To refactor a brittle test suite, audit existing tests against anti-patterns like testing internal implementation details, then systematically merge, refactor, or delete low-value tests while maintaining coverage through public interfaces.

Common test suite anti-patterns include testing internal implementation details rather than public behavior, and maintaining redundant happy-path scenarios, both of which cause noisy, bloated, and fragile test suites.

Clean up implementation-focused tests by applying a structured refactoring workflow that shifts verification to public interfaces, ensuring tests validate what the code does rather than how it works internally.

Yes, you can audit your test suite by invoking an automated review process that evaluates test files against established anti-patterns, generating a summary report of recommended changes to remove redundant scenarios.

The best way to maintain coverage when deleting low-value unit tests is to enforce public-interface testing, ensuring that behavioral verification is shifted from internal mechanics to outward-facing code contracts.

Avoid a test suite refactoring workflow if your project lacks established public interfaces or requires strict verification of internal implementation details, as the process focuses on behavioral verification and public-facing contracts.
