如何在运行时获取TestPropertyAttribute的值 [英] How to get the value of TestPropertyAttribute in runtime

问题描述

我正在使用带有MS测试的SpecFlow来自动化BDD测试用例。当我们使用Scenaio-Outline和示例时，MS测试使用variant inbuild构建场景名称。我想在运行时调用该变体名称以进行报告。有人可以在这里帮助
。

I am using SpecFlow with MS test for automating BDD test cases. When we are using Scenaio-Outline with examples, the MS test consturcting the scenario name with variant inbuild. I want to call that variant name during runtime for reporting purpose. Can someone please help here.

我想读取"VariantName"的值。在运行时。

I want to read the value of "VariantName" at run time.

[Microsoft.VisualStudio.TestTools.UnitTesting.TestPropertyAttribute（" VariantName"，" 1"）]

详细信息：

我有一个Scenario大纲像下面

I have a Scenario outline like below

Feature: Test Reporting
    Scenario Outline:  Verify pushing data to Event hub using API concept
       Given User Insert Geo Infomation to LoadCollection '<ScenarioId>'

Examples:
| ScenarioId | 
| Scenario_00 | 
| Scenario_01 |
| Scenario_02 | 

在testExplorer中（我正在使用MSTest）我看到如下情况

In testExplorer(I am using MSTest) i am seeing the scenarios like below

TestReportingFeature
-->VerifyPushingDataToEventHubUsingAPIConcept_Scenario_00
-->VerifyPushingDataToEventHubUsingAPIConcept_Scenario_01
-->VerifyPushingDataToEventHubUsingAPIConcept_Scenario_02

我编码如下获取测试名称

I Coded like below to get the test name

var title = ScenarioContext.Current.ScenarioInfo.Title;

以上代码返回类似  VerifyPushingDataToEventHubUsingAPIConcept    Scenario_00  是
没有附加。

above code returning like VerifyPushingDataToEventHubUsingAPIConcept the Scenario_00 are not getting appended.

我期待  VerifyPushingDataToEventHubUsingAPIConcept_Scenario_00  要退回，
请帮我解决问题。

I am expecting VerifyPushingDataToEventHubUsingAPIConcept_Scenario_00 to be returned, Please help me how to get it.

嗨朋友，

欢迎来到MSDN论坛。

>>我想在运行时读取"VariantName"的值。[Microsoft.VisualStudio.TestTools.UnitTesting.TestPropertyAttribute（" VariantName"，" 1"）]

>> I want to read the value of "VariantName" at run time. [Microsoft.VisualStudio.TestTools.UnitTesting.TestPropertyAttribute("VariantName", "1")]

为此，您可以使用GetCustomAttributes方法获取值。示例代码如下：

For this, you can use GetCustomAttributes method to get the value. Sample code are as below:

[TestClass]
    public class UnitTest1
    {
        [TestProperty("VariantName", "1")]
        [TestMethod]
        public void MyTestMethod()
        {
            var myAttribute = GetType().GetMethod("MyTestMethod").GetCustomAttributes(true).OfType<TestPropertyAttribute>().FirstOrDefault(); //get the instance of TestPropertyAttribute of "MyTestMethod"
            Console.WriteLine(myAttribute.Name);  //output the name:VariantName
            Console.WriteLine(myAttribute.Value); //output the value:1
        }
    }

注意：此方法是获取TestProperty的实例，因此我们可以使用它来获取名称和相应的值在一起。

Note: This method is to get the instance of TestProperty, so we can use it to get name and corresponding value together.

此外：您可以从
此问题 关于获取C＃中的属性。

In addition: You can get more info from this issue about get attribute in C#.

关于specflow的详细方案，似乎第三方扩展，我不熟悉它。很抱歉给您带来不便。

And as for the detailed scenario about specflow, it's seems a third-party extension and I'm not familiar with it. Sorry for this inconvenience.

希望以上所有内容都有所帮助，如果有任何更新，请随时在此分享。

Hope all above can help, if there has any update, feel free to share here.

最好的问候
