Valid and Invalid Column Names
As the columns of an Example Set directly correspond to the
<chevron_variabes> of Scenario Outlines, the logic that allows Example Sets to be managed in the data store has a few constraints on what can be used as a valid column name/chevron variable.
A valid chevron parameter name contains ONLY: - letters - numbers - underscores AND has at least one character that is not a number.
Therefore, column names may not contain any special characters but underscores nor can they be comprised of ONLY numbers.
