You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: update_one.rs
    path of file: ./repos/grafbase/engine/crates/integration-tests/tests/mongodb
    
    the code of the file until where you have to start completion: use expect_test::expect;
use indoc::{formatdoc, indoc};
use integration_tests::{with_mongodb, with_namespaced_mongodb, GetPath};
use serde_json::json;

#[test]
fn id_not_found() {
    let schema = indoc! {r#"
        type User @model(connector: "test", collection: "users") {
          name: String!
        }
    "#};

    let response = with_mongodb(schema, |api| async move {
        let query = indoc!
    
fn id_not_found() {
    let schema = indoc! {r#"
        type User @model(connector: "test", collection: "users") {
          name: String!
        }
    "#};

    let response = with_mongodb(schema, |api| async move {
        let query = indoc! {r#"
            mutation {
              userUpdate(
                by: { id: "5ca4bbc7a2dd94ee5816238d" },
                input: { name: { set: "Derp" } }
              ) {
                matchedCount
                modifiedCount
              }
            }
        "#};

        api.execute(query).await
    });

    let expected = expect![[r#"
        {
          "data": {
            "userUpdate": {
              "matchedCount": 0,
              "modifiedCount": 0
            }
          }
        }"#]];

    expected.assert_eq(&response);
}
