用于单元测试的虚拟ObjectList生成器

Question

任何人都可以告知c＃中是否有任何好的框架会生成虚拟对象和列表，这样我们就不需要手动生成存根数据了？

Answer 1

You can try NBuilder . It's purpose is rapid generation of test objects.

If you have Employee class:

public class Employee
{
    public string Name { get; set; }
    public DateTime Birthday { get; set; }
} 

Generating list of 10 Employee object is simple like this:

var employees = Builder<Employee>.CreateListOfSize(10).Build();

It will generate unique incremental values for all fields of object:

Name1 7/12/2012
Name2 7/13/2012
Name3 7/14/2012
...

Also NBuilder has nice powerful fluent interface, which allows to setup custom values for any generated object:

var employees = Builder<Employee>.CreateListOfSize(10)
    .TheFirst(1).With(e => e.Name = "Sergey")
    .All().With(e => e.Address = Builder<Address>.CreateNew().Build())
    .Build();

Also you can take a look at:

• Autofixture
• AutoPoco
• Symply Test Data

Answer 2

The framework I like to use and does what you ask is the following: Rhino Mocks

This is for C#, and its superior.

Answer 3

The framework I like to use and does what you ask is the following: Unitils

but then again, I don't know for which programming language you are asking ? The one proposed is for Java.

Answer 4

If you need to create fake implementations of interfaces or abstract classes then there's a bunch of "mocking frameworks" available. One of them is Rhimo Mocks mentioned by Harry. For you as a beginner in this area I'd also suggest Moq as it's more straightforward compared to Rhino Mocks (IMHO).
