This closes#10146.
Because of cibernox/ember-power-select#1203, which documents
the current impossibility of attaching test selectors to a
PowerSelect invocation, this uses test selectors on parent
containers instead, occasionally adding wrappers when needed.
I chose to leave the existing test selectors in the hopes that
we can return to using them eventually, but I could easily
remove them if it seems like extra noise now.
Presumably for the same reason, @class no longer works, so
this adjusts the scoping of global search CSS to preserve the style
of the search control.
I also included an update to the latest version of
ember-test-selectors, since we were far behind and I tried
that before finding the aforelinked issue.
Finally, this replaces ember-cli-uglify with ember-cli-terser to address
production build failures as described at ember-cli/ember-cli#9290.
This continues #8455 by adding accessibility audits to component integration
tests and fixing associated errors. It adds audits to existing tests rather than
adding separate ones to facilitate auditing the various permutations a
component’s rendering can go through.
It also adds linting to ensure audits happen in component tests. This
necessitated consolidating test files that were scattered.
This introduces ember-a11y-testing to acceptance tests via a helper
wrapper that allows us to globally ignore rules that we can address
separately. It also adds fixes for the aXe rules that were failing.
This partially addresses #7799.
Task state filesystems are contained within a subdirectory of their
parent allocation, so almost everything that existed for browsing task
state filesystems was applicable to browsing allocations, just without
the task name prepended to the path. I aimed to push this differential
handling into as few contained places as possible.
The tests also have significant overlap, so this includes an extracted
behavior to run the same tests for allocations and task states.
