Embodiment Construction

[0018]Prior to setting forth the detailed description, it may be helpful to set forth definitions of certain terms that will be used hereinafter.

[0019]The term “requirement” or “functional requirement” as used herein in this application refers to a requirement that defines a function of a software system or its component. A function is described as a set of inputs, the behavior, and outputs. Functional requirements may be calculations, technical details, data manipulation and processing and other specific functionality that define what a system is supposed to accomplish. Behavioral requirements describing all the cases where the system uses the functional requirements are captured in use cases. Functional requirements are supported by non-functional requirements (also known as quality requirements), which impose constraints on the design or implementation.

[0020]The term “design” as used herein in this application refers to a high level description, usually in computer system terms, ...

Abstract

A method that includes: running a set of functional tests over a computer code; determining, for each code element of the computer code, which functional test covered it, to yield a tests-elements coverage map; associating portions of the computer code with corresponding design portions or requirements derived from a design document or a requirements document respectively, associated with the computer code, to yield a design/requirements-code tracing map; deriving, from the tests-code coverage map and the design/requirements-code tracing map, a design/requirements-tests coverage map, exhibiting coverage of the computer code by the functional tests, in terms of the design or the requirements, wherein at least one of the running, the determining, the associating, and the deriving is executed by at least one processor.

Description

BACKGROUND[0001]1. Technical Field[0002]The present invention relates to computer code testing and more particularly, to determining design / requirements coverage of functional tests for a given computer code.[0003]2. Discussion of the Related Art[0004]Functional tests are used throughout the life cycle of computer code development in order to verify that the computer code being developed meets the functional requirements or the design according to which the computer code has been written. The functional requirements are usually set forth in a specification document, possibly written in a natural language by the client. A design is then written, also in a natural language by a computer system engineer. The design contains high level description, in computer system terms, detailing how to address the requirements.[0005]An important quantitative parameter in the code testing domain is the coverage of the design / requirements. The design / requirements coverage usually relates to the amoun...
