config.js

/*
This file contains configs for the NodeFuzz. 

config.init() function can be used to load set specific configurations. 
You can also add commandline-flags or platform specific configs like demonstrated below.

*/

/*
Required:

bufferSize: 			Used by nodefuzz.js. Defines how many previous testcases will be hold in previousTestCasesBuffer.
defaultModuleDirectory: Used by moduleLoader.js. Defines default location where fuzzer-modules are loaded
						when -mp commandline argument is not used.
port: 					Used by nodefuzz.js. Defines port for HTTP-server.
timeout: 				Used by nodefuzz.js. Defines timeout after testcase request when client is considered not responding.
testCasesWithoutRestart:Used by nodefuzz.js. Defines how many testcases are sent in a row before actions are needed.			
clientFile: 			Used by nodefuzz.js. Holds a string that is sent to client software when it connects to HTTP-server.			 
*/

/*
Optional:
previousTestCasesBuffer: 	Used by nodefuzz.js. Holds n previous testcases sent to client. n is defined by config.bufferSize. 
							You can save crash reproducing file from this buffer. See instrumentation-module for example.
							(Note: This variable is now defined in nodefuzz.js)
disableDefaultWsOnRequest: 	Boolean to enable/disable the default WebSocket.on('request') handler.
addCustomWebSocketHandler: 	Function that is executed if available on init. Get WebSocket server object as parameter.
httpRootDir: 				Root directory for the HTTP-server. (Note: Really poor implementation that did the trick in one of my experiments.) 
disableTestCaseBuffer: 		Boolean to enable/disable test case buffer. More info on changelog
*/

/*
Used in demo-stuff:

fuzzfile: 				Default client-file to be used as base for reBuildClientFile
reBuildClientFile: 		Used when selected module needs alterations to client-file.
result_dir: 			Used by instrumentations: Directory where instrumentations save logs and repro-files.
