Move code hacker resetting from BeforeTestHook to setUp
The code hacker needs to be reset before each test. This was done via
a couple of classes implementeing BeforeTestHook, those were registered
in phpunit.xml.

The problem is that the PHPUnit version used for WooCommerce unit test
has recently been changed from 7.5 to 6.5 for compatibility with
PHP 7.0, and hook classes were introduced in PHPUnit 7. Thus no hooks
were ran, the code hacker wasn't reset, that caused some functions
to remain hacked between tests, and this made some tests to fail.

The solution is to move the code hacker reset to the setUp method
in the base unit test class.

Nestor Soriano b71f876cba Reintroduce the dependency injection related code.
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.

Christopher Allford 358db5dc3e Removed the internals of the Container pending package conflict resolution
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!

Nestor Soriano c2e28b2b05 Replace array_merge_recursive in MockableLegacyProxy with custom code
test_static_mocks_can_be_used_via_injected_legacy_proxy_and_woocommerce_object
was failing in PHP 7.0, this replacement fixes it.

Nestor Soriano 1684ce08b3 Removed annotations as we're not going to use them. 2020-07-24 09:24:06 +02:00
Nestor Soriano 4ec143532c Adjustments in the LegacyProxy class.
- `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 to a couple of methods related to the code hacker.

Nestor Soriano d55f7d10f8 Some small imrpovements in the dependency injection framework:
- 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`.

Nestor Soriano ca9ed93b9a Added dependency injection infrastructure for unit tests:
- 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.
