I think this is pretty good! You've covered a large majority of the cases I wanted to see, but I think we could add a few more (see my comments). Generally, with tests, you want to test every corner of the thing being tested. I noticed that you tested the richtext "corner", but didn't test the HTML or the print attribution "corners". Testing every possible state permutation isn't necessary, but you generally want to be sure of the basics.

Good work! Just address the comments and I think we should be good to go :)

I also just noticed that there's an uncovered line, please add a test for line 80 to be sure that the empty string there is returned when appropriate :)

Thank you for reviewing the code even though you were busy...I made all the changes, hence review it whenever you are free :)

[akmadian]

Looks great! Thanks for working on this :)

This line causes an error running tests:

Error while running .clickElement() protocol action: element click intercepted: Element ... is not clickable at point (871, 102). Other element would receive the click
: ...

If you click on span.select, you will get the result you were expecting, and the tests run fine.

The same happens in LicenseDetailsCard

I think it passed for me before, too. Anyways, I opened an issue, and I think it's best if I assign it to you. Thank you for quick reply!
