How It Works

TestDriver manages the AWS EC2 instances for your tests automatically:

1. Deploy CloudFormation. Set up the infrastructure one time.
2. Configure Vitest. Add one line to your config.
3. Run Tests. The instances start automatically, run the tests, and stop.

That is all. You do not need to manage the instances by hand.

Overview

The setup process is simple:

1. Deploy CloudFormation — Creates VPC, security groups, IAM roles, and launch templates
2. Configure Vitest — Add setup-aws to automatically manage instance lifecycle
3. Run Tests — Set TD_OS=windows with AWS credentials and instances spawn/terminate automatically

Prerequisites

Before you begin, ensure you have:

• AWS account with CloudFormation permissions
• AWS CLI installed and configured (aws configure)
• Access to the TestDriver AMI — Contact us with your AWS region
• A GitHub repository for your tests

<Tip> The TestDriver Golden Image AMI ID is `ami-0504bf50fad62f312`. Contact us to get access in your preferred AWS region. </Tip>

Step 1: Deploy CloudFormation Stack

Our CloudFormation template creates all the AWS infrastructure you need:

• Dedicated VPC with public subnet
• Security group with required port access
• IAM roles and instance profiles
• EC2 launch template for instance creation

<Tabs> <Tab title="GUI"> Click the button below to launch the CloudFormation stack in your AWS Console:

  horizontal 
  arrow
>
  Deploy TestDriver infrastructure with one click
</Card>

Configure the stack parameters:
- **Stack name**: `testdriver-infrastructure` (or your preferred name)
- **ProjectTag**: `testdriver`
- **AllowedIngressCidr**: Your IP range (e.g., `203.0.113.0/24`)
- **InstanceType**: `c5.xlarge` (recommended)
- **CreateKeyPair**: `true`

<Warning>
  **Security**: Replace `AllowedIngressCidr` with your specific IP ranges to restrict VPC access. Avoid using `0.0.0.0/0` in production.
</Warning>

### Get Your Launch Template ID

After the stack creation completes, navigate to the **Outputs** tab to find your `LaunchTemplateId`:

![Launch Template ID](/images/content/self-hosted/launchtemplateid.png)

<Tip>
  **Save this ID** — you'll need it for spawning instances and CI configuration.
</Tip>

</Tab> <Tab title="CLI"> Download the template from the [TestDriver CLI repository](https://github.com/testdriverai/testdriverai/blob/main/setup/aws/cloudformation.yaml), then deploy:

```bash
aws cloudformation deploy \
  --template-file setup/aws/cloudformation.yaml \
  --stack-name testdriver-infrastructure \
  --parameter-overrides \
    ProjectTag=testdriver \
    AllowedIngressCidr=0.0.0.0/0 \
    InstanceType=c5.xlarge \
    CreateKeyPair=true \
  --capabilities CAPABILITY_IAM
```

<Warning>
  **Security**: Replace `AllowedIngressCidr=0.0.0.0/0` with your specific IP ranges to restrict VPC access.
</Warning>

### Get Your Launch Template ID

After deployment completes, retrieve the launch template ID:

```bash
aws cloudformation describe-stacks \
  --stack-name testdriver-infrastructure \
  --query 'Stacks[0].Outputs[?OutputKey==`LaunchTemplateId`].OutputValue' \
  --output text
```

<Tip>
  **Save this ID** — you'll need it for spawning instances and CI configuration.
</Tip>

</Tab> </Tabs>

Step 2: Configure Vitest

Add the AWS setup hook to your vitest.config.mjs:

import { defineConfig } from 'vitest/config';
import { config } from 'dotenv';
import TestDriver from 'testdriverai/vitest';

config(); // Load .env file

export default defineConfig({
  test: {
    testTimeout: 900000,
    hookTimeout: 900000,
    maxConcurrency: 3,
    reporters: [
      'default',
      TestDriver(),
      ['junit', { outputFile: 'test-report.junit.xml' }]
    ],
    setupFiles: ['testdriverai/vitest/setup', 'testdriverai/vitest/setup-aws'],
  },
});

<Note> **That's it!** The `setup-aws` hook automatically spawns and terminates instances when `TD_OS=windows` is set. No manual instance management needed. </Note>

Step 3: Write Your Tests

Tests should use context.ip || process.env.TD_IP for the IP configuration:

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

describe("My Test", () => {
  it("should run on self-hosted instance", async (context) => {
    const testdriver = TestDriver(context, {
      ip: context.ip || process.env.TD_IP,
    });

    await testdriver.provision.chrome({ url: "https://example.com" });
    // ... your test steps
  });
});

<Note> **How it works**: When `TD_OS=windows` with AWS credentials, `context.ip` is automatically set by the setup hook. When running without AWS setup (cloud-hosted), both are undefined and TestDriver uses the cloud. When `TD_IP` is provided manually, it takes precedence. </Note>

Step 4: Run Tests

Locally

TD_OS=windows \
AWS_REGION=us-east-2 \
AWS_LAUNCH_TEMPLATE_ID=lt-xxx \
AMI_ID=ami-0504bf50fad62f312 \
vitest run

<Note> Each test gets its own fresh EC2 instance that's automatically terminated after completion. </Note>

In GitHub Actions

Automate testing with self-hosted instances in your CI/CD pipeline. TestDriver automatically spawns a fresh instance for each test, runs the test, and terminates the instance.

        with:
          name: test-results
          path: test-report.junit.xml

<Note> **Automatic Instance Management**: Setting `TD_OS=windows` with AWS credentials enables automatic instance spawning. Each test gets its own fresh instance that's terminated after the test completes. </Note>

Example Workflows

For complete production examples, see:

• Scheduled Tests — Daily automated test runs
• Reusable Workflow — Shared configuration for PR and scheduled tests

Advanced Usage

Using an Existing Instance

If you already have a running instance, you can skip automatic spawning by providing TD_IP:

TD_OS=windows TD_IP=1.2.3.4 vitest run

The setup-aws hook will detect TD_IP is already set and skip spawning a new instance.

Manual Instance Management

For advanced use cases, you can manually spawn instances using the spawn-runner.sh script:

AWS_REGION=us-east-2 \
AMI_ID=ami-0504bf50fad62f312 \
AWS_LAUNCH_TEMPLATE_ID=lt-xxx \
bash setup/aws/spawn-runner.sh

Output:

PUBLIC_IP=1.2.3.4
INSTANCE_ID=i-1234567890abcdef0
AWS_REGION=us-east-2

Then manually terminate when done:

aws ec2 terminate-instances \
  --instance-ids i-1234567890abcdef0 \
  --region us-east-2

For complete production examples, see:

• Scheduled Tests — Daily automated test runs
• Reusable Workflow — Shared configuration for PR and scheduled tests

Connecting to an Instance

You can connect to running instances via:

• RDP — Use the public IP on port 3389
• VNC — Access via web browser at http://<public-ip>:5900
• AWS Console — Use EC2 Instance Connect or Session Manager

<Note> Stopped instances retain their EBS volumes and can be restarted later. Terminated instances are permanently deleted. Always terminate instances when done to avoid storage costs. </Note>

AMI Customization

The TestDriver Golden Image comes pre-configured with:

• Windows Server with desktop environment
• VNC + web server for remote access
• Python, Node.js, Git
• TestDriver agent and dependencies

Creating a Custom AMI

You can customize the AMI to include additional software or configurations:

<Steps> <Step title="Connect via RDP"> Use the default credentials: - **Username**: `testdriver` - **Password**: `wwv9uJ0sqlulbN3` </Step> <Step title="Change the Password"> **Critical**: Run the password rotation script immediately: ```powershell C:\testdriver\RotateLocalPasswords.ps1 ``` Save the new password securely. </Step> <Step title="Install Your Software"> Install any additional dependencies, configure settings, or modify the environment as needed. </Step> <Step title="Create New AMI"> Use the AWS console or CLI to create an AMI from your modified instance. Update your workflow to use the new AMI ID. </Step> </Steps> <Warning> **Security**: Never use the default password in production. Always rotate passwords before creating custom AMIs. </Warning>

Security Best Practices

Network Security

• Restrict CIDR blocks — Only allow access from known IP ranges
• Use VPC endpoints — For private AWS service communication
• Enable VPC Flow Logs — For network monitoring

AWS Authentication

Use OIDC instead of long-term credentials for GitHub Actions:

permissions:
  id-token: write
  contents: read

steps:
  - name: Configure AWS credentials
    uses: aws-actions/configure-aws-credentials@v4
    with:
      role-to-assume: arn:aws:iam::123456789012:role/GitHubActionsRole
      aws-region: us-east-2

See GitHub's OIDC documentation for setup instructions.

Instance Security

• Terminate immediately after tests complete
• Monitor costs with AWS billing alerts
• Use least-privilege IAM roles
• Enable CloudTrail for audit logging

Troubleshooting

Instance Not Responding

• Check security groups — Verify required ports are open (RDP 3389, VNC 5900, TestDriver ports)
• Verify status checks — Ensure instance has passed AWS status checks
• Check AMI compatibility — Some instance types don't support certain AMIs

Connection Timeouts

• Verify network connectivity from CI runner to instance
• Check VPC routing and internet gateway configuration
• Confirm instance is in the correct subnet

AWS CLI Errors

• Validate credentials and permissions
• Check service quotas and limits
• Verify region consistency across all resources
