Now, let's see how you could use that to return a custom response.

Let's say that you want to return an <a href="https://en.wikipedia.org/wiki/XML" class="external-link" target="_blank">XML</a> response.

You could put your XML content in a string, put that in a `Response`, and return it:

    if mod_name.startswith("tutorial003"):
        tags_expected = IsList("foo", "bar", check_order=False)
    else:
        tags_expected = ["foo", "bar", "foo"]

    response = client.put(
        "/items/123",
        json={
            "name": "Foo",
            "description": "A very nice Item",
            "price": 35.4,
            "tax": 3.2,
            "tags": ["foo", "bar", "foo"],

    void customOptions_arePropagated() {
        // Arrange
        Map<String, Object> opts = new HashMap<>();
        opts.put("useKeyTab", "true");
        opts.put("storeKey", "true");
        opts.put("principal", "******@****.***");
        StaticJAASConfiguration cfg = new StaticJAASConfiguration(opts);

        // Act

        bb.putShort((short) 52);

        bb.position(22);
        bb.put("\\\\path".getBytes(StandardCharsets.UTF_16LE));
        bb.putShort((short) 0);

        bb.position(38);
        bb.put("\\\\alt".getBytes(StandardCharsets.UTF_16LE));
        bb.putShort((short) 0);

        bb.position(52);
        bb.put("NODE".getBytes(StandardCharsets.UTF_16LE));
        bb.putShort((short) 0);

    }
