Description

Description:

#176 introduces an xdstest command, which instantiates an xDS server to perform manual testing against. This issue covers work to turn this into an automated test that can be run by CI or locally.

The largest part of this work is that it will require an xDS client test library that supports:

  • connecting to an xDS server
  • accepting updates
  • Comparing the updates to an expected outcome

Because this process is asynchronous and requires multiple goroutines working together to work, there's a bit of design work to ensure that the testing framework isn't its own source of bugs.

Contributor guide

Research direction
Start by examining the existing xdstest command implementation from PR #176. Understand how the xDS server is instantiated and how manual testing is done. Then, design an automated test framework that can connect to the xDS server, accept updates asynchronously, and compare them to expected outcomes. Look for existing test patterns in the repository for inspiration.
