NBuilder 是一个开源项目，通过流畅且可扩展的接口，允许开发者迅速生成测试数据，自动为内置 .NET 数据类型（如 int 和 string）的属性和公共字段赋值。它还支持通过 lambda 表达式自定义感兴趣的属性。本文提供了三个实例来展示如何使用 NBuilder，包括设置标题、描述、价格等，并展示了如何通过构造函数和 lambda 表达式生成不同类型的测试数据。
What is it?
Through a fluent, extensible interface, NBuilder allows you to rapidly create test data, automatically assigning values to properties and public fields that are of type of the built in .NET data types (e.g. ints and strings). NBuilder allows you to override for properties you are interested in using lambda expressions.
NBuilder is an open source project, hosted on google code
Some quick examples

var products = Builder<Product>.CreateListOfSize(10)
.TheFirst(2)
.With(x => x.Title =
"special title"
)
.Build();

Would give you something like this:

var products = Builder<Product>.CreateListOfSize(10)
.All()
.WithConstructor(() =>
new
Product(
"my title"
))
.Random(5)
.WithConstructor(() =>
new
Product(
"my other title"
))
.And(x => x.Created = August.The17th.At(09, 00))
.Build();
