Example 8 with SmallBlock

use of io.nuls.protocol.model.SmallBlock in project nuls by nuls-io.

the class TemporaryCacheManagerTest method cacheSmallBlock.

/**
 * 测试小区快的缓存处理流程：
 * 1. 先测试放入缓存，不出现异常视为成功
 * 2. 测试获取刚放入的小区快，获取的结果不能为空且和刚仿佛的是相同内容
 * 3. 测试删除之前放入的小区快，删除后再获取应该得到null
 * 4. 重新把小区快放回缓存中，调用清理方法，清理后缓存中应该没有任何小区块或者交易
 * test the cache processing process of the smallblock:
 * 1. The first test is put into the cache, and no exceptions are deemed to be successful.
 * 2. Test to get the newly inserted smallblock fast, the results can not be empty and the same content as if it is just as if.
 * 3. Before the test is deleted, the cells should be put into the smallblock quickly. After deleting, it should be null.
 * 4. Reattach the smallblock to the cache, call the cleaning method, and there should be no blocks or transactions in the cache.
