Abstract

Systems and methods for coverage analysis using context information are described. The systems and methods can be used to obtain program code and test information for testing the program code, the test information associated with context information for providing context for testing the program code. Coverage information can be generated by testing the program code according to the test information. A first association can be generated between the context information and the test information. A second association can be generated between the context information and the program code. A third association can be generated between the coverage information and the test information. A subset of the coverage information can be determined based on the third association and a fourth association between the test information and the program code determined based on the first and second associations. An indication of the subset of the coverage information can be displayed.

Claims21

Dependent claims

A method comprising, obtaining program information including program code and test information for testing the program code, the test information associated with context information for providing context for testing the program code, wherein:

the program code comprises multiple code portions and the program code simulates a system;
and
the context information comprises at least one contextual item for a subset of the system that is part of, but not all of, the system;
generating coverage information by testing the program code according to the test information, wherein the coverage information comprises, for each of the multiple code portions, associated coverage result information;
determining a first association that identifies a subset of, but not all of, the test information for the subset of the system;
determining a second association that identifies a code portion of the multiple code portions of the program code that simulates the subset of the system;
determining a third association between the coverage result information of the coverage information and the test information;
determining a subset of the coverage information for the subset of the system based on the third association and a fourth association that identifies that the subset of the test information is for testing the code portion of the program code that simulates the subset of the system associated with the at least one contextual item of the context information, wherein:
the subset of the coverage information is part of, but not all of, the coverage information;
the fourth association is determined based on the first and second associations;
and
the subset of the coverage information is the coverage result information for the code portion of the program code that simulates the subset of the system associated with the at least one contextual item of the context information;
and
providing instructions to display an indication of the subset of the coverage information.
