Generally, Qualaroo can be tested in an environment that has a domain associated with it (i.e. dev.website.com will work, 18.104.22.168 will not work). We need to be able to point the code to a web address in order to get it to work properly.
If you have a testing environment set up in such a way that you can target it via URL, even if it requires a login, intranet or other security measure, then you can test the Qualaroo survey in this environment.
Using the Simple URL field, you can target all domains (testing.com, testing.dev) and localhost. Localhost will only work when it can also connect to the internet.
Port numbers cannot be used in the Simple URL field, and only one wildcard can be used.
Using the Advanced URL field, you can target all domains (testing.com, testing.dev) and localhost, with or without Port Numbers. Localhost will only work when it can also connect to the internet.
