flag.PrintDefaults包含`-test`標誌

Question

我在Go中構建一個CLI應用程序。

flag.IntVar(&connections, "c", 1, "Connections to keep open per endpoint") 
flag.IntVar(&duration, "T", 10, "Exit after the specified amount of time in seconds") 
flag.IntVar(&txsRate, "r", 1000, "Txs per second to send in a connection") 
flag.BoolVar(&verbose, "v", false, "Verbose output") 

flag.Usage = func() { 
    fmt.Println(`....`) 
    fmt.Println("Flags:") 
    flag.PrintDefaults() 
} 

flag.Parse() 

if flag.NArg() == 0 { 
    flag.Usage() 
    os.Exit(1) 
} 

（Full listing on Github）

一些奇怪的原因，上面的代碼中產生：

Flags: 


-T int 
     Exit after the specified amount of time in seconds (default 10) 
    -c int 
     Connections to keep open per endpoint (default 1) 
    -r int 
     Txs per second to send in a connection (default 1000) 
    -test.bench regexp 
     run only benchmarks matching regexp 
    -test.benchmem 
     print memory allocations for benchmarks 
    -test.benchtime d 
     run each benchmark for duration d (default 1s) 
    -test.blockprofile file 
     write a goroutine blocking profile to file 
    -test.blockprofilerate rate 
     set blocking profile rate (see runtime.SetBlockProfileRate) (default 1) 
    -test.count n 
     run tests and benchmarks n times (default 1) 
    -test.coverprofile file 
     write a coverage profile to file 
    -test.cpu list 
     comma-separated list of cpu counts to run each test with 
    -test.cpuprofile file 
     write a cpu profile to file 
    -test.memprofile file 
     write a memory profile to file 
    -test.memprofilerate rate 
     set memory profiling rate (see runtime.MemProfileRate) 
    -test.mutexprofile string 
     write a mutex contention profile to the named file after execution 
    -test.mutexprofilefraction int 
     if >= 0, calls runtime.SetMutexProfileFraction() (default 1) 
    -test.outputdir dir 
     write profiles to dir 
    -test.parallel n 
     run at most n tests in parallel (default 2) 
    -test.run regexp 
     run only tests and examples matching regexp 
    -test.short 
     run smaller test suite to save time 
    -test.timeout d 
     fail test binary execution after duration d (0 means unlimited) 
    -test.trace file 
     write an execution trace to file 
    -test.v 
     verbose: print additional output 
    -v Verbose output 

任何想法，爲什麼轉到包括-test標誌？謝謝！

正如我可以看到你有一堆f代碼依賴。我發現庫github.com/tendermint/tmlibs/log對標準庫中的包testing有依賴性：searches for testing。這個標準庫有你想知道的所有標誌：testing package
