TYPEDTESTSUITE

TYPEDTESTSUITE is a software testing concept describing a set of tests designed to be executed with multiple data types. The tests themselves are written in a type-parameterized way and are instantiated once for each type in a specified type list, enabling the same test logic to be reused across different type implementations.

Purpose and scope: TYPEDTESTSUITE aims to validate type-generic code, such as containers, algorithms, utilities, or API wrappers that must behave correctly for any allowed type. By writing tests once and applying them to a family of types, this approach helps detect type-specific edge cases and regressions.

Design and implementation: A type-parameterized test fixture is defined with a type parameter. Individual tests reference the parameter rather than a concrete type. The test framework then creates concrete test cases by substituting each target type. Some frameworks provide language features or macros to declare the type list; others rely on generics or reflection.

Usage: In practice, you specify a set of types (for example, int, float, or a custom numeric type) and register the test suite. The test runner executes the instantiated tests for all types. This approach reduces duplication and improves coverage, though it can increase compile times and test execution time.

Relation to existing concepts: TYPEDTESTSUITE is conceptually aligned with type-parameterized or typed tests found in several unit-test frameworks. Notably, Google Test provides similar capabilities through its typed-test and typed-test-suite features, illustrating how the concept is implemented in real-world tooling.
