How to Test the Complete MCP Workflow
OgnjenAdzic · reddit · 2026-07-16
The author points out that while many MCP tests only verify if a single tool returns the correct result, the real difficulty lies in validating the entire task chain. They give an example where an agent might make perfectly valid tool calls at every step, yet still: - Select the wrong customer. - Incorrectly retry a write operation after a timeout. - Claim the task is complete without checking the final state. Therefore, they are asking the community if mature end-to-end testing methods exist: Should we run scenarios across different agents/clients, or should we independently verify the application's final state beyond just checking traces and tool responses?
