tdd-patterns

Common TDD anti-patterns include over-mocking, happy-path bias, and under-testing observable behavior. Identifying these anti-patterns during test design prevents brittle tests and improves software quality.

Apply universal TDD patterns across multiple tech stacks by enforcing the TDD loop and balanced assertions during planning and review. Stack-aware guidance adapts these universal rules to specific project environments.

Avoid over-mocking in AI-assisted systems by applying stack-aware TDD patterns that ensure observable behavior. These patterns guide test design to prevent happy-path bias and maintain balanced assertion quality.

Stack-aware test design works for reviewing existing test suites by applying universal patterns and anti-pattern guidance. It identifies limitations like over-mocking and under-testing observable behavior during the review phase.

Tests fail to verify observable behavior due to happy-path bias and under-testing. Applying stack-aware TDD patterns enforces observable behavior verification and balanced assertion quality to resolve these testing gaps.
