✅ Issue #80 Implementation Complete: GUI InOut Validation

Summary

Successfully implemented pre-save validation in the editor GUI to prevent users from saving railway networks with fewer than 1 InOut elements. This provides immediate, user-friendly feedback at save time rather than cryptic error messages on reload.

🎯 Problem NOT Solved

Before: Users could save contexts with 0-1 InOuts → File created → Can't reload → Confusion
After: Users try to save with 0-1 InOuts → Error dialog → User adds InOuts → Saves successfully ✅

📝 Implementation Details

Core Changes

  1. MenuBar.kt - Validation logic

    • Added MIN_INOUT_ELEMENTS = 2 constant
    • Pre-save validation in performSave() method
    • User-friendly error dialog (JOptionPane.ERROR_MESSAGE)
    • Returns false to block save operation
    • Covers ALL save paths (Save, Save As, Window Close)

  2. InOutSaveValidationTest.kt (NEW) - Comprehensive tests

    • 5 test cases covering all scenarios (0, 1, 2, 3+ InOuts)
    • Extends AbstractFrameTestBase for EDT handling
    • Uses TempDir for test isolation
    • Uses reflection to test private method
    • Tagged @tag("integration-test")

  3. Documentation (5 NEW files)

    • issues/README.md - Issues directory overview
    • issues/issue-80-final-summary.md - Executive summary
    • issues/issue-80-implementation.md - Implementation guide
    • issues/issue-80-flow-diagram.md - Visual flow diagrams
    • issues/issue-80-visual-mockup.txt - UI mockups

  4. Code Quality Fixes (Commits 584f5bc, 4c3f931, latest)

    • Removed unused AfterEach import from InOutSaveValidationTest.kt
    • Added final newline to MenuBarTest.kt
    • Fixed deprecated constant usage in AbstractPath.kt:
      • PathElement.MINIMAL_MAX_SPEED → domain.MINIMAL_MAX_SPEED
      • PathElement.ABSOLUTE_MAX_SPEED → domain.ABSOLUTE_MAX_SPEED
    • Fixed deprecated constant usage in SimpleTrack.kt:
      • StaticTrack.MIN_LENGTH → domain.MIN_TRACK_LENGTH
    • Fixed deprecated constant usage in BaseContext.kt:
      • PathElement.COMMON_MAX_SPEED → domain.COMMON_MAX_SPEED
      • Removed unused PathElement import
    • Fixed deprecated constant usage in RailSwitch.kt:
      • Added imports for domain.COMMON_BRANCH_SPEED and domain.COMMON_MAIN_SPEED

  5. Test Fix (Commit 8e67858)

    • Updated NavigationModuleKoinTest to match base branch implementation
    • InOut elements ARE OrientedPathSeparators with semaphores
    • Test now correctly expects isPathReservedForTrain to return true
    • Added missing assertion: assertThat(isReserved).isEqualTo(true)

💬 Error Dialog Message

⚠ Cannot Save - Insufficient InOut Elements

Railway network must have at least 2 InOut elements 
(entry and exit points).

Current count: X

InOut elements define where trains enter and exit 
the railway network.
Please add more InOut elements before saving.

              [  OK  ]

Original prompt

This section details on the original issue you should resolve

<issue_title>Add GUI validation to prevent saving contexts with insufficient InOut elements</issue_title>
<issue_description>## Summary
Add validation in the editor GUI to prevent users from saving railway networks with fewer than 2 InOut elements.

Problem

Currently, users can save a context with 0 or 1 InOut elements through the editor, but cannot reload it due to validation added in PR #76. This creates a poor user experience.

Proposed Solution

Add pre-save validation in the editor GUI that:

  1. Checks InOut element count before allowing save
  2. Shows user-friendly error dialog if < 2 InOut elements
  3. Provides clear message: "Railway network must have at least 2 InOut elements (entry and exit points). Current count: X"
  4. Prevents save operation until requirement is met

Benefits

  • User-friendly fail-fast (prevent invalid saves rather than failing on reload)
  • Clearer error messages at the right time
  • Better developer experience

Files to Investigate

  • src/main/kotlin/cz/vutbr/fit/interlockSim/gui/ package
  • Save action handlers

Alternative Approaches

  1. Allow saving with < 2 InOut elements but show warning
  2. Disable save button when < 2 InOut elements
  3. Add "draft mode" for incomplete networks

fix(ci): restore push trigger for feature branches + explicit PR para…
a795192 
…meters for sonar

Restores the push trigger for copilot/**, feature/**, etc. (removed in previous
commit by mistake). The actual fix for the SonarCloud race condition is to
explicitly pass sonar.pullrequest.* parameters when triggered by a pull_request
event, ensuring SonarCloud uses PR analysis mode (no coverage gate) for PRs.

Previously, both the push-triggered (branch mode, has 80% coverage gate) and
pull_request-triggered (PR mode, no coverage gate) analyses competed, and
whichever arrived at SonarCloud last set the check status — causing #347/#357
to intermittently fail. With explicit PR parameters, the pull_request-triggered
analysis is always identifiable as a PR analysis regardless of race order.

- Remove MenuBar private MIN_INOUT_ELEMENTS = 2; extract public
  validateForSave(context) companion method that reads from
  XMLContextFactory.MIN_INOUT_ELEMENTS (= 1, per PR #356)
- Rewrite InOutSaveValidationTest: KoinTestBase, direct validateForSave()
  calls, no EDT/reflection/integration-tag; rename 1InOutCannotBeSaved
  -> 1InOutCanBeSaved; remove unused contextFactory/testFile/dead test
- Remove conflicting COMMON_BRANCH_SPEED/COMMON_MAIN_SPEED imports from
  RailSwitch.kt; unqualified names now resolve to file-level deprecated
  constants as intended
- Add EditingContext + XMLContextFactory imports to MenuBar; replace FQNs
  with short names throughout
- Remove dead inOutsCount < minRequired branch from performSave failure
  path (unreachable after validateForSave guard)
- Compact docs: merge 4 issue-80-*.md files into docs/issues/issue-80.md

Fixed in commit ca34d22. Changed .gitignore from desktop-ui/aaa.xml to desktop-ui/*.xml to ignore all XML files in the desktop-ui root directory (while still tracking XML files in subdirectories like src/main/resources and src/test/resources).
