问题描述
我想用make db连接测试类。我想测试的类在构造函数 Connection 类中接受为param。我想将mock对象传递给构造函数。你能告诉我一个好的框架，例子如何模拟数据库连接？
I want to test class with make db connection. Class that I want to test accept as param in constructor Connection class. I want to pass mock object to the constructor. Can you tell me good framework with example how to mock db connection?
推荐答案
你可以使用，它支持的。一般的模拟框架，如也可以使用，但JDBC是一组互相返回的接口，因此手工模拟将是硬。亲眼看看：
You can use MockRunner, which has support for JDBC. General mocking frameworks like Mockito will also work, but JDBC is a set of interfaces returning each other so hand-mocking will be hard. See for yourself: How to stub/mock JDBC ResultSet to work both with Java 5 and 6?
然而，模拟JDBC是如此脆弱和冗长（无论你使用哪种工具），我建议在一些瘦DAO层中抽象JDBC访问（参见 @duffymo answer）或者寻找内存数据库，如。
However mocking JDBC is so brittle and verbose (no matter which tools you use) that I would either suggest abstracting JDBC access within some thin DAO layer (see @duffymo answer) or go for in-memory database like H2.
