How do I set custom HTTP headers for a specific test in Playwright?

Answer

Sure, you can set custom HTTP headers for a specific test in Playwright. Here's how you do it:

First, make sure you've got your Playwright configuration file (playwright.config.ts). This is where you set global options for all tests.

But for a specific test, you'll need to modify the test file itself. Let's say it's my-test.spec.ts. You'll need to import the necessary dependencies:

import { test } from '@playwright/test';

Before defining your test case, use the test.use() method. This lets you pass in an object with the options you want. For extraHTTPHeaders, you'd do it like this:

test.use({
  extraHTTPHeaders: {
    'Custom-Header': 'Value',
  },
});

Then, you can define your test case using the test() function:

test('My Test', async ({ page }) => {
  // Your test code goes here...
});

This way, Playwright will apply the options you set with test.use() to this specific test case. In this example, it sets a custom header named 'Custom-Header' with a value of 'Value'.

Remember, you can customize each test with different options using test.use(). This lets you use different extraHTTPHeaders for each scenario.
