Quality as a Continuous Process

Many developers view testing as a final step before deployment. At Nodezee, we view it as the Design Phase. By utilizing Test-Driven Development (TDD), we ensure that every line of code written has a purpose and a proof of success. In our 150+ deployed systems, projects with high test coverage have 70% fewer production incidents.

1. The Testing Pyramid

Our strategy follows the classic pyramid: Thousands of fast Unit Tests (using Jest), hundreds of Integration Tests (checking database interactions), and a core set of End-to-End (E2E) Tests (using Playwright). This balance gives us maximum confidence with minimum build time.

2. Mocking External Dependencies

A test that relies on a live API is a "Flaky Test." We use tools like Nock or MSW to mock external network requests, ensuring our CI/CD pipeline can run in complete isolation. This allows our 30+ engineers to push code 10 times a day with the certainty that they haven't broken existing functionality.

3. The 90% Coverage Target

While "100% coverage" is often a vanity metric, we aim for 90% logic coverage. This doesn't mean testing every getter and setter; it means testing every possible failure state of our business use cases. When you hire Nodezee, you aren't just getting code; you are getting a verified, self-documenting system that can be safely updated for years to come.
