Nosetests

[melwin9 at gmail.com]

Initially I was shown pexpect, leaving that there, Can i make up 5 tests? I tried tests two different ways and no luck. What am I supposed to be writing up when I do a test and is there a particular way I can/should be referencing it back to its main file?

THis is what I have for the test_guess.py

from unittest import TestCase
import pexpect as pe

import guess as g
import random

random_number = random.randrange(1, 10)
correct = False

class GuessTest(TestCase):
    def setUp(self):
        self.intro = 'I have chosen a number from 1-10'
        self.request = 'Guess a number: '
        self.responseHigh = "That's too high."
        self.responseLow  = "That's too low."
        self.responseCorrect = "That's right!"
        self.goodbye = 'Goodbye and thanks for playing!'
        
    def test_main(self):
        #cannot execute main now because it will
        #require user input
        from guess import main
        
    def test_guessing_hi_low_4(self):
        # Conversation assuming number is 4
        child = pe.spawn('python guess.py')
        child.expect(self.intro,timeout=5)
        child.expect(self.request,timeout=5)
        child.sendline('5')
        child.expect(self.responseHigh,timeout=5)
        child.sendline('3')
        child.expect(self.responseLow,timeout=5)
        child.sendline('4')
        child.expect(self.responseCorrect,timeout=5)
        child.expect(self.goodbye,timeout=5)


    def __init__(self):
        self.number = random.randint(0,10)
        HIGH = 1
        LOW = 2
        OK = 3

    def guess(self, number):
        if number > self.number:
         return self.HIGH
        if number < self.number:
         return self.LOW
        return self.OK

    def test_guesstoolow(self):
        while not correct:
            guess = input("What could it be?")
            if guess == random_number:
                print "Congrats You Got It"
                correct = True
            elif guess > random_number:
                print "To High"
            elif guess < random_number:
                print "To Low"
            else:
                print "Try Again"


and the guess.py file is


intro = 'I have chosen a number from 1-10'
request = 'Guess a number: '
responseHigh = "That's too high."
responseLow  = "That's too low."
responseCorrect = "That's right!"
goodbye = 'Goodbye and thanks for playing!'

def main():
    print(intro)
    user_input = raw_input(request)
    print(responseHigh)
    print(request)
    user_input = raw_input(request)
    print(responseLow)
    user_input = raw_input(request)
    print(responseCorrect)
    print(goodbye)

if __name__ == '__main__':
    main()
