Tests: two desktop tests pass on a fast Mac - #7417
Two tests in vectorcraft-ui-egui fail on main (1e4e3534f) on my Mac (MacBook Pro, M4 Pro, macOS), with no other
change. Both are in the tests, not in the app. This changes the two tests only.
Texture "canvas" has size 9982x9925, but the maximum texture side is 8192
The test calls ctx.set_zoom_factor and draws its first canvas frame in the next pass. In the pass where a new zoom
factor takes effect, egui does not use the screen_rect it is given: it scales the screen it had before, which is
10,000 pixels a side in a new context. So the canvas asks the render worker for a frame of about 10,000 × 10,000
pixels. When the worker finishes that frame before the next pass, uploading it exceeds the test's 8,192 pixel texture
limit.
Whether it fails depends on how fast the worker is. Run alone on this machine it fails every time. In a run of the whole
workspace, with every core busy, the frame is not ready in time and the test passes, which may be why CI doesn't see
it.
The test now spends that first pass on nothing, so the canvas's first frame has the window's size. canvas/tests_ui_scaling.rs already treats its first frames this way ("The first frames set the UI zoom and fit the
artboard").
The test expects the included file's path as it built it from std::env::temp_dir(). The report names the file as
the script host resolved it, through the links in its path, and on macOS /var is a link to /private/var. The test
now expects the resolved path (std::fs::canonicalize). On Linux the two are the same.
How it was tested
Before: each test alone (cargo nextest run -p vectorcraft-ui-egui --lib <name>) failed on every run, on main
with no other change.
After: the two tests passed 21 runs in a row.
No test was added: these are the tests.
On this branch, on main at 1e4e3534f: clippy, the workspace tests (cargo nextest run --workspace --lib --bins --tests: 21,162 passed, 20 skipped), the doctests, no-bundled-fonts, pdf-deps, assets, brands, cursors, i18n-report,
ui-commands and layers pass.
cargo xtask ci as a whole does not pass on main at 1e4e3534f, with or without this change, in two steps this
doesn't touch: fmt (crates/svg/src/lib.rs, which fmt: format crates/svg/src/lib.rs #7400 and Fix main CI after the craft-libs migration (fmt, wasm) #7407 format) and wasm (cargo check --target wasm32-unknown-unknown stops at "specification vectorcraft-geom is ambiguous": Cargo.lock now holds vectorcraft-geom 0.24.1 from the workspace and 0.18.0 from a git dependency).
I did not check whether the app itself asks for a frame that large at startup when UI Scaling is not 100%.
Checklist
cargo xtask ci passes (fmt, clippy, tests, assets, brands, layers, wasm). Not on main as it is now: see above.
No panics in shipped code: no unwrap(), expect(), panic!, unreachable!, todo! or unimplemented! outside tests, and no unchecked indexing on data from files, parameters or
messages. Errors are returned as Result and shown to the user
(why and how).
Clean-room: nothing copied from Adobe products or GPL/AGPL code (AGENTS.md).
Every new asset has a row in ASSETS.md.
Summary by CodeRabbit
Tests
Updated canvas scaling tests to initialize rendering with the intended screen dimensions, improving validation of scaling behavior.
Adjusted automation checks to compare normalized file paths, making tests more reliable across operating systems that report equivalent paths in different formats.
These changes improve test consistency and do not alter user-facing app behavior.
tiled_documents_fit_their_panes_at_every_ui_scaling drew its first canvas
frame in the pass where the UI zoom takes effect. egui sizes that pass from
the screen it had before, 10,000 pixels a side in a new context, so the
canvas asked the render worker for a frame of that size; when the worker
finished it before the next frame, the upload exceeded the test's 8,192
pixel texture limit. The test now spends that pass on nothing.
ui_inspect_script_report_leaves_out_files_outside_the_read_root expected
the included file's path as the test built it. The report names it as the
script host resolved it, through the links in its path, and macOS keeps the
temporary folder behind /var, a link to /private/var. The test now expects
the resolved path.
No actionable comments were generated in the recent review.
Walkthrough
Two UI tests change their setup or assertions. The canvas scaling test adds a pass at the target screen size before rendering. The script-report test compares canonicalized paths for the included file.
Changes: Canvas scaling test
Layer / File(s)
Summary
Prepare the scaling test crates/ui-egui/src/canvas/panes/tests.rs
The test runs an empty egui pass at the target screen size and clears its texture delta before rendering the canvas.
Automation script path test
Layer / File(s)
Summary
Check the reported script path crates/ui-egui/src/tests/automation.rs
The test compares canonicalized paths for the included file. Comments note platform-specific path differences.
This change only adjusts two desktop UI tests to make them stable on fast macOS machines and across platform path representations. It does not change production behavior, so the merge risk is minimal.

Explanation
The title names the change in the two tests and the platform, but it does not say what was changed. It is specific enough to be related to the changeset. The title is partially related: the changeset fixes two tests that fail on macOS, and the title says the tests pass on a fast Mac, which describes the symptom rather than the fix. The title is clear and not vague.
Full details: Description check
Explanation
The description follows the template. It has the 'What and why' section, which explains the two test failures, their causes, and the fixes. It has the 'How it was tested' section, which lists the before and after runs, the workspace test results, and the CI failures on main that the change does not touch. The Checklist is present. The first checklist item is left unchecked and the author explains why. The other items are checked. The description is thorough and complete.

- Around line 1200-1201: Normalize the canonicalized expected path in the
automation test before comparing it with person["scriptReport"]["file"],
matching the display form used by the include loader. Use
vectorcraft_engine::cmd::findfiles::plain if that module is reachable from the
ui-egui test crate; otherwise establish the accessible equivalent that applies
the same normalization. Preserve unchanged behavior for non-Windows paths.

Thanks, both diagnoses make sense. One change for the second test: on Windows std::fs::canonicalize returns a verbatim \?\C:\… path, while the report shows the plain one, so the new expectation would fail there. Comparing both sides canonicalized works everywhere, e.g.
let reported = person["scriptReport"]["file"].as_str().unwrap();assert_eq!(std::fs::canonicalize(reported).unwrap(), std::fs::canonicalize(base.join("outside/bad.jsxinc")).unwrap(),"{person}");
…iles
The expectation added in the previous commit wrote the included file's
path the way std::fs::canonicalize gives it. On Windows that path starts
with \\?\, which the report leaves off, so the test would fail there.
Both paths are now canonicalized before they are compared.
Thanks, good catch. Done in 17814d9: both paths are canonicalized before they are compared, as you suggested. This also covers CodeRabbit's comment on the same lines.
On macOS the test passes, and it fails when the expected path points at another file in the same folder. I haven't been able to run it on Windows.
