Reviewer's GuideThis PR delivers three 2.0 fixes: unmatched masking selectors return immediately, core reporting always emits accurate run totals while HTML report paths remain opt-in, and disabled Minitest screenshots no longer inflate assertion counts. It adds coverage for real-browser timing, reporter-independent and parallel summaries, Rails missing-assertion behavior, and updates configuration/reporting documentation.

) Capybara's `all` defaults to `minimum: 1` and blocks in `synchronize` until that count is satisfied, so every `skip_area` (or `crop`) selector matching nothing burned a full `Capybara.default_max_wait_time` -- 5s by default, per selector, per screenshot. Measured with a real browser at Capybara's shipped 5s default, `%w[picture img]` against an image-less page: 10.012s before, 0.009s after. One project reported that exact scenario as 44% of their whole suite. The cost is only half of it. `skip_area` is a MASK -- "exclude whatever is currently there". Waiting for an element to appear is the wrong semantic: a selector matching nothing has nothing to mask, and that answer is available immediately. `all_visible_regions_for` is the only Capybara finder in lib/; the rest of BrowserHelpers is execute_script/evaluate_script and driver introspection, none of which carry a count expectation to block on. So this is the class of bug, not one instance of it. The guard uses a REAL browser session. Every existing test of this path stubs the browser, and a stub answers instantly whether or not the selector matches -- which is exactly why a 5-second wait went unnoticed for years. Its budget is derived from the live `default_max_wait_time` rather than hardcoded, so lowering the suite's wait cannot quietly turn it into an assertion that passes while broken.
`SnapDiff::Reporting.register` appears exactly once in the whole gem, at
reporters/html.rb:140. So the honest summary line shipped bundled with
the HTML report, and the documented Rails setup registered nothing:
$ ruby -e 'require "snap_diff/integrations/minitest"
puts SnapDiff::Reporting.reporters.size'
0
That line exists to catch the failure modes no per-assertion rule can
see -- a run where zero system tests executed, or where an inherited
GIT_DIR redirected every baseline lookup. `0 verified` is the only
signal for either, and it was behind an opt-in require.
Separates the two concerns: counting is core honesty, writing an HTML
file is a feature. Reporting owns `verified`/`changed` and prints
`counts_summary` unconditionally from `finalize!`; Reporters::HTML keeps
the report file, stays opt-in, and its `summary` is now just the path of
the file it wrote -- on its own line, and nil when it wrote nothing. So
the counts print exactly once whether or not the reporter is loaded, and
`0 verified` still shouts NOTHING WAS VERIFIED.
The fork-parallel merge (#266) carries the new counters in the same
fragment as the missing-baseline names, and its guard now goes through
`Reporting.notify` -- the real path -- so it checks both halves the
worker has to hand back.
`count` warns and skips rather than raising: `notify` runs inside every
test's teardown, and a raise there aborts SnapDiff.reset before it
clears the registry, leaking one test's assertions into the next. Same
contract the reporter loop already applies, and just as loud
(unconditional, not DEBUG-gated). Adding it surfaced three test doubles
that never implemented Comparison's `difference` reader -- they had been
blowing up unnoticed inside HTML#record, which swallows under
`if ENV["DEBUG"]`.
docs: `configuration.md` recommended the LEGACY `Capybara::Screenshot.enabled`
spelling inside the canonical config reference, in three places.
`integrations/minitest.rb` incremented the counter before the `active?`
guard inside `super`, which returns false immediately when screenshots
are disabled. So a test whose only assertion was a screenshot reported
`1 runs, 1 assertions, 0 failures` -- nothing captured, nothing
compared, and a green line claiming otherwise.
Counting only when active hands the alarm to Rails for free. Rails
unconditionally prepends ActiveSupport::Testing::TestsWithoutAssertions
into every ActiveSupport::TestCase (test_case.rb:205), so those tests
now warn:
Test is missing assertions: `test_it` .../my_test.rb:12
Guarded in both directions with the real Rails module, not a stand-in:
the alarm fires for a test whose sole assertion was a disabled
screenshot, and stays quiet both for a test that asserts something else
and for a screenshot that actually ran.
Audited the other two adapters, neither needs a change:
- RSpec's matcher returns a literal `true`, which is correct rather than
the same bug: returning `assert_matches_screenshot`'s false would fail
the example over a config switch the user set on purpose, and a real
mismatch raises rather than returning false. RSpec has no assertion
count to correct and no missing-assertion alarm to trigger, so only
the end-of-run `0 verified` line can see a disabled run. Said so at
the call site, since the next reader will otherwise "fix" it.
- Cucumber counts nothing; `SnapDiff::DSL#assert_matches_screenshot`
already returns false when inactive.
These three checks could not have been written before the rebase: the counts line (#269) and record modes (#274) never met until now. - The fork-parallel fragment carries BOTH tallies, so a worker that counts assertions AND re-records a baseline must hand back both and neither may cost the other. The main merge case now does both. - A fragment with none of the keys added since #266 still merges. The fragments directory is keyed by pid under the system temp dir, so a recycled pid can hand the merge a fragment written by an older version of the gem; every key but "missing_baselines" is read with a default for exactly that. Mutation-checked: dropping one default fails the merge with `TypeError: nil can't be coerced into Integer`. - `record: :all` end to end, on a finished process. It re-records without comparing, which through the summary path is neither verified nor changed, and NOT "new" either -- there was a baseline, it just was not consulted.

ActiveSupport::Testing::TestsWithoutAssertions Rails source missing assertions test_case.rb
💡 Result:
ActiveSupport::Testing::TestsWithoutAssertions is a module in Rails designed to warn developers when a test case runs without performing any assertions [1][2]. It is located at activesupport/lib/active_support/testing/tests_without_assertions.rb and is included in ActiveSupport::TestCase via the prepend method [3][2][4]. The module works by overriding the after_teardown method [1][2]. After calling super, it checks the number of assertions performed; if the count is zero and the test did not end in an error or skip state, it issues a warning that includes the test name and its file location [1][2]. If you are looking for this in your codebase and feel it is missing, verify your Rails version. It was introduced to help identify broken or incomplete tests [1]. You can confirm its presence by checking if the file exists in your ActiveSupport directory or by inspecting the ActiveSupport::TestCase class ancestry in your environment [3][5][6]. If you are using a very recent version of Rails, ensure you have not accidentally disabled this functionality through custom configuration or third-party test suite overrides [2].

Keep tallying after one malformed assertion.
If compare.difference raises for one assertion, count exits before it adds either local counter. Later valid assertions in the same batch are not counted. The reporters still receive the batch, so the HTML report can contain comparisons while the run summary reports NOTHING WAS VERIFIED.
Rescue per assertion inside the loop. Keep tallying the remaining assertions.

… that never matched (#277) (#279) * feat: an optional readiness block on the screenshot DSL (#277) `assert_matches_screenshot` and `capture_screenshot` return at the `active?` guard before doing anything else. So readiness scaffolding written on the line above -- `preload_all_images`, `document.fonts.ready`, waiting on a widget -- still runs when screenshots are DISABLED, and in a real consumer that is three browser round-trips (scroll to bottom, an `assert_text` with its own wait, scroll back) per screenshot that is never taken. Turning visual tests off was free except for the scaffolding, and the scaffolding is the expensive part. Both methods now take an optional block, run after the guard and before the capture. `screenshot` and `assert_no_screenshot_changes` forward it -- a delegator that swallowed it would hand the user a block that silently never runs. Deliberately NOT a hook: no config-level `before_capture`, no after-hooks, no block on Comparison. It runs once per assertion, not once per stability attempt (a per-attempt block is a different feature and a separate decision), and an error raised inside it is the user's own and propagates unchanged. RSpec's `match_screenshot` matcher does not take one: `expect(page).to match_screenshot('x') { ... }` binds the block by Ruby's `{}`/`do...end` precedence rather than by intent. RSpec and Cucumber users call `assert_matches_screenshot` directly, where the block is unambiguous. Also drops the docs' claim that an unmatched `skip_area` selector waits for the element -- untrue since #272 -- and says what replaced it: the mask covers what exists at assertion time, and late-loading content belongs in the block. * feat: name the selectors that never matched anything, once per run (#277) Removing the implicit wait (#272) took a measured 44% off a real suite, but that wait was also, accidentally, giving late-loading elements time to appear. A `skip_area` selector that matches nothing now yields an EMPTY mask, silently: nothing excluded, the unstable region compared, the test flakes -- and the only tell is a flake weeks later. #275 deliberately declined a per-screenshot warning, and was right to: the gem cannot tell a typo from a legitimately image-less page, so the legitimate case would fire on every screenshot until people stopped reading it. A RUN-level tally has no such problem. A selector that matched somewhere is doing its job and is never mentioned; one that matched nowhere in the entire run is a typo or a stale selector with high probability. Fed from BrowserHelpers.bounds_for_css, the one seam that still knows which selector produced which regions -- AreaCalculator sees only the flattened list -- so a selector that was configured but never reached can never be named. Two sets rather than a counter, because under fork-parallel (#266) the hit and the miss for one selector arrive from different processes and only the parent that merged every fragment can answer "did this match ANYWHERE"; both halves ride the existing fragment alongside verified/changed/new, `fetch`ed with defaults like every key added since. Silent when the set is empty, on purpose. A line that prints on every run is a line users learn to skip, which is how this one would stop working.

Three 2.0 fixes, one commit each, plus a fourth commit for the interactions the rebase onto #274

1.
skip_areaselectors that match nothing blocked for 5s each (#272)Capybara's
alldefaults tominimum: 1and blocks insynchronizeuntil that count issatisfied, so every
skip_areaselector matching nothing burned a fullCapybara.default_max_wait_time— 5s by default, per selector, per screenshot.Measured with a real browser at Capybara's shipped 5s default,
%w[picture img]against animage-less page:
A reporting project measured that exact scenario as 44% of their whole suite.
The cost is only half of it.
skip_areais a mask — "exclude whatever is currently there".Waiting for an element to appear is the wrong semantic: a selector matching nothing has nothing
to mask, and that answer is available immediately.
all_visible_regions_foris the only Capybara finder inlib/— the rest ofBrowserHelpersisexecute_script/evaluate_scriptand driver introspection, none of which carry a countexpectation to block on. So this is the class of bug, not one instance of it.
The guard uses a real browser session. Every existing test of this path stubs the browser, and
a stub answers instantly whether or not the selector matches — which is exactly why a 5-second
wait went unnoticed for years. Its budget is derived from the live
default_max_wait_timeratherthan hardcoded, so lowering the suite's wait cannot quietly turn it into an assertion that passes
while broken.
Should an unmatched selector be reported? — no
The gem cannot tell a typo from "this page has no images", and under the mask semantic zero
matches is a legitimate answer. A per-screenshot warning would fire on every screenshot of the
legitimate case, and the user could not silence it without deleting the selector they want kept.
The silent no-ops this release has been eliminating are ones where the gem knew something was
wrong (no baseline committed, a path it invented); here it does not.
If typos turn out to be a real support burden, the cheap upgrade is a run-level tally of selectors
that matched nothing in every screenshot of the run, printed on the summary line — never
per-screenshot.

0 verifiedline can see a disabled run; that reasoningis now a comment at the call site so the next reader does not "fix" it. Cucumber counts nothing.

Rebase resolution onto #274
Four conflicted hunks. "Keep both sides" is right for two of them and wrong for the other two.
lib/snap_diff/reporting.rb— state variables → keep both. #274's@rerecorded_baselinesand this branch's
@verified/@changedare independent tallies.lib/snap_diff/reporting.rb— fragment payload → keep both. Both sets of keys ride the sameworker fragment.
lib/snap_diff/reporting.rb— the merge → keep both, under one lock, with #274's instinctextended. #274 read its new key with
fetch(..., [])because an older worker's fragment doesnot have it. That reasoning applies to
verified/changedtoo, so they arefetched with0.Only
missing_baselinesis read bare — it is the one key every version of this fragment has everwritten. The real exposure is not an "older worker" but a recycled pid: the fragments
directory is keyed by pid under the system temp dir, so a stale fragment from an older install can
reach this merge. Now pinned by a test, and mutation-checked.
test/test_helper.rb— NOT keep both. #274 callsreset_missing_baselines!/reset_rerecorded_baselines!; this branch replaced that surface withreset_run_totals!. Keepingboth leaves calls to methods that no longer exist. The resolution is the single surface that
covers every tally
finalize!reports —reset_run_totals!now clears all four, #274'sper-tally reset is deleted as dead, and its one caller in
record_modes_test.rbpoints at theunified surface. One surface so a tally added later cannot be forgotten at the call site.
docs/configuration.md— NOT keep both, and not simply "my side wins" either. My side stillcarried the
fail_if_newCI-default note that #274 deleted and replaced with the whole Recordmodes section; dragging it back would contradict that section. Only the spelling correction
survives. (All three legacy-spelling fixes confirmed present post-rebase; the occurrences that
remain in
docs/are the ones that name the legacy spelling in order to map it to the canonicalone, which is correct.)
record: :allthrough the new summary pathThis interaction did not exist when either PR was written.
record: :allre-records withoutcomparing, so those screenshots are neither verified nor changed — and not "new" either, which
is a different fact: there was a baseline, it just was not consulted.
Left alone, a
record: :allrun would have ended on0 verified … NOTHING WAS VERIFIED. That shout exists to catch accidents — a suite that ranzero system tests, a
GIT_DIRpointed at the wrong repository. Underrecord: :allit is a falsealarm at a user who asked for exactly this, and false alarms are how the real alarm stops being
read. So the counts line now names the re-recording, and suppresses the shout only when
re-recording explains the zero:
An unexplained zero still shouts, and
record:being a per-screenshot option means a mixed runreports both (
1 verified … 1 re-recorded). Asserted on a finished process, not in-process.Noted, not fixed (out of scope)
