Overview

The Provision API sets up applications in your sandbox before tests run. It handles downloading, installing, and launching browsers, desktop apps, VS Code, Chrome extensions, and more.

Access provision methods via testdriver.provision.*:

javascript

await testdriver.provision.chrome({ url: 'https://example.com' });

<Note> When `reconnect: true` is set on the client, **all provision methods are skipped** since the application is assumed to already be running. </Note>

Methods

chrome()

Launch Google Chrome with an optional URL.

javascript

await testdriver.provision.chrome(options?)

<ParamField path="options" type="ProvisionChromeOptions"> <Expandable title="properties"> <ParamField path="url" type="string" default="http://testdriver-sandbox.vercel.app/"> URL to navigate to after launch. </ParamField>

code

<ParamField path="maximized" type="boolean" default={true}>
  Launch Chrome in maximized window mode.
</ParamField>

<ParamField path="guest" type="boolean" default={false}>
  Launch Chrome in guest profile mode.
</ParamField>

</Expandable> </ParamField>

javascript

// Basic
await testdriver.provision.chrome({ url: 'https://example.com' });

// With guest mode
await testdriver.provision.chrome({
  url: 'https://example.com',
  guest: true,
  maximized: true,
});

chromeExtension()

Install and launch a Chrome extension. You can install from a local unpacked directory or from the Chrome Web Store by extension ID.

javascript

await testdriver.provision.chromeExtension(options)

<ParamField path="options" type="ProvisionChromeExtensionOptions" required> One of `extensionPath` or `extensionId` is required. <Expandable title="properties"> <ParamField path="extensionPath" type="string"> Local path to an unpacked extension directory. The extension files are uploaded to the sandbox. </ParamField>

code

<ParamField path="extensionId" type="string">
  Chrome Web Store extension ID to install.
</ParamField>

<ParamField path="maximized" type="boolean" default={true}>
  Launch Chrome in maximized window mode.
</ParamField>

</Expandable> </ParamField>

javascript

// From local directory
await testdriver.provision.chromeExtension({
  extensionPath: './my-extension',
});

// From Chrome Web Store
await testdriver.provision.chromeExtension({
  extensionId: 'abcdefghijklmnop',
});

vscode()

Launch Visual Studio Code with an optional workspace and extensions.

javascript

await testdriver.provision.vscode(options?)

<ParamField path="options" type="ProvisionVSCodeOptions"> <Expandable title="properties"> <ParamField path="workspace" type="string"> Path to a workspace folder or `.code-workspace` file to open. </ParamField>

code

<ParamField path="extensions" type="string[]" default={[]}>
  Array of VS Code extension IDs to install before launching.
</ParamField>

</Expandable> </ParamField>

javascript

await testdriver.provision.vscode({
  workspace: '/home/testdriver/project',
  extensions: ['ms-python.python', 'esbenp.prettier-vscode'],
});

installer()

Download and run an application installer. Supports .msi, .exe, .deb, .rpm, .appimage, .sh, .dmg, and .pkg formats.

javascript

await testdriver.provision.installer(options)

<ParamField path="options" type="ProvisionInstallerOptions" required> <Expandable title="properties"> <ParamField path="url" type="string" required> Download URL for the installer. </ParamField>

code

<ParamField path="filename" type="string">
  Override the auto-detected filename from the URL.
</ParamField>

<ParamField path="appName" type="string">
  Application name to focus after installation completes.
</ParamField>

<ParamField path="launch" type="boolean" default={true}>
  Whether to focus/launch the app after installation.
</ParamField>

</Expandable> </ParamField>

Behavior:

•Downloads the installer from the URL
•Auto-detects the install method based on file extension
•Runs the appropriate install command (e.g., msiexec for .msi, dpkg for .deb)
•Optionally focuses the installed application

javascript

// Windows MSI installer
await testdriver.provision.installer({
  url: 'https://example.com/app-setup.msi',
  appName: 'MyApp',
});

// Linux DEB package
await testdriver.provision.installer({
  url: 'https://example.com/app.deb',
  appName: 'MyApp',
  launch: true,
});

electron()

Launch an Electron application.

javascript

await testdriver.provision.electron(options)

<ParamField path="options" type="ProvisionElectronOptions" required> <Expandable title="properties"> <ParamField path="appPath" type="string" required> Path to the Electron application directory or executable. </ParamField>

code

<ParamField path="args" type="string[]" default={[]}>
  Additional command-line arguments to pass to the Electron app.
</ParamField>

</Expandable> </ParamField>

javascript

await testdriver.provision.electron({
  appPath: '/home/testdriver/my-electron-app',
  args: ['--no-sandbox'],
});

dashcam()

Start Dashcam recording with custom options. Usually called automatically by other provision methods, but can be called directly for custom configurations.

javascript

await testdriver.provision.dashcam(options?)

<ParamField path="options" type="ProvisionDashcamOptions"> <Expandable title="properties"> <ParamField path="logPath" type="string"> Path to the TestDriver log file. Defaults to `/tmp/testdriver.log` (Linux) or `C:\Users\testdriver\testdriver.log` (Windows). </ParamField>

code

<ParamField path="logName" type="string" default="TestDriver Log">
  Display name for the log file in the Dashcam replay.
</ParamField>

<ParamField path="webLogs" type="boolean" default={true}>
  Enable web traffic log capture.
</ParamField>

<ParamField path="title" type="string">
  Recording title for the Dashcam session.
</ParamField>

</Expandable> </ParamField>

javascript

await testdriver.provision.dashcam({
  title: 'Login Flow Test',
  logPath: '/tmp/my-app.log',
  logName: 'Application Log',
  webLogs: true,
});

Reconnect Behavior

When reconnect: true is set on the client, all provision methods are wrapped in a Proxy that intercepts calls and skips them silently. This is because when reconnecting to an existing sandbox, the applications are already running.

javascript

const testdriver = new TestDriver({
  reconnect: true,
});

await testdriver.ready();

// These calls are silently skipped:
await testdriver.provision.chrome({ url: 'https://example.com' });
await testdriver.provision.dashcam();
