How to Test OpenHands with Playwright

Test your OpenHands AI development workflows with Playwright’s end-to-end testing framework. You’ll catch UI bugs and ensure agent interactions work correctly by testing in a real browser environment. Use Playwright to automate chat interactions and validate code generation features. View OpenHands’ Playwright configuration from the official repository.

​
Setup

Install Playwright and configure for OpenHands testing: 
npm install playwright

​
Write Tests

Create tests for AI agent functionality: 
import { test, expect } from '@playwright/test';

test('chat interface loads and responds', async ({ page }) => {
  await page.goto('http://localhost:3000');
  
  // Verify chat interface is ready
  await expect(page.locator('[data-testid="chat-input"]')).toBeVisible();
  await expect(page.locator('[data-testid="send-button"]')).toBeEnabled();
  
  // Send a message to the agent
  await page.fill('[data-testid="chat-input"]', 'Create a simple Python function');
  await page.click('[data-testid="send-button"]');
  
  // Verify agent response appears
  await expect(page.locator('.agent-response')).toBeVisible();
  await expect(page.locator('.code-block')).toContainText('def');
});

test('file explorer functionality works', async ({ page }) => {
  await page.goto('http://localhost:3000');
  
  // Test file tree navigation
  await page.click('[data-testid="file-explorer"]');
  await expect(page.locator('.file-tree')).toBeVisible();
  
  // Create new file through UI
  await page.click('[data-testid="new-file-button"]');
  await page.fill('[data-testid="file-name-input"]', 'test.py');
  await page.click('[data-testid="confirm-button"]');
  
  // Verify file appears in explorer
  await expect(page.locator('text=test.py')).toBeVisible();
});
Playwright handles agent response timing, code syntax highlighting, and file system interactions automatically. You can test multi-step workflows, error handling, and agent memory persistence.
