Anyone can help with a solution?

Notes:

1. I dont want to change my test to use sudo in the code, because later when it is used the user should decide by himself whether to use sudo or not

The first is to update the current working directory permission, with chmod 777 . (yes I set all, dont want to really bother with travis specific behavior), but turns out it doesn't work. Don't know for sure the cause this time, probably the dynamically generated binary also have permission issue

The solution that works for me is reading the go binary path, then re-run it as sudo, as shown below

script: 
  - GO_EXECUTABLE_PATH=$(which go)
  - echo $GO_EXECUTABLE_PATH
  - sudo $GO_EXECUTABLE_PATH test ./...
