Testing 使用go build,但我也看到了-test标志
我有一个Testing 使用go build,但我也看到了-test标志,testing,go,build,flags,Testing,Go,Build,Flags,我有一个main.go和mypkg/…go。我使用的是go build-o main.go或go install,其中有一些我需要的标志。但我也看到了测试标志。为什么会这样?我错过了什么 Usage of ./main: -docker string Docker API Path, defaults to local (default "unix:///var/run/docker.sock") -httptest.serve string if non
main.go

Usage of ./main:
-docker string
Docker API Path, defaults to local (default "unix:///var/run/docker.sock")
-httptest.serve string
if non-empty, httptest.NewServer serves on this address and blocks
-port int
The default port to listen (default 8000)
-test.bench string
regular expression per path component to select benchmarks to run
-test.benchmem
print memory allocations for benchmarks
-test.benchtime duration
approximate run time for each benchmark (default 1s)
-test.blockprofile string
write a goroutine blocking profile to the named file after execution
-test.blockprofilerate int
if >= 0, calls runtime.SetBlockProfileRate() (default 1)
dockerPath和port是我的标志,但正如您所看到的,其他标志不是我的标志。很可能您使用的是包的默认标志集()。请注意,您可能不是唯一使用它的人。如果导入其他包,它们也可能注册标志,这些标志将像您自己的标志(注册的标志)一样进行处理 请参见以下简单示例:
import (
"flag"
_ "testing"
)
func main() {
flag.Int("port", 80, "port to use")
flag.Parse()
}
此应用程序注册了一个端口
标志,而不注册其他标志。但它也会导入注册了很多标志的包
使用-h
命令行参数运行它,输出为:
-port int
port to use (default 80)
-test.bench string
regular expression per path component to select benchmarks to run
-test.benchmem
print memory allocations for benchmarks
-test.benchtime duration
approximate run time for each benchmark (default 1s)
-test.blockprofile string
write a goroutine blocking profile to the named file after execution
-test.blockprofilerate int
if >= 0, calls runtime.SetBlockProfileRate() (default 1)
-test.count n
run tests and benchmarks n times (default 1)
-test.coverprofile string
write a coverage profile to the named file after execution
-test.cpu string
comma-separated list of number of CPUs to use for each test
-test.cpuprofile string
write a cpu profile to the named file during execution
-test.memprofile string
write a memory profile to the named file after execution
-test.memprofilerate int
if >=0, sets runtime.MemProfileRate
-test.outputdir string
directory in which to write profiles
-test.parallel int
maximum test parallelism (default 4)
-test.run string
regular expression to select tests and examples to run
-test.short
run smaller test suite to save time
-test.timeout duration
if positive, sets an aggregate time limit for all tests
-test.trace string
write an execution trace to the named file after execution
-test.v
verbose: print additional output
exit status 2
如果您不希望您的标志与其他包的标志混合,请通过调用创建并使用您自己的标志.FlagSet
,但当然您必须使用其方法,而不是标志
