Schauen wir uns an, wie wir das machen können.

## pytest.mark.anyio

Wenn wir in unseren Tests asynchrone Funktionen aufrufen möchten, müssen unsere Testfunktionen asynchron sein. AnyIO stellt hierfür ein nettes Plugin zur Verfügung, mit dem wir festlegen können, dass einige Testfunktionen asynchron aufgerufen werden sollen.

## HTTPX

Let's look at how we can make that work.

## pytest.mark.anyio

If we want to call asynchronous functions in our tests, our test functions have to be asynchronous. AnyIO provides a neat plugin for this, that allows us to specify that some test functions are to be called asynchronously.

## HTTPX

func makeFromLiteral(lit string, kind syntax.LitKind) constant.Value {
	return constant.MakeFromLiteral(lit, kind2tok[kind], 0)
}

var kind2tok = [...]token.Token{
	syntax.IntLit:    token.INT,
	syntax.FloatLit:  token.FLOAT,
	syntax.ImagLit:   token.IMAG,
	syntax.RuneLit:   token.CHAR,
	syntax.StringLit: token.STRING,

    It helps a lot during **development**, but you **shouldn't** use it in **production**.

  const auto assets_it = collection_def_map.find(kSavedModelAssetsKey);
  if (assets_it == collection_def_map.end()) {
    return absl::OkStatus();
  }
  const auto& any_assets = assets_it->second.any_list().value();
  for (const auto& any_asset : any_assets) {
    AssetFileDef asset_file_def;
    TF_RETURN_IF_ERROR(
        ParseAny(any_asset, &asset_file_def, "tensorflow.AssetFileDef"));

В частности, вы можете напрямую использовать <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a> в тех проектах, где требуется более сложная логика работы с конкурентностью.

In particular, you can directly use <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a> for your advanced concurrency use cases that require more advanced patterns in your own code.
