Question

执行我正在获得的测试项目的蛋糕脚本时，

    An error occurred when executing task 'test'.
    Error: System.Exception: DotCover: Process returned an error (exit code -3).
       at Submission#0.<.ctor>b__29(Exception exception)
       at Cake.Core.DefaultExecutionStrategy.HandleErrors(Action`1 action, Exception exception)
       at Cake.Core.CakeEngine.HandleErrors(IExecutionStrategy strategy, Action`1 errorHandler, Exception exception)

       at Cake.CakeApplication.Run(CakeOptions options)
       at Cake.Program.Main()

我该如何解决这个问题？

Answer 1

-3返回代码dotcover.exe表示正在分析的应用中的退出代码不等于0。（简单的英语，您的单元测试失败）。请参阅此link。

要验证测试是否失败，请尝试单独运行单元测试而不使用DotCover别名。

要继续测试失败，请参阅Cake中的error handling

Answer 2

Cake只返回底层工具的退出代码，在本例中为DotCover。如果在诊断模式下运行Cake：

How to enable diagnostic verbosity for Cake

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手动运行它。此时，输出可能会再次为-3。

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

进程在蛋糕执行中返回错误（退出代码-3）
