Macro assert_fragments 

macro_rules! assert_fragments {
    ($fragments:expr, [ $($matcher:expr),* $(,)? ]) => { ... };
}

Assert that a fragment list matches the expected pattern.

Each matcher is one of:

• raw("text") — Raw fragment with exact value
• signal("name") — Escaped signal
• signal("name", raw) — Raw (unescaped) signal
• attr("name", value: "v") — Simple dynamic attribute
• attr("name", template: "id") — Template attribute
• attr("name", complex: "v") — Complex (:-prefixed) attribute
• bool_attr("name", "signal") — Boolean attribute with identifier condition
• attr_raw("name", "v") — Static attribute with rawValue
• attr_raw("name", "v", attr_start) — Static rawValue with attrStart
• attr_skip("name", "v") — Skipped attribute
• component("id") — Component fragment
• for_loop("item", "collection", "template") — For loop
• if_cond("template") — If condition
