I guessed you will return the string array with the IPs here instead of nil...

what do you mean with TestMain?

why are you using "dockertest" instead of "dockertest.v3"? has the dot no sense?

this resource is the Eureka container running, isn't it? a more descriptive name could be great 😄

👍 . I was following the examples to strictly 😸

what is Run from Testing doing?

See the previous reference about what TestMain actually does

mmmm, reaching this point I suspect that the m.Run() in TestMain does is to start the Eureka server to run the other tests after that. am I right?

Nops. TestMain does run Eureka (and kills it when tests finish), and in the middle, with m.Run , actually runs all your tests there. Its a mechanism allowing you to wrap all your tests and do things at the beginning and end (init only covers the first part, so that's why golang released this in... 1.5?)

"Addresses starting with "192.0.2.", "198.51.100.", or "203.0.113." are reserved for use in documentation and sample configurations. They should never be used in a live network configuration. No one has permission to use these addresses on the Internet."
I guess doing testing is no documentation...

Can you suggest another IP range which traffic will be dropped for sure? In fact, these networks are referenced as "TEST NETWORKs" in the RFC, so that was the best option I found...

you were right, don't change it.

why did you change from httpclient.Get to http.NewRequest + httpclient.Do?
There was a problem hiding this comment.
Because I'm trying to add a request header, and the Get method does not allow me so

WIP. Comparing the (old) public version in eureka with one that is newer, but not public...

I started to cover this:
#36
And following a tdd approach... tests are quite complete (but end to end), and main pending points are:
