Patent ID: 10713151

Abstract:
Program execution coverage is expanded by selectively capturing inputs and execution state information in a production environment after identifying test insufficiencies in a test environment. A program being tested has a non-covered portion and a covered portion. The non-covered portion includes code which is not exercised by a set of tests with regard to an execution coverage, e.g., path coverage, statement coverage, Boolean condition coverage, etc. A non-covered portion identifier identifies the non-covered portion, e.g., by noting breakpoint misses or static analysis constraint solution computational requirements. A trigger inserter inserts a trigger in the program, at a position which permits capture of data which aids exercise of the non-covered portion. A data capturer captures such execution coverage expansion data (“ECE data”) in response to trigger activation. Captured ECE data is automatically made available in the test environment, thus expanding code execution coverage of the program in the test environment.
