将MSpec测试转换为普通NUnit

Question

我正在尝试开始使用纯TDD并考虑BDD风格.我试图掌握,与MSpec相比,写作单元测试的感觉与NUnit完全不同.

考虑一个简单的MSpec测试,如下所示:

[Subject("PersonRepository")]
class when_adding_a_new_person
{
     Establish context = () => sut = new PersonRepository();

     Because of = () => sut.AddPerson("Jim", "Panse");

     It should_have_a_person = sut.Count.ShouldEqual(1);
     It should_have_that_persion = sut.Contains("Jim", "Panse");

     static PersonRepository;
} 

你如何以干净的方式将其转换为NUnit,但不使用任何BDD扩展或任何东西.我认为每个应该断言是一个可单独运行的测试Establish并且 Because应该只对所有断言执行一次是个好主意.我可以使用[Setup]的Establish和 Because,但会为每个测试运行.我可以用Assert.的It,但是这不会让他们单独运行的测试.

这个例子与NUnit风格相比如何？

I generally would recommend against converting from MSpec to NUnit. When introducing people to MSpec I like to start with a "classic" NUnit (PersonRepositoryTester.TestAddNewPerson) fixture, convert it over to a more BDDish fixture like the one below and then show them how MSpec can help to reduce language noise and introduce readability + better reporting.

[TestFixture]
public class When_adding_a_new_person
{
    PersonRepository sut;

    [TestFixtureSetUp]
    public void Establish_and_because()
    {
        sut = new PersonRepository();

        sut.AddPerson("Jim", "Panse");  
    }

    [Test]
    public void It_should_have_one_person()
    {
        Assert.That(sut.Count, Is.EqualTo(1));
    }

    [Test]
    public void It_should_contain_the_new_person()
    {
        Assert.That(sut.Contains("Jim", "Panse"), Is.True);
    }
}
