When a data-driven test script file, which is a file with the ending .g.t, is open in the editor, the Go to Testcase dialog box lists all the test cases that are available in the active script. Any listed data-driven test cases are prefixed with DD_.
To open the dialog box, click with the right mouse button into a .g.t file and select Go to Testcase.
Select the test case and then click OK to display the 4Test Editor with the cursor at the beginning of the test case that you have selected.
