Remove all usage of FormattableMarkup in tests apart from explicit tests of that API

Closing as a duplicate of 📌 [meta] Remove usage of t() in tests not testing translation Active and moving credit.

I think I should not have closed this. I was probably focused on t() at the time but today I see uses of FormattableMarkup in tests where it could be removed. And I guess I didn't read #74.

Sorry folks.

Thanks everyone for your effort.

It looks like title and summary are different, as already mentioned at #51, and it's extremely difficult to understand what is happening here/
As I understand original issue was "Remove all usage of SafeMarkup::format() and format_string() in tests apart from explicit tests of those methods".

I checked patch #78, at the top we remove t() function.

My suggestion:
revert issue title to original value and close this issue, and create new one with focus to remove FormattableMarkup.

In order to provide code contribution is better to use child issue #3227598: Remove uses of FormattableMarkup in kernel test assertions → .

Since SafeMarkup was replaced by FormattableMarkup I think we can continue with this issue. There is already a child issue here for Kernel tests. Another one is needed for Functional tests.

As I understand #51, the follow up was to manage the number of changes. Since then, a separate issue has been created for Kernel test, which will help manage the scale of the changes. So, I don't think the tag is necessary any more.
