"Expected first tab to have type 'courseware'. tabs:
'{0}'".format(tabs))
-----------
It does look the tab of type "courseware" is expected before "course_info".
However, on edx.org(and edge.edx.org), the default order is "course_info"
followed by "courseware" and there is no way to reorder these two
tabs(other tabs such as Wiki and user-added pages can be reordered). So
there seems to be no way to resolve this except to make a code change. On
Dogwood.3 as well as Cypress, the order is "courseware" followed by
"course_info".
Is there a way to avoid the code fix?
Thanks!
Aparna
