调试NUnit的测试在Visual Studio C＃2010速成 [英] Debugging Nunit tests in Visual Studio C# Express 2010

问题描述

我已经遵循了这一建议得到的调试NUnit的测试工作。

的 http://www.blackwasp.co.uk/NUnitCSharpExpress.aspx

不过，我有几个测试，做 Assert.Throws< ...> ，这将导致调试器打破时，我测试了发生异常的时候，确实我想如果发生这些呼叫之外的例外，它打破

我怎样才能调试器忽略这些种方法内引起的异常？

---

编辑：！我已经试过事件下面，它不工作

  [测试] 
公共无效InstanciatingWithNullParameterThrowsException（）
 {
试
 {
 Assert.Throws< ArgumentNullException>（（）=>新建CachedStreamingEnumerable< INT>（空） ）; 
 //这仍然抛出和止损是能够经过这一个
称为} 
抓
 {
 
} 
}调试测试
  

解决方案

下面是我在Visual Studio什么工作（虽然专业的，不会表达，但我想这不应该的问题）。

• 弹出例外对话框通过Ninjapig的建议




• 点击添加... 按钮，打开新建例外对话框。



• 在下拉框中


• 在编辑框中选择公共语言运行库异常中输入NUnit.Framework.AssertionException


• 点击确定关闭新建例外对话框。


• 早在例外对话框中确保两个复选框（时抛出的和的用户未处理）是的选中的

现在，调试器应该完全忽略一个NUnit的断言失败（即抛出，捕获与否， NUnit.Framework.AssertionException ）。

更新：这只能从打破进入调试器阻止，也不能忽视例外本身;即，它不会改变实际的程序流程。 APPART更改或替换或封装中的try-catch块断言通话，我不认为这有什么，可以做到这一点（至少不是自动）。

I've followed this advice to get debugging working for NUnit tests.

http://www.blackwasp.co.uk/NUnitCSharpExpress.aspx

However, i have several tests that do Assert.Throws<...>, which causes the debugger to break when the exception i'm testing for occurs, when really i want it to break if an exception occurs outside of those calls.

How can i get the debugger to ignore exceptions caused from within these kinds of methods?

EDIT: I've event tried the below, which doesn't work!

[Test]
public void InstanciatingWithNullParameterThrowsException()
{
    try
    {
        Assert.Throws<ArgumentNullException>(() => new CachedStreamingEnumerable<int>(null));
        // This still throws and stops be being able to debug tests called after this one
    }
    catch
    {

    }
}

解决方案

Here is what worked for me (although in Visual Studio Professional, not Express, but I guess that should not matter).

• Bring up the "Exceptions" Dialog as suggested by Ninjapig.

• Click on the Add... Button, to open the "New Exception" dialog.

• Select "Common Language Runtime Exceptions" in the drop down box
• In the Edit box enter "NUnit.Framework.AssertionException".
• Click OK to close the "New Exception" dialog.
• Back in the "Exceptions" dialog make sure that both checkboxes (Thrown and User-unhandled) are unchecked.

Now, the debugger should completely ignore a NUnit assertion failure (i.e. a thrown, caught or not, NUnit.Framework.AssertionException).

UPDATE: This will only prevent from breaking into the debugger, it cannot ignore the exception itself; i.e. it will not alter the actual program flow. Appart from changing or replacing or encapsulating the Assert-calls in try-catch blocks, I don't think there is anything that can achieve that (at least not automatically).
