History

Renat Akhmerov 816bfd9dcc Refactor Mistral Engine * Introduced class hierarchies Task and Action used by Mistral engine. Note: Action here is a different than executor Action and represents rather actions of different types: regular python action, ad-hoc action and workflow action (since for task action and workflow are polymorphic) * Refactored task_handler.py and action_handler.py with Task and Action hierarchies * Rebuilt a chain call so that the entire action processing would look like a chain of calls Action -> Task -> Workflow where each level knows only about the next level and can influence it (e.g. if adhoc action has failed due to YAQL error in 'output' transformer action itself fails its task) * Refactored policies according to new object model * Fixed some of the tests to match the idea of having two types of exceptions, MistralException and MistralError, where the latter is considered either a harsh environmental problem or a logical issue in the system itself so that it must not be handled anywhere in the code TODO(in subsequent patches): * Refactor WithItemsTask w/o using with_items.py * Remove DB transaction in Scheduler when making a delayed call, helper policy methods like 'continue_workflow' * Refactor policies test so that workflow definitions live right in test methods * Refactor workflow_handler with Workflow abstraction * Get rid of RunExistingTask workflow command, it should be just one command with various properties * Refactor resume and rerun with Task abstraction (same way as other methods, e.g. on_action_complete()) * Add error handling to all required places such as task_handler.continue_task() * More tests for error handling P.S. This patch is very big but it was nearly impossible to split it into multiple smaller patches just because how entangled everything was in Mistral Engine.

Tempest Integration of Mistral

This directory contains Tempest tests to cover the mistral project.

To list all Mistral tempest cases, go to tempest directory, then run:

$ testr list-tests mistral

To run only these tests in tempest, go to tempest directory, then run:

$ ./run_tempest.sh -N -- mistral

To run a single test case, go to tempest directory, then run with test case name, e.g.:

$ ./run_tempest.sh -N -- mistral_tempest_tests.tests.api.v2.test_mistral_basic_v2.WorkbookTestsV2.test_get_workbook

Alternatively, to run mistral tempest plugin tests using tox, go to tempest directory, then run:

$ tox -eall-plugin mistral

And, to run a specific test:

$ tox -eall-plugin mistral_tempest_tests.tests.api.v2.test_mistral_basic_v2.WorkbookTestsV2.test_get_workbook
