Common Web UI Component Test Scenarios and Checklist

Navigation Bar Testing

Check if navigation is intuitive and clearly reflects main system functions.

Verify consistency of navigation style with other menus and displays.

Ensure navigation links and URL parameters lead to correct pages.

Test tab switching, hierarchical back‑navigation, and content consistency across different navigation bars.

Assess interaction effects between navigation modules and other page components.

Input Field Testing

Validate character length boundaries (min‑1, min, max, max+1, overly long).

Test special characters (e.g., &, single quotes, spaces) for proper handling.

Check automatic trimming of leading/trailing spaces.

Confirm error prompts appear when saving empty inputs.

Test injection strings (null, JavaScript, HTML) for security.

For numeric fields, verify handling of negatives, fractions, non‑numeric input, zero, scientific notation, alphanumeric mixes, hexadecimal, octal, currency formats, and decimal precision.

Ensure logical constraints such as uniqueness of names and correct focus behavior.

Validate auto‑fill functionality and its data accuracy.

Button Testing

Confirm button is clickable and any associated dialogs appear as expected.

Check visual states: normal, hover, pressed.

Verify functional outcomes (database storage, inter‑module interaction).

Test activation via Enter key and navigation via Tab key.

Assess single‑click restrictions and subsequent behavior.

Determine whether error messages are generated client‑side or server‑side and displayed correctly.

Validate cancel button closes pages and returns to the appropriate view.

Dropdown (Select) Testing

Validate default display (e.g., "Please select", all items, pre‑selected item).

Check item ordering, scrolling behavior, and visual integrity across browsers.

Test handling of overflow items (scrollbars, pagination).

Ensure dropdown collapses when clicking outside.

Verify data persistence and correct mapping between stored values and displayed text.

Assess cascading selections (e.g., province → city) and combined filter functionality.

Table/List Testing

Check table dimensions, scrollbars, and responsive layout.

Validate header help information (tooltips, icons).

Verify cell content diversity and correctness.

Test empty‑state display, pagination, sorting, and auxiliary actions (add, edit, delete, download).

Confirm select‑all functionality and interaction with pagination and filters.

Assess editing persistence across pages and correct data refresh after operations.

Radio and Checkbox Testing

Radio: ensure default selection, exclusive selection, functional outcome, and correct value transmission.

Checkbox: test none selected, all selected, partial selection, select‑all/none features, and combined UI effects.

Dual List Box (Left‑Right Selector) Testing

Validate left‑side data display, empty state, scrolling, and expand/collapse behavior.

Check transfer of items to the right side, gray‑out handling, and correct data after addition or removal.

Verify count indicators and performance with large data sets.

Time Picker Testing

Confirm date selection accuracy (year, month, day).

Validate start‑end time logic (start ≤ end).

Enforce date range limits (e.g., year 1900‑present).

Check cross‑browser/resolution rendering.

Test shortcut keys and correct value transmission, including edge cases like inclusion of the current day.

Ensure time picker retains value when interacting with other filters.
