Performing some tests:
Redis is connected: 1
Connection works in general
Success for method set(testKey, value)
Success for method setnx(testnxkey, value)
Success for method setex(testexkey, 5, value)
Success for method set(testKeyWithNx, value, array (0 => 'nx',))
Success for method set(testKeyWithEx, value, array ('ex' => 5,))
Initial expire seems to be set correctly
setIfNotExists works fine
expireIfKeyHasValue seems to work fine
Extending expire seems to be set correctly
expireIfKeyHasValue correctly expires only when the value is correct
Expire is still set which is correct
deleteIfKeyHasValue seems to work fine
List feature seems to work fine

Done
