From 41c16270d2aeef93aed5d895da9221711f460f83 Mon Sep 17 00:00:00 2001 From: Ammar Date: Tue, 28 Oct 2025 18:50:02 +0000 Subject: [PATCH 1/7] =?UTF-8?q?=F0=9F=A4=96=20perf:=20optimize=20sendMessa?= =?UTF-8?q?ge=20integration=20tests=20(38%=20fewer=20API=20calls)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Restructured tests to reduce API calls and execution time while maintaining high confidence in the code. Changes: - Moved 12 provider-agnostic tests from describe.each to single-provider block - Removed redundant provider parity test (smoke tests already verify both) - Optimized token limit test: reduced from 40-80 messages to 10, single provider - Added DEFAULT_PROVIDER constant (Anthropic - faster and cheaper) Impact: - API calls: 45 → 28 (38% reduction) - Expected time savings: ~100 seconds (30-40% faster) - Expected runtime: 4-5 minutes (down from 6-7 minutes) Test coverage maintained: - Both providers: smoke test, API key errors, model errors, tool policy, system instructions, images - Single provider: IPC/streaming logic, reconnection, editing, tool calls, continuity, token limits _Generated with `cmux`_ --- tests/ipcMain/sendMessage.test.ts | 197 +++++++++--------------------- 1 file changed, 57 insertions(+), 140 deletions(-) diff --git a/tests/ipcMain/sendMessage.test.ts b/tests/ipcMain/sendMessage.test.ts index e318f9b12..6824ccd93 100644 --- a/tests/ipcMain/sendMessage.test.ts +++ b/tests/ipcMain/sendMessage.test.ts @@ -37,6 +37,10 @@ const PROVIDER_CONFIGS: Array<[string, string]> = [ ["anthropic", "claude-sonnet-4-5"], ]; +// Use Anthropic by default for provider-agnostic tests (faster and cheaper) +const DEFAULT_PROVIDER = "anthropic"; +const DEFAULT_MODEL = "claude-sonnet-4-5"; + // Integration test timeout guidelines: // - Individual tests should complete within 10 seconds when possible // - Use tight timeouts (5-10s) for event waiting to fail fast @@ -55,8 +59,9 @@ describeIntegration("IpcMain sendMessage integration tests", () => { const { loadTokenizerModules } = await import("../../src/utils/main/tokenizer"); await loadTokenizerModules(); }, 30000); // 30s timeout for tokenizer loading - // Run tests for each provider concurrently - describe.each(PROVIDER_CONFIGS)("%s:%s provider tests", (provider, model) => { + + // Smoke test - verify each provider works + describe.each(PROVIDER_CONFIGS)("%s:%s smoke test", (provider, model) => { test.concurrent( "should successfully send message and receive response", async () => { @@ -91,6 +96,12 @@ describeIntegration("IpcMain sendMessage integration tests", () => { }, 15000 ); + }); + + // Core functionality tests - using single provider (these test IPC/streaming, not provider-specific behavior) + describe("core functionality", () => { + const provider = DEFAULT_PROVIDER; + const model = DEFAULT_MODEL; test.concurrent( "should interrupt streaming with interruptStream()", @@ -269,11 +280,6 @@ describeIntegration("IpcMain sendMessage integration tests", () => { test.concurrent( "should handle reconnection during active stream", async () => { - // Only test with Anthropic (faster and more reliable for this test) - if (provider === "openai") { - return; - } - const { env, workspaceId, cleanup } = await setupWorkspace(provider); try { // Start a stream with tool call that takes a long time @@ -554,11 +560,7 @@ describeIntegration("IpcMain sendMessage integration tests", () => { expect(result.success).toBe(true); // Wait for stream to complete - const collector = await waitForStreamSuccess( - env.sentEvents, - workspaceId, - provider === "openai" ?
