如何在VSTS中的發佈步驟上運行Visual Studio 2017 dotnet測試項目

Question

有誰知道如何使用dotnet測試在VSTS上運行測試項目嗎？

我的情況是這樣的。我有一個簡單的MVC dotnet核心Web項目，它構建並託管在一個天藍色的webapp上。在解決方案中，我有一個xUnitTest項目。

我可以在解決方案中成功構建兩個項目，並在構建階段發佈結果，準備在VSTS中進行發佈階段。我可以很好地做Webapp，但想在部署webapp之後運行測試，這是我遇到問題的地方。

試圖通過PowerShell來運行「的dotnet測試」失敗說，它不能找到其中一個Visual Studio 2017年項目沒有project.json。

當我使用「DOTNET」釋放步驟，它告訴我說的csproj是不存在的，這一點我可以從它肯定是PowerShell的看到。

我可以成功地在我的本地命令行中運行「DOTNET測試」，使用完全相同的命令，但是我需要這是在VSTS這樣我就可以使我們的CI的測試部分的基礎之上。

檢查：

1. 您可以使用託管VS 2017隊列而不是默認的託管隊列或具有1.0.0+ CLI裝
2. 確保沒有global.json文件定製機在您的項目中（或在D:\上）將CLI用於1.0.0-preview2-*版本 - 這可能是您看到project.json does not exist消息的原因。
