End-to-End Tests

This directory contains integration/E2E tests that test agent and server components together.

Running Tests

# Run all E2E tests
cd tests
go test -v ./...

# Run with no cache
go test -v -count=1 ./...

# Skip E2E tests (in other directories)
cd ../agent
go test -short ./...

Test Coverage

WebSocket Proxy Tests (`websocket_proxy_test.go`)

✅ TestWebSocketProxy_BasicFlow - Complete proxy request/response flow
✅ TestWebSocketProxy_UnreachableTarget - Error handling for unreachable targets
✅ TestWebSocketProxy_MultipleRequests - Concurrent proxy requests

HTTP API Tests (`http_api_test.go`)

✅ TestHTTPAPI_AgentRegistration - Agent registration endpoint
✅ TestHTTPAPI_Heartbeat - Agent heartbeat with authentication
✅ TestHTTPAPI_UnauthorizedAccess - Token validation
✅ TestHTTPAPI_DeviceUpload - Device batch upload endpoint

Test Organization

websocket_proxy_test.go - WebSocket proxy functionality tests
http_api_test.go - HTTP API endpoint tests
helpers_test.go - Shared test utilities

Test Structure

E2E tests use:

httptest.NewServer() to create mock HTTP servers
websocket.DefaultDialer to test WebSocket connections
t.Parallel() to run tests concurrently
testing.Short() to allow skipping with -short flag

Notes

Tests use ephemeral ports to avoid conflicts
Tests run in parallel where possible (~1.5s total execution)
Mock servers simulate agent and server behavior
Tests verify both success and error scenarios
