Spock中填充

Question

我如何存根/模拟一个填充了一些稍后要用到的对象的void方法。

class RequestHelper{
public void populateOrderRequestBody(String product,String quantity,String profile, OrderType orderType){
    orderType.setProduct(product);
    orderType.setQuantity(Integer.parseInt(quantity));
    orderType.setUser(profile.getUserId());
} }

class ServiceClient{
RequestHelper rh;

public void docall(Order order){
    OrderType  orderType = FACTORY.CreateOrderType;
    rh.populateOrderRequestBody(order.getProduct(),order.getQuantity(),order.getProfile(),orderType);
    /**
    * some other code
    **/
}

public setRequestHelper(RequestHelper rh){
    this.rh=rh;
}
public RequestHelper getRequestHelper(){
    return this.rh;
}}

现在我想测试调用RequestHelper来填充orderType对象的ServiceClient类。如何存根RequestHelper类的方法。

Answer 1

在这种情况下，如果不对rh文件进行验证，您只需要一个普通的Stub -只是为了确保在测试docall方法时不会抛出NullPointerException。Mock也足够了，但是它是更高级的对象，在这里使用它是没有意义的。当涉及到Spy时，它用于验证对真实对象的调用(就不被模拟而言)。看看下面的例子--只需使用Stub就可以顺利运行

@Grab('org.spockframework:spock-core:1.0-groovy-2.4')
@Grab('cglib:cglib-nodep:3.1')

import spock.lang.*

class Test extends Specification {
    def 'spec'() {
        given:
        def service = new ServiceClient()    
        service.rh = Mock(RequestHelper)

        when:
        service.doCall(new Order())

        then:
        noExceptionThrown()
    }
}

class Order {
    String product
    String quantity
    String profile
}

class OrderType { }

class FACTORY {
    static OrderType CreateOrderType = new OrderType()
}

class RequestHelper {
    public void populateOrderRequestBody(String product, String quantity, String profile, OrderType orderType) {
        orderType.setProduct(product);
        orderType.setQuantity(Integer.parseInt(quantity));
        orderType.setUser(profile.getUserId());
    } 
}

class ServiceClient {
   RequestHelper rh;

   public void doCall(Order order) {
      OrderType  orderType = FACTORY.CreateOrderType;
      rh.populateOrderRequestBody(order.getProduct(), order.getQuantity(), order.getProfile(), orderType);
   }

    public setRequestHelper(RequestHelper rh){
        this.rh=rh;
    }
    public RequestHelper getRequestHelper(){
        return this.rh;
    }
}

Answer 2

与Opal的答案非常相似，但使用的是模拟订单。

class Test extends Specification {
def 'spec'() {
    given:
    def service = new ServiceClient()
    def order = Mock(Order)
    order.getProduct() >> 'product1'
    order.getProfile() >> 'profile1'
    order.getQuantity() >> 3


    service.rh = Mock(RequestHelper)

    when:
    service.doCall(order)

    then:
    noExceptionThrown()
    1 * rh.populateOrderRequestBody('product1',3,'profile1',FACTORY.CreateOrderType)
}
}

请注意，只有当CreateOrderType.equals()返回true时，这才有效
