.NET NUnit测试 - Assembly.GetEntryAssembly（）为null

本文介绍了.NET NUnit测试 - Assembly.GetEntryAssembly（）为null的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在使用Assembly.GetEntryAssembly类（）在单元测试运行时，Assembly.GetEntryAssembly（）为null。有一些选项如何在单元测试过程定义Assembly.GetEntryAssembly（）？

When class used Assembly.GetEntryAssembly() run in unit test, the Assembly.GetEntryAssembly() is null. Is there some option how define Assembly.GetEntryAssembly() during unit testing?

推荐答案

您可以做这样的事情与犀牛嘲笑：封装Assembly.GetEntryAssembly（）调用到一个类的接口IAssemblyLoader，注入类的都是测试。这不是测试，但沿着这个路线的东西：

You could do something like this with Rhino Mocks: Encapsulate the Assembly.GetEntryAssembly() call into a class with interface IAssemblyLoader and inject it into the class your are testing. This is not tested but something along the lines of this:

[Test] public void TestSomething() {
  // arrange
  var stubbedAssemblyLoader = MockRepository.GenerateStub<IAssemblyLoader>();
  stubbedAssemblyLoader.Stub(x => x.GetEntryAssembly()).Return(Assembly.LoadFrom("assemblyFile"));

  // act      
  var myClassUnderTest = new MyClassUnderTest(stubbedAssemblyLoader);
  var result = myClassUnderTest.MethodToTest();

  // assert
  Assert.AreEqual("expected result", result);
}

public interface IAssemblyLoader {
  Assembly GetEntryAssembly();
}
public class AssemblyLoader : IAssemblyLoader {
  public Assembly GetEntryAssembly() {
    return Assembly.GetEntryAssembly();
  }
}
