Using reflection to test private methods makes tests brittle and tightly coupled to implementation details. Consider making the validation method internal and using InternalsVisibleTo attribute, or testing the validation indirectly through public methods.

Multiple test methods use reflection to access private methods. This pattern is repeated throughout the test file, making tests fragile to refactoring. Consider exposing these methods as internal or testing through public API behavior.

The comment suggests this test assertion was 'fixed' but the comment indicates uncertainty about the expected behavior. The test should verify the actual expected error code based on the implementation, not guess based on comments.
| Assert.Equal(ConnectorErrorCodes.GetStatusError, result.Error?.ErrorCode); // Fixed: Base class catches exceptions and converts to standard error code | |
| // The base class catches exceptions from GetConnectorStatusAsync and returns ConnectorErrorCodes.GetStatusError (see FacebookMessengerConnector.GetStatusAsync implementation). | |
| Assert.Equal(ConnectorErrorCodes.GetStatusError, result.Error?.ErrorCode); |

The FacebookMessengerSchemaFactory class is missing copyright header and XML documentation comments that are present in other files in the project.

The EmailAddress endpoint type is allowed for sending with a comment indicating it's just to pass validation, but this could be confusing for API consumers. Consider either properly supporting email addresses or removing this endpoint type from the schema.
