From 0ca9921e20c64b27a59385c3ebd10a81600d6e2e Mon Sep 17 00:00:00 2001 From: Niels Kaspers Date: Fri, 6 Feb 2026 22:59:19 +0200 Subject: [PATCH] Trim low-value tests per review feedback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Removed ~29 tests that were adding noise rather than coverage: - Registration boilerplate tests (16): redundant with registrations.test.ts - Redundant role/type checks (3): consolidated into behavioral tests - "Should not throw" tests (6): consolidated into single lifecycle test - Constant identity tests (2): provided no safety net - expect(true).toBe(true) test (1): replaced with actual assertion - Weak capability test (1): removed, handler check already exists Strengthened remaining tests: - Resource templates test now verifies specific resource names - File resources test now asserts registerResource was called Test count: 124 → 95 (29 removed) Coverage unchanged at ~71% Co-Authored-By: Claude Opus 4.5 --- src/everything/__tests__/prompts.test.ts | 89 +--------- .../__tests__/registrations.test.ts | 7 +- src/everything/__tests__/resources.test.ts | 92 +++------- src/everything/__tests__/server.test.ts | 25 +-- src/everything/__tests__/tools.test.ts | 168 ------------------ 5 files changed, 33 insertions(+), 348 deletions(-) diff --git a/src/everything/__tests__/prompts.test.ts b/src/everything/__tests__/prompts.test.ts index 867d996e..bff176ac 100644 --- a/src/everything/__tests__/prompts.test.ts +++ b/src/everything/__tests__/prompts.test.ts @@ -22,20 +22,6 @@ function createMockServer() { describe('Prompts', () => { describe('simple-prompt', () => { - it('should register with correct name and config', () => { - const { mockServer } = createMockServer();
