Review Comment:
   The case below seems OK. If `ViewUtil.isViewCatalog(catalog)` is not 
satisfied, it will just skip this case.
   
   For `case ShowViews(UnresolvedNamespace(Seq()), pattern, output)`, if 
`ViewUtil.isViewCatalog(catalog)` is not satisfied, it goes to the case below 
`case ShowViews(UnresolvedNamespace(CatalogAndNamespace(catalog, ns)), pattern, 
output)`, it failed in `CatalogAndNamespace(catalog, ns)`
