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.

Fix unit test problems in PHP 7.0.
This includes removing two array_merge and array_merge_eecursive
statements in the code hacker, that apparently were working differently
in PHP 7.0.

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 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.

Nestor Soriano c1ed403dd0 Add `@public` to `FunctionsMockerHack`.
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.

Nestor Soriano bfda3f9938 Code hacker resdesign for single-load of code files.
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.

Nestor Soriano 2a68bb018d Move testing tools to the tests/Tools directory
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.
