有效应用的设计模式与灵活的单元测试途径

}

// OuterObjects.java
package com.factorymethod.demo;
public class OuterObjects implements BaseObjects {
public void func() {
System.out.println("OuterObjects.func");
}
}

// LogicToBeTested.java, code to be tested
package com.factorymethod.demo;
public class LogicToBeTested {
public void doSomething() {
BaseObjects b = createBase();
b.func();
}

public BaseObjects createBase() {
return newOuterObjects();
}
}

　　以下则是对应的 MockOuterObjects、MockFactory 以及单元测试的实现： // MockOuterObjects.java
package com.factorymethod.demo;
public class MockOuterObjects implements BaseObjects {
public void func() {
System.out.println("MockOuterObjects.func");
}
}

// MockLogicToBeTested.java
package com.factorymethod.demo;
public class MockLogicToBeTested extends LogicToBeTested {
public BaseObjects createBase() {
return new MockOutterObjects();
}
}

// LogicTest.java
package com.factorymethod.demo;
import junit.framework.TestCase;

public class LogicTest extends TestCase {
LogicToBeTested c;
protected void setUp() {
c =new MockLogicToBeTested();
}
public void testDoSomething() {
c.doSomething();
}
}
