Web loading lifecycle progress transition refactor - #895
Conversation
Consolidates engine configuration by merging a custom onProgress telemetry hook that logs assembly transfer percent, and initializes Engine with the merged config. Updates the loading UI comment to mention accessibility and normalizes multiple button handler assignments by removing inline comments/formatting. Small refactor/cleanup in custom_shell.html to add telemetry and improve clarity.
tests/splash_transition_flow_test.py: update comment to include GEOMETRY and add assertions verifying canvas_element.bounding_box() is not None and that its width/height are > 0. Ensures the rendering canvas is actually laid out (detects headless/renderer failures) during the splash transition test.
Parse 'Telemetry - Assembly Transfer: X%' marks using regex and assert their presence, bounds (0–100), and monotonic progression. Added re import, improved test docstring and comments, and strengthened canvas/title assertion messages. Added invariant check that window.godotInitialized remains true after overlay teardown. Miscellaneous readability tweaks. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Hey - I've left some high level feedback:
- The
onProgresstelemetry hook currently logs every progress update toconsole, which may be noisy in production; consider gating this behind a debug flag or sampling to reduce log volume while keeping useful metrics. - The monotonicity assertion for
progress_valuesuses strict sorting equality, which will fail on repeated values (e.g., 50,50,75); if equal consecutive readings are acceptable, relax this to a non-decreasing check (e.g., comparing each value to the previous).

Reflowed long docstrings/comments and split artifact listing for readability. Tightened logging/assert messages and multiline formatting for regex and function calls. Capture diagnostic paths into variables (screenshot/log/html) before writing. Handle CDP coverage response safely by extracting the "result" key. Overall non-functional cleanup and small robustness improvements to error handling and telemetry parsing.
Add ARIA state and focus transfer to the loading flow: mark the loading div role="status" with aria-live="polite" and aria-busy="true"; when the engine starts hide the loading UI and update aria-hidden="true" and aria-busy="false"; move keyboard focus to the canvas so screen-reader and keyboard users can interact with the game immediately. Minor comment updates and retained error fallback. Improves accessibility and UX during boot.

Learning: When writing/adjusting tests that assert SkyLockAssault log output for difficulty (and other float settings), expect the decimal point to be preserved (e.g., logs like "setting 'difficulty' updated to: 1.0"). Do not use regexes that fail on floats due to the decimal point (e.g., patterns with a negative lookahead that assumes digits contain no '.'), since they will not match "1.0". Instead, use a simple substring check for the expected log prefix/value, or use a float-aware regex (e.g., matching `\d+(?:\.\d+)?`) / parse the logged value as a float before asserting.

Replace brittle manual brace-matching in _extract_on_progress_function_source with a regex that captures the full onProgress function (handles nested braces). Simplifies error handling and returns the function source verbatim.
Save a timestamped screenshot when the splash transition test fails and include it alongside console logs and the DOM HTML snapshot. Updates _save_failure_artifacts docstring and adds PNG, TXT, and HTML outputs to ARTIFACTS_DIR for better diagnostics.

- The Playwright unit tests currently regex-extract the
onProgressfunction source fromcustom_shell.html; consider moving this callback into a dedicated JS module or config file that can be imported directly to avoid brittle parsing and to keep the shell markup and test code loosely coupled. - The telemetry
onProgresshook only guards againsttotal <= 0; you may want to explicitly handle unexpected values (e.g., negativecurrent/totalorcurrent > total) to prevent misleading percentage logs in edge cases.

</code_context>
<issue_to_address>
**suggestion (bug_risk):** Consider updating the ARIA role/live region when the loading state completes.
`aria-hidden` and `aria-busy` are updated when the game starts, but the element still has `role="status"` and `aria-live="polite"` while hidden. Hidden live regions can behave unexpectedly in some screen readers. Consider removing or neutralizing these live-region attributes after loading (e.g., unset `aria-live`/`role`) or move them to a child node you can remove entirely once the status message is no longer needed.
Suggested implementation:
```
<!-- Loading screen with progress bar (updated for better ARIA labeling) -->
<div id="loading" aria-busy="true">
<!-- Live region limited to this child so it can be removed/neutralized after loading -->
<div id="loading-status" role="status" aria-live="polite">
```
1. Ensure the new `#loading-status` element is closed appropriately near the end of the loading markup, before the closing `</div>` for `#loading`, e.g.:
- Add `</div>` to close `#loading-status` just before the existing closing `</div>` for `#loading`.
2. When loading completes (where you currently clear `aria-busy` / hide `#loading`), also neutralize or remove the live region:
- Either remove the child entirely:
`document.getElementById('loading-status')?.remove();`
- Or unset its live-region attributes:
```js
const status = document.getElementById('loading-status');
if (status) {
status.removeAttribute('role');
status.removeAttribute('aria-live');
}
```
3. If any code is currently querying `#loading` expecting the live-region attributes (e.g., tests or analytics), update it to target `#loading-status` instead.

+ engine.startGame().then(() => {
</code_context>
<issue_to_address>
**suggestion (bug_risk):** Align ARIA/loading state updates between success and failure paths.
In the error path the `#loading` element remains visible with `aria-busy="true"` and `role="status"`, so assistive tech may think loading never finishes. Update the loading element in the `catch` branch as well (e.g., set `aria-busy="false"`, hide it, or present an explicit error status), ideally via a shared helper so success/failure paths stay consistent.
Suggested implementation:
```
// Initialize engine instance with customConfig
var engine = new Engine(customConfig);
// Shared helper to keep ARIA/loading state consistent across success/failure
function updateLoadingUI(isError, errorMessage) {
var loadingDiv = document.getElementById('loading');
if (!loadingDiv) {
return;
}
// Loading is no longer in-progress in both cases
loadingDiv.setAttribute('aria-busy', 'false');
if (isError) {
// Keep the element visible as an explicit error status for assistive tech
loadingDiv.style.display = 'block';
loadingDiv.removeAttribute('aria-hidden');
loadingDiv.setAttribute('role', 'status');
if (errorMessage) {
loadingDiv.textContent = errorMessage;
}
} else {
// Hide loading UI on success and mark it as not relevant
loadingDiv.style.display = 'none';
loadingDiv.setAttribute('aria-hidden', 'true');
}
}
// Start Godot engine (async for stability)
engine.startGame()
.then(() => {
console.log("Godot engine started successfully!");
// Hide the loading UI, update ARIA state, and transfer focus to the game
updateLoadingUI(false);
})
.catch((error) => {
console.error("Failed to start Godot engine:", error);
// Ensure loading state is finalized for assistive tech and surface an explicit error
updateLoadingUI(true, "Failed to start the game. Please reload the page or try again later.");
}
);
```
1. If there is existing logic elsewhere that sets `role="status"` or the text of `#loading`, you may want to harmonize the error message text or move that logic into `updateLoadingUI` to avoid duplication.
2. If your loading UI uses inner HTML (e.g., spinner markup), consider rendering the error message in a dedicated child element instead of replacing `textContent` on the root `#loading` element.

**suggestion:** Make onProgress function extraction more robust and use the existing marker constant.
The `_extract_on_progress_function_source` regex is tightly coupled to the current `custom_shell.html` layout, so small, non‑semantic changes (comments, nesting, spacing) could cause false test failures. Since `_ON_PROGRESS_MARKER` is defined but unused, consider using it to locate the callback in the file and then extract the function from that anchor, or relax the regex to tolerate common formatting variations. This will make the tests less brittle and more focused on behavior than exact text structure.
```suggestion
def _extract_on_progress_function_source() -> str:
"""Extracts onProgress telemetry callback verbatim from custom_shell.html.
Uses the `_ON_PROGRESS_MARKER` anchor to locate the callback and then
parses out the function body by matching balanced braces. This keeps the

### Comment 4
<location path="tests/splash_transition_flow_test.py" line_range="221-230" />
<code_context>
+def _save_failure_artifacts(
</code_context>
<issue_to_address>
**suggestion:** Harden artifact capture against failures when the page is already closed or in an error state.
`_save_failure_artifacts` is great for debugging, but `page.screenshot()` / `page.content()` can raise if the page is already closed or in an error state (e.g., crash). That can hide the original assertion failure. Consider wrapping each artifact capture (screenshot, logs, DOM snapshot) in its own `try/except` and logging best-effort results so diagnostics are preserved without obscuring the primary error.
Suggested implementation:
```python
def _save_failure_artifacts(
page: Page, logs: list[dict[str, str]], page_errors: list[str]
) -> None:
"""Captures screenshot, logs, and DOM snapshot to ARTIFACTS_DIR on error."""
timestamp = int(time.time())
# 1. Screenshot (best-effort; don't mask primary failure)
screenshot_path = (
ARTIFACTS_DIR / f"test_splash_failure_screenshot_{timestamp}.png"
)
try:
page.screenshot(path=str(screenshot_path))
except Exception: # best-effort only; page may already be closed/crashed
logging.getLogger(__name__).warning(
"Failed to capture failure screenshot at %s", screenshot_path, exc_info=True
)
# 2. Logs (best-effort)
logs_path = ARTIFACTS_DIR / f"test_splash_failure_logs_{timestamp}.json"
try:
with logs_path.open("w", encoding="utf-8") as fp:
json.dump(
{
"page_errors": page_errors,
"logs": logs,
},
fp,
indent=2,
ensure_ascii=False,
)
except Exception:
logging.getLogger(__name__).warning(
"Failed to write failure logs to %s", logs_path, exc_info=True
)
# 3. DOM snapshot (best-effort; may fail if page is closed/crashed)
dom_snapshot_path = (
ARTIFACTS_DIR / f"test_splash_failure_dom_snapshot_{timestamp}.html"
)
try:
dom_content = page.content()
with dom_snapshot_path.open("w", encoding="utf-8") as fp:
fp.write(dom_content)
except Exception:
logging.getLogger(__name__).warning(
"Failed to capture DOM snapshot at %s", dom_snapshot_path, exc_info=True
)
```
To fully support these changes, you should also:
1. Ensure `import logging` and `import json` are present at the top of `tests/splash_transition_flow_test.py`. If they are not, add them alongside the other imports.
2. Confirm that `ARTIFACTS_DIR` is created before `_save_failure_artifacts` is called (e.g., `ARTIFACTS_DIR.mkdir(parents=True, exist_ok=True)`), if this is not already guaranteed elsewhere.
