These only ever do plain visit/fill_in/click_link/click_button/select against normal HTML forms and links, with no AJAX, no client-side validation, no dynamically-added form elements, and no confirm()/ window/file-input-widget behavior -- rack_test (the Capybara default) handles all of it identically to a real browser, ~15-20x faster per example. Spot-checked one non-obvious case directly rather than trusting appearances: edit_user_profile_spec.rb asserts on a field's `disabled` state, which turned out to be set server-side in the ERB template (`disabled: !can_edit...`), not toggled by JS. Verified by actually running all 10 files together under the default driver: 39 examples, 0 failures.
staff_resources_spec.rb: the top-level tag covered all 16 examples; only "should save edited description" actually does AJAX (confirmed via the view's inline jQuery + the spec's own wait_for_ajax). Verified against the actual view templates before touching anything: the "delete a resource"/"upload a file"/"search for attachments" examples all click plain Rails form submit buttons (form_for ... method: :delete, f.submit, submit_tag inside a form_tag ... method: 'get') with no remote:true or JS handler bound to them. event_management_spec.rb: same shape, but two examples the initial audit called avoidable turned out not to be once actually run under rack_test (RSpec suite is the real gate here, same as every gem upgrade pass in this repo's history): - "should save and render attributes" fills the Location Phone field with send_keys specifically because that field has a JS inputmask ((999) 999-9999) -- fill_in bypasses it, and rack_test's driver doesn't implement send_keys at all (raises NotImplementedError). - "clone a past event" calls Event#attach_photo_from, which performs a real HTTP fetch of the source event's own photo URL via open-uri. That only succeeds when Capybara has booted an actual listening server (true for any real-browser driver, including js: true) -- under rack_test everything is dispatched in-process with nothing listening on that URL, so the fetch raises OpenURI::HTTPError. Confirmed by actually hitting this failure, not by inspection. "clone a past event without copying the photo" avoids this entirely (it checks the photo_delete checkbox, which skips attach_photo_from in EventsController#create) and stays fast. Both files verified by running the whole file after each change: 16 examples / 0 failures each.
Both files mirror each other: a top-level tag over ~18 examples where
only two things are genuinely JS-dependent -- the dynamic add/remove
photo & document widget ("should save the user-entered values", which
adds/removes file inputs via click_link with no page reload), and the
"user enters invalid attributes --client-side validation" context
(inline error messages shown without a server round-trip, per its own
name). "permitted access to fields" (disabled attrs are server-rendered
per !can_add_cats?/!can_edit_cats? in the view), "cancel while adding"
(plain click_link), and "--server-side validation" (a real POST that
re-renders the form with Rails' own error output, per the spec's own
"#uniqueness of name validated on server" comment) all run identically
under rack_test.
Verified by running each full file: 18 examples / 0 failures each.
…dog)
Same shape and same verdicts as the add_cat/add_dog pair: only the
dynamic photo/document widget ("should save the updated values") and
the "--client-side validation" context (inline errors + the same
widget for file-size/type checks) need a real browser. "permitted
access to fields" (server-rendered disabled attrs), "cancel while
editing" (plain click_link), and "--server-side validation" (real POST,
Rails' own error re-render) run identically under rack_test.
Verified by running each full file: 23 examples / 0 failures each.
"comments tabs, small/large screen" contexts call set_screen_size, which does a real window.resize_to -- rack_test's driver doesn't override Capybara::Driver::Base#resize_window_to, so it raises NotSupportedByDriverError outright (confirmed by reading Capybara's own driver source, not just inferring from the name). Everything else in these files (unavailable-status alert, Adoptapet ad text, unpopulated attribute display) is a plain visit + static content assertion. Note: find_link_and_click (spec/helpers/application_helpers.rb) looks JS-dependent at a glance -- it builds an execute_script/scrollIntoView call -- but that line is commented out; the helper only ever calls element.click. Not a factor either way. Verified by running each full file: 19 examples / 0 failures each.
"visit manager view" (sign-in redirect) and "should find dogs matching text partial" (a direct visit with filter_params in the URL, bypassing the search widget entirely) are plain server-rendered page loads. "should show all dogs when search is cleared" and dog_search's "should default select the search_field_index..." both go through #reset_message / the "Search" button inside #dog-search, both of which are click-intercepted by jQuery handlers in animals_index.js (GlobalMultiSelect.fetch_all / .search) rather than real links or form submits -- confirmed by reading the actual delegated click bindings, not just guessing from behavior. Verified by running each full file: 3 examples / 0 failures (cat_search), 4 examples / 0 failures (dog_search).

Root cause: this app has no config/master.key or credentials.yml.enc, so Rails' test-env secret_key_base has always come from its own generate_local_secret fallback (railties' configuration.rb), which does a non-atomic check-then-write against a single shared tmp/local_secret.txt -- create it if missing, then read it back. On a fresh CI checkout that file doesn't exist yet (tmp/ is gitignored), and both parallel:create and parallel_rspec now boot several Rails processes concurrently. If two race to create the file, a loser's File.binread can catch it between the winner's truncate and write and get back "" -- Rails' own secret_key_base= setter rejects that non-nil, blank String with exactly this app's reported error. It's a genuine race (timing-dependent), which is why a rerun usually clears it, and it's connected to going parallel: the old single serial db:create process never had a second process to race against. Verified the mechanism directly: with tmp/local_secret.txt deleted and SECRET_KEY_BASE unset, `Rails.application.secret_key_base` still falls into generate_local_secret; with SECRET_KEY_BASE set, the same call resolves to that value and never touches tmp/local_secret.txt at all (confirmed the file doesn't even get created). Fixed by setting SECRET_KEY_BASE as a fixed, non-secret job-level env var in CI, so the fallback -- and its race -- is never reached in the first place. Not reproduced by trying to force the race locally (15-way parallel locally didn't hit the window in 5 attempts), consistent with it being a narrow, timing-dependent race rather than a deterministic bug.
The following expect(page).to have_selector(filter_params, text: "Tracking ID") already polls up to Capybara's default max wait time for the reset click's AJAX response to land -- the explicit sleep(2) was both redundant and a fixed cost paid on every run regardless of how fast the response actually was. Verified: 5 runs across different random seeds, 0 failures each: no flakiness from relying on the matcher's wait instead. The "search and clear search" example group's average dropped from ~2.0s/example to ~0.38s/example.

application_helpers.rb's four flash_*_message helpers each did
sleep(1) before page.find(...), which already polls/waits on its own
-- pure dead weight on every one of their 21 call sites across the
suite (add_cat/edit_cat/add_dog/edit_dog/cat_search/dog_search/
event_management/staff_resources specs).
event_management_spec.rb's "should delete a past event" had a
sleep(2) immediately before calling flash_notice_message -- redundant
now that the helper waits on its own, same pattern as the earlier
cat_search_spec.rb fix.
cat_filter_spec.rb / dog_filter_spec.rb's "reset filter" examples had
a sleep(2) followed immediately by reading cats_list/dogs_list, a
plain page.all(...) helper with no built-in wait (unlike have_selector,
page.all only retries for a match count, not for existing matches'
content to change) -- so removing the sleep outright would have made
these read stale pre-reset content. Fixed by moving the have_no_selector
('#reset_message') check (already present later in each example) up to
right after the click, giving Capybara something to actually poll on
before the plain list read -- and dropping the now-duplicate check at
the end.
Verified: the 8 files touching these helpers/sleeps run clean across
two full-file seeds (185 examples / 0 failures each), the two filter
specs individually across 5 seeds (64 examples / 0 failures each, no
flakiness from the reordering), and two full-suite runs with different
seeds (743 examples / 0 failures / 12 pending, matching baseline).
Serial wall time: 3m18s -> 2m54s.
Left campaign.spec.rb and donation.rb's sleep()s alone -- both files
are wrapped in `end if false` and never run, so there's nothing to
gain from touching them.
