海洋单元测试

Question

当我尝试从Ocean SDK运行单元测试示例时，当我尝试在NUnit.exe中加载dll时，我得到一个错误。有没有人能帮我解释一下原因？

来自NUnit.exe的以下异常：

System.IO.FileNotFoundException...

Answer 1

这个案例已经通过Ocean Dev解决了。正如我们所发现的，认真遵循示例readMe文件中的所有指令是非常重要的，例如，“确保将额外的测试程序集复制到NUnit根目录”-这不仅意味着Portal根目录的DLL，也意味着lib子文件夹。有两个“不明确”点被发现: 1) nunit.exe.config中的ProbingPath必须由Petrel的ProbingPath扩展，但不能被替换；2)出于某种原因，用户可能需要将NUnit“框架”子文件夹的内容复制到Petrel根目录中。

Answer 2

可能是选中了NUnit的“启用卷影复制”选项。此选项应被关闭，以便运行测试所需的文件将被复制到Petrel根文件夹。
