Detailed Test Results

✅ Test 4.3: Reset Module (Priority 1)

Command: tito module reset 04 --force

Initial Result: ❌ FAILED

• Module reset looked for files in modules/ instead of src/
• Used short filename (losses.py) instead of full (04_losses.py)

Bug Found: Bug #1 - Reset command uses wrong directory path (HIGH severity)

Fix Applied:

• Updated tito/core/config.py line 50: modules/ → src/
• Updated module_reset.py lines 248, 307: short name → full module name

Final Result: ✅ PASS

• Backup created successfully (.tito/backups/04_losses_TIMESTAMP/)
• Export removed (tinytorch/core/losses.py deleted)
• Source restored from git HEAD
• Progress tracking updated (4/21 → 3/21)
• Module status changed from "✅ Done" to "🚀 Working"

Success Criteria Met:

• ✅ Creates backup before resetting
• ✅ Removes from completed list
• ✅ Unexports from tinytorch/
• ✅ Restores source files to git HEAD
• ✅ Can start module again fresh

Side Effect Discovered: Bug #2 - Reset doesn't update __init__.py imports (HIGH severity)

---

✅ Test 3.1: Complete Module with Failing Tests (Priority 1)

Command: tito module complete 02 (with intentionally broken test)

Test Modification:

# Intentionally changed assertion to fail:
assert np.allclose(result.data, [0.99])  # Should be [0.5]

Result: ✅ PASS - Test failure handled correctly

Output:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

 Step 1/3: Running Tests

Errors:
AssertionError: sigmoid(0) should be 0.5, got [0.5]

   ❌ Tests failed for 02_activations
   💡 Fix the issues and try again

Verification:

• Module 02 remained "✅ Done" (not re-marked)
• Export did NOT happen
• Progress tracking did NOT update
• Exit code: 1 (error)

Success Criteria Met:

• ✅ Tests fail with error message
• ✅ Shows "❌ Tests failed"
• ✅ Suggests "Fix the issues and try again"
• ✅ Module NOT marked as complete
• ✅ Export does NOT happen
• ✅ Can run complete again after fixes

✅ Test 3.2: Fix Tests and Re-Complete (Priority 1)

Command: tito module complete 02 (with fixed test)

Result: ✅ PASS - Module completed successfully

Output:

                        3 modules until unlock

💡 What to do:
   1. Work in Jupyter Lab (opening now...)
   2. Build your implementation
   3. Run: tito module complete 05

Success Criteria Met:

• ✅ Prerequisites check passes (01-04 completed)

Output:

🔄 Resuming Module 05: 05_autograd
💡 Continue your work, then run:
   tito module complete 05

Success Criteria Met:

• ✅ Resumes module 05 (last worked)
• ✅ Opens Jupyter Lab
• ✅ Shows clear message about what to do next

---

✅ Test 4.2: Resume Specific Module (Priority 2)

Command: tito module resume 04

⚠️ Test 5.2: Complete Without Prerequisites (Priority 2)

Command: tito module complete 06 (when module 05 not complete)

Result: ⚠️ PASS with Bug - Command runs but silently fails to mark complete

Bug Found: Bug #3 - Complete doesn't check prerequisites (MEDIUM severity)

Observation:

• Tests run (wastes resources)
• Export happens (unnecessary work)
• Module not marked complete (correct outcome, but inefficient)
• No clear error message shown to user

What Should Happen: Should fail early with prerequisite check, like start command does:

╭────────────────────────────── 🔒 Module Locked ──────────────────────────────╮
│ Module 06: 06_optimizers is locked                                           │
│ Complete the prerequisites first before attempting to complete this module.   │
╰──────────────────────────────────────────────────────────────────────────────╯

Bugs Found

🔴 Bug #1: Reset Command Uses Wrong Directory Path (HIGH)

Status: ✅ FIXED

• Files Changed: tito/core/config.py, tito/commands/module_reset.py
• Verification: Reset command now works correctly

🔴 Bug #2: Reset Doesn't Update init.py Imports (HIGH)

Status: 🔴 OPEN - Needs Fix

• Impact: Resetting any module breaks imports for all other modules
• Workaround: Manually comment out imports in tinytorch/__init__.py
• Fix Required: Add update_init_imports() method to module_reset.py

🔴 Bug #3: Complete Command Doesn't Check Prerequisites (MEDIUM)

Status: 🔴 OPEN - Needs Fix

• Impact: Wastes resources running tests/export for locked modules
• Fix Required: Add prerequisite check at start of complete_module() method
• Inconsistency: start command checks prerequisites, but complete doesn't
