### Question:
RateLimiterCounterCassandraProviderImpl implements
		RateLimiterCounterProvider { public void setRLCounter(final String key, int i) { RateLimiterPolicyModel activeRL = getOrCreateActiveRL(key); activeRL.setCount(i); activeRLDao.save(key, activeRL); } RateLimiterCounterCassandraProviderImpl(); Set<String> getActiveRLKeys(); void addActiveRL(final String key,
			final RateLimiterPolicyModel RateLimiterPolicyModel); boolean cointainKeyInActiveRL(final String key); void addActiveEffect(final String key,
			final RateLimiterPolicyModel RateLimiterPolicyModel); void removeActiveEffect(final String key); void incrementRLCounter(final String key); void setRLCounter(final String key, int i); void setRLTimestamp(final String key, final Date date); void setRLActive(final String key, boolean b); void setRLEffectDuration(final String key, final Long duration); void setRLRolloverPeriod(final String key, final Long rollover); void setRLEffect(final String key, final RateLimiterStatus effect); RateLimiterPolicyModel getActiveRL(final String key); void resetEffects();  }### Answer:
@Test public void testSetRLCounter() { providerImpl.setRLCounter(rl_key, 1); assertEquals("rl_key counter should be 1", 1, providerImpl.getActiveRL(rl_key).getCount()); providerImpl.setRLCounter(rl_key, 5); assertEquals("rl_key counter should be 5", 5, providerImpl.getActiveRL(rl_key).getCount()); }
