Non-Func. Testing

Non-Functional Testing


A meeting of the BCS Specialist Interest Group on Software Testing was held in September 1998.  This meeting agreed that existing testing standards did not cover the area of the testing of non-functional attributes of software systems.  The SIGIST formed a working party to develop this standard, which addresses the quality of testing in this area. 

This standard contains formal definitions and guidelines of techniques for testing the non-functional attributes of software systems, as well as examples of their use.  It enables users to improve the quality of their software testing and thus the quality of their software products.

Examples of the application of the definitions can be accessed directly via the domain-technique matrix.

Different non-functional testing techniques are applicable for different levels of testing.  The relationship between techniques and testing phases is shown in the applicability through the SDLC matrix.

The standard can be used in the context of both the “Inspections and testing” provisions of BS EN ISO 9001 and the “Software coding and testing” provisions of BS ISO/IEC 12207.


The objective of this Standard is to enable the measurement and comparison of the testing of non-functional attributes of software systems.  This will enable users of this Standard to directly improve the quality of their software testing, and improve the quality of their software products.

 Intended audience

The target audience for this Standard includes:

bullettesters and software developers;
bulletmanagers of testers and software developers;
bulletprocurers of software products or products containing software;
bullettechnical support staff;
bulletquality assurance managers and personnel;
bulletacademic researchers, lecturers, and students;
bulletdevelopers of related standards.
