Class: core_cache_testcase  - X-Ref

PHPunit tests for the cache API

setUp()   X-Ref
Set things back to the default before each test.


tearDownAfterClass()   X-Ref
Final task is to reset the cache system


get_expected_application_cache_store()   X-Ref
Returns the expected application cache store.

return: string

test_cache_config()   X-Ref
Tests cache configuration


test_windows_nasty_keys()   X-Ref
Tests for cache keys that would break on windows.


test_set_identifiers()   X-Ref
Tests set_identifiers fails post cache creation.

set_identifiers cannot be called after initial cache instantiation, as you need to create a difference cache.

test_default_application_cache()   X-Ref
Tests the default application cache


test_default_session_cache()   X-Ref
Tests the default session cache


test_default_request_cache()   X-Ref
Tests the default request cache


test_on_cache_without_store()   X-Ref
Tests using a cache system when there are no stores available (who knows what the admin did to achieve this).


run_on_cache(cache_loader $cache)   X-Ref
Runs a standard series of access and use tests on a cache instance.

This function is great because we can use it to ensure all of the loaders perform exactly the same way.

param: cache_loader $cache

test_definition_data_loader()   X-Ref
Tests a definition using a data loader


test_definition_overridden_loader()   X-Ref
Tests a definition using an overridden loader


test_definition_mappings_only()   X-Ref
Test the mappingsonly setting.


test_definition()   X-Ref
Test a very basic definition.


test_definition_simplekeys()   X-Ref
Test a definition using the simple keys.


test_application_ttl_negative()   X-Ref
Test a negative TTL on an application cache.


test_application_ttl_positive()   X-Ref
Test a positive TTL on an application cache.


test_session_ttl_positive()   X-Ref
Test a negative TTL on an session cache.


test_application_manual_locking()   X-Ref
Tests manual locking operations on an application cache


test_application_event_invalidation()   X-Ref
Tests application cache event invalidation


test_session_event_invalidation()   X-Ref
Tests session cache event invalidation


test_application_definition_invalidation()   X-Ref
Tests application cache definition invalidation


test_session_definition_invalidation()   X-Ref
Tests session cache definition invalidation


test_distributed_application_event_invalidation()   X-Ref
Tests application cache event invalidation over a distributed setup.


test_application_event_purge()   X-Ref
Tests application cache event purge


test_session_event_purge()   X-Ref
Tests session cache event purge


test_application_definition_purge()   X-Ref
Tests application cache definition purge


test_alt_cache_path()   X-Ref
Test the use of an alt path.
If we can generate a config instance we are done :)


test_disable_stores()   X-Ref
Test disabling the cache stores.


test_disable()   X-Ref
Test disabling the cache.


test_multiple_application_loaders()   X-Ref
Test that multiple application loaders work ok.


test_multiple_session_loaders()   X-Ref
Test that multiple application loaders work ok.


test_session_cache_switch_user()   X-Ref
Test switching users with session caches.


test_session_cache_switch_user_application_mapping()   X-Ref
Test switching users with session caches.


test_dual_session_caches()   X-Ref
Test two session caches being used at once to confirm collisions don't occur.


test_session_cache_switch_user_multiple()   X-Ref
Test multiple session caches when switching user.


test_application_locking()   X-Ref
Test application locking.


test_purge_stores_used_by_definition()   X-Ref
Test the static cache_helper method purge_stores_used_by_definition.


test_purge_routines()   X-Ref
Test purge routines.


test_purge_all_with_adhoc_caches()   X-Ref
Tests that ad-hoc caches are correctly purged with a purge_all call.


test_defaults_support_searching()   X-Ref
Test that the default stores all support searching.


test_static_acceleration()   X-Ref
Test static acceleration

Note: All the assertGreaterThanOrEqual() in this test should be assertGreaterThan() be because of some microtime()
resolution problems under some OSs / PHP versions, we are accepting equal as valid outcome. For more info see MDL-57147.

test_identifiers_have_separate_caches()   X-Ref
No description

test_performance_debug()   X-Ref
No description

test_static_cache()   X-Ref
No description

test_performance_debug_off()   X-Ref
No description

test_session_event_purge_same_second()   X-Ref
Tests session cache event purge and subsequent visit in the same request.

This test simulates a cache being created, a value being set, then the value being purged.
A subsequent use of the same cache is started in the same request which fills the cache.
A new request is started a short time later.
The cache should be filled.

test_session_distinct_storage_key()   X-Ref
Test that values set in different sessions are stored with different key prefixes.
