Method and apparatus for test coverage analysis

摘要

A method provides for a way to test coverage data used in testing small computing platforms by assigning unique signatures to each node in the control flow graph and embedding control function calls. Signatures are embedded into the program during compilation time using the custom parser. When the program is executed the “exercised” signatures sequence is checked for correctness and used for deriving test coverage metric. This metric is used for improving unit and black-box tests. Thus, a way to collect the path-based test coverage with minimal memory and code/size impact on target system is provided.

1. A method for conducting test coverage analysis comprising:
generating an enhanced source code instrumentation, wherein an instrumented code and a signature tree are generated during a compile time, the instrumented code including send signatures and the signature tree including a database of syntactically correct software paths; and processing the send signatures during a runtime, wherein a target application including the instrumented code executes and sends the processed send signatures to a host system where the processed send signatures are used in connection with the signature tree to analyze code coverage in a control flow graph.
