/**
 * A unit test library for running groups of tests in a browser, instead of the
 * entire test file. This is especially used for large tests files that have
 * many subtests, so we can mark groups as failing at a finer granularity than
 * the entire test file.
 *
 * To use, import this file, and call [useHtmlIndividualConfiguration] at the
 * start of your set sequence. Important constraint: your group descriptions
 * MUST NOT contain spaces.
