/**
 * These tests exist to ensure a seamless upgrade path from 3.x to 4.x. If any
 * of these tests fail in 4.x, then it's because we've changed functionality
 * in such a way that compatibility with 3.x is broken.
 *
 * Naturally, there are some BC-breaks between 3.x and 4.x, but these tests
 * ensure that the base-level functionality that satisfies 80% of use-cases
 * does not change. The remaining 20% of use-cases should refer to the README
 * for details on the easiest path to transition from 3.x to 4.x.
