testFillingCache()

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	$cacheMaxEntries	Maximum entry the created cache will hold
int	$entryToFill	Number of entries to insert in the created cache.

testReplaceExistingKeyInAFullCacheShouldBumpToTop()

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).

testReplaceExistingKeyShouldBumpEntryToTop()

ProcessCacheLRUTest::testReplaceExistingKeyShouldBumpEntryToTop

(

)

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

Should bump it to the top.
