To access data stored in Microsoft Office Excel files in your tests, you can use DB Table variables. These variables store links to Excel files and provide serial access to data rows stored in these files.
The DB Table variables provide read-only access to Excel data. You cannot use them to change values stored in data storages. To change Excel data during tests, you can use the
Excel.Application COM object. For more information, see Working With Excel Files via COM.
To access data in Excel files, you must have Microsoft Office 12.0 Access Database Engine OLE DB Provider installed on your computer. Make sure the “bitness” of this data provider (32- or 64-bit) is the same the TestComplete “bitness”, otherwise, you will get the “The needed data source driver is not installed...” error message. To learn more, see Microsoft Office Excel Data Connectivity.
You can create these variables on the Variables page of the project, project suite or keyword test editor or when adding specific test operations to a test. When creating a DB Table variable, you specify an Excel file and its worksheet, the data of which the variable will retrieve.
You can use DB Table variables both in scripts and in keyword tests.
Typically, in keyword tests, you use the Data-Driven Loop operation to iterate through Excel file rows. To learn how to use the Data-Driven Loop operation in your tests, see Creating Data-Driven Loops and Data-Driven Testing With Keyword Tests - Tutorial.
