COMPLIANCE TESTING, also known as conformance testing, regulation testing, standards testing, is a type of testing to determine the compliance of a system with internal or external standards.
Internal standards could be standards set by the company itself. For example, a web application development company might set the standard that all webpages must be responsive.
External standards could be standards set outside of the company. For example, Health Insurance Portability and Accountability Act (HIPAA) has set regulations for the healthcare industry.
Compliance testing could also be done by an external organization. This normally results in some sort of compliance certification.
The method and type of testing to be conducted during compliance testing depends on the specific regulation / standard being assessed.
The depth of compliance testing could range from a high-level audit on a sampling basis to a detailed scrutiny of each specified standard.
