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()
