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`.
Introduced the `CommonApiTests` class to validate the behavior of the `ReCClient`'s `Common` API.
- Added `using` directives for namespaces related to procedures and commands to support the new tests.
- Verified dependency injection resolution for `ReCClient` and its `Common` API.
- Added tests for `CreateAsync`, `UpdateAsync`, and `DeleteAsync` methods to ensure proper handling of payloads and expected behavior:
- `CreateAsync_with_invalid_action_payload_throws_or_completes`: Tests invalid payload handling for `CreateAsync`.
- `UpdateAsync_with_body_payload_throws_or_completes`: Tests payload handling for `UpdateAsync`.
- `DeleteAsync_sends_payload_as_query_string`: Verifies query string construction for `DeleteAsync`.
