Updated all test methods to use asynchronous programming with
`async` and `await`, replacing synchronous calls with
`.GetAwaiter().GetResult()`. This improves readability and
aligns with modern C# practices.
Renamed test methods to reflect their asynchronous nature and
better describe their behavior. Updated exception handling to
validate HTTP methods and request URIs while maintaining
original assertions.
Applied changes consistently across multiple test classes,
including `CommonApiTests`, `EndpointAuthApiTests`,
`EndpointParamsApiTests`, `EndpointsApiTests`,
`ProfileApiTests`, `RecActionApiTests`, and `ResultApiTests`.
Added the `EndpointAuthApiTests` class to test the `EndpointAuth` API.
Tests include:
- Dependency injection resolution (`ReCClient_endpoint_auth_api_is_resolvable_through_dependency_injection`).
- `CreateAsync` behavior with minimal payload.
- `UpdateAsync` behavior with an unknown ID.
- `DeleteAsync` behavior, ensuring payload is sent as a query string.
Introduced necessary `using` directives and utilized the `CreateScopedClient` helper method for scoped client creation. Added exception handling to validate API method behavior and ensure proper assertions on exceptions.
