Description

Test Content-Disposition header parsing. Verify filename extraction including special characters and encoding.

Test Scenario

// Playwright: Parse Content-Disposition
const response = await request.get('/api/v1/files/download?format=csv');

const disposition = response.headers()['content-disposition'];
expect(disposition).toContain('attachment');

// Parse filename from header
const filenameMatch = disposition.match(/filename="?([^";]+)"?/);
expect(filenameMatch).not.toBeNull();

const filename = filenameMatch[1];
expect(filename).toMatch(/\.csv$/);
console.log('Downloaded:', filename);
Endpoint/api/v1/files/download?format=csv

Testing Tips

  • •Content-Disposition can be inline or attachment
  • •Filename may be URL-encoded for special chars
  • •Check for filename* parameter (RFC 5987)
  • •Handle missing Content-Disposition gracefully
// Playwright API Testing - File Operations
import { test, expect } from '@playwright/test';


test('File download', async ({ request }) => {
  const response = await request.get('/api/files/download/report.pdf');


  expect(response.ok()).toBeTruthy();
  expect(response.headers()['content-type']).toContain('application/pdf');


  const buffer = await response.body();
  expect(buffer.length).toBeGreaterThan(0);
});
