Explain Data Table in QTP.

The Data table is similar to Microsoft Excel Spreadsheet where you can store and use the data in its cells also you can use formulas in these cells.  The DTsheet and DTparameter can be used to manipulate the data in any cells of the data table.

The usage of Data table parameters and output values helps to do data driven test that runs multiple times.

The QTP creates a run time data table which is a live version of the data table associated with the test which helps to see any changed occurred to the data table. When the run session ends the run time data table closes. The final data from the run time data table is displayed in the Run time data table in the Test results window.

Data table has two types of data sheets,

1)      Global

The data can be stored in global tab when the data is made available in all actions performed in the test.

2)      Action

The data can be stored in the action tab when the data is made available for that particular action in the test.
