Provision methods are the starting point for most tests. They launch applications in your sandbox and prepare the environment for testing.

Chrome Browser

The most common starting point for web testing. Launches Chrome browser and navigates to a URL.

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

|--------|------|---------|-------------|

Example: Basic Web Test

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

describe("Login Flow", () => {
  it("should log in successfully", async (context) => {
    const testdriver = TestDriver(context);
    
    await testdriver.provision.chrome({
      url: 'https://myapp.com/login',
    });

    await testdriver.find("Email input").click();
    await testdriver.type("[email protected]");
    
    await testdriver.find("Password input").click();
    await testdriver.type("password123");
    
    await testdriver.find("Sign In button").click();
    
    const result = await testdriver.assert("the dashboard is visible");
    expect(result).toBeTruthy();
  });
});

<Info>

provision.chrome() automatically starts Dashcam recording and waits for Chrome to be ready before returning.

</Info>

Chrome Extensions

Launch Chrome with a custom extension loaded. Supports both local extensions and Chrome Web Store extensions.

Load from Local Path

Clone or create an extension locally, then load it:

// First, get the extension onto the sandbox
await testdriver.exec(
  'sh',
  'git clone https://github.com/user/my-extension.git /tmp/my-extension',
  60000
);

// Launch Chrome with the extension
await testdriver.provision.chromeExtension({
  extensionPath: '/tmp/my-extension',
  url: 'https://example.com'
});

Load from Chrome Web Store

Load any published extension by its Chrome Web Store ID:

await testdriver.provision.chromeExtension({
  extensionId: 'cjpalhdlnbpafiamejdnhcphjbkeiagm', // uBlock Origin
  url: 'https://example.com'
});

<Tip>

Find the extension ID in the Chrome Web Store URL. For example, https://chrome.google.com/webstore/detail/ublock-origin/cjpalhdlnbpafiamejdnhcphjbkeiagm → ID is cjpalhdlnbpafiamejdnhcphjbkeiagm

</Tip>

Options

|--------|------|---------|-------------|

| url | string | - | URL to navigate to after launch |

You must provide either extensionPath or extensionId, but not both.

</Warning>

Example: Testing a Chrome Extension

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

describe("Chrome Extension Test", () => {
  it("should load and interact with extension", async (context) => {
    const testdriver = TestDriver(context);

    // Clone extension from GitHub
    await testdriver.exec(
      'sh',
      'git clone https://github.com/user/my-extension.git /tmp/my-extension',
      60000,
      true
    );

    // Launch Chrome with extension loaded
    await testdriver.provision.chromeExtension({
      extensionPath: '/tmp/my-extension',
      url: 'https://testdriver.ai'
    });

    // Click extensions puzzle icon
    const extensionsButton = await testdriver.find("puzzle-shaped icon in Chrome toolbar");
    await extensionsButton.click();

    // Interact with your extension
    const myExtension = await testdriver.find("My Extension in the dropdown");
    await myExtension.click();

    const result = await testdriver.assert("extension popup is visible");
    expect(result).toBeTruthy();
  });
});

Desktop Apps

Download and install desktop applications. Supports .deb, .rpm, .msi, .exe, .AppImage, .dmg, .pkg, and shell scripts.

const filePath = await testdriver.provision.installer({
  url: 'https://example.com/app.deb',
  appName: 'MyApp',  // Focus this app after install
  launch: true,      // Auto-launch after install
});

Options

|--------|------|---------|-------------|

Supported File Types

| Extension | OS | Install Method |

|-----------|-----|----------------|

| .deb | Linux | dpkg -i + apt-get install -f |

| .rpm | Linux | rpm -i |

| .AppImage | Linux | chmod +x |

| .sh | Linux | chmod +x + execute |

| .msi | Windows | msiexec /i /quiet |

| .exe | Windows | Silent install (/S) |

| .dmg | macOS | Mount + copy to Applications |

| .pkg | macOS | installer -pkg |

Example: Install and Test a Desktop App

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

describe("Desktop App Test", () => {
  it("should install and launch app", async (context) => {
    const testdriver = TestDriver(context);

    // Download and install
    const installerPath = await testdriver.provision.installer({
      url: 'https://github.com/sharkdp/bat/releases/download/v0.24.0/bat_0.24.0_amd64.deb',
    });

    // Verify installation
    const output = await testdriver.exec('sh', 'bat --version', 5000);
    expect(output).toContain('bat');
  });
});

Example: Windows Installer

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

describe("Windows App Test", () => {
  it("should install on Windows", async (context) => {
    const testdriver = TestDriver(context, { 
      os: 'windows'
    });

    // Download MSI installer
    const installerPath = await testdriver.provision.installer({
      url: 'https://example.com/app.msi',
      launch: false,  // Don't auto-launch
    });

    // Custom installation if needed
    await testdriver.exec(
      'pwsh',
      `Start-Process msiexec.exe -ArgumentList "/i", "${installerPath}", "/qn" -Wait`,
      120000
    );

    // Verify installation
    const result = await testdriver.assert("application is installed");
    expect(result).toBeTruthy();
  });
});

Manual Installation

Set launch: false to download without auto-installing:

const filePath = await testdriver.provision.installer({
  url: 'https://example.com/custom-script.sh',
  launch: false,
});

// Run custom install commands
await testdriver.exec('sh', `chmod +x "${filePath}"`, 5000);
await testdriver.exec('sh', `"${filePath}" --custom-flag`, 60000);

VS Code

Launch Visual Studio Code with optional workspace and extensions.

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

Options

|--------|------|---------|-------------|

Example: VS Code Extension Test

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

describe("VS Code Test", () => {
  it("should open workspace with extensions", async (context) => {
    const testdriver = TestDriver(context);

    // Create a test project
    await testdriver.exec('sh', 'mkdir -p /tmp/test-project && echo "print(1)" > /tmp/test-project/test.py', 10000);

    // Launch VS Code
    await testdriver.provision.vscode({
      workspace: '/tmp/test-project',
      extensions: ['ms-python.python'],
    });

    // Verify VS Code is ready
    const result = await testdriver.assert("VS Code is open with the project");
    expect(result).toBeTruthy();

    // Open the Python file
    await testdriver.find("test.py in the explorer").click();
  });
});

Choosing the Right Provision Method

| Use Case | Method |

|----------|--------|

| Testing a website | provision.chrome |

| Testing a Chrome extension | provision.chromeExtension |

| Testing a desktop app (needs installation) | provision.installer |

| Testing VS Code or VS Code extensions | provision.vscode |

<Tip>

All provision methods automatically start Dashcam recording and wait for the application to be ready before returning. You don't need to call dashcam.start() manually.

</Tip>

How to use it

Copy the folder

Take testdriverai/testdriver:device-config from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference apt. Without those the skill loads but fails at the first command.
