Specflow测试步骤继承会导致“模棱两可的步骤定义”。 [英] Specflow test step inheritance causes "Ambiguous step definitions"

问题描述

我想具有以下测试步骤类结构：

I want to have the following test step class structure:

[Binding]
public class BaseStep
{
    [Given(@"there is a customer")]
    public void GivenThereIsACustomer(Table table)
    {
        HandleCustomer(table);
    }

    protected virtual void HandleCustomer(Table table)
    {
    }
}

[Binding]
public class FeatureOneStep : BaseStep
{
    protected override void HandleCustomer(Table table)
    {
         // feature one action
    }

    [Given(@"feature one specific step")]
    public void GivenFeatureOneSpecificAction(Table table)
    {
        // do something
    }

}

[Binding]
public class FeatureTwoStep : BaseStep
{
    protected override void HandleCustomer(Table table)
    {
         // feature two action
    }

    [Given(@"feature two specific step")]
    public void GivenFeatureTwoSpecificAction(Table table)
    {
        // do something
    }
}

给有客户是一个常见步骤在FeatureOne和FeatureTwo中都使用了它，但是它会有不同的ha将逻辑包含在两个功能中。因此，我决定将此步骤定义放入基类中，并分别在两个派生类中重写受保护的方法。

"Given there is a customer" is a common step that is used in both FeatureOne and FeatureTwo, but it will have different handling logic inside the two features. So I decide to put this step definition into a base class and override the protected methods in two derived classes respectively.

但是，当我运行测试时，我有以下内容错误：

However, when I ran the tests, I have the following error:

TechTalk.SpecFlow.BindingException: Ambiguous step definitions found for step
'Given there is a customer': 
CustomerTestBase.GivenThereIsACustomer(Table),   
CustomerTestBase.GivenThereIsACustomer(Table)

有人可以告诉我如何解决此问题吗？

Can any one tell me how to fix this issue?

推荐答案

我自己现在已经弄清楚了，所以有几点注意（希望有人将来可以使用它）：

Just figuring this out now myself, so a couple of notes (hopefully somebody can use this in the future):

• 在基类上不要包含[Binding]属性


• 为每个功能文件创建一个派生类
  
  
  
  
  • 将[Binding]属性添加到派生类中（将自动在基本类）
  
  
  • 添加[Scope]属性te到派生类；为命名参数Feature指定功能的名称
