Regex to match specific domain and it's subfolder

I want to match a particular domain and its subdomain, no matter how it's entered. In the following example, I want to match all ´test.comif nothing comes after it (only a slash or query strings) OR if a specific folder follows it in this case it's named as:subfolder`. Again the subfolder could have / or query strings after.

Domain Match
test.com match
https://test.com match
https://test.com?foo=bar match
https://test.com/ match
https://test.com/?foo=bar match
https://www.test.com match
https://www.test.com/subfolder match
https://www.test.com/subfolder/ match
https://www.test.com/subfolder/?foo=bar match
test.com/subfolder match
https://www.test.com/foo no match
test.com/foo no match
https://www.test.com/jason no match
https://www.test.com/jason?foo=bar no match

Right now I have the following regex:

^(?:\S+://)?[^/]+/?$

The problem though is that it matches ANY domains, which is not what I need. I want to match a specific domain and a specific subfolder.

How is this possible?

You may use this regex:

^(?:https?://)?(?:www\.)?test\.com(?:/subfolder)?/?(?:\?\S*)?$

With your shown samples, could you please try following.

^(?:(?:https?:\/\/)(?:www\.)?)?test\.com(?:(?:(?:\/)?(?:\/subfolder\/?)?(?:\/\?\S+\/?)?)?(?:\?\S+)?)?(?:\/)?$
