Chunks shared between entrypoints are deduplicated. Here, app1 and app2 share app.chunk.1.js.
{%
include test/case.md
test="asset_map/chunks_js"
test_case_name="chunks_js_include"
entrypoints="app1,app2"
%}
Missing entrypoints cause an error {% include test/case.md test="asset_map/chunks_js" test_case_name="chunks_js_include_missing" entrypoints="missing,app2" %}
You can even mix css and js chunks in your entrypoints array.
{%
include test/case.md
test="asset_map/chunks_js"
test_case_name="chunks_js_mixed"
entrypoints="app3,app2"
%}
