Dispatching responses from a Virtual Service

As suggested by Olga_T I created a script that dispatches responses as presented in this topic.

The idea behind it is pretty simple namely creating one operation, 4 responses and setting the dispatch style to script. The code I used is attached below:

// Get the full query string
def queryString = mockRequest.getRequest().getQueryString()
// Get the password index in the query string
def passwordIndex = queryString.indexOf("password=") + 9
// Cut out the password starting with the previously obtained index
def pass = queryString.substring(passwordIndex)
// If there are more parameters after the password rule them out
if (pass.contains("&"))
	pass = pass.substring(0, pass.indexOf("&"))

/**
 * Start dispatching responses
 */
if( !queryString.contains("grant_type=") || !queryString.contains("username=") || !queryString.contains("password=") )
{
	// Return a bad request
	return "BadRequest"
}
 else if ( !queryString.contains("grant_type=password")) 
{
	// Return an unsupported grant type response
	return "UnsupportedGrantType"	
} else if ( !queryString.contains("username=test") || !checkPasswordComplexity(pass))
{
	// Return invalid credentials
	return "InvalidCredentials"
} else 
{
	return "Success"
}

// Methods definition
def checkPasswordComplexity(String password) 
{
	if (password ==~ /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[$@$!%*?&])[A-Za-z\d$@$!%*?&]{8,}/)
		return true
	else 
		return false
}
