We try to run a test suite in Test Runner and it ends prematurely as successful. We do not know why it ends early as there is not an error message.

This is caused by the max errors set in the staging document.
Refer to section "Staging Document Editor" in the documentation of the DevTest release you are running.
Increase the max errors to the number required or set it to unlimited by setting it to 0
