在C#中测试Environment.Exit() [英] Test Environment.Exit() in C#

问题描述

C#中是否存在Java中 ExpectedSystemExit 的某种等效形式?我的代码中有一个出口，非常希望能够对其进行测试.我在C#中发现的唯一问题是变通办法.

Is there in C# some kind of equivalent of ExpectedSystemExit in Java? I have an exit in my code and would really like to be able to test it. The only thing I found in C# is a not really nice workaround.

示例代码

public void CheckRights()
{
    if(!service.UserHasRights())
    {
         Environment.Exit(1);
    }
}

测试代码

[TestMethod]
public void TestCheckRightsWithoutRights()
{
    MyService service = ...
    service.UserHasRights().Returns(false);

    ???
}

我正在使用VS框架进行测试(+ NSubstitute进行模拟)，但是切换到nunit或进行此测试的任何问题都不是问题.

I am using the VS framework for testing (+ NSubstitute for mocking) but it is not a problem to switch to nunit or whatever for this test.

推荐答案

我最终创建了一个新方法，然后可以在测试中进行模拟.

I ended up creating a new method which I can then mock in my tests.

代码

public void CheckRights()
{
    if(!service.UserHasRights())
    {
         Environment.Exit(1);
    }
}

internal virtual void Exit() 
{
    Environment.Exit(1);
}

单元测试

[TestMethod]
public void TestCheckRightsWithoutRights()
{
    MyService service = ...
    service.When(svc => svc.Exit()).DoNotCallBase();
    ...
    service.CheckRights();
    service.Received(1).Exit();
}
