SpecFlow：ClassInitialize和的TestContext [英] SpecFlow: ClassInitialize and TestContext

问题描述

首先我是新来SpecFlow。

我有我/想用MSTest的运行作为一个功能测试涉及到自动化的特征文件完全设置服务器，数据访问...
为此我必须配置与在SpecFlow的给定块中的数据服务器，然后再启动它。我也有一些文件复制到测试的输出目录

在我所用的ClassInitialize属性来从的TestContext的TestDeploymentDir非SpecFlow功能测试;是这样的：

  [ClassInitialize] 
公共静态无效ClassSetup（的TestContext上下文）
 {
 TargetDataDeploymentRoot = context.TestDeploymentDir; 
} 
  

现在与SpecFlow我不能了，因为它由使用该属性SpecFlow本身。
一些新的属性确实存在，如 BeforeFeature 这同样的作用，但它不会对的TestContext作为参数传递。

我只需要获得访问的TestContext的TestDeploymentDir为了那里复制一些文件确实空空我的功能测试服务器之前 - 轻松可行的，而不SpecFlow但SpecFlow几乎是不可能的。

如何解决这个问题？

是否有可能呢？

非常感谢您的咨询！

< DIV CLASS =h2_lin>解决方案

为了能够访问值中的TestContext你必须为你在其中添加各种方案文件中创建部分类。

 使用Microsoft.VisualStudio.TestTools.UnitTesting; 
使用TechTalk.SpecFlow; 
 
 ///<总结> 
 ///为支撑的TestContext部分类。 
 ///< /总结> 
公共部分类DistributionFeature 
 {
 ///<总结> 
 ///测试执行上下文。 
 ///< /总结> 
私人的TestContext的TestContext; 
 
 ///<总结> 
 ///获取或设置测试执行上下文。 
 ///< /总结> 
公众的TestContext的TestContext 
 {
得到
 {
返回this.testContext; 
} 
 
组
 {
 this.testContext =价值; 
 
 //看到https://github.com/techtalk/SpecFlow/issues/96 
 this.TestInitialize（）; 
 FeatureContext.Current [的TestContext] =值; 
} 
} 
} 
  

然后，你可以访问部署利用你的脚步目录

  VAR的TestContext =（的TestContext）FeatureContext.Current [的TestContext]; 
 VAR deploymentDir = testContext.TestDeploymentDir; 
  

如果你有太多的情况下，那么你可能必须用T4自动此类文件的创建。

first of all I'm new to SpecFlow.

I have a feature file which I have / want to automate using MSTest to run as a functional test involving a fully set up server, data access ... For this purpose I have to configure the server with the data in the SpecFlow's 'Given' blocks and start it afterwards. I also have to copy some files to the test's output directory.

In the non-SpecFlow functional tests I was using the ClassInitialize attribute to get the TestDeploymentDir from the TestContext; something like this:

[ClassInitialize]
public static void ClassSetup(TestContext context)
{
  TargetDataDeploymentRoot = context.TestDeploymentDir;
}

Now with SpecFlow I can't use this attribute anymore as it is used by SpecFlow itself. Some new attributes do exist, like BeforeFeature which acts similarly BUT it doesn't pass on the TestContext as a parameter.

I just need to get access to the TestContext's TestDeploymentDir in order to copy some files there before really lauching my functional test server - easily doable without SpecFlow but almost impossible with SpecFlow.

How to deal with this issue?

Is it possible at all?

Thanks a lot for advice!

解决方案

In order to have access to values in the TestContext you have to create partial class for each scenario file you have in which you add the .

using Microsoft.VisualStudio.TestTools.UnitTesting;
using TechTalk.SpecFlow;

/// <summary>
/// Partial class for TestContext support.
/// </summary>
public partial class DistributionFeature
{
    /// <summary>
    /// Test execution context.
    /// </summary>
    private TestContext testContext;

    /// <summary>
    /// Gets or sets test execution context.
    /// </summary>
    public TestContext TestContext
    {
        get
        {
            return this.testContext;
        }

        set
        {
            this.testContext = value;

            //see https://github.com/techtalk/SpecFlow/issues/96
            this.TestInitialize();
            FeatureContext.Current["TestContext"] = value;
        }
    }
}

Then you could access the deployment directory from your steps using

var testContext = (TestContext)FeatureContext.Current["TestContext"];
var deploymentDir = testContext.TestDeploymentDir;

If you have too many scenarios, then you probably has to automate creation of such files with T4.
