Summary

When adding multiple validation rules the TestHelper’s ShouldHaveValidationErrorFor.WithoutErrorCode throws for each and any specified error code (see MWE below). The issue was introduced by d4773d2, but I’m not yet(?) powerful enough to suggest a fix.

Steps to Reproduce

namespace FluentValidation.Tests {

	using Xunit;
	using FluentValidation.TestHelper;
	public class WithoutErrorCodeIssue_Reproduce {

		class A {
			public A() { s = ""; }
			public double d = 0;
			public string s;
		}

		class AV : AbstractValidator<A> {
			public AV() {
				RuleFor(a => a.d).InclusiveBetween(1, 3); // remove this line this line to make the test pass
				RuleFor(a => a.s).NotEmpty();
			}
		}

		[Fact]
		public void Reproduce() {
			var vld = new AV();
			var res = vld.TestValidate(new A());

			res.ShouldHaveValidationErrorFor(a => a.s).WithoutErrorCode("abc");
		}
	}
}

I’ve pushed out 11.0.1 to nuget with the fix. Thanks @Aleksei-Pankratev-EPAM for your work on this
