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 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.

Nestor Soriano 8a7d955253 Improvements on the code hacker.
- 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.

Nestor Soriano 57845ef8b8 All code hacking files moved to src\Testing folder. 2020-05-20 09:56:25 +02:00
Nestor Soriano 1a68abbc28 Miscellaneous code hacking fixes:
- 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.
