# `StarView.Test`
[🔗](https://github.com/Neophen/star_view/blob/v0.7.0/lib/star_view/test.ex#L1)

Assertions for StarView SSE responses in `Plug.Test` / `Phoenix.ConnTest`
tests. Chunked SSE bodies accumulate on the test adapter; these helpers
parse them back into events.

    conn = Plug.Conn.put_req_header(conn, "content-type", "application/json")
    conn = post(conn, "/ds/my_app_web-counter_controller/increment", StarView.JSON.encode!(%{count: 0}))
    assert_patched_signals(conn, %{count: 1})
    assert_patched_element(conn, "#history")

# `assert_patched_element`

Asserts a `datastar-patch-elements` event targets `target` — either via
an explicit `selector` line or via an `id` attribute in the patched HTML
(pass the target as `"#the-id"` in both cases).
Returns the conn for piping.

# `assert_patched_signals`

Asserts a top-level subset of emitted signals. Nested values compare exactly.
Keys may be atoms
or strings; values compare against the JSON-decoded patch.
Returns the conn for piping.

# `patched_signals`

Combines all emitted signal patch documents, including `null` removals.
This inspects writes, not the browser's final state: it does not apply
`onlyIfMissing` against initial signals or remove null-valued keys.

# `sse_events`

Parses the SSE events from a conn (or raw body string) into a list of
`%{type: String.t() | nil, data: [String.t()]}`.

This parser understands StarView's own SSE output format (`event: ` /
`data: ` with a trailing space, LF line endings) — it is not a
general-purpose SSE parser.
