I was experimenting with writing writing unit tests for MCP servers. I find unit testing incredibly useful for writing assertions for every MCP primitive: tools, prompts, and resources.
This helps with ensuring that future changes aren't breaking the server's behavior. To do this, I used a simple set up with Jest and MCPClientManager, a custom MCP client I wrote for testing.
