The output displays “timeout”.
Details
Save as example.html beside jquery.min.js (jQuery 3.5.1). The browser test uses that local library and checks the resulting behavior. The timeout option bounds how long the client waits.
Serve the page over HTTP with the endpoint shown. The verification container provides a local fixture API; no external service is contacted.
Tested on Ubuntu 24.04.5 LTS · · Chromium 141.0.7390.37 · libc6 2.39-0ubuntu8.9; Playwright 1.56.0; jQuery 3.5.1
Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Unprivileged snippet process, external networking disabled, read-only root filesystem, and a fresh temporary working directory. HTTP examples use a same-origin loopback fixture API inside this container. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.

Test input setup
These are the prepared inputs used by the test harness. See Details above for the prerequisites and how to run this example.
# No input files required.
Observed standard output
Expected output describes the rendered page. The standard-output record below is the browser test harness receipt; the additional assertions check the result and interactions.
Handle a request timeout: browser checks passed.
Exit code: 0. Standard error: empty. Validation: Shape/content assertions. System-dependent values above are one recorded run.
Additional assertions that passed
Checks recorded by the test harness. Where Python assertions are shown, browser cases use Playwright and simulator cases may inspect pin transitions: result.stdout is captured output, work is the temporary directory, and Path is pathlib.Path. The harness also imports json and csv.
await page.wait_for_function('document.querySelector("output").textContent === '+'timeout'.__repr__())
assert await page.locator('output').inner_text()=='timeout'
