How to run all Golang benchmark tests including subfolders
问题
我有一个Go应用程序，其中包含一些单元测试和基准测试，分别位于根目录和名为"message"的子文件夹中。
我使用以下命令来运行根目录中的所有单元测试，包括"message"和其他子文件夹中的测试：
go test ./...
我希望能够对基准测试做同样的操作，即运行所有基准测试。以下命令可以运行根目录中的基准测试：
go test -bench .
但是，位于"/message"文件夹中的基准测试被忽略了，这是预期的。所以我尝试从根目录运行以下命令：
go test -bench ./...
但是，这个命令完全没有被识别，Go似乎执行的是位于根目录中的单元测试。我甚至尝试在命令中指定"message"文件夹，如下所示：
go test -bench ./message
...但是也失败了。目前，如果我想运行"message"文件夹中的基准测试，我必须进入该文件夹并执行以下命令：
go test -bench .
那么正确的方法是什么呢？如何告诉Go在根目录和子文件夹中查找基准测试？在"-bench"标志的正则表达式参数中如何工作？显然，它与单元测试运行器的正则表达式不同。
英文:
I have a Go application with a number of unit and benchmark tests both in the root and in a subfolder called "message".
I execute the following command to run all unit tests from the root including the ones in the messages and any other subfolder:
go test ./...
I want to achieve the same for the benchmark tests, i.e. run them all. The following works for the ones in the root directory:
go test -bench .
The benchmark tests in the /messages folder are ignored which is expected. So I run the following from the root:
go test -bench ./...
That's not recognised at all, Go seems to execute the unit tests that are located in the root dir. I even tried to specify the message folder in the command as follows:
go test -bench ./message
...but it also failed. Currently if I want to run the benchmark tests in the message folder I have to cd into that folder and execute
go test -bench .
like above.
So what's the correct way then? How can I tell Go to find the benchmark tests both in the root and the subfolders? How does the regexp arg work in the case of the -bench flag? Apparently it's different from the regexp for the unit test runner.

你应该使用./...来对当前工作目录及其所有子目录中的所有文件进行基准测试。如果你希望获得更详细的输出，可以使用-v标志。此外，使用-benchmem可以列出内存分配情况。
go test -v ./... -bench=. -run=xxx -benchmem
英文:
You should use ./... to bench all the files from the current working directory and all of its subdirectories. If you wish to get a more verbose output you can use the -v flag. Also it's good to list the memory allocation by using -benchmem.
go test -v ./... -bench=. -run=xxx -benchmem

-bench标志接受正则表达式，因此要在所有包中运行所有基准测试（-bench .），可以使用以下命令：go test -bench=. ./...
英文:
-bench flag takes regex so to run all benchmarks (-bench .) in all packages: go test -bench=. ./...
