How do I configure multiple web servers for different projects in Playwright's .config file?


Sure, you can definitely set up different web servers for each project in the .config file with Playwright. It's as simple as providing an array of webServer configurations. Each object in this array represents a separate web server or background process you want to launch for your tests.

Here's an example:

module.exports = {
  projects: [
      name: 'Project 1',
      webServer: {
        command: 'npm run start',
        port: 3001,
        timeout: 120 * 1000,
        reuseExistingServer: true,
      name: 'Project 2',
      webServer: {
        command: 'npm run server',
        port: 3002,
        timeout: 120 * 1000,
        reuseExistingServer: true,

In this example, we have two projects each with its own web server. The command property is the shell command to start the server, port is where it's expected to appear, timeout is the duration before timing out, and reuseExistingServer tells Playwright whether to reuse an existing server if one is available.

Remember, each project can have its own configurations like timeouts, retries, and filters for running specific tests. So, you can associate specific projects with their respective web servers by configuring them accordingly.

This way, you can test against different environments or scenarios using distinct web servers without needing separate configuration files. It's all about flexibility with Playwright!
