Success URLs are a great way to find out if a participant does or does not get to the expected URL. It is not a way for a participant to finish a task, as not getting to the "success URL" is equally important information.
The tester is not aware if they have reached the success URL and is told to complete a task when they *think* they are done.
What if the Starting URL and the Success URL happen to be the same:
You can also have a scenario where the starting URL is www.one.com, then task 2 starting URL is www.one.com/two. The success URL can be shown as www.one.com and it still works even though that was the starting URL for task1.
Wildcards: Let’s say you task is deemed successful if the tester navigates to a particular URL during the task, but it could be more than 1 particular URL. You can use a wildcard character to match any URL.
Will match anything starting with http://mysite.com/shoes/ and the star at the end means anything after. For example, it will match http://mysite.com/shoes/redshoe and http://mysite.com/shoes/blueshoe
You can place the wildcard character anywhere, not just at the end.
