Introduction

This section GB/T 29831 with reference to GB/T 16260.2-2006 "Software engineering - Product quality - Part 2. External metrics" Specific Given the system and software functionality of the quality metrics and measurement formulas.

The method set forth in this section is not a complete set, is still exploring new methods not included. Functional testing of personnel from Select the appropriate method of this single part or a plurality of combinations of methods for measuring the functional quality of the system under test conditions; also repair Change or use other methods not covered in this section.

This section applies to a variety of software products and related computer systems with functional requirements, but not every indicator is applicable to all kinds of meter Computer software products and related systems.

The main users of this standard is expected to include.

a) the demand side (obtained from the supplier or procurement system, software product or software service individual or organization);

b) the evaluator (individual or organization to implement the evaluation);

c) the supplier (the contract provided by the system, organization or individual software product or software service to the acquirer), which is indeed the eligibility test when using recognized software quality.

GB/T 29831.1 "Systems and software features - Part 1. Indicator System" gives the functional index system, GB/T 29831.3 "system Systems and software functionality - Part 3. Test methods "describes the test method for functional indexes. This section is intended and GB/T 29831.1 and GB/T 29831.3 combination.

Systems and software functionality Part 2. Measurement Methods

1 Scope

This section GB/T 29831 on the basis of GB/T 29831.1 proposed index system, provides the functionality of the system and software the amount of formula to provide a unified functional measure of demand-side system and software evaluator for the party.

This section applies to functional testing and measurement of computer software products and related systems.

NOTE. The system referred to in this section are primarily software system.

4 Description of functional decomposition

Testing requirements for software functionality, the most important is to determine the software features. From different sides may have to distinguish between software functions in different ways, this section is not specified, but is given in Appendix A general method for setting the software functions. Refer to Appendix A functional decomposition of Select the method or other suitable method.

Completeness 5

Completeness is a measure of software requirements specification fully functional capacity, including full features, functions implemented End Integrity, functions to achieve coverage and other indicators, as shown in Table 1.

Table 1 Completeness

Index Name Index Description Measure, formula and data element computations measurements Description Full sexual function They are evaluated fully functional degree X = 1-A/B where.

A --- detected number does not meet the functional requirements;

B --- Total requirements specification described functionality Note. The general method is recommended to use functional decomposition, see Appendix A.
