Error while running single BokChoy acceptance test case.

[Pravin Chavre]

Hello!
I am trying to run a single BokChoy acceptance test using instructions given here: https://github.com/edx/edx-platform/blob/master/docs/testing.rst

It says:
"To execute only a certain test case, specify the file name, class, and test case method:
paver test_bokchoy -t lms/test_lms.py::RegistrationTest::test_register
"

I tried to run the test_all_sections_and_fields_are_present test case using the above command as follows.

paver test_bokchoy -t lms/test_account_settings.py::AccountSettingsPageTest::test_all_sections_and_fields_are_present

This gave an error as follows:
