find()

Overview

Locate UI elements on screen using AI-powered natural language descriptions. Returns an Element object that can be interacted with.

Syntax

const element = await testdriver.find(description)

Parameters

description

string

required

Natural language description of the element to find

Returns

Promise<Element> - Element instance that has been automatically located

Examples

Basic Element Finding

// Find by role
const button = await testdriver.find('submit button');
const input = await testdriver.find('email input field');

// Find by text content
const link = await testdriver.find('Contact Us link');
const heading = await testdriver.find('Welcome heading');

// Find by visual appearance
const icon = await testdriver.find('red warning icon');
const image = await testdriver.find('company logo image');

Finding with Context

// Provide location context
const field = await testdriver.find('username input in the login form');
const button = await testdriver.find('delete button in the top right corner');

// Describe nearby elements
const input = await testdriver.find('input field below the email label');
const checkbox = await testdriver.find('checkbox next to "Remember me"');

// Describe visual position
const menu = await testdriver.find('hamburger menu icon in the top left');

Interacting with Found Elements

// Find and click
const submitBtn = await testdriver.find('submit button');
await submitBtn.click();

// Find and verify
const message = await testdriver.find('success message');
if (message.found()) {
  console.log('Success message appeared');
}

// Find and extract info
const price = await testdriver.find('product price');
console.log('Price location:', price.coordinates);
console.log('Price text:', price.text);

Element Object

The returned Element object provides:

Methods

found() - Check if element was located
click(action) - Click the element
hover() - Hover over the element
doubleClick() - Double-click the element

See Elements Reference for complete details.

Best Practices

Be specific in descriptionsMore specific descriptions improve accuracy:

// ✅ Good
await testdriver.find('blue submit button below the email field');

// ❌ Too vague
await testdriver.find('button');

Always check if foundVerify elements were located before interacting:

const element = await testdriver.find('login button');
if (!element.found()) {
  throw new Error('Login button not found');
}
await element.click();

Include visual or positional context

// Include color
await testdriver.find('red error icon');

// Include position
await testdriver.find('search button in the top navigation bar');

// Include nearby text
await testdriver.find('checkbox next to "I agree to terms"');

Polling for Dynamic Elements

For elements that may not be immediately visible:

// Poll until element appears
let loginButton;
const maxAttempts = 30;

for (let i = 0; i < maxAttempts; i++) {
  loginButton = await testdriver.find('login button');
  if (loginButton.found()) break;
  await new Promise(r => setTimeout(r, 1000));
}

if (!loginButton.found()) {
  throw new Error('Login button never appeared');
}

await loginButton.click();

Helper Function

async function waitForElement(testdriver, description, timeout = 30000) {
  const startTime = Date.now();
  
  while (Date.now() - startTime < timeout) {
    const element = await testdriver.find(description);
    if (element.found()) return element;
    await new Promise(r => setTimeout(r, 1000));
  }
  
  throw new Error(`Element "${description}" not found after ${timeout}ms`);
}

// Usage
const button = await waitForElement(testdriver, 'submit button', 10000);
await button.click();

Use Cases

Form Fields

const emailField = await testdriver.find('email input field');
await emailField.click();
await testdriver.type('[email protected]');

const passwordField = await testdriver.find('password input');
await passwordField.click();
await testdriver.type('MyP@ssw0rd');

Buttons and Links

const submitBtn = await testdriver.find('submit button');
await submitBtn.click();

const cancelLink = await testdriver.find('cancel link');
await cancelLink.click();

const menuIcon = await testdriver.find('hamburger menu icon');
await menuIcon.click();

Dynamic Content

// Wait for loading to complete
let content;
for (let i = 0; i < 30; i++) {
  content = await testdriver.find('results table');
  if (content.found()) break;
  await new Promise(r => setTimeout(r, 1000));
}

// Interact with loaded content
const firstRow = await testdriver.find('first row in the results table');
await firstRow.click();

Complex UI Elements

// Modals and dialogs
const modal = await testdriver.find('confirmation dialog');
if (modal.found()) {
  const confirmBtn = await testdriver.find('confirm button in the dialog');
  await confirmBtn.click();
}

// Dropdown menus
const dropdown = await testdriver.find('country dropdown');
await dropdown.click();

const option = await testdriver.find('United States option');
await option.click();

Complete Example

import { beforeAll, afterAll, describe, it, expect } from 'vitest';
import TestDriver from 'testdriverai';

describe('Element Finding', () => {
  let testdriver;

  beforeAll(async () => {
    client = new TestDriver(process.env.TD_API_KEY);
    await testdriver.auth();
    await testdriver.connect({ newSandbox: true });
  });

  afterAll(async () => {
    await testdriver.disconnect();
  });

  it('should find and interact with elements', async () => {
    await testdriver.focusApplication('Google Chrome');
    
    // Find login form elements
    const usernameField = await testdriver.find('username input field');
    expect(usernameField.found()).toBe(true);
    
    await usernameField.click();
    await testdriver.type('testuser');
    
    // Find with context
    const passwordField = await testdriver.find('password input below username');
    await passwordField.click();
    await testdriver.type('password123');
    
    // Find button
    const submitBtn = await testdriver.find('green submit button');
    expect(submitBtn.found()).toBe(true);
    
    console.log('Button location:', submitBtn.centerX, submitBtn.centerY);
    
    await submitBtn.click();
    
    // Wait for success message
    let successMsg;
    for (let i = 0; i < 10; i++) {
      successMsg = await testdriver.find('success notification');
      if (successMsg.found()) break;
      await new Promise(r => setTimeout(r, 1000));
    }
    
    expect(successMsg.found()).toBe(true);
  });
});

click() - Click on found elements
hover() - Hover over elements
assert() - Verify element states

findAll()

Locate all elements matching a description, rather than just one.

Syntax

const elements = await testdriver.findAll(description, options)

Parameters

description

string

required

Natural language description of elements to find

options

object | number

Optional cache options (same as find())

Show properties

cacheKey

string

Cache key for storing element location

cacheThreshold

number

Similarity threshold (0-1) for cache matching. Set to -1 to disable cache.

Returns

Promise<Element[]> - Array of Element instances

Examples

Basic Usage

// Find all matching elements
const buttons = await testdriver.findAll('button');
console.log(`Found ${buttons.length} buttons`);

// Interact with specific element
if (buttons.length > 0) {
  await buttons[0].click(); // Click first button
}

// Iterate over all
for (const button of buttons) {
  console.log(`Button at (${button.x}, ${button.y})`);
}

Finding Multiple Items

// Find all list items
const items = await testdriver.findAll('list item');

// Find specific item by index
const thirdItem = items[2];
await thirdItem.click();

// Check all items
for (let i = 0; i < items.length; i++) {
  console.log(`Item ${i + 1}: ${items[i].text || 'No text'}`);
}

With Caching

// Cache element locations for faster subsequent runs
const menuItems = await testdriver.findAll('menu item', {
  cacheKey: 'main-menu-items'
});

// First run: ~2-3 seconds (AI call)
// Subsequent runs: ~100ms (cache hit)

Empty Results

// Returns empty array if nothing found (doesn't throw error)
const errors = await testdriver.findAll('error message');

if (errors.length === 0) {
  console.log('No errors found - test passed!');
} else {
  console.log(`Found ${errors.length} errors`);
}

Differences from find()

Feature	find()	findAll()
Return type	Single `Element`	Array of `Element[]`
If nothing found	Throws `ElementNotFoundError`	Returns empty array `[]`
Chainable	✅ Yes: `await find('button').click()`	❌ No (returns array)
Use case	One specific element	Multiple similar elements
Cache support	✅ Yes	✅ Yes

Use Cases

Table Rows

// Find all rows in a table
const rows = await testdriver.findAll('table row');

// Click every row
for (const row of rows) {
  await row.click();
  await new Promise(r => setTimeout(r, 500)); // Wait between clicks
}

// Or click specific row
await rows[2].click(); // Click third row

Checkboxes/Radio Buttons

// Find all checkboxes
const checkboxes = await testdriver.findAll('checkbox');

// Check all boxes
for (const checkbox of checkboxes) {
  await checkbox.click();
}

// Or select first unchecked
const unchecked = checkboxes[0];
await unchecked.click();

Navigation Links

// Find all navigation links
const navLinks = await testdriver.findAll('navigation link');

// Validate all are present
expect(navLinks.length).toBeGreaterThan(0);

// Click specific link by text
const homeLink = navLinks.find(link => 
  link.text?.toLowerCase().includes('home')
);

if (homeLink) {
  await homeLink.click();
}

Conditional Interactions

// Check if any error messages exist
const errors = await testdriver.findAll('error message');

if (errors.length > 0) {
  console.log(`Found ${errors.length} validation errors`);
  
  // Log each error location
  errors.forEach((error, i) => {
    console.log(`Error ${i + 1} at (${error.x}, ${error.y})`);
  });
} else {
  console.log('Form validation passed!');
}

Complete Example

import { test, expect } from 'vitest';
import { chrome } from 'testdriverai/presets';

test('select multiple items from list', async (context) => {
  const { testdriver } = await chrome(context, {
    url: 'https://example.com/products'
  });
  
  // Find all product cards
  const products = await testdriver.findAll('product card');
  
  expect(products.length).toBeGreaterThan(0);
  console.log(`Found ${products.length} products`);
  
  // Click first 3 products
  const productsToSelect = Math.min(3, products.length);
  
  for (let i = 0; i < productsToSelect; i++) {
    await products[i].click();
    console.log(`Selected product ${i + 1}`);
    await new Promise(r => setTimeout(r, 500)); // Brief pause
  }
  
  // Verify selections
  const selectedBadges = await testdriver.findAll('selected badge');
  expect(selectedBadges.length).toBe(productsToSelect);
});

Best Practices

Handle empty arrays gracefully

// ✅ Good - check length first
const items = await testdriver.findAll('list item');
if (items.length > 0) {
  await items[0].click();
}

// ❌ Bad - may throw error
const items = await testdriver.findAll('list item');
await items[0].click(); // Error if array is empty!

Use find() for single elements

// ✅ Use find() when you need exactly one
const submitBtn = await testdriver.find('submit button');
await submitBtn.click();

// ❌ Unnecessary - findAll() returns array
const buttons = await testdriver.findAll('submit button');
await buttons[0].click(); // Extra array handling

Cache for performance

// First run - slow (AI call)
const items = await testdriver.findAll('menu item', {
  cacheKey: 'menu-items'
});

// Subsequent runs - fast (cache hit)
// ~10-20x faster than without cache
