See test test_settings_with_trailing_whitespace in
test/settings/TestSettings.py.
A test I added here looks like:
# language
self.runCmd ("settings set target.language c89") # Set to known
value
self.runCmd ("settings set target.language pascal ") # Set to new
value with trailing whitespace
self.expect ("settings show target.language",
SETTING_MSG("target.language"),
startstr = "target.language (language) = pascal")
self.runCmd("settings clear target.language", check=False)
How would you write this test using the Python API?

I don't think anyone is against using the Python API, but it needs to be easier
to learn and use before folks will adopt it over self.expect. self.runCmd and
self.expect are straight forward and it's easy to quickly write tests using it.
If you make it too hard to write tests, you'll deter folks from writing tests
for
the features they add.

That would be a cool project to give to some poor college students working on a
branch :)
