sdtest was a client simulation tool for testing DNS subscriptions. It was written in C and while useful, was limited by the amount of code required to extend it and the lack of C programmers who would do so.
Therefore, the project was terminated in favor of a new extensible tool called nst (Name Server Test tool) written in javascript node.js. See more on this site under test for more information on nst.
nst is a new tool written in javascript node.js. It is a generic DNS name server test tool that can be used to test new DNS features in a server.
A major goal is to be able to support testing of long-lived DNS connections in addition to simple query/response tests. Long-lived connections are used for DNS Privacy connection optimization, DNS Stateful Operations such as DNS Push Notifications, and service discovery with a discovery proxy and relay.
sdtest is a client simulation tool for testing DNS subscriptions. It supports both the older Long Lived Queries (LLQ) and the new replacement DNS Push Notifications.
Since it is a work in progress, the best way to follow it is to look at the github sdtest project documentation that is being updated as the code is written.
