在为我得到的测试项目执行蛋糕脚本时，

    An error occurred when executing task 'test'.
    Error: System.Exception: DotCover: Process returned an error (exit code -3).

       at Cake.Program.Main()

我怎么解决这个问题？

Return code -3fromdotcover.exe表示正在分析的应用程序中的退出代码不等于0. （简单的英语，你的单元测试失败了）。请参阅此链接。

要验证测试是否失败，请尝试在没有 DotCover 别名的情况下单独运行单元测试。

即使测试失败也要继续，请参阅Cake 中的错误处理

Cake 只是从底层工具（在本例中为 DotCover）返回退出代码。如果你在诊断模式下运行 Cake：

如何为 Cake 启用诊断详细信息

您应该能够获取正在执行的确切 DotCover 命令，然后您可以在命令行中手动运行它。此时，输出可能再次为 -3。

我要说的是，这很可能是 DotCover 分析您的应用程序的问题，而不是 Cake 的问题。
