Build better, faster using TDD
Test-Driven Development (TDD) is a methodology that aims to improve software quality and development speed through a cycle of writing tests, implementing code to pass those tests, and then refactoring. Despite challenges such as steep learning curves and integrating TDD into existing projects, its benefits include increased code confidence, adaptability to changing requirements, improved usability, and preventing bugs from reappearing. Tips for effective TDD include writing fast tests, moving quickly from failing to passing tests, abstracting external dependencies, and combining unit and acceptance testing. TDD should be seen as a tool that complements the developer's workflow.

How to detect and prevent breaking changes in event schemas
There are several approaches to preventing breaking changes in event schemas, including consumer-driven contracts, using schema packages for integration tests, and utilizing a schema registry with broker-side validation. Each method offers unique benefits and potential drawbacks, and they may even be combined for optimal effectiveness. Consumer-driven contracts help enforce expectations at the development stage, sharing event schemas as code libraries simplifies setup, and a schema registry ensures centralized governance and protection against breaking changes.
