There are three types of diagnostic messages:
![]() |
Informational message. These are friendly reminders or additional information to help configure setups. They have no impact on test runs. |
![]() |
Warning. This indicates a possible error. Warnings may or may not cause problems with the test engine. They may also indicate configuration inconsistencies or ambiguities. Users should investigate these warnings carefully and take any action if necessary. Depending on system preferences, a test run may or may not be started with warning level errors. |
![]() |
Error. These are errors that prevent a test run from being started. |
Diagnostic messages are recalculated upon completion of individual values. In the case of a spreadsheet interface, re-validation takes place only after the cell is completed and focus moves away from that cell. While the cell is considered to be in edit mode, no validations take place.
Upon a cell changing, the setup as a whole is validated. All channels are iterated and the rules applied at every level. If any defaults or rippling of data due to a change in a cell, then this will be done before the validation process starts. If the validation finds any errors or messages, it highlights the appropriate cell/rows and adds a message to the diagnostic messages list. If existing errors have been addressed and no longer need to display, the color and the message will be removed from the list.
