Integration Testing Skill

Dynamic path: All paths below use components/<testing-component>/ as a placeholder. The actual directory depends on the testing component defined in sdd/sdd-settings.yaml. Delegate to the techpack-settings skill for directory path resolution — it maps component type (testing) + name to a filesystem path (e.g., type=testing, name=integration → components/testing-integration/).

Tests that verify multiple components working together with real infrastructure. Integration tests run in Kubernetes via Testkube for environment parity.

Resource Files

For detailed guidance, read these on-demand:

• database-strategies.md — Transaction rollback, truncate, cleanup
• api-testing.md — HTTP client, test patterns, examples
• authentication.md — Login helpers, protected endpoint tests
• testkube.md — Test definition YAML, suites, running tests

Contract Testing

Request/Response Validation

import { describe, it, expect } from 'vitest';
import Ajv2020 from 'ajv/dist/2020.js';
import openApiSpec from '../../../../contract/openapi.json';

const ajv = new Ajv2020({ allErrors: true });

describe('API Contract Compliance', () => {
  describe('POST /api/users', () => {
    it('response matches OpenAPI schema', async () => {
      const response = await client.post('/api/users', validUserData);

      const schema = openApiSpec.paths['/api/users'].post.responses['201'].content['application/json'].schema;
      const validate = ajv.compile(schema);
      const valid = validate(response.data);

      expect(valid).toBe(true);
      if (!valid) {
        console.error('Schema validation errors:', validate.errors);
      }
    });
  });
});

Rules

• Real infrastructure - Use actual database, no mocks for I/O
• Environment parity - Tests run in Kubernetes like production
• Cleanup after each test - Leave database in clean state
• Independent tests - Tests must not depend on each other
• Idempotent tests - Running twice produces same result
• Reference spec and issue - Use @spec and @issue JSDoc tags
• Given/When/Then structure - Clear test organization
• Handle async properly - Await all database and HTTP operations
• Reasonable timeouts - Set appropriate timeouts for network operations

---

Summary Checklist

Before committing integration tests, verify:

• Tests use real database (not mocked)
• Database cleanup happens after each test
• @spec and @issue tags present in file header
• Each acceptance criterion has corresponding tests
• Tests follow Given/When/Then structure
• HTTP client properly configured for test environment
• Authentication helpers used for protected endpoints
• Error scenarios tested (400, 401, 403, 404, 409, 500)
• Testkube YAML definition created/updated
• Tests run successfully via testkube run test
