Spock单元测试-mock static方法（普通类中的static方法）

我是靠谱客的博主朴素香氛，这篇文章主要介绍Spock单元测试-mock static方法（普通类中的static方法），现在分享给大家，希望可以做个参考。

groovy单元测试，mock静态方法，需要使用PowerMockito。还会影响其他普通方法的mock。
例如下面的代码：
1.OrderInfoServiceProxy.getOrderInfo为静态方法。
2.orderActionServiceProxy.updateOrderData为普通public方法，但是该类有static公共变量。
但是如果用spock+PowerMockito，mock掉上面第一条。第二条也需要在PrepareForTest注解上加上该类

复制代码

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(Sputnik.class)
@PrepareForTest([OrderInfoServiceProxy.class, OrderActionServiceProxy.class])
@SuppressStaticInitializationFor(["com.ctrip.tourtailor.vendorform.service.biz.proxy.OrderInfoServiceProxy", "com.ctrip.tourtailor.vendorform.service.biz.proxy.OrderActionServiceProxy"])
class OrderServiceTimeCoreSpockTest extends Specification {
def orderServiceTimeCore = new OrderServiceTimeCore()
def orderActionServiceProxy = Mock(OrderActionServiceProxy)
void setup() {
//调用该类的普通方法，但是有static公共变量,所以需要在PrepareForTest注解上加上该类
orderServiceTimeCore.orderActionServiceProxy = orderActionServiceProxy
//调用该类的static方法
PowerMockito.mockStatic(OrderInfoServiceProxy.class)
}
def "Update4126ClientConfirmTime"() {
given: "OOrder"
//查询订单
Calendar calendar = Calendar.getInstance()
calendar.add(Calendar.DATE, -1)
//静态方法
PowerMockito.when(OrderInfoServiceProxy.getOrderInfo(1L, true)).thenReturn(new OrderInfoDTO(orderId: 1L, orderDate: calendar))
PowerMockito.when(OrderInfoServiceProxy.getOrderInfo(2L, true)).thenReturn(null)
//普通方法
orderActionServiceProxy.updateOrderData(_, _, _) >> _
expect:
orderServiceTimeCore.update4126ClientConfirmTime(orderId, date);
where:
orderId | date
|| _
1
| new Date() || _
2
| new Date() || _
1
| null
|| _
}

PowerMockito.when(OrderInfoServiceProxy.getOrderInfo(2L, true)).thenReturn(null)
//普通方法
orderActionServiceProxy.updateOrderData(_, _, _) >> _

}

普通方法测试对比。
orderActionServiceProxy.updateOrderData为普通public方法，但是该类有static公共变量。却不用加PrepareForTest注解。
