Pexpect

[Iranna Mathapati]

Hi Team,



The fallowing script(function) is working if its in PDB mode(trace line by
line) but same script is not working if its remove/comment PDB and run one
shot.



log.info("Time out expection")

            uut_con1 = pexpect.spawn('telnet %s'%power_ip)

            uut_con1.logfile = sys.stdout

            uut_con1.delaybeforesend = None

            time.sleep(30)

            uut_con1.send("%s\r" % username)

            uut_con1.expect([r"Password:"],timeout=30)

            uut_con1.send("%s\r" % pass_word)

            time.sleep(30)

            uut_con1.send("\r")

            uut_con1.expect([r'#?'],timeout=30)

            uut_con1.send("power outlets %d off\r"%outlet)

            uut_con1.expect([r'wish to turn outlet'],timeout=30)

            uut_con1.send("y\r")

            uut_con1.send("\r")

            uut_con1.expect([r'#?'],timeout=30)

            uut_con1.send("power outlets %d on\r"%outlet)

            uut_con1.expect([r'wish to turn outlet'],timeout=30)

            uut_con1.send("y\r")

            uut_con1.send("\r")

            uut_con1.expect([r'#?'],timeout=30)

            uut_con1.close()

            uut_con.close()

            time.sleep(300)


check_prompt(self,username,pass_word,dev_ip,dev_port,power_ip,outlet)
