// The Trust Token API (https://github.com/wicg/trust-token-api) allows clients
// to annotate outgoing requests with certain cryptographic state, by providing
// parameters alongside Fetch, XHR, and iframe-tag loads. These tests confirm
// that providing Trust Tokens parameters to each of these API entry points
// increments the corresponding Blink UseCounter. Although Trust Tokens is part
// of the web platform and the use counters are incremented in Blink, these
// tests live in //chrome because the Page Load Metrics framework, Chrome's way
// of listening for use counter updates, is not available in the content shell.
