Android Test
============

A gradle module for running Android instrumentation tests on a device or emulator.

1. Add an Emulator named `pixel5`, if you don't already have one

```
$ sdkmanager --install "system-images;android-29;google_apis;x86"
$ echo "no" | avdmanager --verbose create avd --force --name "pixel5" --device "pixel" --package "system-images;android-29;google_apis;x86" --tag "google_apis" --abi "x86"
```

    int CLIENT_UPN_TYPE = 0xC;
    /**
     * Buffer type for client claims information.
     */
    int CLIENT_CLAIMS_TYPE = 0xD;
    /**
     * Buffer type for device information.
     */
    int DEVICE_INFO_TYPE = 0xE;
    /**
     * Buffer type for device claims information.
     */
    int DEVICE_CLAIMS_TYPE = 0xF;

    /**
     * Flag for extra SIDs in logon information.
     */
    int LOGON_EXTRA_SIDS = 0x20;

And you can also declare body parameters as optional, by setting the default to `None`:

{* ../../docs_src/body_multiple_params/tutorial001_an_py310.py hl[18:20] *}

/// note

Notice that, in this case, the `item` that would be taken from the body is optional. As it has a `None` default value.

///

## Multiple body parameters { #multiple-body-parameters }

# Path Operation Configuration { #path-operation-configuration }

There are several parameters that you can pass to your *path operation decorator* to configure it.

/// warning

Notice that these parameters are passed directly to the *path operation decorator*, not to your *path operation function*.

///

## Response Status Code { #response-status-code }

You can define the (HTTP) `status_code` to be used in the response of your *path operation*.
