# End-to-end check of the shared styling contract and the two shipped controls.
|
||
|
|
#
|
||
|
|
# The unit tests cover the store and the components in isolation. This covers the
|
||
|
|
# things only a browser can answer:
|
||
|
|
#
|
||
|
|
# - Does the rendered contract CSS actually resolve to the right computed values?
|
||
|
|
# - Does the legacy alias layer reach a host page that never mentions --bn-*?
|
||
|
|
# - Does Shadow DOM isolate the controls in both directions against a hostile rule?
|
||
|
|
# - Do the controls, driven by a real click, move the attributes on <html>?
|
||
|
|
#
|
||
|
|
# The page verifies itself and writes a verdict into the DOM, so this needs only a
|
||
|
|
# headless Chromium and no driver library.
