test: sort imports and use "new" string formatting

Followed PEP8 and PEP3101 rules (#8079)
Imports re-ordered by Alphabetical Standarts for following PEP8
Old type string formattings (" example %s " % exampleVar ) re-writed as new type string
formattings ( " example {} ".format(exampleVar) ) for following PEP3101
