docs/api/config/reorder.md
Allow re-running of previously failed tests out of order, before all other tests.
<table> <tr> <th>type</th> <td markdown="span">`boolean`</td> </tr> <tr> <th>default</th> <td markdown="span">`true`</td> </tr> </table>By default, QUnit will first re-run any tests that failed on a previous run. For large test suites, this can speed up your feedback cycle by a lot.
Note that this feature may lead to unexpected failures if you have non-atomic tests that rely on a very specific execution order. You should consider improving such tests, but this option allows you to disable the reordering behaviour.
When a previously failed test is running first, the HTML Reporter displays "Rerunning previously failed test" in the summary whereas just "Running" is displayed otherwise.
