Migrate //scouting:scouting_test to Protractor
This framework automatically takes care of the webdriver/selenium
setup. It just lets us focus on writing tests.
This patch migrates the scouting test to use Protractor. It validates
that the application loads correctly and displays the only message
that exists so far.
I can confirm that that test uses a sandboxed version of the chromium
browser:
$ bazel cquery 'somepath(//scouting:scouting_test, @org_chromium_chromium_linux_x64//:metadata)' 2>/dev/null
//scouting:scouting_test (cdf6808)
//scouting:scouting_test_chromium-local (cdf6808)
@io_bazel_rules_webtesting//browsers:chromium-local (3ee7ec9)
@io_bazel_rules_webtesting//third_party/chromium:chromium (3ee7ec9)
@org_chromium_chromium_linux_x64//:metadata (3ee7ec9)
I based the test itself on the upstream example code:
