Analyze uncovered core test cases

[JiaqiZhang-Dev]

Our existing spector tests are core & specialized, with the goal that the pass rate of core test cases should be ~100%.

The following are the cases where the unit tests were not covered:

• [Done] exist config:'resources': ['azure/resource-manager/resources', 'factory-gather-all-params=false']
  Resources->ExtensionsResources:createOrUpdate、delete、get、listByScope、update

• ctors for API key not supported Auth with API key is not recommended because of SFI
  Authentication->ApiKey:valid、invalid
  Authentication->Http->Custom:valid、invalid
  Authentication->Union:validKey

• TODO: Fix multipart/form codegen #1445 (issue status:open) Multi-part form data will be fixed if there is any service’s ask
  Payload->MultiPart

• TODO: [spector] add support for routes #1730 (issue status:open) Uri template is rarely used
  Routes:fixed、InInterface
  Routes->PathParameters
  Routes->QueryParameters

• not a real scenario, will be fixed if there is any service’s ask
  Type->Model->Inheritance->NestedDiscriminator
