In my Go package there are several benchmark files like map1_benchmark_test.go and map2_benchmark_test.go. In every *_benchmark_test.go file, there is more than one benchmark function like func BenchmarkMapTravel(b *testing.B) and func BenchmarkMapGet(b *testing.B).
Question is, how can I test just one benchmark function?
I attempted to read some manuals, and got nothing about benchmark by running go help test.

Running a benchmark in Go To run a benchmark in Go, we'll append the -bench flag to the go test command. The argument to -bench is a regular expression that specifies which benchmarks should be run, which is helpful when you want to run a subset of your benchmark functions.
Benchmark Testing is a set of standards, metrics, or a reference point, against which, the performance quality of a product or a service is assessed or evaluated.
Description of testing flags
-test.bench pattern Run benchmarks matching the regular expression. By default, no benchmarks run. -test.run pattern Run only those tests and examples matching the regular expression.For convenience, each of these
-test.Xflags of the test binary is also available as the flag-Xin 'go test' itself.
For help,
$ go help testflag For example,
go test -test.bench MapTravel go test -test.bench MapGet or
go test -bench MapTravel go test -bench MapGet To bypass test functions, include a -test.run pattern that filters out every single test. For example,
go test -test.bench MapTravel -test.run=thisexpressionwontmatchanytest or
go test -bench MapTravel -run=^$ If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
