Abstract

In the program for generating a test case based on a use case diagram and the method for generating a test case using the same according to exemplary embodiments of the present invention, since a use case specification specifying a procedure or method scenario performed in a use case diagram is used to complement insufficient information of a use case diagram used to extract a test case, a layer, although he is not a specialist or an expert, can easily generate a certain level of a test case to effectively perform a test. Thus, requirements can be verified in advance by generating a test case from a use case program, reducing the costs for a system development.

Dependent claims

A non-transitory computer readable medium storing a program that, when executed by a computer, causes the computer to generate a test case based on a use case diagram, the program comprising:

a use case specification configured to generate a procedure or method scenario performed in a use case diagram;
a test determination element extraction unit configured to separate a plurality of words of the scenario specified in the use case specification into input words, condition words, and output words according to the meaning of words to extract test determination elements;
a cause result graph generation unit configured to express the determination elements, which have been extracted by the test determination element extraction unit, by logical expressions to configure the relationships between the determination elements and express the configured relationships through a graph;
a determination table generation unit configured to select the coverage of the graph, which has been expressed by the cause result graph generation unit, to generate a table;
and
a test case generation unit configured to generate a test case by using the table which has been generated by the determination table generation unit.

expressing the determination elements, which have been extracted by the test determination element extraction unit, by logical expressions to configure the relationships between the determination elements, and expressing the configured relationships through a graph;
selecting, by a determination table generation unit, the coverage of the graph expressed by the cause result graph generation unit to generate a table;
and
generating, by a test case generation unit, a test case by using the table generated by the determination table generation unit,
wherein, in establishing, by the cause result graph generation unit, the relationships between the determination elements extracted by the test determination element extraction unit by expressing them by logical expressions, and expressing the established relationships through a graph, the number of determination elements, extracted by the test determination element extraction unit, is obtained by type and the number is repeated to dispose the determination elements by Input Type, Condition Type, and Output Type, and a graph is generated by connecting the relationships between the determination elements disposed by the element disposition unit.
