While working in the expression editor you can test the current expression, in full or in part, to test that it works.
Doing this will actually execute the expression as written. This means that if the expression contains functions that, for example, call or modify external data or send an email, these processes will trigger just as if the expression had been executed during the model's run-time.
Implementation:
- Access the Expression Editor for the relevant expression.
- (Optional) Select one or more rows in the Editing Expression tab representing the parts of the expression you want to run.
If nothing is selected in the tab, the entire expression will run.
- Click the Run This option marked with the
icon, either from the editor's toolbar or by right-clicking anywhere in the tab. This will execute the expression and automatically open the Output tab, which will display the functions that were performed, their results, and any errors that may have occurred.
