The Test Configuration’s Common tab controls test settings for actions that affect multiple analysis types.
The Common tab has the following settings:
Before Testing> Refresh projects: Determines whether projects are refreshed before they are tested. When a project is refreshed, C++test checks whether external tools have changed the project in the local file system, and then applies any detected changes. Note that when you test from the command line, projects are always refreshed before testing.
Incremental (build files changed since last build): Specifies that only the project files that have changed since the previous build should be rebuilt.
