This PR deduplicates shared tests setup that was used across test files.
It attempts to centralise the setup into a single source of truth
implementation in `beets.test.helper`.
This works towards the eventual migration to `pytest` (#5361) making it
easier to replace the tests setup with `pytest` fixtures.
It builds upon the temporary files cleanup in #5345.
## Details
### Test setup
* Mostly duplicate test setup implementations in
`beets.test._common.TestCase` and `beets.test.helper.TestHelper` were
merged into a single implementation as
`beets.test.helper.BeetsTestCase`.
* Replaced `unittest.TestCase` and `beets.test.helper.TestHelper`
combination with `beets.test.helper.ImportTestCase`
* Refactored `test/test_plugins.py` removing duplicate import files
setup.
* Centralised setting up the database on disk.
* Centralised plugin test setup into `beets.test.helpers.PluginMixin`.
### Removals
* Around 1/3 of the removed lines correspond to the removal of `def
suite()` functions that were previously used for tests collection.
* Removed redundant `setUp` and `tearDown` methods from many test files
given that the functions that they performed had been centralised in
`beets.test.helper`.
* Removed redundant library initialisations
### Importing
* Centralised import directory creation (only gets created on the first
access).
* Deduplicated `_setup_import_session` implementations in
`TerminalImportSessionSetup` and `ImportHelper`.
* Merged `ImportHelper._create_import_dir` and
`TestHelper.create_importer` implementations into
`ImportHelper.setup_importer`.
* Merged various takes on import files prep into
`ImportHelper.prepare_albums_for_import` and
`ImportHelper.prepare_album_for_import`.
* Seeing that many tests used it, defined `AsIsImporterMixin` which
provides a method `run_asis_importer` to setup _asis_ (non-autotag)
importer and run it
A constant `preload_plugin` is used to disable loading the plugin in the
`setUp` initialisation, allowing the plugin to be loaded manually by the
tests.
Also added a cleanup instruction to remove listeners from configured
plugins, and removed this logic from several tests.
A couple of `ConfigTest` would previously fail locally since they
somehow depended on the local environment to work fine. This commmit
decouples them from any environment by setting up patching of the
environment variables properly.
Fixes#5229, is part of #5361 and relates to #5285.
I have to admit thsi was a fairly tough task - I initially assumed that
the problem lies
with how the tests are setup, and that we're probably missing some
`teardown_beets` calls
here and there.
Unfortunately, it was not so simple. I came across several issues that
gave rise to
leftover temporary files:
1. `fetchart`, `artresizer` and `play` handling of temporary files.
These plugins created
isolated temporary files outside of the directories that tests clean up.
You will find
I added a couple of functions (namely `get_module_tempdir`) that force
these plugins to
create files in directories determined by their module names. This way
we can clean up
after them using the new `CleanupModulesMixin`.
2. Tests that ran temporary directories setup twice, running
`_common.TestCase.setUp` and
`test.helper.TestHelper.setup_beets`. Both of these ran `self.temp_dir =
mkdtemp()`,
therefore the directories created by the initial setup persisted since
those have been
overridden and thus unreachable in the teardown. Here, I removed the
`setUp` calls, see
- `test/plugins/test_embedart.py`
- `test/test_importer.py`
- and `test/test_plugins.py` where `setup_beets` was called twice
3. `test/test_config_command.py` attempted to manage the temporary
directory by itself,
where I found that `tearDown` failed to remove the directory for four
tests. Could not
figure out the cause, and found that delegating this task to
`TestHelper` fixed the
issue.
4. Mediafile fixture removal depended on calling
`remove_mediafile_fixtures` method, which
`test/plugins/test_zero.py` failed to do. I made the fixtures to be
created within the
same `temp_dir` directory that gets removed in the teardown, so now they
are taken care
of automatically.
In summary, see the test modules that left files behind:
