Table-driven unit tests in Go are structured by defining test cases in a slice of structs, iterating over them, and executing assertions to standardize verification of domain models. This approach ensures uniform coverage of invariants across the repository.

A unit test is needed when verifying isolated business logic with low domain complexity and few collaborators. Integration tests are reserved for higher complexity scenarios, ensuring tests remain fast and deterministic based on collaborator count.

Classical mocking philosophy in Go unit testing utilizes fakes or mocks to handle dependencies, ensuring tests remain isolated and behavior-coupled. This approach prioritizes maintainability and resistance to refactoring over strict interaction verification.

Flakiness in Go unit test suites is prevented by enforcing a behavior-driven standard that isolates business logic using fakes or mocks. This ensures fast, deterministic verification of domain models without external dependencies.

TDD-gate enforcement works effectively with table-driven Go tests by coupling assertions to behavior and using classical mocking. This combination satisfies TDD requirements while ensuring test suites remain maintainable and resistant to refactoring.
