如何測試伯克利插座（BSD）API？

Question

我想測試BSP API實現的正確性和完整性。 測試集必須交叉編譯爲ARM sam7x。

Answer 1

我不知道這是否會對你有任何興趣，但是這裏有兩個鏈接來自紐約BSD大會2008的演示文稿：Detecting TCP regressions with tcpdiff（FreeBSD）和An introduction to the Automated Testing Framework (ATF) for NetBSD。兩者都很好。

Answer 2

有一個公共域名Benchmarking tool for TCP and UDP performance measurement。

它有一定量的控制可用。您可能可以使用它進行測試。
請記住，這不是測試API，而是執行性能，您將需要更多。

PCATTCP工具包括幾個選項，這些選項由程序啓動時在命令行上傳遞的參數控制。要查看可用選項，請使用「-h」選項運行PCATTCP應用程序。這裏是你會看到：

pcattcp -h 
PCAUSA Test TCP Utility V2.01.01.08 

Usage: pcattcp -t [-options] host [ < in ] 
    pcattcp -r [-options > out] 

Common options: 
-l ## length of bufs read from or written to network (default 8192) 
-u  use UDP instead of TCP 
-p ## port number to send to or listen at (default 5001) 
-s  toggle sinkmode (enabled by default) 

     sinkmode enabled: 
      -t: source (transmit) fabricated pattern 
      -r: sink (discard) all received data 
     sinkmode disabled: 
      -t: reads data to be transmitted from stdin 
      -r: writes received data to stdout 

-A  align the start of buffers to this modulus (default 16384) 
-O  start buffers at this offset from the modulus (default 0) 
-v  verbose: print more statistics 
-d  set SO_DEBUG socket option 
-b ## set socket buffer size (if supported) 
-f X format for rate: k,K = kilo{bit,byte}; m,M = mega; g,G = giga 
-c  -t: send continuously 
     -r: accept multiple connections sequentially 
-R  concurrent TCP/UDP multithreaded receiver 

。

Options specific to -t: 
-n ## number of source bufs written to network (default 2048) 
-D  don't buffer TCP writes (sets TCP_NODELAY socket option) 
-w ## milliseconds of delay before each write (default 0) 
-L ## desired transmit data rate in bytes/second 


Options specific to -r: 
-B  for -s, only output full blocks as specified by -l (for TAR) 
-T  "touch": access each byte as it's read
