NUnit Extension小介绍

  NUnit是我们经常使用的测试框架，既然常用，肯定会有人难不住寂寞给TA加上一些自己认为酷的功能上去，也就是扩展，那下面我们就看看到底有几种扩展。

---

Extension类型

 

Add In

嵌入NUnit内部，改变TA的行为，通常提供一种全新的测试方式，比方说FireBenchmarkers就给NUit加上了性能测试。

 

Add On

在Unit上方或者外部，不像Add In一样修改NUint的行为，通常他们都用来测试一种特殊的应用，或者实现一种新的测试书写风格

 

Runners

提供另外一种方式运行NUnit

 

Extras

除了上面三种之外的，典型的例子是加test report

  上面的表格中列出了NUnit官方给出的扩展工具，我比较关心的是能让我体面的写出测试的扩展。

 

NUnit Extension Method

 

var actual =2.5;
actual.Should(Be.EqualTo(2.5).Within(0.5));

　　个人感觉不是很好，例子里面层层嵌套，很不习惯，我更倾向于actual.shouldBe(2.5).Within(0.5)

 

Njasmine

  
一种我看不懂的测试写法，作者说是rspec风格，我怎么看着不像。。。从名字上面看，和jasmine有着千丝万缕的联系

 

NUnitex

很强大的一种测试方法扩展，支持NUnit，XUnit，MSTest，这下大家满意了吧。。。

文章作者说：Charlie Poole, NUnit’s project leader, included NUnitEx as official NUnit AddOns “under review for possible inclusion in NUnit 3.0” (thanks Charlie) and we are looking for some response from users (the thread is here).也就是说TA是被NUnit组织推荐的

真实性我就很难验证了。

一些典型的验证方法：

 

actual.Should().Be.True();
actual.Should().Be.EqualTo(something);actual.Should().Be.InstanceOf<SomeClass>();

var something =newobject();
something.Should()
    .Not.Be.Null()
    .And
　　 .Not.Be.EqualTo(newobject());

minvalue.Should().Be.LessThanOrEqualTo(minvalue +1);

actual.Should().Be.SubsetOf(new[]{1,2,3,4}); 

我认为最牛逼的就是TA居然支持LinQ形式的验证

 

new[]{1,2}.Should().Satisfy(x => x.SequenceEqual(new[]{1,2}));

 

  

这难道不酷么？
