[PATCH] selftests: tc-testing: preserve list order when removing duplicates

Posted by mr.navi8680@gmail.com 1 month, 3 weeks ago

From: Naveen Anandhan <mr.navi8680@gmail.com>

Using set() removes duplicates but breaks ordering.
Test output should be deterministic, so replace with dict.fromkeys().
