go test 默认执行当前目录下以xxx_test.go的测试文件。
go test -v 可以看到详细的输出信息。
go test -v xxx_test.go 指定测试单个文件，但是该文件中如果调用了其它文件中的模块会报错。
指定某个测试函数运行：
go test -v -test.run Testxxx
注意： 该测试会测试包含该函数名的所有函数，即如果待测试的函数名是TestSyncResourceQuota，那么指令go test -v -test.run TestSyncResourceQuota会测试包含该函数名的所有函数（比如下面的TestSyncResourceQuotaSpecChange、TestSyncResourceQuotaSpecHardChange等函数），详细如下：
