Testability

Testability is the ease with which code can be tested. This section covers test isolation, deterministic tests, test data management, and contract-driven testing.

What you'll find here

• Test Isolation and Determinism — Isolate units; avoid flaky tests.
• Test Data Management — Fixture factories, synthetic data, data masking.
• Contract and Consumer-Driven Tests — CDC, contract testing, pact.

📄️ Test Isolation and Determinism

Write tests that are independent, repeatable, and not flaky.

📄️ Test Data Management

Manage test data effectively using fixtures, factories, and synthetic data.

📄️ Contract and Consumer-Driven Tests

Test API contracts between services; catch breaking changes early with CDC.
