Integration tests for MCP tools validate tools, resources, and prompts by simulating external API responses and asserting correct execution. This Skill provides patterns to structure these tests for reliable protocol interactions.

Mocking APIs when testing MCP resources involves simulating external responses to ensure reliable and deterministic tests. This Skill offers patterns to stub network requests and validate tool inputs and outputs without live dependencies.

Vitest works for testing Model Context Protocol error handling by allowing you to define test cases that trigger exceptions and validate error responses. This Skill provides scenarios to ensure robust error handling coverage.

Validating data schemas in MCP integration tests ensures that inputs and outputs conform to expected structures. This Skill provides best practices for schema validation to catch data format errors during tool execution.

MCP testing may not reach 80% code coverage if error handling scenarios and edge cases are untested. This Skill provides patterns to identify gaps and write comprehensive tests targeting uncovered execution paths.

You can test MCP prompts using unit testing patterns by isolating prompt execution and validating outputs against expected schema structures. This Skill outlines methods to achieve high code coverage for prompt logic.
