我正在运行连接到我们的暂存环境 Scylladb 集群之一的 Golang 集成测试。当我运行go test ./...它实际上并行运行 2 个包（来自我调用的根目录的子目录go test ./...）。在这些包中的每一个中，都有一个主_test.go文件通过一组测试运行。
当我分别运行这些软件包时，工作完美。所有测试都通过，没有超时等。但是，当我一起运行它们时，我在两者中都得到了失败的测试（每个包都有 1 个失败的测试），并且偶尔会使用 goroutine 打印出堆栈跟踪，如下所示：

如堆栈跟踪所示，许多错误来自gocql. 我目前为每个测试包创建一个新会话（也单独关闭）：https ://github.com/gocql/gocql/blob/master/session.go#L112
运行 go 测试时有多个会话是不是很糟糕？当这两个会话都打开时，似乎只有这些问题。任何帮助，将不胜感激！
