[tests] Add Jest and PHPUnit coverage for the Product Results Count block (#68662)
test(blocks): Add lower-layer coverage for Product Results Count
The Product Results Count block had one browser test and nothing
underneath it. This adds both layers it was missing and removes
nothing.
A Jest suite covers the editor side: that the block registers its real
editor placeholder and a dynamic save callback.
A new PHPUnit class covers the rendered output, which is where this
block's logic actually lives. It asserts the paginated result count
rendered with a query context, and the default router region used when
no query context is supplied.
The block's browser test is kept exactly as it is. The migration
branch deletes it; this branch does not, for the same reason as the
Catalog Sorting batch. That test asserts on the editor canvas, and
moving it to the rendered archive looks like an improvement until you
find that whether this block appears there depends on
wc_blocks_use_blockified_product_grid_block_as_template, which five
specs in tests/e2e set to false and none restores. A front-end
assertion would report what ran before it.
Its render() is also worth noting for anyone tempted to assert on the
wrapper: it opens a div unconditionally and only then buffers
woocommerce_result_count(), so the wrapper is present even when the
count is empty. Any front-end check has to assert the text.
Consolidates the mega-branch slices:
- Slice 091
