testdriver:client

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

Overview

The TestDriver client is the main entry point for the SDK. It does the authentication and the sandbox connection. It gives access to all test methods.

Constructor

const testdriver = new TestDriver(apiKey, options)

Parameters

<ParamField path="apiKey" type="string" required> Your TestDriver API key from the [dashboard](https://console.testdriver.ai/settings) </ParamField> <ParamField path="options" type="object"> The configuration options for the client. See [SDK Options](/options) for the full list, with defaults and examples for each option. </ParamField>

Example

import TestDriver from 'testdriverai';

// API key is automatically loaded from TD_API_KEY in .env
const testdriver = new TestDriver({
  os: 'windows',
  resolution: '1920x1080',
  logging: true,
  analytics: true
});

// With AI config for stricter verification
const testdriver = new TestDriver({
  ai: { temperature: 0, top: { p: 0.9, k: 40 } }
});

// Or pass API key explicitly
const testdriver = new TestDriver('your-api-key', {
  os: 'windows'
});

Authentication

auth()

Authenticate with the TestDriver API.

await testdriver.auth()

Returns: Promise<string> - Authentication token

Example:

await testdriver.auth();

<Note> You must call `auth()` before `connect()`. Most examples call both sequentially. </Note>

Connection Management

connect()

Connect to a sandbox environment. This creates or reconnects to a virtual machine where your tests will run.

await testdriver.connect(options)

Parameters

<ParamField path="options" type="object"> Connection options <Expandable title="properties"> <ParamField path="newSandbox" type="boolean" default="false"> Force creation of a new sandbox instead of reusing an existing one </ParamField>

<ParamField path="sandboxId" type="string">
  Existing sandbox ID to reconnect to
</ParamField>

<ParamField path="ip" type="string">
  Direct IP address to connect to (for self-hosted sandboxes)
</ParamField>

<ParamField path="sandboxAmi" type="string">
  AMI to use for the sandbox (AWS deployments)
</ParamField>

<ParamField path="sandboxInstance" type="string">
  Instance type for the sandbox (AWS deployments)
</ParamField>

<ParamField path="preview" type="string" default="browser">
  Preview mode for live test visualization:
  - `"browser"` - Opens debugger in default browser (default)
  - `"ide"` - Opens preview in IDE panel (VSCode, Cursor - requires TestDriver extension)
  - `"none"` - Headless mode, no visual preview
</ParamField>

<ParamField path="headless" type="boolean" default="false">
  **Deprecated**: Use `preview: "none"` instead. Run in headless mode without opening the debugger.
</ParamField>

<ParamField path="keepAlive" type="number" default="60000">
  Keep sandbox alive for the specified number of milliseconds after disconnect. Set to `0` to terminate immediately on disconnect. Useful for debugging or reconnecting to the same sandbox.
</ParamField>

</Expandable> </ParamField>

Returns: Promise<Object> - Sandbox instance details including instanceId, ip, vncPort, etc.

Examples

Basic connection:

await testdriver.connect();

Reconnect to existing sandbox:

const instance = await testdriver.connect({ 
  sandboxId: 'existing-sandbox-id-123' 
});

Self-hosted sandbox:

await testdriver.connect({ 
  ip: '192.168.1.100'
});

disconnect()

Disconnect from the sandbox and clean up resources.

await testdriver.disconnect()

Returns: Promise<void>

Example:

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

Instance Information

getInstance()

Get the current sandbox instance details.

const instance = testdriver.getInstance()

Returns: Object | null - Sandbox instance information

Example:

const instance = testdriver.getInstance();
console.log('Instance ID:', instance.instanceId);
console.log('IP Address:', instance.ip);

getSessionId()

Get the current session ID for tracking and debugging.

const sessionId = testdriver.getSessionId()

Returns: string | null - Session ID

Example:

const sessionId = testdriver.getSessionId();
console.log('Session:', sessionId);

Logging & Events

setLogging()

Enable or disable console logging at runtime.

testdriver.setLogging(enabled)

Parameters:

• enabled (boolean) - Whether to enable logging

Example:

// Disable logging for cleanup operations
testdriver.setLogging(false);
await testdriver.disconnect();
testdriver.setLogging(true);

getEmitter()

Get the event emitter for custom event handling.

const emitter = testdriver.getEmitter()

Returns: EventEmitter2 - Event emitter instance

Example:

const emitter = testdriver.getEmitter();

emitter.on('command:start', (data) => {
  console.log('Command started:', data);
});

emitter.on('command:success', (data) => {
  console.log('Command succeeded:', data);
});

emitter.on('command:error', (error) => {
  console.error('Command failed:', error);
});

Complete Example

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

describe('My Test Suite', () => {
  let testdriver;

  beforeAll(async () => {
    // Initialize client - API key loaded automatically from .env
    testdriver = new TestDriver({
      os: 'windows',
      resolution: '1366x768',
      logging: true
    });
    
    // Set up event listeners
    const emitter = testdriver.getEmitter();
    emitter.on('log:info', (msg) => console.log('[INFO]', msg));
    
    // Authenticate and connect
    await testdriver.auth();
    const instance = await testdriver.connect();
    
    console.log('Connected to sandbox:', instance.instanceId);
  });

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

  it('runs a test', async () => {
    // Your test code here
  });
});

Best Practices

<AccordionGroup> <Accordion title="Reuse sandboxes across tests"> Use `beforeAll`/`afterAll` to create one sandbox per test suite rather than per test. This significantly reduces execution time. </Accordion> <Accordion title="Handle connection errors gracefully"> Wrap `connect()` in a try-catch block to handle network issues or quota limits:

```javascript
try {
  await testdriver.connect();
} catch (error) {
  console.error('Failed to connect:', error.message);
  throw error;
}
```

</Accordion> <Accordion title="Always disconnect"> Use `afterAll` or try-finally blocks to ensure `disconnect()` is called even if tests fail. This prevents orphaned sandboxes. </Accordion> <Accordion title="Use environment variables for API keys"> Never hardcode API keys. The SDK automatically loads `TD_API_KEY` from your `.env` file:

```bash .env
TD_API_KEY=your_api_key_here
```

```javascript
// API key is loaded automatically - no need to pass it!
const testdriver = new TestDriver();
```

</Accordion> </AccordionGroup>
