using expect to test as text-based menu
in [TCL]
|
From: Reagan on 15 Mar 2010 13:25 Hi there, I am fairly new to expect. I have been using it to automate some testing and have recently run into an issue that I cannot figure out. I have a text based menu system which is navigable via arrow keys ... I can log into the system and see the menu however, I cannot figure out how to send commands to the menu in expect mode. ======================================== My environment is as follows: expect 5.43.0 on Ubuntu 2.6.24-24 with tcl 8.4 ======================================== My menu looks like this: Disconnect Calibrate > Utilities > Configuration > Parameters > Processing > System Passwords > Diagnostics > About Save Changes I have an expect script that can ssh into this system and "expect" the above menu. However, I cannot send it any control characters for example, the down arrow or "\033\[B". Here is the script that I am currently working with: #!/usr/bin/expect -f set env(TERM) vt100 set password 123abc set ipaddr 172.18.123.200 set timeout -1 match_max -d 100000 spawn ssh -Y root@$ipaddr expect "*?assword:*" send -- "$password\r" sleep .5 expect "Disconnect Calibrate > Utilities > Configuration > Parameters > Processing > System Passwords > Diagnostics > About Save Changes\r" # trying to send return followed by "y" and return which should simply disconnect from the client send -- "\ry\r" # down arrow arrow #send -- "\033\[B" # up arrow #send -- "\033\[A" # back arrow #send -- "\033\[D" Note if I take out the expect "Disconnect ... statement above and put in an interact statement like the one that follows I can get this to work. I.e., with the below code when I hit a CRTL-A a return y return will be sent to my process and it will disconnect. set CTRLZ \032 set CTRLC \003 set CTRLA \001 interact { -reset $CTRLZ {exec kill -STOP [pid]} $CTRLA { exp_send "menucmd...\ry\r" } ~~ } My stumbling block is, how do I get this to work with out interact mode i.e., I want this all scripted / automated. thanks in advance for any suggestion / assistance! -reagan
From: Glenn Jackman on 16 Mar 2010 14:23 Not an answer specifically to your question, but while you're developing, add: exp_internal 1 after your spawn command. That will allow you to see what expect sees, and you can diagnose your expect misses. At 2010-03-15 01:25PM, "Reagan" wrote: > Hi there, > > I am fairly new to expect.
