Sandra.SimpleValidator

Sandra.SimpleValidator is designed to be... a simple validator, nothing more. It has no ability to inject repositories and query the database to validate stuff. It has no ability to generate JavaScript validation.
Sandra.SimpleValidator is designed to be... a simple validator, nothing more. It has no ability to inject repositories and query the database to validate stuff. It has no ability to generate JavaScript validation.
It's purely used to validate a Model/ViewModel or DTO, or something that requires super simple validation such as Required, Minimum Length, etc.
To use simply create a validator:
public class UserValidator : ValidateThis<User>
{
public UserValidator()
{
For(x => x.UserName)
.Ensure(new Required());
For(x => x.Email)
.Ensure(new Required())
.Ensure(new Email());
For(x => x.Locale)
.Ensure(new Required());
}
}
Tell the validation service about any validators.
// this will look at the assembly associated to the generic argument and find all validators
ValidationService.RegisterAllFrom<UserValidator>();
Then you can inject the ValidationService
into your Controller
or NancyModule
public class HomeModule : NancyModule
{
public HomeModule(ValidationService validate)
{
Get["/"] = _ =>
{
var user = this.Bind<User>();
var validationResult = validate.This(user);
if (validationResult.IsInvalid)
{
//Handle errors with
//validationResult.Messages
return "Validation has fails :(";
}
return "Validation was successful :)";
};
}
}
And that's it. The ValidationService
method is virtual so you can mock and test it, and unit testing your Validators is easy too, simply create an instance of the validator and call validate on the model you want to test.
[Fact]
public void Given_Valid_Model_Should_Return_IsValid_As_True()
{
var validator = new TestClassValidator();
var model = new TestClass
{
Name = "Hello World",
Thing = "Thing!"
};
var result = validator.Validate(model);
Assert.True(result.IsValid);
}
