Cache Eviction not working

[the-wrangler17]

Cache eviction is not taking into account the scope and collection, only the bucket. The problem seems to be in the DefaultCouchbaseCacheWriter.clear(String) method.

public long clear(final String pattern) {
QueryResult result = clientFactory.getCluster().query(
"DELETE FROM " + clientFactory.getBucket().name() + " where meta().id LIKE $pattern",
queryOptions().metrics(true).parameters(JsonObject.create().put("pattern", pattern + "%")));
return result.metaData().metrics().map(QueryMetrics::mutationCount).orElse(0L);
}

the cacheEvict test case does not check that user1 is evicted. Only that user2 is not evicted.

@Test
void cacheEvict() {
	CacheUser user1 = new CacheUser(UUID.randomUUID().toString(), "first1", "last1");
	CacheUser user2 = new CacheUser(UUID.randomUUID().toString(), "first2", "last2");
	cache.put(user1.getId(), user1); // put user1
	cache.put(user2.getId(), user2); // put user2
	cache.evict(user1.getId()); // evict user1
	assertEquals(user2, cache.get(user2.getId()).get()); // get user2 -> present
}
