How can you customize the columns shown in Test Cases?

• A. Columns are fixed and cannot be added.
• B. Use the Column Settings dialog to adjust the view.
• C. You must edit the underlying database to customize columns.
• D. Right-click the header row and select "Column Chooser" to add columns.

Answer: (D)

Customizing the grid view is about choosing which fields you want to see in the Test Cases list. In Tosca, the straightforward way to add or remove columns is by using the Column Chooser, which you access by right-clicking the header row of the Test Cases grid. From there, you can select which columns to display, letting you tailor the view to show exactly the information you need. This method keeps changes local to your workspace and doesn’t touch any data storage.

So this is the best approach because it directly changes the visible columns in the UI in a quick and safe way. The idea that columns are fixed isn’t accurate, and editing the underlying database isn’t how you customize the view. There might be other dialogs related to columns in some contexts, but the standard, efficient way to add columns in Test Cases is via the Column Chooser from the header.
