我开始使用SpecFlow来测试我的Azure Data Factory管道。我使用 VS 2019 & .NET Framework 4.7.2。当我尝试运行我的测试时，它开始执行，然后瞬间完成。我还观察到，它没有击中断点，我在 feature file 以及在 binding. 这是我的 packages.config 文件。

当我检查我的日志文件时，我可以在生成的日志文件中找到这一行。No tests executed (activation needed). 谁能告诉我，我这是哪里出了问题？请注意，我的解决方案是正常构建的。
PFB整个日志，供大家参考。

当我更新我的SpecFlow NuGet包时，我也出现了同样的问题。 SpecFlow现在需要你通过微软账户设置一个账户。
在Visual Studio中检查测试的输出，应该有一个激活账户的链接。 请看这里的文档。https:/specflow.org2020introducing-the-specflow-account.
