步骤定义中的 Specflow 调用步骤抛出 TechTalk.SpecFlow.SpecFlowException：步骤类的容器尚未初始化

Question

我试图从步骤定义中调用一个步骤，但是当我这样做时我得到了一个SpecFlowException。

看下面的例子：

[Binding]
public class MySteps: Steps 
{
    [Given("Doing some actions, getting (.*)  and (.*)")]
    public void DoingSomeActionsGettingValueAndOtherValue(int a, int b)
    {
        Given($"I pass first integer {a} and second integer {b}");
    }

    [Given(@"I pass first integer (.*) and second integer (.*)")]
    public void ThenIPassFirstIntegerValueAndSecondIntegerValue(int a, int b)
    {
        AreEqual(a, b);
    }
}

例外情况如下：

-> error: Container of the steps class has not been initialized!
TechTalk.SpecFlow.SpecFlowException: Container of the steps class has not been initialized!
   at TechTalk.SpecFlow.Steps.AssertInitialized()
   at TechTalk.SpecFlow.Steps.get_TestRunner()
   at TechTalk.SpecFlow.Steps.Given(String step)

谁能解释我为什么会收到这个特定的错误以及如何解决它？我在文档方面找不到太多帮助。

我试图在一个新项目中重现您的错误，但它成功了。

我的 specflow 类是从你的复制而来的：

using System;
using System.Collections.Generic;
using System.Linq;
using NUnit.Framework;
using TechTalk.SpecFlow;

namespace ClassLibrary3
{
    [Binding]
    public class MySteps : Steps
    {
        [Given("Doing some actions, getting (.*)  and (.*)")]
        public void DoingSomeActionsGettingValueAndOtherValue(int a, int b)
        {
            Given($"I pass first integer {a} and second integer {b}");
        }

        [Given(@"I pass first integer (.*) and second integer (.*)")]
        public void ThenIPassFirstIntegerValueAndSecondIntegerValue(int a, int b)
        {
            Assert.AreEqual(a, b);
        }
    }
}

这是功能文件：

Feature: SpecFlowFeature1
    In order to avoid silly mistakes
    As a math idiot
    I want to be told the sum of two numbers

@mytag
Scenario: Add two numbers
    Given Doing some actions, getting 1  and 1

我的建议是尝试在新项目中重现该错误，如果它在那里成功，则该错误一定隐藏在您未在问题中发布的代码中。
