276-297: ⚠️ Potential issue | 🔴 Critical

tryInitOgre() still doesn't give MockSpaceCamera a valid target.

Lines 199-201 already note that mCameraNode/mTarget are only initialized through the OgreWidget constructor path. These new tests still construct MockSpaceCamera directly, so mouseMoveEvent() can keep hitting the same null-dereference that originally crashed the suite. Drive these cases through a widget-backed camera, or inject a valid target before sending move events.

Also applies to: 325-341, 363-389

src/MCPServer_test.cpp (2)

2606-2617: Test comments describe resource protocol but test tool calls.

The test name and comments suggest testing resource protocol (handleResourcesList), but the actual test calls get_scene_info tool. While testing indirectly is valid since the methods are private, the test name HandleResourcesList_ReturnsResources is misleading since it doesn't actually test resource listing.

Consider renaming to reflect what's actually being tested, or add a comment clarifying the indirect testing approach.

exposure indirectly via server->callTool("get_scene_info", ...) and the
expectation on getResultText(result); ensure references to handleResourcesList,
callTool, and get_scene_info are mentioned so future readers know this is an
indirect verification.

2545-2545: Hardcoded tool count may become stale.

The assertion EXPECT_EQ(allTools.size(), 26) will fail silently if new tools are added to the list but the count isn't updated, or vice versa. Consider removing this assertion since the loop already verifies each tool individually.

Inline comments:
In `@src/FBX/FBXExporter_test.cpp`:
- Around line 2327-2328: The test uses POSIX-only hard-coded paths (e.g.,
"/tmp/fbx_inmem_%1.fbx") which breaks Windows CI; update the FBXExporter tests
to use QTemporaryFile or QTemporaryDir to produce a cross-platform temporary
file path for the success case and construct the invalid path by creating a temp
dir/file and then removing it (or appending a non-existent child name) to ensure
an intentionally-invalid path; change uses of meshCounter-based outPath and any
other hard-coded paths referenced around FBXExporter::exportFBX (also fix the
similar occurrences noted at the other ranges) to build paths via
QTemporaryFile/QTemporaryDir so tests are platform-independent.

In `@src/mainwindow_test.cpp`:
- Around line 1015-1071: These tests directly construct QDragEnterEvent (in
tests DragEnterEvent_AcceptsMeshFiles, DragEnterEvent_AcceptsFBXFiles,
DragEnterEvent_AcceptsOBJFiles, DragEnterEvent_AcceptsDAEFiles,
DragEnterEvent_AcceptsNonMeshFiles, DragEnterEvent_AcceptsEmptyUrls), which is
unsafe; instead either (A) drive a real drag by using QTest mouse events/QDrag
so the Qt drag-and-drop state is initialized, or (B) refactor the acceptance
logic out of MainWindow::dragEnterEvent into a testable helper (e.g.
MainWindow::canAcceptMimeData or a static function taking QMimeData*) and call
that helper from these tests with constructed QMimeData; update the tests to
remove direct QDragEnterEvent construction and assert the helper or real drag
result.

In `@src/MCPServer_test.cpp`:
- Around line 2770-2785: The test uses a hardcoded
"/tmp/mcp_export_temp_test.obj" which is not portable; update the export path
construction to use QDir::tempPath() (as in ExportMeshWithInMemoryEntity) when
creating exportPath and the corresponding material/mtl filenames, e.g. build
exportDir = QDir::tempPath() and join with "mcp_export_temp_test.obj" to form
exportPath, then adjust the QFile::remove calls to remove the same derived
paths; modify the block around the export_mesh call where exportPath,
exportedFile, and cleanup are handled to use these QDir-based paths instead of
"/tmp/".

In `@src/PrimitivesWidget_test.cpp`:
- Around line 502-537: The test uses QWidget::isVisible() which returns false
because the PrimitivesWidget isn't shown; update the assertions in TEST_F
PrimitivesWidgetTest::SetUiEmptyHidesAllFields to call isVisibleTo(&widget)
(e.g., edit_type->isVisibleTo(&widget), gb_Geometry->isVisibleTo(&widget),
edit_sizeX->isVisibleTo(&widget), pb_switchUV->isVisibleTo(&widget), etc.) so
the checks reflect each child's own visibility as set by setUiEmpty(), or
alternatively call widget.show() and process events before asserting—apply the
same change to the related assertions covering lines 539–579.

In `@src/SkeletonDebug_test.cpp`:
- Around line 212-240: The test currently masks missing materials because of the
"|| true" in the EXPECT_TRUE for boneMat and because it uses conditional "if
(boneMat)" instead of assertions, so it can succeed without actual materials;
remove the "|| true" in the EXPECT_TRUE line and replace the `if (boneMat) { ...
}` checks with hard assertions (e.g., ASSERT_TRUE(boneMat) or
ASSERT_FALSE(boneMat.isNull())) before accessing boneMat->getNumTechniques(),
getTechnique(), getNumPasses(), and getLightingEnabled(), and likewise replace
the `if (axisMat)` and `if (selectedMat)` guards with ASSERT_TRUE(axisMat) /
ASSERT_TRUE(selectedMat) (or ASSERT_GT(getNumTechniques(), 0u) immediately after
asserting) so the test fails when materials are missing; use the existing
symbols boneMat, axisMat, selectedMat, getByName, getNumTechniques,
getTechnique, getNumPasses, and getLightingEnabled to locate the changes.

In `@src/TransformOperator_test.cpp`:
- Around line 596-620: The test fixture leaves the SelectionSet singleton in a
stale state across tests; update TransformOperatorTestFixture::SetUp() (and
optionally TearDown()) to explicitly clear the selection by calling
SelectionSet::getSingleton()->clear() (or the project’s equivalent
clearSelection/reset method) and assert SelectionSet::getSingleton()->isEmpty()
before running tests so AllOperations_EmptyScene is order-independent; ensure
the fixture uses these calls (and remove any reliance on external tests to reset
SelectionSet).

🌐 Web query:

Qt QDragEnterEvent documentation warning: "Do not create a QDragEnterEvent yourself"

💡 Result:

In Qt’s drag-and-drop system, QDragEnterEvent instances are created and populated by Qt during an active drag operation. Even though the class has a public constructor, the docs warn you not to instantiate it because the event’s behavior depends on Qt’s internal drag-and-drop state (the drag manager / current drag context), which your manually-created event won’t set up correctly—so results are undefined or incomplete. [1]

If your goal is testing or simulating drag & drop:

  • Prefer simulating the real user interaction that triggers QDrag::exec() (e.g., with QTest::mousePress/mouseMove/mouseRelease) rather than fabricating QDragEnterEvent. [2][3]
  • If you do post synthetic QDragEnterEvent/QDropEvent to a widget, it may only cover limited logic (and can fail for anything that relies on event->source() / actual drag lifecycle). [3]

Sources:
[1] Qt 6.10 QDragEnterEvent docs (warning about internal state) (doc.qt.io)
[2] Stack Overflow discussion noting manual construction is discouraged due to internal state (stackoverflow.com)
[3] Qt Forum thread on testing drag & drop (limitations of posting events; suggests QTest mouse simulation) (forum.qt.io)

Citations:


Avoid constructing QDragEnterEvent directly in tests.

Qt's documentation explicitly warns against manually instantiating QDragEnterEvent because the event depends on Qt's internal drag-and-drop state, which manual construction does not establish. This results in undefined behavior and incomplete event state, making tests fragile and platform-dependent.

At lines 1018, 1027, 1036, 1045, 1058, 1067, and 1293, the tests construct QDragEnterEvent directly. Instead, drive real drag interactions using QTest::mousePress/mouseMove/mouseRelease or extract and unit-test the acceptance logic independently.

Hard-coded /tmp/ paths break Windows CI.

These tests use POSIX-only paths like /tmp/fbx_inmem_%1.fbx and /nonexistent_directory_xyz/sub/test.fbx. Windows CI will fail before exercising the actual export logic. Use QTemporaryDir/QTemporaryFile to construct portable paths.

Use QDir::tempPath() here instead of hardcoding /tmp.

This suite is expected to run in cross-platform CI, and "/tmp/..." will fail on Windows. Reuse the portable temp-base pattern already used by ExportMeshWithInMemoryEntity so the export path and cleanup are derived from the same location.

These “protocol edge case” tests bypass the protocol handlers they’re named after.

HandleInitialize_ReturnsServerInfo and HandleToolsList_ContainsAllTools only use callTool(), and DoubleInitialize just constructs a second MCPServer. None of them send an initialize or tools/list request, so regressions in server info/capabilities, tool metadata, or initialize idempotency would still pass. HandleToolsList_ContainsAllTools also duplicates the earlier HandleToolsList smoke test.

The new resource-protocol coverage here is a false positive.

These cases only hit normal tool calls and the unknown-tool branch; they never exercise resources/list / resources/read with an actual resource URI. A break in resource registration, URI parsing, or resource dispatch would still let this block pass.

277-297: ⚠️ Potential issue | 🔴 Critical

Null pointer dereference in Ogre interaction tests.

MockSpaceCamera is constructed with the default constructor, which leaves mCameraNode and mTarget as nullptr. When mouseMoveEvent() or wheelEvent() are called, they invoke arcBall(), pan(), or zoom() which immediately dereference these null pointers. Initialize the camera nodes in the test setup (e.g., by constructing with a valid OgreWidget* parent or by manually populating the nodes in the fixture), or guard the handler calls with null checks.

Use QDir::tempPath() here instead of /tmp.

1015-1071: ⚠️ Potential issue | 🟠 Major

Stop constructing QDragEnterEvent directly in these tests.

Sending a stack-constructed QDragEnterEvent does not exercise a real Qt drag lifecycle, so these cases are platform-fragile and can pass without validating the production path. Either drive an actual drag with QTest, or extract the acceptance logic into a helper and test that helper directly.

As per coding guidelines, **/*_test.cpp: Tests must work under Xvfb (headless X11) and avoid assumptions about a real display.

- Around line 1152-1163: The test LoadModel_NonExistentModel doesn't assert the
failure path; replace the fixed QThread::msleep with a proper wait/assert using
QSignalSpy or QTRY_* utilities: use QSignalSpy errorSpy(manager,
&LLMManager::modelLoadError) and call manager->loadModel(...), then wait for the
signal (e.g. errorSpy.wait(timeout) or QTRY_VERIFY(errorSpy.count() > 0)) and
assert the expected failure (errorSpy.count() > 0) or alternatively assert the
manager reports no loaded model (e.g. verify manager->isModelLoaded() is false
or manager->currentModel() is empty) so the test deterministically verifies the
error path instead of only relying on no crash.
- Around line 983-1001: Make the test deterministic by forcing a fresh temp
models directory and disabling auto-load before exercising the singleton: in the
test (LLMManagerTest) capture the current singleton via manager =
LLMManager::instance(), save/backup the original auto-load setting and models
directory, then call manager->setAutoLoadOnStartup(false) and
manager->setModelsDirectory(tempDir.path()) (or use the manager/settings API
available) so tryAutoLoadModel() cannot find real models; run the assertions
(isModelLoaded(), isLoading(), isGenerating(), currentModelName()), and finally
restore the original auto-load setting and models directory to avoid global test

entities via createAnimatedTestEntity that produce distinct skeletons and then
discards the checked value of actionMerge->isEnabled(), so it doesn't actually
verify the enabled state; either rename the test to reflect
"NoCrash_SelectionRecalc" and assert only that update/selection changes don't
crash and that the button becomes disabled after clearing the selection, or
modify the setup to produce two truly compatible entities (e.g., create one
skeleton instance and pass it into a second entity or clone the same Skeleton
pointer used by createAnimatedTestEntity) then select both via
SelectionSet::getSingleton()->selectOne/append, call app->processEvents(), and
assert EXPECT_TRUE(actionMerge->isEnabled()) before clearing the selection and
EXPECT_FALSE(actionMerge->isEnabled()) afterwards so the intent of
actionMerge->isEnabled() is actually verified.

In `@src/MaterialEditorQML_test.cpp`:
- Around line 2322-2348: The test ApplyMaterial_ColorsReflectedInOgrePass
currently only checks shininess; after reloading the material via
editor->loadMaterial(editor->materialName()) you must also assert that the
ambient/diffuse/specular/emissive colors round-trip by comparing
editor->ambientColor(), editor->diffuseColor(), editor->specularColor(), and
editor->emissiveColor() to the originally set QColor values (red, green, blue,
yellow) using appropriate equality/fuzzy color checks (e.g., EXPECT_EQ or color
component comparisons) so the test actually verifies color serialization in
addition to shininess; alternatively, if you don’t want to add asserts, rename
the TEST_F to reflect it only verifies shininess round-trip.
- Around line 2285-2304: The test TEST_F(MaterialEditorQMLWithOgreTest,
ExportAndImportMaterial_RoundTrip) uses a hard-coded exportPath
"/tmp/round_trip_test.material" which breaks on non-Linux CI; replace this with
a portable temporary file/dir approach (e.g., QTemporaryFile or QTemporaryDir or
QDir::tempPath()) to produce a writable path, use that path when calling
editor->exportMaterial(...) and editor->importMaterialFile(...), ensure the
QTemporaryFile is closed if necessary before export and remove the temp file in
cleanup instead of QFile::remove("/tmp/..."); this change should be applied
around the exportPath variable and calls to exportMaterial/importMaterialFile.

In `@src/MeshImporterExporter_test.cpp`:
- Around line 656-685: The test ExportImport_FBX_WithSkeleton_RoundTrip
currently only checks file creation and node count; after reimport it should
locate the newly added scene node/entity (use
Manager::getSingleton()->getSceneNodes().last() and scene manager via
Manager::getSingleton()->getSceneMgr()), retrieve the entity for that node
(sceneMgr->getEntity(sn->getName())), and assert entity->hasSkeleton() (and
optionally assert presence of animations via entity or skeleton animation APIs
you use elsewhere) so the round-trip actually verifies the skeleton was
preserved; add analogous assertions in the similar test referenced (lines
689-717).

In `@src/TransformWidget_test.cpp`:
- Around line 214-220: The test TransformWidgetTests::ScaleSpinBoxMinimum only
asserts scaleX non-null but immediately dereferences scaleY and scaleZ; add
explicit null assertions for both (e.g., ASSERT_NE(scaleY, nullptr);
ASSERT_NE(scaleZ, nullptr);) before the EXPECT_GT checks so the test fails
cleanly if either is missing rather than crashing—place these ASSERT_NE calls
alongside the existing ASSERT_NE(scaleX, nullptr) at the top of the test.

Make these singleton-state tests deterministic.

These cases still depend on whatever LLMManager::instance() picked up from persisted settings and the real models directory. On a machine that already has auto-load enabled or a local .gguf, EXPECT_FALSE(manager->isLoading()) can flip and tryAutoLoadModel() can load a real model instead of exercising the “no models available” path. Please force a fresh temp models directory and explicitly disable/restore auto-load inside the test.

⚠️ Potential issue | 🟠 Major

This test never verifies the enabled state it claims to cover.

The setup explicitly uses entities that may be incompatible, then discards actionMerge->isEnabled(). If the button never becomes enabled for two compatible entities, this still passes. Please either rename this to a no-crash/selection-recalc test or build two actually compatible entities and assert true.

The “colors reflected” test never asserts any color state.

Right now this only proves shininess round-trips. If ambient/diffuse/specular/emissive serialization breaks, the test still passes. Please either assert the reloaded colors explicitly or rename the test to match what it actually verifies.

These “protocol edge case” tests still bypass the protocol handlers.

They only call callTool() or construct a second MCPServer, so regressions in initialize / tools/list metadata or initialize idempotency would still pass. This also overlaps the earlier HandleToolsList smoke test instead of covering the protocol path it is named after.

These singleton-state tests are still environment-dependent.

They assume no saved auto-load setting and no real model files in the configured models directory, but LLMManager::instance() is reused as-is. On a machine that already has auto-load enabled or a local .gguf, both EXPECT_FALSE(loaded) and the “no models available” path can flip nondeterministically.

Avoid constructing QDragEnterEvent directly in tests.

Qt expects drag-enter events to be created during a real drag lifecycle. Manually instantiating them skips that internal state, so these acceptance checks are brittle and platform-dependent. Prefer driving an actual drag interaction or extracting the acceptance logic behind dragEnterEvent() into a helper that can be tested from QMimeData.

⚠️ Potential issue | 🟠 Major

This test never verifies that animation time advanced.

timeBefore, timeAfter, and timeAfterStop are read but never compared, and the only assertions are on flags the test sets itself. A regression where frameRenderingQueued() stops advancing animations would still pass here.

⚠️ Potential issue | 🟡 Minor

Round-trip test never validates the import step.

editor->importMaterialFile(exportPath) has no observable postcondition here, so a silent import failure still passes. Either assert a visible import result or rename this to a smoke test.

⚠️ Potential issue | 🟠 Major

Use the actual stop parameter and verify the animation state flips.

This test stops play_animation with stop = true, but the later success-path test uses play = false for the same API. As written, this can pass without ever covering the stop branch, and it never asserts that playback was disabled afterward.

⚠️ Potential issue | 🟡 Minor

Lock down the objnomtl contract.

Both tests only assert that the exported model file exists. If the exporter regresses and writes an .mtl sidecar again, the tests still pass because cleanup just deletes it.

Add the missing no-`.mtl` assertion
     ASSERT_EQ(MeshImporterExporter::exporter(node, "./nomtl_export.objnomtl", "OBJ without MTL (*.objnomtl)"), 0);
     EXPECT_TRUE(QFile::exists("./nomtl_export.objnomtl"));
+    EXPECT_FALSE(QFile::exists("./nomtl_export.mtl"));

Apply the same check in TEST_F(MeshImporterExporterTest, ExportOBJNoMTL_FromImportedMesh).

Also applies to: 1041-1056

⚠️ Potential issue | 🟡 Minor

Attach the spies before the empty-scene operations.

The first no-op batch runs before any QSignalSpy is connected, so those emissions are invisible, and deleteSpy is never asserted. This doesn't currently prove the "no signals" claim.
