Revision 7e37a5918cbe18e6aca0751d9ff01c0e1dc3b055 authored by Akanksha Mahajan on 24 July 2020, 21:45:45 UTC, committed by Facebook GitHub Bot on 24 July 2020, 21:47:00 UTC
Summary: BackupableDBTest.RateLimiting test is failing due to timed out on our test server. It might be because of nested loops run sequentially that test different type of combinations of parameters. This patch converts the test into parameterized test so that all combinations can be tested out.
