This is possible thanks to the "Execute Questionnaires" option. To access this option, you must:
Go to the process configuration where the test you want to run is.
Place the candidate in the process configuration panel, and click on the "options" button, located to the right of the candidate.
Click on the "Execute Questionnaires" option.
Click on the "play" icon, located to the left of the test you want to run.
When the confirmation notice appears, check the information and click "accept". You will be automatically logged out of the administrator module and the test will start, so that the candidate can take the test on that same computer.
