I queued my hops beside the loop,
A scoped choice led me through the group.
Old tests found a Catch2 home,
New checks watched each queue that roamed.
I thumped the build, then munched a leaf.

Review comments at @indra/newview/tests/alscriptreferencespane_test.cpp:
- Around line 157-163: Add non-continuing row-count requirements before indexing
results from getAllData in this test, including the rows vector and the accesses
at indices 3 and 0. Require at least four rows before index 3 and at least one
before index 0, while preserving the existing checks.
Review comments at @indra/newview/tests/alscriptregionusage_test.cpp:
- Around line 170-172: In the attachment-answer test, add a non-null assertion
for usageOf(id(2)) before accessing its memory, so the test fails cleanly if
that usage entry is absent.

Code that works off the main thread hands what it found back through the queue the main loop services; where there is none, in a test, it does the work in place. Nine places asked for that queue by its name, so in one test process a queue one test made under that name chose the way for every test after it: alscriptlookup's walks went to a thread for the cases that rely on their being done in place. They ask ALMainLoop::queue() now. It answers as they did, unless a test holds an ALMainLoop::Choice, which says which queue it answers, or none, for as long as it lives. newview's test queue no longer has the main loop's name, so making it chooses nothing; alscriptlookup's threaded case and alscriptstudiomasters' fixture choose it for themselves. Ahead of TM24, where newview's tests share one process. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
TM24, the last wave of stage 3: newview's 85 TUT files, 832 tests, become thirteen Catch2 binaries, each file still run in a process of its own: - newview_tests, 72 files: the models, and Script Studio's units, many built over one headless UI on the source tree's skins and fonts. The viewer has no library, so the 74 files of it they need are compiled into the binary once each, where each test compiled its own copies; al_studio_test_common, the archive the Script Studio tests shared, goes. llvocache.cpp, which leaves out what reads the viewer's settings under LL_TEST, is an object library of its own with that define, since the viewer compiles the same file without it; - newview_gl_tests, the two that draw on llrender's shared hidden window: the selection outline and the depth under the HUD; - a binary each for the eleven Linden-era tests whose hand stubs of llui, llxml and the viewer differ from one another: lldateutil, lllogininstance, llremoteparcelrequest, llsecapi, llsechandler_basic, llslurl, lltextureinfo, llviewerhelputil, llviewernetwork, llworldmap and llworldmipmap. They take llui's headers, which the viewer's precompiled header names, without its library. The fakes, the studio's stand-ins and the settings group are SUPPORT objects. The files are tut2catch.py's output, with the names the idiom pass that follows chose. It marked one site TM-CHECK, in code this Mac does not compile, resolved by hand: noise's comparison with MSVC's rand() (an ensure_equals() over its draws). tut_parity.py, against the TUT executables' recorded results (832 tests, 830 ok and 2 skipped), holds plain for 84 files and under --recounted for noise, with one assertion site reviewed as never running in a passing case: alselectionoutline_gl's check of the unreversed depth, which runs only under reverse-Z, where the context has clip control, as this Mac's GL 4.1 context does not. All 98 entries pass, and newview_tests passes whole, in declared order and in random ones. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The idiom pass over TM24's conversion, by twelve agents on copies, merged back onto it. Names, messages and assertion strength only: every case and every assertion is where the conversion put it. - Names: 782 of 832 changed. Most were set_test_name sentences or the first sentence of a comment, 501 had commas, which a Catch2 test spec reads as "or", and the Linden tests' were "#1" and the like. Where a shorter name dropped a why, a comment above the case keeps it. - Messages: 5,480 to 3,841, with 180 CAPTUREs. Most of those removed restated their check, or numbered it; most that remain say which step, pass or input a failure is at. A few that described another check than their own say what theirs checks. - 11 asserting helpers are named for it: require_pane, require_saved, require_contains, require_throws_with_cert and the like, and in llvocache, which names its helpers in camel case, requireSameEntry. - 21 CHECKs whose subject the next lines index or follow are REQUIREs, and 753 REQUIREs that guarded nothing are CHECKs. One of llworldmap's sat inside a try whose catch(...) reported its own failure as a throw. - The selection outline's and the HUD depth's convention loops say which convention with CAPTURE(reverse), and the helper that wrote it into every message is gone. - noise's namespace tut, kept only for the code the converter could not compile, is an anonymous namespace. tut_parity.py holds all 85 files under --recounted, every case's count unchanged, with the conversion's one site reviewed as never running here. Old test bugs the agents found, left as they were: - reads with no guard, where a failure would crash rather than fail: .back() and [n] of what nothing sized (statuses, reports, asks, candidates, did, the explorer's rows, the crumbs' path), a find<>(), findChild(), findDoc(), part(), word() or optional used unchecked, and shared_ptr texts dereferenced, in most of Script Studio's tests; lutcube reads a rejected cube; alcrashreporter indexes past a length; - checks that cannot fail: llviewerassetstats indexes the wrong LLSD level twice, so four checks compare undefined with 0; llsechandler_basic's grid checks read the credential it did not change, and its authenticator check reads the identifier again; alscriptregionusage, alscriptnavigation and llworldmap each have one that the setup already decides; lltextureinfo has a CHECK(true) and a case that always skips; llvocache's clamped factor is checked against its own clamp; - checks of something other or less than they say: llagentaccess's "pref adult, actual PG" passes on the preference alone; llviewerhelputil's substitutions are its own stub's; alfeedback's loopback user name is in the path; alscriptstudiovim's "off already" and ":wq over unsaved" steps run something else; the HUD outline case counts only one kind of hidden pixel; comments promising checks that are not there (alscopedata, alscriptstudiorecovery, alscriptstudioaccount, alrecoverykeeper, altexturetable, llhttpretrypolicy and others); - one that leans on evaluation order: alscriptcrumbsbar calls part() twice in one expression, and each call replaces the vector the other points into; - state a failure leaks: llviewerassetstats leaves gViewerAssetStats set, and alscriptsearchpane its sources' cache; - leftovers: unused variables and members inherited from TUT (lllogininstance, llviewerassetstats, alscriptstudiofiles), empty cases (llviewercontrollistener's first, llremoteparcelrequest's second, llworldmipmap's getObjectsTile), duplicated checks in llslurl, and a policy flag given twice in llsechandler_basic.

…t the viewer keeps newview_tests takes llui's and llrender's checks, as llui's binaries do: the headless UI and the colour table made before the first case, what a frame clears cleared after each, and the UI's and the fonts' state watched. newview_gl_tests takes llrender's and llcommon's. newview_test_checks, a listener of newview_tests' own: - before the first case, makes the queue a case chooses to stand in for the main loop's, kept for the run, since work handed back to it for a case gone must find it; - gives the state guard, after every case, the queue ALMainLoop answers, the settings groups alive, Script Studio's recovery store, save history and viewer, and llcommon's checks: the live thread pools and work queues, and LLError's default level. It does not take llcommon's listener, which makes the event pumps afresh after every case: the viewer's own event APIs, LLViewerControlListener among them, listen on the pumps from before main, as they do for the viewer's whole run, and llviewercontrollistener's cases found none after the first. The eleven Linden-era binaries take none of these: each runs alone, and lllogininstance's second case relies on pumps its first made. I broke a case each way, and each check named it. Two threads that live for the process are no change a case made: - the recovery stores' writer is made by newview_test::useRecoveryWriter(), which each fixture that makes a store calls before it does, and is stopped by the harness's teardown. Made at run start, its thread started beside the UI being built, and one start in some hundreds found the heap corrupt, so it starts in a case, as it did when each file had a process of its own; - alscriptlookup's threaded case accepts the disk walks' thread, which its first walk makes, as the process's from then on. newview_tests, newview_gl_tests and the eleven, each run whole, pass 10 random orders and 20 repeats with no guard report.

…hey check Old test bugs TM24's idiom pass found (83b0c1d), fixed. - alscriptstudiovim: "off already: left" turned an option off, and ":wq over something unsaved" ran :x; each runs what it says, and the old steps stay under names of their own. - alrecoverykeeper: "among the discarded" is checked, and so is the write the case relied on; each entry looked up is held and required. - alscriptstudiorecovery: "behind the new one's" checks the order, not only the count; a save with no key is checked to keep nothing; the window's taker, which captured the case's locals, is put back by RAII. - alscriptstudioaccount: the switches said to stay shared are tested with one. - alscriptnavigation: a check the setup already decided checks that nothing was noted. - alscriptregionusage: an answer for an id already recorded checks that the live asker heard it; usageOf() is required before it is read, as review on #474 asked. - alnotecardembedded: a button is checked over each item, and one undo is checked to take only the last away. - alscriptkeymap: the keys are compared, not whether both lists are empty; off the Mac, back and forward are checked apart. - alscriptsnippets: running as root skips, as alfilewrite's test does. - Reports, statuses, sends, tidies, analyses, closed tabs, offers, logs, recent files, watches and prims are required before they are read in these and alscriptstudiosaving, alscriptstudiomasters, alscriptstudioorphans, alscriptstudiofiles, alscriptstudiodoc, alscriptexternaleditor, alscriptrecompile, alscriptcontentsindex and alscriptstudiocommands. Unused variables inherited from TUT are gone. Each new or corrected check fails under a small change to the test's own input or expectation, at the check and not by crashing.
