tdd-workflow

To enforce a test-first workflow, define the expected request, response, and error scenarios in tests before writing any implementation code. This approach ensures your API endpoints are robust and well-tested from the very start by mandating test creation prior to development.

The recommended code coverage is a minimum of 80% across all test types, including unit, integration, and end-to-end tests. Enforcing this specific coverage threshold ensures high code quality and maintainability throughout the software development process.

To structure end-to-end tests using Playwright within a TDD workflow, first define user journeys and generate test cases. You then write the minimal implementation code required to pass those specific end-to-end tests, followed by refactoring and verifying coverage metrics.

Yes, you can use Jest for unit and integration tests. The TDD workflow specifies testing patterns for Jest to guide you through defining test cases, implementing code to pass tests, refactoring, and verifying that coverage metrics meet the required standards.

The steps to write tests before implementation code effectively involve defining user journeys, generating test cases, writing minimal code to pass those tests, refactoring the code, and finally verifying coverage metrics to ensure comprehensive testing across all layers.
