How do I run specific projects in Playwright using the command line?

Answer

Sure, you can define projects that won't run by default in @playwright/test. These projects only run when you specify them on the command line.

Configuring Projects

Projects are configured in the playwright.config.ts file. Each project has a unique name and specific configuration options.

// playwright.config.ts
import { PlaywrightTestConfig } from '@playwright/test';

const config: PlaywrightTestConfig = {
  projects: [
    {
      name: 'staging',
      // other configuration options...
    },
    {
      name: 'production',
      // other configuration options...
    },
  ],
};

export default config;

Running Specific Projects

To run a specific project, use the --project command line option followed by the project name.

npx playwright test --project=staging

This command will only run the tests associated with the "staging" project.

Why Use Projects?

Projects give you control over which tests to run and under what conditions. You can define multiple projects with different configurations such as different timeouts, retries, or even against different environments like staging and production.

Remember, @playwright/test runs all projects by default. But with the --project command line option, you can choose which project(s) to run.
