Question

如果我执行以下操作：

public class AIntegrationTests
{

    protected TransactionScope transaction = null;

    [SetUp]
    public void SetUp()
    {
        transaction = new TransactionScope(TransactionScopeOption.Required);
    }

    [TearDown]
    public void TearDown()
    {
        transaction.Dispose();
    }

}

[TestFixture]
public class UserRepositoryIntegrationTests : AIntegrationTests
{
    private UserRepository _sut;

    [SetUp]
    public void SetUp()
    {
        _sut = new UserRepository();

    }

    //tests
}

我收到此错误：

 network access for distributed transaction manager (msdtc) has been disabled 
Please enable Network DTC access because of qlBulkCopy.WriteToServer(DataTable table) 
for particular database

当我从父类中删除事务实例化并将其放回子类中时我没有错。

public class AIntegrationTests
{

    protected TransactionScope transaction = null;

    [SetUp]
    public void SetUp()
    {

    }

    [TearDown]
    public void TearDown()
    {
        transaction.Dispose();
    }

}

[TestFixture]
public class UserRepositoryIntegrationTests : AIntegrationTests
{
    private UserRepository _sut;

    [SetUp]
    public void SetUp()
    {
        _sut = new UserRepository();
       transaction = new TransactionScope(TransactionScopeOption.Required);
    }

    //tests
}

为什么我不允许在父类中实例化事务。如果我离开Dispose电话父母一切正常。

派生类中的

SetUp()将SetUp()隐藏在基类中，因此永远不会调用AIntegrationTests的{{1}}。明确地从SetUp()的{{1}} ...

中调用它

UserRepositoryIntegrationTests

由于您可以控制这两个类，因此您应该在基类中创建SetUp() [TestFixture] public class UserRepositoryIntegrationTests : AIntegrationTests { private UserRepository _sut; [SetUp] public void SetUp() { _sut = new UserRepository(); base.SetUp(); } //tests }并覆盖它...

SetUp()

为何EF＆amp;如果我尝试在父类中使用TransactionScope，NUnit会抛出异常吗？
