Coverage images are identifiers for the coverage data associated with a test run. The filter must be set to the correct coverage image to present information from coverage widgets, such as the Coverage Summary or Coverage Trend widgets (see Coverage - Line Widgets).
Coverage images are automatically created when a Parasoft code analysis and test execution tool (C/C++test, dotTEST, or Jtest) reports test data to DTP with the report.coverage.images
setting configured. See the Parasoft tool documentation for details. You can associate up to five coverage images with a filter.
