- 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.
- 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.
