Add integration test with erratic. For this erratic now also returns an autopath searchpath. This tests the whole chain; i.e registring a searchfunction and calling that from autopath. This tests does a autopathing domain and a non-autopathing one.

# erratic
|
|
|
|
*erratic* is a middleware useful for testing client behavior. It returns a static response to all
|
|
queries, but the responses can be delayed, dropped or truncated.
|
|
|
|
The *erratic* middleware will respond to every A or AAAA query. For any other type it will return
|
|
a SERVFAIL response. The reply for A will return 192.0.2.53 (see RFC 5737), for AAAA it returns
|
|
2001:DB8::53 (see RFC 3849).
|
|
|
|
*erratic* can also be used in conjunction with the *autopath* middleware. This is mostly to aid in
|
|
testing.

## Examples

erratic {
|
|
drop 3
|
|
}

Or even shorter if the defaults suits you. Note this only drops queries, it does not delay them.
