2. Configuration creation

FluentValidation.Validators.UnitTestExtension allows you to build test configuration for FlunetValidation rules. You can prepare test configuration in two ways:

• by using BaseVerifiersSetComposer
• creation array of IValidatorVerifier

I recommend to use first apporach beacuse it is more comfortable than second one.

BaseVerifiersSetComposer

BaseVerifiersSetComposer is class that provide generic methods for configuration construction. You cannot create instance of this class directly. Instead of constructir you should use static method Build(). This method should be used each time when you need to create new configuration.

After that you can use one of following methods for adding validation verifiers:

• AddPropertyValidatorVerifier<TPropertyValidator>() - TPropertyValidator should implement IPropertyValidator
• AddPropertyValidatorVerifier<TLengthValidator>(int min, int max) - TLengthValidator should implement ILengthValidator
• AddPropertyValidatorVerifier<TRegularExpressionValidator>(string expression) - TRegularExpressionValidator should implement IRegularExpressionValidator
• AddPropertyValidatorVerifier<TRegularExpressionValidator>(string expression, RegexOptions options)
• AddPropertyValidatorVerifier<TRegularExpressionValidator>(Regex regex)
• AddEqualValidatorVerifier<TEqualValidator, T, TProperty>(object valueToCompare, Comparison? comparison, MemberInfo memberToCompare) - verifies EqualValidator or NotEqualValidator
• AddComparisonValidatorVerifier<TComparisonValidator, T, TProperty>(object valueToCompare, Comparison? comparison, MemberInfo memberToCompare)- verifies LessThanValidator or LessThanOrEqualValidator or GreaterThanValidator or GreaterThanOrEqualValidator
• AddBetweenValidatorVerifier<TBetweenValidator>(IComparable from, IComparable to)
• `AddPrecisionScaleValidatorVerifier<TPrecisionScaleValidator, T>(int scale, int precision, bool ignoreTrailingZeros) - TPrecisionScaleValidator should inherit from PrecisionScaleValidator
• AddEnumValidatorVerifier<TEnumValidator, T, TProperty>()
• AddChildValidatorVerifier<T, TProperty>()
• AddExactLengthValidatorVerifier<T>(int length)
• AddMinimumLengthValidatorVerifier<T>(int min)
• AddMaximumLengthValidatorVerifier<T>(int max)
• AddVerifier(IValidatorVerifier ruleVerifier) - allows usage of your own implementer Verifier
• AddPlaceholderVerifier() - insterts dummy verifier that does not check anything

As type you must insert one of validators provided by FluentValidation or your validator that you have implemented by yourself. Togheter with that you are able to instert also parameters when provided validator type needs it.

And finally you must execute Create() method. It transfomrs configuration into IValidatorVerifier array. Such created configuration can be used in unit tests.

Example

BaseVerifiersSetComposer.Build()
	.AddPropertyValidatorVerifier<NotNullValidator<Person, string>>()
	.AddPropertyValidatorVerifier<NotEmptyValidator<Person, string>>()
	.AddPropertyValidatorVerifier<LengthValidator<Person>>(0, 20)
	.Create());

Manual configuation

Other option is to create configuration manually by providing array of objects that implements IValidatorVerifier interface.

List of already implemented verifiers can be found under following link: Validator verifiers.

Example

new IValidatorVerifier[]
{
	new TypeValidatorVerifier<NotNullValidator<Person, string>>(),
	new TypeValidatorVerifier<NotEmptyValidator<Person, string>>(),
	new LengthValidatorVerifier<LengthValidator<Person>>(0, 20)
});
