How do I execute a Playwright test from a JavaScript file without relying on the command line interface?

Answer

Running a Playwright Test from a JavaScript File

To run a Playwright test from a JavaScript file without using the CLI, you can create a custom script that imports and executes the test. Here's a step-by-step guide:

1. Install @playwright/test: First, make sure you have the @playwright/test package installed in your project. If not, install it using npm or yarn:

   npm install -D @playwright/test

2. Create a test file: Create a test file, for example, my-test.spec.ts, and write your test using the test object from @playwright/test:

   import { test } from '@playwright/test';
   
   test('Load ray.run homepage', async ({ page }) => {
     await page.goto('https://ray.run/');
     const title = await page.title();
     expect(title).toBe('Ray.run - Playwright Test Automation');
   });

3. Create a custom script: Create a new JavaScript file, for example, run-test.js, and import the runTests function from @playwright/test. Then, call this function with the test file path as an argument:

   const { runTests } = require('@playwright/test');
   
   (async () => {
     await runTests(['./my-test.spec.ts']);
   })();

4. Execute the custom script: Finally, run the custom script using Node.js:

   node run-test.js
