ProcessCacheLRUTest::testDeleteOldKey ( )
ProcessCacheLRUTest::testFillingCache (   $cacheMaxEntries,
  $entryToFill,
  $msg = '' 
)

This test that we properly overflow when filling a cache with a sequence of always different cache-keys.

Meant to verify we correclty delete the older key.

ProcessCacheLRU::set provideCacheFilling

Parameters
int$cacheMaxEntriesMaximum entry the created cache will hold
int$entryToFillNumber of entries to insert in the created cache.

ProcessCacheLRUTest::testPhpUnitArrayEquality ( )

Highlight diff between assertEquals and assertNotSame.

ProcessCacheLRUTest::testRecentlyAccessedKeyStickIn ( )
ProcessCacheLRUTest::testReplaceExistingKeyInAFullCacheShouldBumpToTop ( )

This first create a full cache then update the value for the 2nd filled entry.

Given a cache having 1,2,3 as key, updating 2 should bump 2 to the top of the queue with the new value: 1,3,2* (* = updated).

ProcessCacheLRU::set ProcessCacheLRU::get

References $cache, and fillCache().

ProcessCacheLRUTest::testReplaceExistingKeyShouldBumpEntryToTop ( )

Create a cache with only one remaining entry then update the first inserted entry.

Should bump it to the top.
