you're getting text from le element found by that text? no reason in this method, we need or to find filter name by another locator and assert text or assert that element found by text is visible 1 we agreed use assertions only inside test classes
2I meant create this method with modal element(s) (for example use addFilterCodeModalTitle) shouldBe(visible) only
3 do not forget that we're waiting enabled and disabled elements are visible too
4 looks according to AC disabled element is only addFilterBtnAddFilterMdl, so we can create isAddFilterBtnAddFilterModalEnable() method instead of getAllAddFilterModalDisabledElements()
 Done I refactored assertion block of code, and hope that I understood you correctly
[e2e] Checking Filter adding within Topics/Topic/Messages with filled required fields
Autotest implementation for:
https://app.qase.io/project/KAFKAUI?view=1&suite=5&previewMode=side&case=12

Description:
Checking Filter adding within Topics/Topic profile/Messages tab

Preconditions:
Login to Kafka-ui application

Open the 'Local' section

Select the 'Topics'

Steps:
1 Open any Topic's profile
2 Turn to 'Messages' tab
3 Press 'Add Filters'

Expected result
'Add filter ' pop up should open with following information:
''Saved filters' link, 'Filter code' field, 'Save this filter' checkbox (unchecked by default), 'Display name' input field, 'Cancel' active and 'Add' disabled by default buttons

4 Fill 'Filter code' input field

Expected result
'Add' button should become active

5 Press 'Add' button

Expected result:
1 'Add filter' pop up should disappear
2 New filter should appear near '+Add Filters' button
3 Corresponding data should display
