Example 36 with Parameters

use of junitparams.Parameters in project aion by aionnetwork.

the class TrieTest method testInsertUpdateDeleteGet.

/**
 * Tests correct retrieval using {@link TrieImpl#get(String)} after an
 * initial insert with {@link TrieImpl#update(String, String)} and after a
 * sequential update using {@link TrieImpl#update(String, String)}. Uses
 * diverse combinations of keys and values from
 * {@link #keyValue1Value2Parameters()}.
