StringLengthAttribute support in AutoFixture

2011-09-18 | #autofixture 

Continuing the support of DataAnnotations as described here, there is now added support for the StringLengthAttribute class. Starting with version 2.4.0, when this attribute is applied on a data field it can specify the maximum length of characters that are allowed.

Let's take as an example the following type:

public class StringLengthValidatedType
    public string Property { get; set; }

Prior to version 2.4.0 if we request an anonymous instance from AutoFixture, by default we would get back an instance of the above type with it's Property containing a value similar to the one below.

Prior verion 2.4.0

However, after version 2.4.0 AutoFixture can handle requests with string length constraints through the StringLengthAttribute class by issuing a new request for a constrained string.

After verion 2.4.0

An automatically published release created from the latest successful build can be downloaded from here. The latest version is also live on NuGet.
