Test suite fails if there is no network access

[peti]

In NixOS, we run all builds (and their test suites) in a protected environment which restricts what those packages can do. For example, builds do not have network access. This means that the current version of dns can no longer pass its test suite: http://hydra.cryp.to:8080/build/6557/nixlog/2/raw.

Is there any way to run the test suite in such a way that those parts that require network access are disabled?

It's hard but possible.

You should prepare a mock DNS server and customize dns with RCHostName to look up the local mock DNS server.

Wouldn't it be much easier to split the test suite in two parts: one that requires network access and one that doesn't?

[kazu-yamamoto]

It's a piece of cake. I created a new branch "test2". Please look. For non-network test, type "cabal test spec".

[peti]

Very nice. Would it be possible to get that updated version via Hackage?

[kazu-yamamoto]

Done!

I've re-enabled the test suite in NixOS in commit 884a8fc7. Thank you for your help!
