C# 测试依赖于其他属性的验证属性
我创建了一个C# 测试依赖于其他属性的验证属性,c#,asp.net-mvc,unit-testing,moq,C#,Asp.net Mvc,Unit Testing,Moq,我创建了一个ValidationAttribute,它基本上检查另一个属性是否有值,如果有,该属性将成为可选属性。假设此属性依赖于另一个属性,那么如何在ValidationContext OptionalFattribute [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = false)] public class OptionalIfAttribute : ValidationAttrib
ValidationAttribute
,它基本上检查另一个属性是否有值,如果有,该属性将成为可选属性。假设此属性依赖于另一个属性,那么如何在ValidationContext
OptionalFattribute
[AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = false)]
public class OptionalIfAttribute : ValidationAttribute
{
#region Constructor
private readonly string otherPropertyName;
public OptionalIfAttribute(string otherPropertyName)
{
this.otherPropertyName = otherPropertyName;
}
#endregion
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
var otherPropertyInfo = validationContext.ObjectType.GetProperty(this.otherPropertyName);
var otherPropertyValue = otherPropertyInfo.GetValue(validationContext.ObjectInstance, null);
if (value != null)
{
if (otherPropertyValue == null)
{
return new ValidationResult(FormatErrorMessage(this.ErrorMessage));
}
}
return ValidationResult.Success;
}
}
测试
[Test]
public void Should_BeValid_WhenPropertyIsNullAndOtherPropertyIsNull()
{
var attribute = new OptionalIfAttribute("OtherProperty");
var result = attribute.IsValid(null);
Assert.That(result, Is.True);
}
最简单的方法就是这样
[Test]
public void Should_BeValid_WhenPropertyIsNullAndOtherPropertyIsNull()
{
var attribute = new OptionalIfAttribute("OtherProperty");
//**********************
var model = new testModel;//your model that you want to test the validation against
var context = new ValidationContext(testModel, null, null);
var result = attribute.IsValid(testModel, context);
Assert.That(result.Count == 0, Is.True); //is valid or Count > 0 not valid
}
这将在不使用具体模型类的情况下对其进行测试:
[TestMethod]
public void When_BothPropertiesAreSet_SuccessResult()
{
var mockModel = new Mock<ISomeModel>();
mockModel.Setup(m => m.SomeProperty).Returns("something");
var attribute = new OptionalIfAttribute("SomeProperty");
var context = new ValidationContext(mockModel.Object, null, null);
var result = attribute.IsValid(string.Empty, context);
Assert.AreEqual(ValidationResult.Success, result);
}
[TestMethod]
public void When_SecondPropertyIsNotSet_ErrorResult()
{
const string ExpectedErrorMessage = "Whoops!";
var mockModel = new Mock<ISomeModel>();
mockModel.Setup(m => m.SomeProperty).Returns((string)null);
var attribute = new OptionalIfAttribute("SomeProperty");
attribute.ErrorMessage = ExpectedErrorMessage;
var context = new ValidationContext(mockModel.Object, null, null);
var result = attribute.IsValid(string.Empty, context);
Assert.AreEqual(ExpectedErrorMessage, result.ErrorMessage);
}
[TestMethod]
当两个属性重置时公共无效\u SuccessResult()
{
var mockModel=new Mock();
Setup(m=>m.SomeProperty).Returns(“something”);
var属性=新的OptionalFattribute(“SomeProperty”);
var context=新的ValidationContext(mockModel.Object,null,null);
var result=attribute.IsValid(string.Empty,context);
Assert.AreEqual(ValidationResult.Success,result);
}
[测试方法]
当\u SecondPropertyIsNotSet\u ErrorResult()时公共无效
{
常量字符串应为ErrorMessage=“哇!”;
var mockModel=new Mock();
Setup(m=>m.SomeProperty).Returns((string)null);
var属性=新的OptionalFattribute(“SomeProperty”);
attribute.ErrorMessage=ExpectedErrorMessage;
var context=新的ValidationContext(mockModel.Object,null,null);
var result=attribute.IsValid(string.Empty,context);
Assert.AreEqual(ExpectedErrorMessage、result.ErrorMessage);
}
我正在使用下面的代码测试我的自定义验证器类
[TestMethod]
public void IsValid_Test()
{
var modelObj = new youModelClass {
requiredProp = value
};
var validatorClassObj = new yourValidatorClass();
var validationResult = validatorClassObj.GetValidationResult( valueToValidate, new ValidationContext( modelObj ) );
Assert.AreEqual( ValidationResult.Success, validationResult );
}
很高兴知道是否还有其他的测试方法。这是测试模型,而不是验证属性,虽然我知道,但如果没有其他方法,您就无法测试其中一种,当然模仿
验证上下文
也可以。但您的意图是“已经创建了一个uValidationAttribute,该属性基本上检查另一个属性是否有值,如果有,该属性将成为可选属性。”u通过模拟,您将如何证明这一点,因为您从-validationContext.ObjectType和validationContext.ObjectInstance获取对象。请始终思考我的测试给出了什么。。。。
