# `PhxDemo.Fixtures`
[🔗](https://github.com/thenatespack/phoenix_demo/blob/main/lib/phx_demo/fixtures.ex#L1)

Finds the files that `upload/4` and `drop_files/4` attach.

Relative paths resolve from `test/demos/fixtures/` (change it with
`config :phx_demo, :fixtures_dir, "path"`, relative to the project root). A
leading `fixtures/` is accepted too, so `"report.pdf"` and
`"fixtures/report.pdf"` mean the same file. Absolute paths are used as-is.

`PhxDemo.Case` checks every literal path in a demo before the browser
starts (see `literal_paths/1`), so a missing file fails the run up front.
Paths computed at runtime are checked when the step runs.

# `check!`

Raises `PhxDemo.Env.Error` naming every missing file.

# `dir`

The fixtures directory, absolute.

# `literal_paths`

Fixture paths written literally in a demo's AST: the path argument of
`upload`, `drop_files`, `upload_audio` and `use_microphone` calls, piped or
not. Used at compile time.

    iex> ast = quote do
    ...>   conn |> upload("#doc", "a.pdf") |> drop_files("#zone", ["b.png", "c.csv"], picker: true)
    ...>   upload(conn, {:label, "Doc"}, "d.pdf")
    ...>   conn |> upload_audio("#a", "e.wav") |> use_microphone("f.mp3", loop: true)
    ...> end
    iex> ast |> PhxDemo.Fixtures.literal_paths() |> Enum.sort()
    ["a.pdf", "b.png", "c.csv", "d.pdf", "e.wav", "f.mp3"]

# `path`

The absolute path for a fixture, without checking that it exists.

    iex> PhxDemo.Fixtures.path("/tmp/a.pdf")
    "/tmp/a.pdf"
    iex> PhxDemo.Fixtures.path("fixtures/a.pdf") == PhxDemo.Fixtures.path("a.pdf")
    true

# `resolve!`

Absolute paths for one or many fixtures. Raises `PhxDemo.Env.Error` if any is missing.
