it will have some effect on an object.... query for the result of the effect. If it has no visible effect its not worth unit testing!

Depends on what it's doing. If it has parameters, pass in mocks that you could ask later on if they have been called with the right set of parameters.

blocks|key|1704465|text|像往常一样:测试该方法应该做什么！|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1704466|它是否应该改变全局状态(嗯，代码味道！)什么地方？|1704467|它应该调用一个接口吗？|1704468|当使用错误的参数调用时，它是否应该抛出异常？|1704469|当使用正确的参数调用时，它应该不会抛出异常吗？|1704470|它应该...？|1704471|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|P|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|Q|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|R|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|S|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|M|$]]

As always: test what the method is supposed to do! 

Should it change global state (uuh, code smell!) somewhere? 

Should it call into an interface?

Should it throw an exception when called with the wrong parameters?

Should it throw no exception when called with the right parameters?

Should it ...?

blocks|key|1704538|text|使用Rhino+Mocks设置可能需要的调用、操作和异常。假设您可以模拟或清除方法的某些部分。如果不知道一些关于方法的细节，甚至是上下文，就很难知道。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1704539|entityMap|0|LINK|mutability|MUTABLE|url|http://ayende.com/projects/rhino-mocks.aspx^0|2|B|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Use <a href="http://ayende.com/projects/rhino-mocks.aspx" rel="nofollow noreferrer">Rhino Mocks</a> to set what calls, actions and exceptions might be expected. Assuming you can mock or stub out parts of your method. Hard to know without knowing some specifics here about the method, or even context.

blocks|key|1489521|text|试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1489522|[TestMethod]
public+void+TestSomething()

Try this:

<pre><code>[TestMethod]

{
 try
 {
 YourMethodCall();
 Assert.IsTrue(true);
 }
 catch {
 Assert.IsTrue(false);

blocks|key|1489584|text|无论您使用哪个实例来调用空方法，都可以使用Verfiy|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1489585|例如：|1489586|在我的例子中，它的_Log是instance，LogMessage是要测试的方法：|1489587|try

What ever instance you are using to call the void method , You can just use ,<code>Verfiy</code> 

For Example: 

In My case its <code>_Log</code> is the instance and <code>LogMessage</code> is the method to be tested:

<pre><code>try
{
 this._log.Verify(x =&gt; x.LogMessage(Logger.WillisLogLevel.Info, Logger.WillisLogger.Usage, "Created the Student with name as"), "Failure");
}
Catch 
{
 Assert.IsFalse(ex is Moq.MockException);
}
</code></pre>

Is the <code>Verify</code> throws an exception due to failure of the method the test would Fail ?

blocks|key|1489651|text|你甚至可以这样尝试：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1489652|[TestMethod]
public+void+ReadFiles()
{
++++try
++++{

++++++++return;+//+indicates+success

You can even try it this way:

<pre><code>[TestMethod]
public void ReadFiles()
{
 try
 {
 Read();
 return; // indicates success
 }
 catch (Exception ex)
 {
 Assert.Fail(ex.Message);
 }
}
</code></pre>

What is the best way to unit test a method that doesn't return anything? Specifically in c#.

What I am really trying to test is a method that takes a log file and parses it for specific strings. The strings are then inserted into a database. Nothing that hasn't been done before but being VERY new to TDD I am wondering if it is possible to test this or is it something that doesn't really get tested.

Unit testing void methods?

日志文件

单元测试

数据库

对不返回任何内容的方法进行单元测试的最佳方式是什么？特别是在c#中。我真正想测试的是一种方法，它获取日志文件并对其进行解析，以获得特定的字符串。然后将字符串插入到数据库中。没有什么是以前没有做过的，但作为TDD的新手，我想知道是否可以测试它，或者它是不是真正测试过的东西。
