配有Nunit 3控制台转轮的Specflow测试

Question

我最近开始一个新项目，并决定使用Specflow 2.1 它附带NUnit3。

目前该项目的设置和Visual Studio中的测试运行器正确执行，但是当我尝试从Nunit 3控制台运行器运行相同的测试时出现错误。

我使用的命令是 nunit3-console.exe --labels=All --framework=net-4.5 Blah.Testing.Specflow.dll

我添加了两个天然NUnit的测试用相同的组件，而这些都是执行细，其是失败

我试图反映一个specflow测试TechTalk.Specflow Assembly去查看CreateTestRunnerInstance方法，但是没有找到任何有用的指导我的解决方案。

任何帮助，将不胜感激

Answer 1

看起来，你有SpecFlow +亚军（SpecRun）插件还配置。

在TechTalk.SpecRun.SpecFlowPlugin .Runtime.SpecRunTestRunnerManager.CreateTestRunnerInstance（c）中：\ TeamCity的\ BuildAgent \工作\ 245a3e4d646c0875 \ SpecFlowPlugins \ TechTalk.SpecRun.SpecFlowPlugin.2-0-0 \运行\ SpecRunTestRunnerManager。 cs：第33行

请检查app.config中的插件和unittestprovider设置。 之后，重新生成所有功能代码隐藏文件（简单保存功能文件）。
