ITestWasbUriAndConfiguration.testCanonicalServiceName() failing now mockaccount exists

The test ITestWasbUriAndConfiguration.testCanonicalServiceName() is failing in its intercept

[ERROR] ITestWasbUriAndConfiguration.testCanonicalServiceName:656 Expected a java.lang.IllegalArgumentException to be thrown, but got the result: : "20.38.122.132:0"

Root cause is: the mock account in AzureBlobStorageTestAccount.MOCK_ACCOUNT_NAME is "mockAccount.blob.core.windows.net" and someone has created that account

This means it resolves
nslookup mockAccount.blob.core.windows.net
Server: 172.18.64.15
Address: 172.18.64.15#53

Non-authoritative answer:
mockAccount.blob.core.windows.net canonical name = blob.dsm08prdstr02a.store.core.windows.net.
Name: blob.dsm08prdstr02a.store.core.windows.net
Address: 20.38.122.132
