remove commented line, pls locator is too abstract, let's try to specify it var name should start from low letter if it's not constant this class looks overloaded with a lot of enums
created pls kafka-ui-e2e-checks/src/main/java/com/provectus/kafka/ui/pages/topic/enums/ENUM_CLASS_FOR_EVERY_SINGLE_ENUM_SEPARATELY.java let's place those methods above inner class isDeleteCustomParameterBtn() -> isDeleteCustomParameterButtonEnabled Fixed Fixed. Fixed. Fixed. Fixed. Fixed. isTrue() or isFalse() missed, assertion is incomplete really don't understand why do we need to assert this and 296 line
i believe we should leave 291 and 297 lines assertion, but we don't need to do this softly Fixed. Fixed.
[e2e] Checking requiredness of Custom parameters within 'Create new Topic'
Autotest implementation for:

https://app.qase.io/case/KAFKAUI-6

Description:
Checking requiredness of Custom parameters' within 'Create new Topic'

Pre-conditions:

Pre-conditions
Login to Kafka-ui application

Open the 'Local' section

Select the 'Topics'

Redirect to 'Create new Topic' page with click on '+ Add a Topic' button from 'All Topics' page

Post-conditions:

Empty value

Steps:
1 Click on '+ Add Custom Parameter' button
2 Click on 'Custom Parameter *'
3 Select the Custom Parameter value
4 Remove the "Value" field's data

Expected result:
1 Should appear 'Custom Parameter' dropdown field, 'Value' input field and 'x' delete button
2 Should open Custom parameters list
3 Select the Custom Parameter value
4 Should appear "Value is required" validation message for empty 'Value'
