[翻譯]NUnit---RequiresSTA and RequiresThread Attributes(十七)

RequiresSTAAttribute (NUnit 2.5)

　　RequiresSTA特性用於測試方法、類、程序集中指定測試應該在單線程中運行。若是父測試不在單線程中運行則會建立一個新的線程。

Note：

　　在測試方法上也能夠使用STAThread特性。儘管運行時指揮在執行程序集的入口識別這個特性，可是許多用戶但願再測試上工做，因此咱們把它做爲一個同義詞。

Examples

// An STA thread will be created and used to run
// all the tests in the assembly
[assembly:RequiresSTA]

...

// TestFixture requiring a separate thread
[TestFixture, RequiresSTA]
public class FixtureRequiringSTA
{
  // An STA thread will be created and all
  // tests in the fixture will run on it
  // unless the containing assembly is
  // already running on an STA Thread
}

[TestFixture]
public class AnotherFixture
{
  [Test, RequiresSTA]
  public void TestRequiringSTA()
  {
    // A separate thread will be created for this test
    // unless the containing fixture is already running 
    // in the STA.
  }
}

RequiresThreadAttribute (NUnit 2.5)

　　RequiresThread特性指示一個測試方法、類或者程序集應該在一個獨立的線程中運行。還能夠在構造函數中指定須要的線程。

Note：這個特性常常和ApartmentState參數一塊兒使用，配合使用來建立一個新的線程。若是不合適用ApartmentState來建立線程，還還能夠使用RequiresSTA特性或者RequiresMTA特性。

Examples

// A thread will be created and used to run
// all the tests in the assembly
[assembly:RequiresThread]

...

// TestFixture requiring a separate thread
[TestFixture, RequiresThread]
public class FixtureOnThread
{
  // A separate thread will be created and all
  // tests in the fixture will run on it.
}

[TestFixture]
public class AnotherFixture
{
  [Test, RequiresThread]
  public void TestRequiringThread()
  {
    // A separate thread will be created for this test
  }
  
  [Test, RequiresThread(ApartmentState.STA)]
  public void TestRequiringSTAThread()
  {
    // A separate STA thread will be created for tnis test.
  }
}
