This line is no longer necessary in new tests. The linters are now aware of
PaymentRequest API.

Done.

Print the address from here instead:

print(JSON.stringify(request.shippingAddress, undefined, 2));

Done.

Technically this test does not require updating price based on the address. You
can simplify this line to "resolve(details);" and remove the updateDetails()
function below.

Done.

[please use gerrit instead, 2017/04/20 15:41:44]

"request.show()" is sufficient. Important print() statement is in the
'shippingaddresschange' event listener. Other print() statements are not
important for this test. (Remove lines 43-54.)
