spock+PowerMock静态方法

野性酷女 2022-03-10 12:10 302阅读 0赞

## 示例 ##

package arthur.dy.lee.mybatisplusdemo.reflect;
    
    /** * @auther arthur.dy.lee * @since 2019/3/10 23:08 */
    class Account { 
    
        public static String getType() { 
            return "Personal";
        }
    }
    
    public class Customer { 
        public String getAccountType() { 
            return Account.getType();
        }
    }

## 注意 ##

spock有GroovyMock类，它可以mock静态方法，但它对于groovy文件类很好，对于Java类，不能全局工作。

> Java静态方法的问题在于，当使用Groovy进行测试时，它们是从Java类调用的，而这些调用类正是您要测试的类。  
> 例如，如果我们现在有一个Customer Java类和一个Account Java类，以及一个CustomerTest Groovy类，那么ExpandoMetaClass和GroovyMock方法将不能全局工作，而只能在本地工作。

## 使用 ##

package arthur.dy.lee.mybatisplusdemo.reflect
    
    import org.junit.runner.RunWith
    import org.powermock.api.mockito.PowerMockito
    import org.powermock.core.classloader.annotations.PrepareForTest
    import org.powermock.modules.junit4.PowerMockRunner
    import org.powermock.modules.junit4.PowerMockRunnerDelegate
    import org.spockframework.runtime.Sputnik
    import spock.lang.Specification
    
    @RunWith(PowerMockRunner.class)
    @PowerMockRunnerDelegate(Sputnik.class)
    @PrepareForTest([Account])
    class CustomerTest extends Specification { 
    
        def "GetAccountType"() { 
            setup:
            PowerMockito.mockStatic(Account.class);
            PowerMockito.when(Account.getType()).thenReturn("bb")
            Customer cust = new Customer();
    
            when:
            String ret = cust.getAccountType()
    
            then:
            ret == "bb"
        }
    }
