Write Tests

$ARGUMENTS

Testing Strategy

1. Identify what to test: Read the source code to understand behavior
2. Choose test type:
   • Unit tests (Jest): Individual functions/classes — *.test.ts alongside source
   • E2E tests (Playwright): Full user flows — packages/frontend/src/tests/
   • Evaluation (LangSmith): AI agent quality — eval/langsmith/ directories
3. Write tests following project patterns:

Jest Test Template

import { describe, it, expect, jest, beforeEach } from "@jest/globals";

describe("FunctionName", () => {
  it("should handle normal input", () => {
    // Arrange → Act → Assert
  });

  it("should handle edge cases", () => {
    // Empty, null, boundary values
  });

  it("should handle errors", () => {
    // Error paths and exceptions
  });
});

4. Run tests to verify they pass:
   • pnpm test:agents — Agent tests
   • pnpm test:backend — Backend tests
   • pnpm test:common — Common package tests
   • pnpm test:frontend — E2E tests

Test Coverage Goals

• Utility functions: 90%+
• Agent nodes: 80%+
• API endpoints: 80%+
• Vue components: 70%+
