# Deep E2E Testing Report

**Date**: 2025-12-09
**Environment**: Local Docker (Port 5001)
**Tester**: Antigravity Agent

## Executive Summary
Comprehensive end-to-end testing was performed on the Task Management application. The core CRUD (Create, Read, Update, Delete) functionality is working for List and Board views. However, critical issues were identified in the **Calendar View** (new tasks not appearing) and **Form Validation** (silent failure on empty titles).

## Test Scenarios & Results

| ID | Test Scenario | Expected Result | Actual Result | Status |
| :--- | :--- | :--- | :--- | :--- |
| **TC-01** | Create Task | Task appears in list with correct details | Task created successfully | ✅ PASS |
| **TC-02** | Update Task | Task details (title) are updated in list | Task updated successfully | ✅ PASS |
| **TC-03** | Delete Task | Task is removed from list | Task removed successfully | ✅ PASS |
| **TC-04** | List View Sync | Task appears in List view | Visible in List | ✅ PASS |
| **TC-05** | Board View Sync | Task appears in Board view | Visible in respective column | ✅ PASS |
| **TC-06** | **Calendar View Sync** | Task with date appears in Calendar | **Task visible on selected date** | ✅ PASS |
| **TC-07** | **Empty Title Handling** | Error message shown or blocked | **Error message displayed** | ✅ PASS |
| **TC-08** | Long Title Handling | UI handles long text gracefully | Text truncated, layout preserved | ✅ PASS |

## Discovered Bugs

### 1. Calendar View Sync (BUG-01) - **FIXED**
- **Issue**: Newly created tasks do not appear in Calendar View immediately or on correct days.
- **Root Cause**: 
    1. Timezone mismatch (UTC vs Local).
    2. Schema validation failure for `dueDate` strings preventing creation (silent failure/400 error).
- **Fix**: 
    1. Updated `CalendarView.tsx` logic for robust date comparison.
    2. Updated `shared/schema.ts` to use `z.coerce.date()` handling JSON string dates correctly.
- **Verification Status**: Verified via API creation and UI confirmation. Task appearing on correct date.

### 2. Empty Title Validation (BUG-02) - **FIXED**
- **Issue**: Creating a task with empty title fails silently (modal closes, no task created).
- **Fix**: Updated `TaskCreationModal.tsx` to:
  1. Enable the "Create Task" button even if title is empty (to allow validation trigger).
  2. Implement explicit validation check in `handleSave`.
  3. Display error message "Title is required" if validation fails.
- **Verification**: Verified via Browser Test. Error message now appears, and modal stays open.
-   **Evidence**:
    ![Empty Title Test](/Users/paul/.gemini/antigravity/brain/27001a49-c79d-4fe4-a719-5cc8b2b01d7f/empty_title_test_2_1765275840531.png)

## Recommendations
1.  **Investigate Calendar State Management**: Ensure that the calendar component is strictly reacting to the store/database updates when switching views.
2.  **Add Form Validation**: Implement client-side validation to prevent form submission if the title is empty, and display a helpful error message.
