 /**
  * 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.
