试图使用jmockit来挖出一个javax.sql.DataSource类。有任何想法吗？jmockit嘲笑一个jacax.sql.DataSource
public class MyTest
{
@MockClass(realClass = DataSource.class)
public static class MockDataSource {
}
@Before
public void setup()
{
Mockit.setUpMocks(MockDataSource.class);
}
@Test
public void testCreateGetUpdateUser()
{
new NonStrictExpectations()
{
...
};
...
}
}
我在Eclipse中运行测试并拿到这个
