Special functions in datafiles ============================== Datafiles (or in Excel Simple format simply a tab "data") generally hold the data for one or more testcases. The first line of the datafile holds the header line. Each cell in the header must have a unique value and acts as variablename, which you can use for checking, for IF-Statements or as values to write into fields or compare with assertions. Additionally there are some reserved names that deliver the following functionality: .. list-table:: Field names in Datafiles and their function :widths: 25 75 :header-rows: 1 * - Field name - Description * - ``TC Expected Error`` (!sic) - When set to value ``X``, the Test case is supposed to fail.
