我的测试都在昨天进行，但今天它们都失败了。我尝试制作一个新的测试类，只是运行一个空测试，但也失败了。我不知道发生了什么。这是堆栈跟踪：

有谁知道为什么我的测试可能会失败？测试类的内容只是一个空文件，带有测试方法存根。当然你不需要在这里看到一个空的方法存根？您可以通过转到Unity来复制完全相同的文件 - ＆gt;新的编辑模式脚本，然后不修改生成的文件。我的项目构建正常，测试在调试模式下运行。有什么想法吗？
更新
如果我使用Unity创建测试脚本并使用monodevelop运行它们，它们可以正常工作。我使用的是Unity Collaborate。他们没有与Rider或Visual Studio一起运行。也许是因为Unity Collaborate不能与除了Monodevelop之外的IDE一起使用？我必须设置某种项目设置吗？
