GO ： go test -v 测试错误：panic: test timed out after 10m0s 。。。exit status 2

go test -v 测试时可能会遇到的错误“：

panic: test timed out after 10m0s

这导致了：我在测试用例中使用websocket发收数据时遇到的新的问题：

err write tcp IP1:9001->IP2:56240: write: broken pipe

Broken pipe产生的原因通常是当管道读端没有在读，而管道的写端继续有线程在写，就会造成管道中断。（由于管道是单向通信的） SIGSEGV(Segment fault)意味着指针所对应的地址是无效地址，没有物理内存对应该地址。

go test -v 详细错误信息如下：

解决方案： go test -timeout duration

timeout 的默认 值：duration=10m

 把duration设置为大于你测试用例所需的时间就行行了.
