Provide Promise polyfill in test runner. This allows tests
of objects which use Promise directly to be run in environments
which don't yet implement Promise (including command line
test environment.) Completing test suite for framework layer,
WTD-518.
Change the way missing test suites are detected by
the test runner; PhantomJS (used for executing tests
from the command line build) does not appear to give
consistent HTTP status codes, so use a more general
try-catch mechanism.
Addresses an issue introduced during ongoing
development of framework layer, WTD-518.
Ignore bundles for which no test suites have been defined.
Used to support development of framework layer (don't
stall the test runner just because some bundle does not
have defined tests yet), WTD-518.
Don't request json as an XHR response type, as this
is not supported by Phantom for command line test
execution. Part of ongoing intitial repository and
build setup for WTD-519.
Add clarifying comments to temporary files, to
ensure they are distinguishable as placeholders.
Part of developing project folder structure and
build for WTD-519.
