为什么要使用ClassCleanup？

Question

Currently I'm testing out the Unit Test features of .NET Framework and therefore came across [TestInitialize] [TestCleanup] [ClassInitialize] and [ClassCleanup] . Why should I use [ClassCleanup] because I cannot come up with any scenarios where I could use [ClassCleanup] in a useful way.

I think it might be similar to [TestCleanup] which cleans up after every [TestMethod] but [ClassCleanup] is called after running through all tests and not each one (as explained to me). This is the reason why I don't know how to use it or whether to use it at all (right now I'm not using it at all).

Fell free to explain this to me and thanks in advance! :)

You might want to use it to cleanup the resources that you created in ClassInitialize . Imagine you want to spin a database for your test class that all test methods should be able to use. You create it in ClassInitialize and destroy in ClassCleanup .
