 The QUnit reorder feature was inspired by Kent Beck, who designed a similar mechanism in JUnit Max for Eclipse. <sup>[[1]](https://topenddevs.com/podcasts/javascript-jabber/episodes/050-jsj-qunit-with-jorn-zaefferer) [[2]](https://www.youtube.com/watch?v=g9ykvSI0gjg) [[3]](https://web.archive.org/web/20141018095913/http://junitmax.com/)</sup>

+When enabled QUnit will run tests in a [seeded-random order](https://en.wikipedia.org/wiki/Random_seed).
 
 Randomly ordering your tests can help identify non-atomic tests which either depend on a previous test or are leaking state to subsequent tests.
 
-If `seed` is boolean true (or set as URL query parameter without a value), then QUnit will generate on-demand a new random value to use as seed. You can then read the seed from `QUnit.config.seed` at runtime, and use it to reproduce the same test sequence later.
+The provided string will be used as the seed in a pseudo-random number generator to ensure that results are reproducible. The randomization will respect the [reorder](./reorder.md) option if enabled, such that previously failed tests still run first instead of being shuffled.
+
+If `seed` is set to `true` (or add `?seed` to the URL, without any value), then QUnit will generate a new random seed every time you run the tests. To reproduce a specific random sequence, access the seed from `QUnit.config.seed` via the console.
