Implementation Reference

• src/tools/cognitive.ts:529-594 (handler)

  The handler function for the 'generate_tests' tool. It takes feature and type arguments, generates a markdown template with suggested test cases for unit, integration, and E2E tests based on the type, and returns it as text content.

  export function generateTestsHandler(args: any) {
      const { feature, type = "all" } = args;
  
      const tests = `# Test Cases: ${feature}
  
  ## Test Type: ${type}
  
  ---
  
  ## Unit Tests
  ${type === "unit" || type === "all" ? `
  ### Happy Path
  - [ ] Test with valid input
  - [ ] Test with typical use case
  - [ ] Test expected output format
  
  ### Edge Cases
  - [ ] Test with empty input
  - [ ] Test with null/undefined
  - [ ] Test with boundary values
  - [ ] Test with maximum values
  
  ### Error Handling
  - [ ] Test with invalid input
  - [ ] Test error messages
  - [ ] Test error recovery
  ` : "Not requested"}
  
  ## Integration Tests
  ${type === "integration" || type === "all" ? `
  ### Component Integration
  - [ ] Test with real dependencies
  - [ ] Test database interactions
  - [ ] Test API calls
  
  ### Data Flow
  - [ ] Test data transformation
  - [ ] Test state management
  - [ ] Test event handling
  ` : "Not requested"}
  
  ## E2E Tests
  ${type === "e2e" || type === "all" ? `
  ### User Flows
  - [ ] Test complete user journey
  - [ ] Test critical paths
  - [ ] Test error scenarios
  
  ### Cross-browser/Device
  - [ ] Test on multiple browsers
  - [ ] Test responsive behavior
  ` : "Not requested"}
  
  ## Test Data
  - Prepare mock data
  - Create test fixtures
  - Set up test database
  
  ## Coverage Goals
  - Aim for > 80% coverage
  - Cover all public APIs
  - Include edge cases

• src/tools/cognitive.ts:520-527 (schema)

  Zod schema definition for the 'generate_tests' tool, specifying input parameters: feature (required string) and type (optional enum: unit, integration, e2e, all).

  export const generateTestsSchema = {
      name: "generate_tests",
      description: "Generates test case suggestions for a feature or function.",
      inputSchema: z.object({
          feature: z.string().describe("The feature or function to test"),
          type: z.enum(["unit", "integration", "e2e", "all"]).optional().describe("Type of tests")
      })
  };

  ["generate_tests", { schema: generateTestsSchema, handler: generateTestsHandler }],

• src/server.ts:96-96 (registration)

  Registration of the 'generate_tests' tool in the toolRegistry Map used by the HTTP MCP server.
