Spring: right way to mock beans

Question

I have: beans like

<bean id="abstractBean" class="com.package.MyBean" abstract="true"/>

<bean id="heirBean" parent="abstractBean">
    <property name="someProperty" ref="anotherBean">
</bean>

Question: How to mock heirBean ? Or in other words how to mock abstractBean ?

---

======================== OPTIONAL PART OF QUESTION ==============================

How do I tried to do that [with exception]:

<bean id="abstractBean" class="MockFactoryBean">
    <property name="type" value="com.package.MyBean"/>
</bean>

MockFactoryBean.java

public class MockFactoryBean<T> implements FactoryBean<T> {
    private Class<T> type;

    public void setType(Class<T> type) {
        this.type = type;
    }

    @Override
    public T getObject() throws Exception {
        return Mockito.mock(type);
    }

    @Override
    public Class<T> getObjectType() {
        return type;
    }

    @Override
    public boolean isSingleton() {
        return true;
    }

}

Problem: I can't set fields of mock.

Answer 1

有一个框架可让您向Spring xml文件添加模拟功能-https: //bitbucket.org/kubek2k/springockito/wiki/Home

Answer 2

Generally, you don't mock parent beans, you mock each bean you want to mock.

As I understand your problem:

• you have many beans
• than use some common functionality
• you want to mock that common functionality

While the theory generally discourages refactoring for testing, the specific needs of the tests allow you to see the ways you could refactor your code.

I'd propose:

• moving the common functionality to the separate interface+implementation
• injecting that functionality to all your beans that use it
• mock that common functionality

Therefore you replace inheritance with usage , which allows you much more flexibility.

Answer 3

I would use the profile concept of spring; from spring 3.2.X there is the "profile" concept in Spring and you can use it to mock your bean for test scope
