Testing Coverage Tools
SD supplies test (or code) coverage tools for arbitrary procedural languages. Such tools provide statistics and detail information about which parts of an application program have been executed (usually by a test suite). This information is invaluable to software teams to help determine the readiness of software for actual use. The type of coverage information collected is branch coverage, which subsumes statement coverage.
Test coverage tools may also be used to locate application functionality. One simply exercises the functionality of interest, and the test coverage tool indicates what part of the application code is executed. This a a very effective way to locate functionality in a large, poorly understood system.
SD's test coverage tools operate by inserting language-specific probes for each basic block in the source files of interest before compilation/execution. At execution time, the probes record which blocks get executed ("coverage data"). On completion of execution, the coverage data is typically written to a test coverage vector file. Finally, the test coverage data is displayed on top of browsable source text for the system under test, enabling a test engineer to see what code has (not) been executed, and to see overall statistics on coverage data.
Products :

probe)
* Can accumulate coverage data from multiple execution runs
* Browsable source files overlayed with collected coverage information
* Produces by application, subsystem and file
* Test Coverage delta computation and display, to enable test case
minimization
