c# - 使用 Xunit 运行 Specflow 但出现错误 nunit.framework

Question

我遇到了一个奇怪的问题，到处搜索，它指出了我已经做过的事情，

我有一个简单的 specflow 来测试登录，但是在浏览器打开后，我收到了这个错误。

Test Name:  Check if Login is working
Test FullName:  SpecFlow.GeneratedTests.UITest.Smoke.Features.LoginFeature.CheckIfLoginIsWorking
Test Source:    C:\**\Login.feature : line 7
Test Outcome:   Failed
Test Duration:  0:00:02,676

Result StackTrace:

Result Message: Could not load file or assembly 'nunit.framework' or one of its dependencies. The system cannot find the file specified.

我还将 app.config 文件更改为

<?xml version="1.0" encoding="utf-8"?>
<configuration>,
  <appSettings>
    <add key="xunit.diagnosticMessages" value="true"/>
  </appSettings>
  <configSections>
    <section name="specFlow" type="TechTalk.SpecFlow.Configuration.ConfigurationSectionHandler, TechTalk.SpecFlow" />
  </configSections>
  <specFlow>
    <unitTestProvider name="xUnit"/>
    <!-- For additional details on SpecFlow configuration options see http://go.specflow.org/doc-config -->
    <stepAssemblies>
      <stepAssembly assembly="SpecFlow.Assist.Dynamic" />
    </stepAssemblies>
  </specFlow>
</configuration>

奇怪的是，如果我运行正常的 Selenium 测试(不是 specflow)，它会直接运行。

这也是生成的特征文件的一部分

 using TechTalk.SpecFlow;


    [System.CodeDom.Compiler.GeneratedCodeAttribute("TechTalk.SpecFlow", "2.1.0.0")]
    [System.Runtime.CompilerServices.CompilerGeneratedAttribute()]
    public partial class LoginFeature : Xunit.IClassFixture<LoginFeature.FixtureData>, System.IDisposable
    {

        private static TechTalk.SpecFlow.ITestRunner testRunner;

#line 1 "Login.feature"
#line hidden

        public LoginFeature()
        {
            this.TestInitialize();
        }

        public static void FeatureSetup()
        {
            testRunner = TechTalk.SpecFlow.TestRunnerManager.GetTestRunner();
            TechTalk.SpecFlow.FeatureInfo featureInfo = new TechTalk.SpecFlow.FeatureInfo(new System.Globalization.CultureInfo("en-US"), "Login", "Check if Login functionality is working\r\nas expected and see if correct username " +
                    "is poping up", ProgrammingLanguage.CSharp, ((string[])(null)));
            testRunner.OnFeatureStart(featureInfo);
        }

        public static void FeatureTearDown()
        {
            testRunner.OnFeatureEnd();
            testRunner = null;
        }

        public virtual void TestInitialize()
        {
        }

        public virtual void ScenarioTearDown()
        {
            testRunner.OnScenarioEnd();
        }

        public virtual void ScenarioSetup(TechTalk.SpecFlow.ScenarioInfo scenarioInfo)
        {
            testRunner.OnScenarioStart(scenarioInfo);
        }

        public virtual void ScenarioCleanup()
        {
            testRunner.CollectScenarioErrors();
        }

        public virtual void SetFixture(LoginFeature.FixtureData fixtureData)
        {
        }

        void System.IDisposable.Dispose()
        {
            this.ScenarioTearDown();
        }

有什么我可能会遗漏的想法吗？

提前致谢。

这是正常行为，因为如果您安装 Specflow nuget 包，它将基于 nunit 安装所以你必须为specflow安装nuget xunit

Install-Package SpecFlow.xUnit -Version 2.1.0

更新如果你这样做了尝试添加 nunit 包
