Write a Playwright test using AWS Lambda

  1. Create a Playwright Test Script:

Write your Playwright test script in a Node.js environment. Here's a simple example using Playwright to open a webpage and take a screenshot:
`const { chromium } = require('playwright');

exports.handler = async (event) => {
let browser;
try {
browser = await chromium.launch();
const context = await browser.newContext();
const page = await context.newPage();

await page.goto('https://example.com');
await page.screenshot({ path: '/tmp/example.png' });

await browser.close();

return {
  statusCode: 200,
  body: JSON.stringify({ message: 'Screenshot taken!' }),
};
Enter fullscreen mode Exit fullscreen mode

} catch (error) {
console.error('Error:', error);

return {
  statusCode: 500,
  body: JSON.stringify({ error: 'Internal Server Error' }),
};
Enter fullscreen mode Exit fullscreen mode

} finally {
if (browser) await browser.close();
}
};`

  1. Package Dependencies:

Since AWS Lambda has limited space for dependencies, you should use a tool like serverless or AWS SAM to package your Lambda function along with its dependencies. Ensure that you package Playwright and any other required Node.js modules.

3.Deploy to AWS Lambda:

Use AWS CLI or a deployment tool like serverless or AWS SAM to deploy your Lambda function to AWS.

4.Configure Lambda Function:

In the AWS Lambda console, set up your function. You'll need to configure the following:

** Runtime:** Node.js (Choose the version according to your script's requirements).
** Handler:** The name of your Lambda function and the exported function (e.g., filename.handler).
Memory: Set memory as per your requirements.
** Timeout:** Set the timeout duration for your function. Ensure it's long enough to complete your Playwright test.
** Execution Role:** Create an IAM role that allows the Lambda function to execute other AWS services and resources as needed.

5.Create an API Gateway (Optional):

If you want to trigger your Lambda function via an HTTP request, you can create an API Gateway and configure it to invoke your Lambda function.

6.Testing the Lambda Function:

You can now test your Lambda function by invoking it either through the AWS Lambda console or by making an HTTP request if you set up API Gateway.
