The default functionality within the `ThemeSupport` class has an unintended
side-effect of breaking the existing default functionality within the
`wc_get_theme_support()` function. Since the default set in the support
class is prioritized over the one given to `ThemeSupport::get_option()`,
the WordPress options set in the Customizer are never used for images.
- Added the `ThemeSupport class`, with methods to add and get
theme support options.
- It also has a new `add_default_options` method that adds the
options under a `_defaults` key.
- The `WC_Twenty_*` classes now use `ThemeSupport` instead of
the `add_theme_support` function to define image and thumbnail sizes.
- The values are defined as default options.
- The `WC_Shop_Customizer` class now uses `ThemeSupport` instead of
`wc_get_theme_support` to check if image and thumbnail sizes UI
should be rendered.
- The check is made excluding default values.
With these changes the UI to change the image and thumbnail sizes
is hidden only if the options are added as non-defaults elsewhere.
Additional changes:
- The code of the `wc_get_theme_support` function is replaced with
a simple call to `get_option` in `ThemeSupport`.
- Added the utility class `ArrayUtil`.
After the League's Container package has been reintroduced, all the
code that implements the dependency injection mechanism in woocommerce
can be brought back as well.
Since reverting the PR at this point would be a mess I've gone ahead and removed the internals of the container. We should aim to keep the class since it's now part of our public API but it won't work as expected anymore. This is fine for now since we don't actually have anything in it!
Since we need to load all of these files before WooCommerce has initialized we can't rely on Composer to handle the autoloading. We should take this namespace out of Composer altogether and just have our test autoloader take care of it.
- Method and class renames.
- Removed unnecessary autoloader registration.
- Add a unit test for classes with non-object type hints
in constructor arguments.
Also:
- Make the methods in `AbstractServiceProvider` protected.
- Add an autoloader for files in the `tests/php/src` directory.
- Fix a bug in the provisional (?) autoloader.
- camelCase methods changed to snake_case for consistency with WP.
- Added a check in `ExtendedContainer::get` that throws an informative
exception if a non-namespaced class name is passed.
- `container->reset_resolved()` is called during unit testing bootstrap.
- Added some utility methods in `WC_Unit_Test_Case`.
- Added a new class `ExtendedContainer` that extends League's container.
- `add` modified to reject classes not in the root Woo namespace.
- Has two new methods, `replace` and `reset_resolved`.
- It's used as the underlying container instead of League's one
in `Container`, but the new methods are not exposed.
- At unit test bootstrap time the globally registered container is
replaced with the extended one that `Container` stores
(grabbed from private property using reflection).
- A new `MockableLegacyProxy` is added. It inherits from `LegacyProxy`
and allows to mock functions, static methods and legacy classes.
- The registeed `LegacyProxy` is replaced with the mockable version
during unit test bootstrap.
- A PHPUnit hook is added to reset the mockable proxy to its initial
state (so that nothing is mocked) before each test.
- `WC_Unit_Test_Case` gets helper methods to mock functions, static
methods and classes without having to retrieve the proxy class.
The mapping of the "Automattic\WooCommerce\Testing\Tools\" namespace
to the "tests/tools" directory is moved from manual registration
inside the tests bootstrap constructor to a declaration inside the
autload-dev section in composer.json.
The code hacker as originally designed, as a mechanism that allowed
to enable hacks at the individual test level, is flawed because it
assumes that code files are loaded before each test, but actually
the PHP engine loads code files only once.
Therefore this commit redesigns it so that the two existing main hacks,
the functions mocker and the static methods hacker, are applied
to all the relevant functions and classes at bootstrap time, and
mocks for each individual function/method can be registered at the
beginning of each test. See README for the full details.
The testing tools (only the code hacker at this time) have been moved
from 'src' to 'tests/Tools', since many opcode cache plugins
load the whole src folder in production.
Also, an extra autoloader is set in the tests bootstrap so that
the 'tests/Tools' directory corresponds, using PSR4, to the
'Automattic\WooCommerce\Testing\Tools' namespace.
- Add methods to temporarily disable and reenable the code hacker.
The code hacker is causing issues in some tests that perform
write operations to the local filesystem. Since this happens only
in a few cases, the easiest fix is to temporarily disable the
code hacker when that happens. This commit adds two new methods
for that in `WC_Unit_Test_Case`: `disable_code_hacker` and
`reenable_code_hacker`.
These methods use a disabling requests count so that the hacker
isn't enabled before it should. E.g. you call `disable`, then
a helper method that does `disable` and `enable`, then `enable` -
then only the last `enable` will have effect.
- `CodeHacker::add_hack` has now a boolean `persistent` parameter.
Persistent hacks won't be cleared by `clear_hacks`.
- `CodeHackerTestHook::executeAfterTest` will now disable the hacker
only if no persistent hacks are registered.
- The existing `file_copy` method is made static for consistency.
- `CodeHacker::restore` method renamed to `disable` for clarity.
The unit testing bootstrap loads and initializes WooCommerce, this
loads a bunch of code files that can't then be hacked in the test hooks.
A workaround is provided in this commit for the case of hacking
static methods. A new StaticWrapper class is created that allows
defining mock methods after the code file has been loaded.
This is applied to all classes from a fixed list in the bootstrap,
before WooCommerce is initialized. The list should be kept up to date
with the list of classes that require such workaround.
