test_static_mocks_can_be_used_via_injected_legacy_proxy_and_woocommerce_object
was failing in PHP 7.0, this replacement fixes it.
Suspected cause: https://bugs.php.net/bug.php?id=76505
- src/README.md largely expanded
- tests/README.md expanded
- includes/README.md added
- src/Internal/REAMDE.md added
src/README.md and includes/README.md have TODO placeholders to add
guidelines regarding to actions and filters.
If a class name is passed as a concrete, check that the class
constructor is public if it exists. If another type of concrete is
passed, check that it's valid (a callback or an object).
Also update the autoloader to check if the class file exists,
otherwise class_exists fails if a namespaced class doesn't exist.
The following methods are added and can be invoked using `WC()`,
they just redirect to the same methods in LegacyProxy:
call_function
call_static
get_instance_of
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.
- `get_instance_of` accepts now arguments to be passed to the
class constructor if necessary.
- `get_special_instance_of` method removed, instead, now if a method
named `get_instance_of_<lowercased class name>` exists in the class,
it is used to get the instance of the class.
- A couple more unit tests added.
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.
At some point the 'change_stock' key is assumed to be present
in the request data, but it might not. Fixed to test for existence
before using the value.
The test added checks that stock status of variations when saving
a variable product is changed or not appropriately depending on
the request data supplied.
Those methods are a convenient replacement for
"this->factory->user->create". Tests that were using that to
simulate user login have been modified to use the new methods.
Some of our endpoints don't have an "<id>" parameter but we're expecting one in the CLI. Since the `id` is already part of the supported IDs we don't actually need this since it will pull it from the route.
In practice having the response class contained within the error feels a little backwards. We can instead have a structured APIError model that is contained in the APIResponse and have a consistent response format to consume.
When a product is saved its validate_props method is invoked,
and this recalculates the stock_status property based on whether
the product manages stock or not, the stock quantity, and the
value of the woocommerce_notify_no_stock_amount option.
In the case of variable products, and when stock is managed, the stock
was set to "instock" when the current stock was enough, but only
if the "stock_quantity" property was in the list of changed properties
for the object (the method in the base product class doen't check
for changed properties). This is a problem because the
wc_update_product_stock function updates stock_quantity but via direct
database modification, and thus stock_quantity isn't considered
modified. Therefore stock modifications via wc_update_product_stock
don't update stock_status on the product (e.g. when going from 0 to 1
after a refund the stock status will remain as "outofstock").
The fix consists of removing the check for changed properties since
it's not done anyway in the other cases (when stock is below the
woocommerce_notify_no_stock_amount threshold) nor in the base class.
Also, validate_props is refactored for readabiliyy, and an useless
set_stock_status() call placed right before save()
in wc_update_product_stock is removed.
One of the problems with synchronous webhooks is that they are executed as soon as the related action is. Since we may call an action multiple times in the process of updating something, this causes only the first action to trigger the hook. This differs from asynchronous execution because in that case, the web hook will be executed after the entire request has completed.
We've hid the use of Axios behind a service so that we're able to easily mock it out in factories as well as handle the creation and configuration of the client. This will make it easier on consumers in that they won't have to worry about things like authentication when using the API.
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.
Right now, when a product having a parent (e.g. a variation having a
parent variable product) is saved, wc_deferred_product_sync is
executed so that product sync is performed at the end of the request.
This commit implements the same when the product is deleted.
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.
- Fix how CodeHackerTestHook::executeBeforeTest parses the test name,
to account for warnings and tests with data sets.
- CodeHackerTestHook now includes a executeAfterTest hook that
disables the code hacker (needed to prevent it from inadvertently
altering further tests). Also, clear_hacks is executed in
executeBeforeTest for the same reason.
- CodeHacker gets restore, clear_hacks and is_enabled methods
to support the changes in CodeHackerTestHook.
- FunctionsMockerHack fixed so that it doesn't modify strings
that are class method definitions.
- Added the WC_Unit_Test_Case::file_copy method, it must be used
instead of the PHP built-in "copy" in tests, otherwise tests
that run with the code hacker active will fail.
This is something to investigate.
Now @hack class and method annotations can be used to register
code hacks as an alternative to using before_ methods.
The syntax is /* @hack HackClassName param1 param2 */
where parameters will be passed to the class constructor.
If the class name ends with "Hack", then that suffix can be
omitted (e.g. "Foo" can be specified instead of "FooHack").
The "code hacker" is a class that hooks on filesystem events
(using stream_wrapper_unregister) in order to allow for dynamically
modifying the content of PHP code files while they are loaded.
The code hacker class allows registering hacks, which are
functions that take source code as input and return the modified code.
A hack can be a standalone function or a class with a "hack" method.
A few hacks are provided off the shelf. One allows mocking standalone
PHP functions (WP, WOO or not), another one allows mocking static
methods, and there's the one that removes the "final" qualifier
from a class definition. This helps unit testing stuff that would
otherwise be quite hard to test.
