Pull request overview
This PR completes the E2E test refactoring initiative by introducing a shared test helpers module and converting all 12 E2E test files to use these utilities, eliminating significant code duplication. The PR also consolidates duplicate intro-screen tests by merging intro-screen-fix-verification.cy.ts into the main intro-screen.cy.ts file.
Changes:
- Created
cypress/support/test-helpers.tswith 26 reusable helper functions across 9 categories (setup, canvas verification, combat utilities, stance testing, bilingual text, assertions, training, performance, and navigation) - Refactored all 12 E2E test files to use shared helpers, reducing duplication by approximately 47%
- Deleted
intro-screen-fix-verification.cy.tsafter successfully merging its test case intointro-screen.cy.ts - Added comprehensive documentation:
cypress/E2E_TEST_ORGANIZATION.mdandcypress/E2E_TEST_OPTIMIZATION_SUMMARY.md

cypress/e2e/screens/combat-screen.cy.ts:92
- Incomplete refactoring: The call to
testAllTrigramStancesis immediately followed by old code that duplicates the stance testing logic. Lines 80-90 contain a for loop attempting to test stances, but this code is unreachable and uses undefined variables (stance,stanceNames). This appears to be leftover code from the refactoring that should have been removed.
cy.log(`Testing stance ${stance} (${stanceNames[stance - 1]})...`);
cy.get("body").type(stance.toString());
// Wait for stance indicator to update using assertion instead of fixed wait
cy.get('[data-testid="player1-stance-indicator"]', { timeout: 2000 })
.should("exist")
.invoke("text")
.should("include", stanceNames[stance - 1]);
cy.log(`β
Stance ${stance} input processed`);
}
cy.log("β
All 8 trigram stances tested");
cypress/e2e/combat/injury-movement.cy.ts:82
- Incomplete refactoring: After calling
executeCombatAttacks(10, 800)to execute 10 attacks, the old loop code (lines 75-82) is still present. This includes manual attack execution withcy.get("body").type(" ")andcy.wait(600)which duplicates whatexecuteCombatAttacksalready does. The old loop also references undefined variablei. This leftover code should be removed.
cy.get("body").type(" ");
cy.wait(600);
// Verify rendering continues
if (i % 3 === 0) {
cy.verifyThreeJSRendering({ timeout: 1000, minPixelChange: 10 });
}
}
cypress/e2e/screens/trauma-visualization.cy.ts:63
- Incomplete refactoring: The helper
executeCombatAttacksis imported but not used. Lines 50-63 contain a manual for loop that executes 5 attacks, which could be replaced withexecuteCombatAttacks(5, 400). This would be more consistent with the refactoring goals and reduce code duplication.
for (let i = 1; i <= 5; i++) {
cy.log(`Strike ${i}/5 - Hitting torso`);
// Press attack button (space or click attack button)
cy.get("body").type(" ");
// Wait for attack animation

Documentation inconsistency: This section lists 6 files as "Remaining Work (Optional Phase 3)" but these files are actually refactored in this PR (as shown in the diffs). The documentation should clarify that this PR completes the refactoring of all 12 files (100% coverage), not just 50%. Consider updating this section to reflect that these files have been completed rather than listing them as remaining work.

The inline comment states that cleanupThreeJSResources() disposes geometries, materials, and textures. However, the actual implementation only requests garbage collection - it does not directly dispose Three.js resources. This comment should be updated to accurately reflect what the function does, such as "Request garbage collection hint" or "Best-effort memory cleanup".

The "Benefits Delivered" section claims that "Three.js geometries, materials, and textures properly disposed", "WebGL contexts cleaned up", "Event listeners removed", and "Canvas elements cleared from memory" are accomplished by the implemented functions. However, the actual cleanupThreeJSResources() and forceMemoryCleanup() implementations only request garbage collection hints - they do not directly perform any of these cleanup operations. This creates misleading expectations about what the code actually does. Please update this section to accurately reflect that the functions provide best-effort garbage collection hints, and that application-specific cleanup logic would need to be implemented within the application for comprehensive resource disposal.

There was a problem hiding this comment.
The waitForTransition(300) call here is redundant. The next line (71-74) already waits for the stance indicator to update with a 2000ms timeout using .should("exist") and .should("include", stance.name). Cypress will automatically wait for these assertions to pass. The waitForTransition() call before the assertion doesn't add value and could be removed. The same issue exists on line 77 - calling waitForTransition() after the assertion is redundant since the assertion already verified the state updated.

Fixed in commit 7971824. Removed redundant waitForTransition() calls on lines 68 and 77. The stance indicator assertion already waits with a 2000ms timeout, making the additional waits unnecessary.

The changeStance() function uses a hardcoded cy.wait(300) instead of assertion-based waiting. This is inconsistent with the improvements made to testAllTrigramStances() which waits for the stance indicator to update. Consider updating this function to use the same assertion-based approach for consistency and reliability. The function should wait for the stance indicator to actually update rather than using a fixed delay.

Fixed in commit 7971824. changeStance() now uses assertion-based waiting: cy.get('[data-testid="player1-stance-indicator"]', { timeout: 1000 }).should('contain', stanceNames[stanceNumber - 1]) instead of hardcoded cy.wait(300), consistent with testAllTrigramStances().

The testAllTrigramStances() function uses a synchronous for loop with Cypress commands, which can lead to issues since Cypress commands are asynchronous and queued. While this may work in practice, it's not following Cypress best practices. Consider using Cypress._.times() similar to how executeCombatAttacks() was refactored, or document why the for loop pattern is acceptable here when it was avoided elsewhere.

The waitForTransition() function doesn't actually wait for a transition or animation to complete - it just verifies the body element is visible with a timeout. The documentation and function name are misleading. The implementation is just cy.get("body", { timeout: durationMs }).should("be.visible"), which will succeed immediately if the body is already visible. This doesn't provide any meaningful wait for animations or transitions to complete. Consider either implementing a proper transition wait (checking for animation completion, CSS transition end, etc.) or renaming to reflect what it actually does (e.g., ensureBodyVisible()).

There was a problem hiding this comment.
The documentation describes cleanupThreeJSResources() as disposing geometries, materials, and textures, removing canvas event listeners, and triggering application cleanup functions. However, the actual implementation in cypress/support/test-helpers.ts (lines 80-101) only requests garbage collection if available - it does NOT perform any of these cleanup actions. The function documentation in test-helpers.ts was correctly updated to reflect this, but this documentation file was not updated to match. Please update this section to accurately reflect that the function only provides a GC hint and does not directly dispose Three.js resources.

The executeRapidStanceChanges function uses cy.wait(delayMs) after each stance change, including the last one. This creates an unnecessary wait at the end. Consider using the same pattern as executeCombatAttacks (lines 214-217) which only waits between actions, not after the final one.

The comment "Enhanced cleanup to prevent memory leaks" is misleading and appears in all refactored test files. The cleanup utilities only request garbage collection hints and do NOT actually prevent memory leaks by disposing Three.js resources. Consider using more accurate wording like "Request garbage collection to assist memory cleanup" across all test files.

Fixed in commit d7ca817. Updated all test file comments from "Enhanced cleanup to prevent memory leaks" to "Request garbage collection to assist memory cleanup" for accurate description of what the utilities actually do.

The documentation claims this PR implements "memory leak prevention" and that the cleanup utilities "dispose Three.js resources," but the actual implementation only requests garbage collection hints and does NOT dispose Three.js geometries, materials, or textures.
The function comments in test-helpers.ts correctly state this limitation (lines 71-78), but the documentation files (E2E_TEST_IMPROVEMENTS.md, E2E_MEMORY_CLEANUP_COMPLETE.md) present these utilities as if they actually prevent memory leaks by disposing Three.js resources. This is misleading.
The documentation should clearly state that:
- These utilities only request GC hints from the browser (if available)
- Actual Three.js resource disposal must be implemented in the application code
- Memory leaks may still occur without proper application-level cleanup
- The "memory leak prevention" claim is aspirational, not guaranteed by these utilities alone
| Forces memory cleanup and garbage collection: | |
| - Clears large data structures | |
| - Requests browser garbage collection | |
| - Waits for cleanup to complete | |
| Provides a stronger best-effort GC hint and memory logging: | |
| - Invokes the same browser garbage collection hooks as `cleanupThreeJSResources()` (if available) | |
| - Can be combined with application-level hooks to clear large data structures before requesting GC | |
| - Does not itself dispose Three.js geometries, materials, textures, WebGL contexts, canvases, or DOM/event resources | |
| - Does not guarantee that memory will be reclaimed; leaks may still occur without proper application-level cleanup |

Fixed in commit d7ca817. Updated forceMemoryCleanup() documentation in E2E_TEST_IMPROVEMENTS.md to accurately state that it provides GC hints, doesn't directly dispose Three.js resources, and leaks may still occur without proper application-level cleanup.

The expected improvements table claims a 70% reduction in peak memory per test (from 338MB to less than 100MB), but this is unrealistic given that the cleanup utilities only request garbage collection and don't actually dispose Three.js resources.
Without proper Three.js resource disposal in the application code, these utilities cannot achieve the claimed memory improvements. The expectations should be adjusted to reflect what GC hints alone can realistically achieve, or the documentation should clarify that these improvements depend on implementing proper disposal logic in the application.
| > Note: The memory improvements described in this document (including any example percentage reductions) assume that the application code correctly disposes of Three.js resources (geometries, materials, textures, render targets, etc.) between tests. | |
| > The Cypress helpers (`cleanupThreeJSResources`, `forceMemoryCleanup`) primarily coordinate cleanup and provide garbage collection hints; on their own they cannot guarantee large reductions in peak memory usage if scene resources are never disposed. |

Fixed in commit d7ca817. Added disclaimer after the Expected Results table clarifying that memory improvements assume proper Three.js resource disposal in application code, and that the Cypress helpers alone cannot guarantee large memory reductions.

The koreanNames array is defined but never used in this function. It's only referenced in the cy.log statement at line 260, which could directly use the Korean name from the stanceNames array mapping if needed. Consider removing this unused variable or clarifying its purpose.

The waitForTransition function logs the wait message after the wait completes. While this is technically correct, it might be more intuitive to log before waiting (or both before and after) so that developers watching the test execution can see what's happening in real-time. Currently, the log appears only after the wait is done, which doesn't help with understanding delays during execution.
| cy.wait(durationMs); | |
| } | |
| cy.log(`β±οΈ Waited ${durationMs}ms for transition to complete`); | |
| // Log before waiting so test execution clearly shows the upcoming delay | |
| cy.log(`β±οΈ Waiting ${durationMs}ms for transition to complete`); | |
| cy.wait(durationMs); | |
| // Log after waiting to confirm the delay has finished | |
| cy.log(`β±οΈ Completed wait of ${durationMs}ms for transition to complete`); | |
| } |

Fixed in commit d7ca817. waitForTransition() now logs before starting the wait ("Waiting...") and after completion ("Completed...") so developers can see delays in real-time during test execution.

The comment says "Enhanced cleanup to prevent memory leaks" but this is misleading. The cleanup utilities only request garbage collection hints from the browser and do NOT actually prevent memory leaks by disposing Three.js resources.
A more accurate comment would be: "Request garbage collection to help free memory" or "Best-effort memory cleanup - actual Three.js disposal must be done by application code"

| // Best-effort memory cleanup: request garbage collection hints; actual Three.js disposal is handled by application code |

<issue_title>π Phase 3: Cypress Test Consolidation (Merge Duplicate intro-screen Tests)</issue_title>
<issue_description>## π― Objective
Consolidate duplicate Cypress E2E tests for intro-screen by merging two overlapping test files into a single comprehensive test suite, eliminating redundancy and improving maintainability.
π Background
Current State: Two Cypress test files exist for the intro screen with significant overlap, creating maintenance burden and redundant test execution.
From TASKS_LEFT.md Phase 3: Cypress Test Consolidation
cypress/e2e/screens/intro-screen.cy.ts(87 lines)cypress/e2e/screens/intro-screen-fix-verification.cy.ts(76 lines)Impact: Redundant tests increase CI time, create maintenance burden, and risk test drift between the two files.
