Do we have tests for this regex? If not, we should create a few.

Do we have tests for this regex? If not, we should create a few.

@TobiGr I thought about it at first too because we don't currently have them and this seems easily testable. But the code combines recognizing the hashtags (or links) and applying the onClickListeners to the UI making it very hard to add tests.

I would not put the burden on a first timer

@XiangRongLin I thought more of basic unit tests to ensure the regex is working as expected. Not more. But if you think this should be done in a separate PR, that's not a problem at all.
@Jaspann It's up to you to decide whether you want to create unit tests or not :P

[Jaspann]

@TobiGr I don't know really anything about unit testing so I would prefer not to.

@XiangRongLin I'm sorry, I found some problems with this solution and want to commit a solution that is much more accurate to how hashtags work. Should I commit here or close this PR and open a new one? Once again I am sorry, as this is my first time committing to a public repo and I don't really know how it works.
