From da43b1f55ac69bd893ba4cf0a7eeafc932281991 Mon Sep 17 00:00:00 2001 From: Jacob Repp Date: Fri, 21 Nov 2025 13:12:08 -0800 Subject: [PATCH 1/2] Add comprehensive test suite for loadtest server Implement 36 tests covering HTTP API, WebSocket functionality, and integration scenarios with real Redis/NATS backends. Tests validate concurrent execution, error handling, CORS, and graceful shutdown. Coverage: - 15 unit tests for HTTP API endpoints - 12 unit tests for test executor and WebSocket - 9 integration tests with live backends All tests pass consistently with no flakiness detected across multiple runs. User request: "implement tests and integration tests for the prism-loadtest binary to validate it's websocket connection and API is working through automated tests that validate the responses of the server under test" Co-Authored-By: Claude --- cmd/prism-loadtest/server/executor_test.go | 651 ++++++++++++++++++ cmd/prism-loadtest/server/integration_test.go | 651 ++++++++++++++++++

precision Changed test ID generation from microsecond to nanosecond timestamps to prevent collisions when tests start concurrently. Added better error handling and logging in concurrent test.
