I think @amitmiran137 already create a get_random_string function in test utils:

superset/tests/dashboards/dashboard_test_utils.py

Line 99 in 9a7fba8

def get_random_string(length):

Maybe consolidate?

[betodealmeida]

I don't think it's possible to import the get_random_string function here, so are you suggesting moving it outside the tests/ directory and reusing it both here and in the test?
