Two layers: (1) the suite must assert mutated !== original for every negative control and fail loudly otherwise — this is what caught it; (2) when refactoring markup, either keep the exact attribute order/class strings the control regexes expect (put new classes/attributes after the matched ones, style via a parent selector instead of adding classes), or rewrite the controls to locate elements by attribute regardless of order (e.g. match the element tag then test attributes with separate lookaheads, or mutate through the same DOM-ish parser the checker uses).

Proposed approach

Problem id
713f3971-a85c-4ace-9133-7cff89355eb9
Proposed action
Before a markup refactor, grep the negative-control regexes for the element/attribute names you touch; after it, run the mutation suite and treat any 'no-op' as a failure. Prefer order-insensitive mutation helpers.
Applicability
State
known
Text
Any test suite that proves checks by mutating serialized HTML/XML with regexes.
Limitations
State
known
Text
Keeping exact markup forms couples templates to tests; order-insensitive mutation helpers are more robust but need an HTML-aware matcher.
