description: Detect all UI elements on screen using OmniParser

<!-- Generated from parse.mdx. DO NOT EDIT. -->

Overview

Parse the screen with OmniParser v2 to find all visible UI elements. TestDriver returns structured data. This includes element types, text content, interactivity levels, and bounding box coordinates.

This method examines all of the screen and returns each element that it finds. Use it for these:

• To understand the full UI layout of a screen
• To find all clickable or interactive elements
• To build custom element logic
• To debug which elements TestDriver can find
• To do an accessibility audit

<Note> **Availability**: `parse()` needs an enterprise plan or a self-hosted plan. It uses OmniParser v2 on the server for element detection. </Note>

Syntax

const result = await testdriver.parse()

Parameters

None.

Returns

`Promise<ParseResult>` - Object containing detected UI elements

ParseResult

| Property | Type | Description | |----------|------|-------------| | `elements` | `ParsedElement[]` | Array of detected UI elements | | `annotatedImageUrl` | `string` | URL of the annotated screenshot with bounding boxes | | `imageWidth` | `number` | Width of the analyzed screenshot | | `imageHeight` | `number` | Height of the analyzed screenshot |

ParsedElement

| Property | Type | Description | |----------|------|-------------| | `index` | `number` | Element index | | `type` | `string` | Element type (e.g. `"text"`, `"icon"`, `"button"`) | | `content` | `string` | Text content or description of the element | | `interactivity` | `string` | Interactivity level (e.g. `"clickable"`, `"non-interactive"`) | | `bbox` | `object` | Bounding box in pixel coordinates `{x0, y0, x1, y1}` | | `boundingBox` | `object` | Bounding box as `{left, top, width, height}` |

Examples

Get All Elements on Screen

const result = await testdriver.parse();
console.log(`Found ${result.elements.length} elements`);

result.elements.forEach((el, i) => {
  console.log(`${i + 1}. [${el.type}] "${el.content}" (${el.interactivity})`);
});

Find Clickable Elements

const result = await testdriver.parse();

const clickable = result.elements.filter(e => e.interactivity === 'clickable');
console.log(`Found ${clickable.length} clickable elements`);

clickable.forEach(el => {
  console.log(`- "${el.content}" at (${el.bbox.x0}, ${el.bbox.y0})`);
});

Find and Click an Element by Content

const result = await testdriver.parse();

// Find a "Submit" button
const submitBtn = result.elements.find(e => 
  e.content.toLowerCase().includes('submit') && e.interactivity === 'clickable'
);

if (submitBtn) {
  // Calculate center of the bounding box
  const x = Math.round((submitBtn.bbox.x0 + submitBtn.bbox.x1) / 2);
  const y = Math.round((submitBtn.bbox.y0 + submitBtn.bbox.y1) / 2);
  
  await testdriver.click({ x, y });
}

Filter by Element Type

const result = await testdriver.parse();

// Get all text elements
const textElements = result.elements.filter(e => e.type === 'text');
textElements.forEach(e => console.log(`Text: "${e.content}"`));

// Get all icons
const icons = result.elements.filter(e => e.type === 'icon');
console.log(`Found ${icons.length} icons`);

// Get all buttons
const buttons = result.elements.filter(e => e.type === 'button');
console.log(`Found ${buttons.length} buttons`);

Build Custom Assertions

import { describe, expect, it } from "vitest";
import { TestDriver } from "testdriverai/vitest/hooks";

describe("Login Page", () => {
  it("should have expected form elements", async (context) => {
    const testdriver = TestDriver(context);
    
    await testdriver.provision.chrome({
      url: 'https://myapp.com/login',
    });

    const result = await testdriver.parse();
    
    // Assert expected elements exist
    const textContent = result.elements.map(e => e.content.toLowerCase());
    expect(textContent).toContain('email');
    expect(textContent).toContain('password');
    
    // Assert there are clickable elements
    const clickable = result.elements.filter(e => e.interactivity === 'clickable');
    expect(clickable.length).toBeGreaterThan(0);
  });
});

Use Bounding Box Coordinates

const result = await testdriver.parse();

result.elements.forEach(el => {
  // Pixel coordinates
  console.log(`Element "${el.content}":`);
  console.log(`  bbox: (${el.bbox.x0}, ${el.bbox.y0}) to (${el.bbox.x1}, ${el.bbox.y1})`);
  console.log(`  size: ${el.boundingBox.width}x${el.boundingBox.height}`);
  console.log(`  position: left=${el.boundingBox.left}, top=${el.boundingBox.top}`);
});

View Annotated Screenshot

const result = await testdriver.parse();

// The annotated image shows all detected elements with bounding boxes
console.log('Annotated screenshot:', result.annotatedImageUrl);
console.log(`Image dimensions: ${result.imageWidth}x${result.imageHeight}`);

How It Works

1. TestDriver captures a screenshot of the current screen 2. The image is sent to the TestDriver API 3. OmniParser v2 analyzes the image to detect all UI elements 4. Each element is classified by type (text, icon, button, etc.) and interactivity 5. Bounding box coordinates are returned in pixel coordinates matching the screen resolution

<Note> OmniParser detects elements visually — it works with any UI framework, native apps, and even non-standard interfaces. It does not rely on DOM or accessibility trees. </Note>

Best Practices

<AccordionGroup> <Accordion title="Use find() for targeting specific elements"> For locating and interacting with a specific element, prefer `find()` which uses AI vision. Use `parse()` when you need a complete inventory of all elements on screen.

    // Prefer this for clicking a specific element
    await testdriver.find("Submit button").cl
