cmd-tester

Much like JUnit to test process interaction.

This is a simple tool that can spawn a process and send commands to its standard input and compare response with expected.

Example:

• Given the following script as input 'src/test/test-script':

  cat src/test/test-script # This is a comment -> hello -< hello

    # This is an other commented line that will result +1 failure if fed to cat
    -> world
    -< What?
  

• Follofing command will spawn 'cat' and will send every line of script.txt that start with '->' to 'cat' input and compare that it returns string that start with '-<'

  java -jar commandTester.jar --exec "cat" --script "src/test/test-script" # Date: Thu Jun 06 01:05:44 EST 2013 # Exec: 'cat' # Script: 'src/test/test-script'

    -> hello
    -< hello
    # --------------
    # Ok
    
    -> world
    # Expected: 'What?'
    # Received: 'world'
    # --------------
    # Failed
  
    -------------
    Total: 2, Ok: 1, Failed: 1
  

How can it be used?

This tool is used for testing of text based network protocols. It is probably not the most optimal way of doing it, but it gets the job done:

> java -jar commandTester.jar --exec "netcat hostname:12345" --script "script.txt"

...will send content of script.txt to host 'hostname' to port 12345 via TCP 
and	compare response with what is expected.   

• Try following for list of supported options:

  java -jar commandTester.jar --help
