ConformanceTestSuites

ConformanceTestSuites are organized collections of tests designed to determine whether a software implementation, device, or system conforms to a defined specification, standard, or protocol. They aim to ensure interoperability, correctness, and predictable behavior across different implementations by exercising required features, optional features, boundary conditions, and error handling paths.

A typical ConformanceTestSuite includes positive tests that verify expected behavior, negative tests that verify proper handling of invalid inputs, interoperability scenarios, and performance or timing checks when relevant. Tests are often accompanied by formal test specifications, expected outcomes, and automation harnesses that run tests, collect logs, and report results. Suites may be developed by standards bodies, vendor consortia, or open-source communities, and are frequently used in certification programs or compliance labeling.

Designing and maintaining a ConformanceTestSuite involves selecting coverage criteria, writing reproducible test cases, versioning suites alongside the standard, and addressing ambiguities in the specification revealed by test failures. Automation and continuous integration are commonly used to run suites against reference implementations and regressions. Limitations include incomplete coverage, possible false positives/negatives, and the effort required to update tests for evolving standards. Because no suite can exhaustively prove correctness, conformance testing is typically combined with other quality assurance practices such as formal verification, fuzz testing, and interoperability events to increase confidence in implementations.
