The Pulumi SDK test package for testing with mocks.
"""

# The mocks tests are in their own `test_with_mocks` package so they can be run separately
# from other tests in the `test` package. Otherwise, if the mocks tests were in the same
# package as other tests, the code that initializes the mocks and test resources would run
# during test discovery and impact the behavior of other tests due to modifying global state.
Fix Python mocks (#4074) The original version of this code caused inconsistencies in the event loop associated with a given thread. These changes elimintate the event loop shenanigans the mocks were trying to play by updating _sync_await to create an event loop if none exists in the current thread. It's possible that this will cause problems if the tests run on a different thread than the original program, as the tests are likely to end up waiting on outputs created by the program, which is not supported in Python. Also adds test coverage of the mocking/testing support in Python. 2020-03-13 05:09:47 +01:00			`# Copyright 2016-2018, Pulumi Corporation.`

Allow `pulumi.export` calls from unit tests (#4670) The previous attempt to allow this didn't actually allow it, so this is take two. As part of the previous attempt, I thought after tweaking the test I had observed the test failing, and then succeeding after making the product changes, but I must have been mistaken. It turns out that our existing mocks tests weren't running at all because of a missing `__init__.py` file. Once the missing `__init__.py` is added, the tests run, but other tests ("test mode" tests) fail because the code that creates the mocks and resources will run during test discovery, and setting the mocks modifies global state. To address the test issue, I've moved the mocks tests into their own `test_with_mocks` package that can be run separately from other tests. And addressed the original issue, by creating a root Stack resource if one isn't already present when the mocks are set. 2020-05-20 18:54:40 +02:00			`"""`
