DGN

The Diagnostics mode allows messages to be entered into the test results log as they are encountered. It does not cause testing to be interrupted. DGN is automatically enabled at the beginning of each executed test script. It is not necessary to enable DGN with each test script; it may only be necessary to enable DGN if it was previously turned off in the test script for a particular section of testing.
