Shell/Bash - equality check between strings returns 1 on match-CodePudding

I'm trying to compare output of a cli command "successful" with simple test = $? but getting 1 even though values match. I did the same on hard-coded example and works fine.

Should the variable that stores cli's output be in different wrapping?

#ri status:
ri_status=`aws dms describe-connections --filter Name=replication-instance-arn,Values=$ri_arn --query=Connections[0].Status --region us-east-1`

#returns "successful"
echo $ri_status

#this returns 0
test "successful" = "successful"
echo $?

#this returns 1
test $ri_status = "successful"
echo $?
