Add Comprehensive Test Suite for InputWidget Classes

Overview

This PR adds a comprehensive test suite for all InputWidget classes in the Chainlit backend, ensuring robust coverage of widget initialization, validation, and serialization across all widget types.

Changes

New Test File

• tests/test_input_widget.py - Complete test coverage for all InputWidget types

Test Coverage

Base InputWidget Validation (TestInputWidgetBase)

• Validation that all widgets require both id and label
• Error handling for missing required fields

Widget Types Tested

1. Switch Widget (TestSwitchWidget)

• Boolean toggle initialization
• Initial value configuration
• Tooltip and description support
• Disabled state handling
• Serialization to dictionary

2. Slider Widget (TestSliderWidget)

• Numeric range configuration (min, max, step)
• Initial value setting
• Custom range validation
• Serialization with all parameters

3. Select Widget (TestSelectWidget)

• Initialization with values list
• Initialization with items dictionary
• Initial selection via initial_index
• Initial selection via initial_value
• Validation: requires either values or items
• Validation: cannot have both values and items
• Validation: initial_index requires values
• Proper items transformation and serialization

4. TextInput Widget (TestTextInputWidget)

• Single-line and multiline modes
• Initial value and placeholder text
• Text input configuration
• Serialization with all options

5. NumberInput Widget (TestNumberInputWidget)

• Numeric input initialization
• Initial value and placeholder
• Float number support
• Serialization

6. Tags Widget (TestTagsWidget)

• Array of strings input
• Initial tags configuration
• Available values list
• Serialization

7. MultiSelect Widget (TestMultiSelectWidget)

• Multiple selection with values list
• Multiple selection with items dictionary
• Initial selection array
• Validation: requires either values or items
• Validation: cannot have both values and items
• Items transformation and serialization

8. Checkbox Widget (TestCheckboxWidget)

• Boolean checkbox initialization
• Initial checked state
• Tooltip and description
• Serialization

9. RadioGroup Widget (TestRadioGroupWidget)

• Radio button group with values list
• Radio button group with items dictionary
• Initial selection via initial_index
• Initial selection via initial_value
• Validation: requires either values or items
• Validation: cannot have both values and items
• Validation: initial_index requires values
• Serialization with items array

10. Tab Widget (TestTabWidget)

• Tab container initialization
• Tab with nested input widgets
• Empty tab handling
• Serialization with nested inputs

Test Statistics

• Total Tests: 75+
• Test Classes: 11
• Widget Types Covered: 10
• Coverage Areas:
  • Widget initialization and defaults
  • Validation and error handling
  • Serialization (to_dict())
  • Common fields (tooltip, description, disabled)
  • Type-specific configurations
  • Edge cases and complex scenarios

Testing Approach

• Pure unit tests (no async context needed for InputWidgets)
• Comprehensive validation error testing
• All widget types tested independently
• Edge cases and complex scenarios covered
• Consistent testing patterns across all widget types
