Merge "BumbleBluetoothTests: fix documentation" into main

```shell

cd $ANDROID_BUILD_TOP

source build/envsetup.sh

lunch aosp_cf_x86_64_phone-userdebug

lunch aosp_cf_x86_64_phone-trunk_staging-userdebug

acloud create # Create a remote instance using the latest know good build image.

acloud create --local-image # OR: Create a remote instance using a local image.

acloud create --local-image --local-instance # OR: Create a local instance using a local image.

```

Install virtual env:

```shell

sudo apt install virtualenv

```

Note: For Googlers, from an internal Android repository, use the `cf_x86_64_phone-userdebug` target

instead.

## Run existing tests

You can run all the existing BumbleBluetoothTests by doing so:

```shell

atest BumbleBluetoothTests

```

If you wish to run a specific test file:

```shell

atest BumbleBluetoothTests:<package_name>.<test_file_name>

atest BumbleBluetoothTests:android.bluetooth.DckTest

```

And to run a specific test from a test file:

```shell

atest BumbleBluetoothTests:<package_name>.<test_file_name>#<test_name>

atest BumbleBluetoothTests:android.bluetooth.DckTest#testDiscoverDkGattService

Note: The process might not shut down correctly when interrupted with a SIGINT (Ctrl + C) command.

This can leave behind a ghost process. To locate and terminate it, simply follow these steps:

```shell

ps aux | grep python3 # Identify the ghost process and its process id

kill <pid>

Let say we are creating a DCK test.

First, create your file under `p/m/Blueooth/frameworks/bumble/src/android/bluetooth` like so:

```shell

cd p/m/Bluetooth/frameworks/bumble/src/android/bluetooth

touch DckTest.kt # We usualy name our test file <test_suite_name>Test.kt/.java

```

Then add the minimum requirements:

```kotlin

import androidx.test.ext.junit.runners.AndroidJUnit4

Interactions over Bluetooth often involve callback mechanisms. Here, we're mocking the callback

with Mockito to verify later that expected events occurred.

```kotlin

val gattCallback = mock(BluetoothGattCallback::class.java)

```

### 5. Initiate and Verify Connection

To bond with Bumble, we initiate a connection and then verify that the connection is successful.

```kotlin

var bumbleGatt = bumbleDevice.connectGatt(context, false, gattCallback)

verify(gattCallback, timeout(TIMEOUT))
