NUnit-console 2.6.3 有时会打印出以下错误消息，而不是运行测试。以下是我的 Jenkins 测试构建日志的摘录：

它随机发生。我不会更改测试程序集或 NUnit 配置。我通过 NCover 运行 NUnit，但是当我从命令行单独使用 NUnit 时，同样的问题会重复。

在 NUnit 中启用详细日志记录后，我注意到 nunit-agent 进程在 nunit-console 运行半分钟后将其第一条消息打印到日志中。我从源代码中发现，nunit-console 等待 30 秒，让生成的 nunit-agent 进程自行注册。显然，有些东西会延迟加载 nunit-agent，因此在 nunit-console 中会遇到超时，从而导致“无法定位夹具”。之后 nunit-agent 进程仍在运行，我必须手动将其杀死。

任何 NUnit 专家都可以帮助我吗？

Charlie 在该 Google Groups 线程中建议的潜在解决方法：

避免这种情况的一种方法是停止使用代理。将配置文件 (nunit-console-x86.exe.config) 更改为在 2.0 CLR 之前使用 4.0 CLR。然后测试将在同一进程中运行，并且不会创建代理。

我已经确认<supportedRuntime version="v4.0.30319" />在<startup>nunit-console.exe.config 文件（或 nunit-console-x86.exe.config）中添加并删除<supportedRuntime version="v2.0.50727"（如果存在）确实会导致我的测试在不产生 nunit-agent.exe 进程的情况下运行. 在我的情况下，我还没有确认这是否修复了“无法找到夹具”的错误，但 OP (krzysiek_w) 确实在同一个线程中确认了它：

我不知道在没有 nunit-agent 的情况下在 nunit-console 中运行测试的可能性。在 nunit-console 配置文件中设置支持的框架后，测试执行而不创建完全解决问题的单独进程。

作为附加说明，/trace=Verbose可以将该选项传递给 NUnit 以获取更多信息，就像 krzysiek_w 在该线程中所做的那样。对我来说，这些日志输出到C:\Users\(myuser)\AppData\Local\NUnit\logs.
