This test case was previously skipped because it fails randomly in Linux environment. Details are in #10667
Please enable it and fix the error. Thanks

@isra-fel I did see you skipped it, however i could not reproduce it in my linux VM. So I still do not understand the exact root cause of it, however i feel why it might be happening. But thing is the failure is for adlsaliastest and you have skipped it for adlstest.

Now if you see there are two versions of test AdlsAliasTest and AdlsTest. Both are exact replicas functionally, only difference is one of them uses alias commandlet names. And in most of the logs i see "Export-AdlStoreChildItemProperties" failing for alias. As a part of this commandlet we write output to a local path. So i suspect adlstest and adlsaliastest are interfering with each other. Reason why i think is because adlsaliastest was the one failng, but you disabled adlstest and it started passing more. I still do not know why they are interfering.

What I will do is try to comment out "Export-AdlStoreChildItemProperties" in adlsaliastest.testfilesystem (since thats the one failing) and enable the adlstest.testfilesystem. But I dont think this PR is the correct place to fix this since this adresses a different bug.

I will send out a different PR after this with the proposed change.

Thanks for all your explanation, it makes sense to me.
