/**
 * Enough of WordPress to test the parts that do not need it.
 *
 * The classes worth testing hardest — the curve, address encoding, the signing
 * envelopes, URL-to-path mapping — are the ones with no WordPress in them.
 * Standing up a full WordPress test install to exercise them would make the
 * suite slow enough that nobody runs it, which is the failure mode that
 * matters most for cryptographic code.
 *
 * So this file supplies the handful of core functions those classes touch, and
 * the suite runs under plain PHP in well under a second. Anything that needs
 * real WordPress — the auth flow, the queue, the admin screens — is tested by
 * installing the fork, which docs/testing.md describes.
