Remove translations from all tests

I'll work on a patch.

Patch provided. Please review.

Hi people,
I am not sure if this is right, but we need to remove all usages of t() in tests ?
If yes, and after I ran 'git grep' this is the output:

$ git grep '\bt(' `find -type d -name tests` tests/search_api_test

$this->submitForm([], t('Delete'));

tests/src/Functional/IntegrationTest.php:
$this->assertSession()->responseContains(t('The search server %name has been deleted.', ['%name' => $server->label()]));

There are several usages of t() function in tests folder yet.

#5 is correct, we need to remove it from the actual tests. Keeping this issue at NW but restoring novice tag.

Thanks for the hint.

Attached updated patch.

I tested the 'remove_translations_from_all_tests-2870988-13.patch' patch and it looks nice for me.
