You can test your survey by clicking on the View button from Edit. Your survey will be displayed in a pop-up and you can test and submit it without the responses being recorded.
You can also preview the survey in a new tab or window of your browser by clicking on the 'Test Link' button. Note that the link displayed should only be used for testing purposes and not to communicate to survey respondents. Survey responses will not be recorded when using the test link. A warning text is displayed at the top of the survey to remind you that it is a test: you will see Test Link. Survey responses are not saved. This text is not displayed when you publish the survey to respondents from the Publish menu.
