Software Testing - ISO Standards


Advertisements


Many organizations around the globe develop and implement different standards to improve the quality needs of their software. This chapter briefly describes some of the widely used standards related to Quality Assurance and Testing.

ISO/IEC 9126

This standard deals with the following aspects to determine the quality of a software application −

  • Quality model
  • External metrics
  • Internal metrics
  • Quality in use metrics

This standard presents some set of quality attributes for any software such as −

  • Functionality
  • Reliability
  • Usability
  • Efficiency
  • Maintainability
  • Portability

The above-mentioned quality attributes are further divided into sub-factors, which you can study when you study the standard in detail.

ISO/IEC 9241-11

Part 11 of this standard deals with the extent to which a product can be used by specified users to achieve specified goals with Effectiveness, Efficiency and Satisfaction in a specified context of use.

This standard proposed a framework that describes the usability components and the relationship between them. In this standard, the usability is considered in terms of user performance and satisfaction. According to ISO 9241-11, usability depends on context of use and the level of usability will change as the context changes.

ISO/IEC 25000:2005

ISO/IEC 25000:2005 is commonly known as the standard that provides the guidelines for Software Quality Requirements and Evaluation (SQuaRE). This standard helps in organizing and enhancing the process related to software quality requirements and their evaluations. In reality, ISO-25000 replaces the two old ISO standards, i.e. ISO-9126 and ISO-14598.

SQuaRE is divided into sub-parts such as −

  • ISO 2500n − Quality Management Division
  • ISO 2501n − Quality Model Division
  • ISO 2502n − Quality Measurement Division
  • ISO 2503n − Quality Requirements Division
  • ISO 2504n − Quality Evaluation Division

The main contents of SQuaRE are −

  • Terms and definitions
  • Reference Models
  • General guide
  • Individual division guides
  • Standard related to Requirement Engineering (i.e. specification, planning, measurement and evaluation process)

ISO/IEC 12119

This standard deals with software packages delivered to the client. It does not focus or deal with the clients’ production process. The main contents are related to the following items −

  • Set of requirements for software packages.
  • Instructions for testing a delivered software package against the specified requirements.
