Rules of independent properties are expected in tested property

[mjuen]

Hello,

in the code underneath I try to check if the validation rule GreaterThan(0) for the id of the Driver object in a Shift is present. Unfortunately the test always fails with the message: Expected collection to contain 1 item(s) because (number of rules for property), but found 3.

It seems like somehow the rules for Assistant.Id and Trainee.Id influence the ones for Driver.Id.

public class BugTests
{
	private readonly DutyRosterValidator dutyRosterValidator =
	  new DutyRosterValidator();

	[Test]
	public void DriverId_ShouldHaveAllValidators()
	{
		dutyRosterValidator.ShouldHaveRules(x => x.Driver.Id,
			BaseVerifiersSetComposer.Build()
				.AddPropertyValidatorVerifier<GreaterThanValidator>(0)
				.Create());
	}

	public class User
	{
		public int Id { get; set; }
	}

	public class Shift
	{
		public DateTime StartTime { get; set; }

		public DateTime EndTime { get; set; }

		public User Driver { get; set; }

		public User Assistant { get; set; }

		public User Trainee { get; set; }
	}

	public class DutyRosterValidator : AbstractValidator<Shift>
	{
		public DutyRosterValidator()
		{
			RuleFor(x => x.Driver.Id)
				.GreaterThan(0)
				.When(x => x.Driver != null);

			RuleFor(x => x.Assistant.Id)
				.GreaterThan(0)
				.When(x => x.Assistant != null);

			RuleFor(x => x.Trainee.Id)
				.GreaterThan(0)
				.When(x => x.Trainee != null);
		}
	}
}
