Question

我常常有一些必须成对出现的功能，例如

//Example
startSomething()
...
stopSomething()

//Example
openSomething()
...
closeSomething()

虽然单元测试startSomething()和openSomething()很容易，因为它们不需要先前的条件/设置，我应该如何对需要事先调用的对应单元进行单元测试？

大多数单元测试框架都有设置测试，这些测试在测试用例之前/之后和/或每个测试用例中调用。以NUnit为例：

[TestFixture]
public class MyTest
{
    [OneTimeSetup]
    public void GeneralSetup()
    { ... }  //Called before starts all test cases

    [OneTimeTearDown]
    public void GeneralTearDown()
    { ... } //Called after all test cases are finished

    [Setup]
    public void Setup()
    { ... }  //Called before each test case

    [TearDown]
    public void TearDown()
    { ... } //Called after each test case

    [Test]
    public void Test1()
    { ... }

    [Test]
    public void Test2()
    { ... }
}

如何单元测试必须成对出现的功能？
