Seems like you should also make sure it's less than 1050

Should we test parameter aliases? It seems it is a general feature and we should test the feature in special tests but not every cmdlet and every alias.

In general, we should validate the alias is correct, but shouldn't repeat every test for the parameter and its alias. -ms is a pretty simple case, so it's hard to not repeat the test (using -TestCases is probably better here). For parameters with more complex behavior, I think it would be sufficient if some cases used the parameter while others used the alias.

Ilya (@iSazonov) - As a matter of principle - we avoid testing the parameter binder in cmdlet specific tests.

Personally I don't ask for any tests for an alias - the test isn't covering any new code, but I understand the concerns of those asking for the test, so I don't complain about it either.

If we're worried about parameter's aliases, we could make a common test for all of them, just like we did for the cmdlets and their aliases as < cmdlet, parameter, alias, platform(?) >.

It's not a big problem, people mostly never remove code anyway and if they did, it should be caught during the PR, but it's a nice idea.
