    Are Integrated Tests a Scam? TDD, Architecture, Fast Feedback – J. B. Rainsberger

    J. B. Rainsberger, TDD coach and software consultant, joins Marco to challenge common assumptions about software testing. They discuss why JB argues that “integrated tests are a scam,” how testing choices affect design and refactoring, and what teams get wrong when they rely too heavily on end-to-end tests. The conversation draws on decades of real-world experience working with development teams of all sizes. 💡 Topics in this episode: What “integrated tests” really are and why they cause problems Micro tests, fast feedback, and confidence-driven testing When deleting tests is the right decision How tests create pressure on system design Collaboration and contract tests explained Why there is no single testing best practice Practical advice for junior and senior developers New episodes every other Wednesday.
