Developer Quick Test Snippets

Copy and paste these pre-configured commands to test uploads, API endpoints, and browser automation:

1. Direct Download via cURL

curl -O https://samplepdf.org/files/sample-1mb.pdf

2. Python (Requests) Upload Test

import requests

url = "https://your-api.example.com/api/upload"
with open("sample-1mb.pdf", "rb") as f:
    response = requests.post(url, files={"file": ("sample-1mb.pdf", f, "application/pdf")})

print(f"Status: {response.status_code}")
assert response.status_code in [200, 201, 413]  # Expect success or Payload Too Large

3. Playwright E2E File Upload

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

test('verify 1 MB Sample PDF Download upload limit', async ({ page }) => {
  await page.goto('https://your-app.example.com/upload');
  await page.setInputFiles('input[type="file"]', 'sample-1mb.pdf');
  await page.click('button[type="submit"]');
  // Add your expected assertion below:
  // await expect(page.locator('.toast')).toContainText('File uploaded successfully');
});

Why Test With This Specification?

Many file-upload forms, profile photo attachments, and document processors set a 1 MB file size boundary. A test file calibrated to exactly 1,048,576 bytes guarantees accurate threshold testing.

Boundary Condition Verification: Test whether limits like ≤ 1 work correctly or fail with off-by-one errors.
Error Message Validation: Confirm that exceeding limits triggers a clear, user-friendly "File too large" validation alert.
Network Resilience: Evaluate upload timeouts and progress bars under throttled network conditions.

Frequently Asked Questions

Why test with a 1 MB sample PDF?

Many applications enforce a 1 MB upload ceiling or use 1 MB as a performance benchmark. Testing with a file that is exactly 1,048,576 bytes verifies whether your boundary validation accepts or rejects files at the exact limit without rounding errors.

Does this 1 MB PDF contain personal or confidential data?

No. The file is a synthetic test document containing only standard typography and clean padding. It contains no personal names, account numbers, passwords, or hidden tracking scripts.

How can I verify the file size after downloading?

On macOS/Linux run 'ls -l sample-1mb.pdf' or 'wc -c sample-1mb.pdf' to see exactly 1,048,576 bytes. On Windows, right-click and check 'Size' in Properties.

Can I use the direct URL in automated CI/CD test pipelines?

Yes. The direct URL https://samplepdf.org/files/sample-1mb.pdf is permanent and CORS-friendly. You can download it directly in automated test suites with curl, wget, or Playwright.
