请帮我解决这个问题。我不太明白日志中的错误是什么意思。

我今天也遇到了同样的问题，对我来说，真正的问题是在日志中进一步报告的消息不能使用threadCount参数小于1;1 > 0。
当在surefire-plugin配置中添加<threadCount>1</threadCount>时，其他错误消失。

.．.是的，为了向后兼容，我在这个测试框架中同时使用了junit和testng。
当我遇到这个错误时，这是由于我的ulimit打开文件(ulimit -n)太低。它(不知何故)被设置为仅256:
% ulimit -n
256
在我增加限制后，错误消失了:
% ulimit -n 3072
% ulimit -n
3072
您的系统可能不允许将限制设置得这么高。例如，当我试图使用更大的数字时，就会发生这种情况:
% ulimit -n 3073
ulimit: setrlimit failed: invalid argument
或者这可能低于您现有的限制，您可能面临不同的根本原因。
