Nullability of reference types in return type of 'ITestOutputHelper? DataProcessingServiceTests.Output.get' doesn't match implicitly implemented member 'ITestOutputHelper IGherXunitOutputProvider.Output.get' (possibly because of nullability attributes).

Non-nullable field '_apiClientMock' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

Non-nullable field '_repositoryMock' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

Non-nullable field '_queueServiceMock' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

Non-nullable field '_loggerMock' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

Non-nullable field '_dataProcessingService' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.
