In a previous change, cmd/go was taught to show a "no tests ran" warning if test did nothing. But it missed a case - if no tests nor examples ran but any benchmarks were meant to be run, it would still produce the warning. This meant that running only benchmarks, which is common, would be confusing: $ go test -run='^$' -bench=. testing: warning: no tests to run BenchmarkFoo-4 300000 5056 ns/op [...] I believe this was because of a copy-paste error in the tests. This was being tested, but on the wrong file which does contain a test that was being run. Fix the path and fix the now failing test by never showing the warning if -bench was given a non-empty string. The rationale is that if -bench was given but there was no output, it's obvious that nothing happened as benchmarks always produce output even without -v. So showing a warning in those cases is redundant. To make future typos less likely, make sure that no tests are being run in the cases where we only want to run benchmarks. Fixes #17603.

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.
Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
Go is the work of hundreds of contributors. We appreciate your help!
To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html
Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
