A test harness may be part of a project deliverable. It may be kept separate from the application source code and may be reused on multiple projects. A test harness simulates application functionality; it has no knowledge of test suites, test cases or test reports. Those things are provided by a

When attempting to build an application that needs to interface with an application on a mainframe computer, but no mainframe is available during development, a test harness may be built to use as a substitute this can mean that normally complex operations can be handled with a small amount of
