 * @(G2)@ All tests by default are run against a special Ably sandbox environment.  This environment allows apps to be provisioned without any authentication that can then be used for client library testing. Bear in mind that all apps created in the sandbox environment are automatically deleted after 60 minutes and have low limits to prevent abuse. Apps are configured by sending a @POST@ request to @https://sandbox-rest.ably.io/apps@ with a JSON body that specifies the keys and their associated capabilities, channel namespace rules and any presence fixture data that is required; see "ably-common test-app-setup.json":https://github.com/ably/ably-common/blob/main/test-resources/test-app-setup.json. Presence fixture data is necessary for the REST library presence tests as there is no way to register presence on a channel in the REST library
 * @(G3)@ Testing statistics can be tricky due to timing issues and slow test suites as a result of sending requests to generate statistics.  As such, we provide a special stats endpoint in our sandbox environment that allows stats to be injected into our metrics system so that stats tests can make predictable assertions.  To create stats you must send an authenticated @POST@ request to the stats JSON to @https://sandbox-rest.ably.io/stats@ with the stats data you wish to create. See the "JavaScript stats fixture":https://github.com/ably/ably-js/blob/4e65d4e13eb8750a375b9511e4dd059092c0e481/spec/rest/stats.test.js#L8-L51 and "setup helper":https://github.com/ably/ably-js/blob/4e65d4e13eb8750a375b9511e4dd059092c0e481/spec/common/modules/testapp_manager.js#L158-L182 as an example
