集成测试时设置系统状态的最佳实践/想法?

对我来说,这听起来像是你想让一个基类做一些设置之类的事情,然后让你的测试类从这个基类继承,只添加新的测试功能。

Base():
  constructor():
    do your wiring
    test if everything's ok


TestClass : Base
  constructor():
    Base.constructor()
    additional setup?

  test_functions()
    ..

我们有类似的东西

public abstract class ContextSpecification
{
    [FixtureSetUp]
    public void SetUp()
    {
        EstablishContext();
        Act();
    }

    protected abstract void Act();

    protected abstract void EstablishContext();

    [FixtureTearDown]
    public void TidyUpCore()
    {
        TidyUp();
    }

    protected virtual void TidyUp()
    {

    }
}

然后,对于每组类似的测试,我们创建一个基本上下文,如下所示:

internal class TestClassTests 
{
    internal abstract class BaseContext : ContextSpecification
    {
        protected TestClass _sut;

        protected override void Act()
        {

        }

        protected override void EstablishContext()
        {
            _sut = new TestClass ();
           // common wiring
        }
    }

   internal class Given_this_situation : BaseContext
   {
       protected override void EstablishContext()
       {
           base.EstablishContext();
           // test specific wiring
       }

       protected override void Act()
       {
           // carry out the test actions
       }

       [UnitTest]
       public void ThisShouldBeTrue()
       {
          Assert.IsTrue();
       }
   }
}
