Clean up tests logging (#1979)
* Clean up tests logging

This cleans up the travis logs so you can see the failures better.

Older tests in tests/ would call log.SetOutput(ioutil.Discard) in
a haphazard way. This add log.Discard and put an `init` function in each
package's dir (no way to do this globally). The cleanup in tests/ is
clear.

All plugins also got this init function to have some uniformity and kill
any (future) logging there in the tests as well.

There is a one-off in pkg/healthcheck because that does log.

chaos

Name

chaos - allows for responding to TXT queries in the CH class.

Description

This is useful for retrieving version or author information from the server by querying a TXT record for a special domainname in the CH class.

Syntax

chaos [VERSION] [AUTHORS...]
  • VERSION is the version to return. Defaults to CoreDNS-<version>, if not set.
  • AUTHORS is what authors to return. No default.

Note that you have to make sure that this plugin will get actual queries for the following zones: version.bind, version.server, authors.bind, hostname.bind and id.server.

Examples

Specify all the zones in full.

version.bind version.server authors.bind hostname.bind id.server {
    chaos CoreDNS-001 info@coredns.io
}

Or just default to .:

.  {
    chaos CoreDNS-001 info@coredns.io
}

And test with dig:

% dig @localhost CH TXT version.bind
...
;; ANSWER SECTION:
version.bind.		0	CH	TXT	"CoreDNS-001"
...
