For example, you can perform a function (for example, add) on two columns of data from a database or Microsoft Excel spreadsheet, then validate the function results against a third column of data in the data source.
Rational® Integration Tester supports four different test data types (database, directory, file, and Microsoft Excel).
If the test data source location is on a mapped network drive, you might get errors when running performance tests. To prevent any errors, ensure that the files are available on a local drive that can be accessed by Rational Integration Tester.
