Table-driven tests reduce duplication in Go unit tests by consolidating multiple inputs and edge cases into a single data structure looped through a test harness, ensuring consistent coverage and improved maintainability across your codebase.

Slice-pattern tests in Go enforce deterministic case ordering by iterating through a slice of structs, while map-pattern tests allow non-deterministic execution orders, both supported by table-driven testing to structure repetitive case checks effectively.

Table-driven tests integrate with t.Run subtests in Go by looping through a cases table and passing each case's name to t.Run, creating isolated, readable subtest outputs that align with standard Go testing practices and repository conventions.

Refactor Go tests into a table-driven pattern when testing functions with multiple inputs, varying behaviors, or numerous edge cases, consolidating repetitive case checks to improve test readability, maintainability, and consistent coverage across the codebase.

Table-driven testing aligns with standard Go repository conventions for naming and structure, supporting both slice-pattern and map-pattern styles to ensure consistent test coverage and maintainability without conflicting with existing project practices.
