Vim: Test driven configuring with DejaGnu

Problem

Configuring Vim should be test driven. How else can I make sure all configuration settings remain in effect?

I'm going to use Tcl and Expect. First attempt with interactive expect:

bash> expect
expect1.1> set timeout 1
1
expect1.2> spawn vim
spawn vim
24456
expect1.2> expect q

Problem Expect: Readline functionality

Second attempt. Remember to quote ("") arguments.

bash> expect
expect1.1> set timeout 1
1
expect1.2> spawn vim
spawn vim
24456
expect1.3> send "iHello, world!"
expect1.4> expect "foo"
Hello, world!^[[>0;115;0cexpect1.5>

Third attempt. Testing completion (^P)

bash> expect
expect1.1> set timeout 1
1
expect1.2> spawn vim
spawn vim
24456
expect1.3> send "iHello, world! H^P"
expect1.4> expect "foo"
Hello, world! Hello^[[>0;115;0cexpect1.5>

The difficulty with testing Vim with expect is the output of all these terminal escape codes. Can they be filtered? But they might be needed for testing. I'd better output the state of Vim to a text file and use this text file for verifying.
