Before, we'd show a helpful error message when a task isn't running
instead of erroring in a generic way. Turns out when an alloc is
terminal but reachable, the filesystem is left behind so we were hiding
it.
Now it is always shown and in the event that something errors, it'll
either be generic, or--more commonly--a 404 of the allocation.
This makes use of the PR I recently had merged to eslint-plugin-ember-a11y-testing
to add linting that ensures an accessibility audit is called at least once per acceptance
test file. When I have added linting for component tests, it can apply there too.
I added exclusions for the filesystem browser tests, which are covered by behaviors/fs
and for the search test which will involve significant overrides to Ember Power Select
default templates.
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.
