Mobly Release 1.12: New Snippet Base Client and a New pre_run Stage

This release introduces the new generic Mobly snippet base client and the new Android snippet client built on top. The new snippet base enables us to better scale Mobly snippets across various platforms.

The old Android snippet client is now considered deprecated, and will be removed in the following release. Please update your code accordingly:

  • snippet_client -> snippet_client_v2
  • snippet_event -> mobly.snippet.callback_event
  • callback_handler -> callback_handler_v2

The generate_setup_tests stage is renamed to pre_run to better reflect its true role: steps that happen before all the test case methods are finalized. This is a pure rename with no functional changes. Please migrate your code as the generate_setup_tests stage will stop working completely in the next release.

New

  • Added the new Mobly snippet base client.
  • Added the new Android snippet client v2 based on the new base client.
  • Support changing Mobly's logger level to DEBUG via cli arg.
  • Termination signal type is now included in result records.

Breaking Changes

  • The old Android snippet client is deprecated.
  • The generate_setup_tests stage is now pre_run.

Fixes

  • Various issues in the Android snippet client.
