使用PowerMockito模拟JUnit5中的静态方法 [英] Mock Static Methods in JUnit5 using PowerMockito

问题描述

需要在PowerMockito框架中使用JUnit5模拟静态方法的帮助.

Need help for Mocking Static methods using JUnit5 with PowerMockito framework.

​​ Powermock junit5和mockito2.x无法正常运行RunnerTestSuiteChunker找不到

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PowerMockIgnore;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

import static org.mockito.Mockito.*;


@PrepareForTest(EnvironmentUtils.class)
@RunWith(PowerMockRunner.class)
public class RuleControllerTest {       

        @Before
        public void setup() {           
            PowerMockito.mockStatic(EnvironmentUtils.class);
        }   


        @Test
        public void test_rule_create_rule() throws IOException {
            when(EnvironmentUtils.isCF()).thenReturn(true);

        }
}

和pom.xml

我从这里关注了Junit5示例， 1) https://www.baeldung.com/junit-5 2) Junit5模拟静态方法

I followed Junit5 sample from here, 1) https://www.baeldung.com/junit-5 2) Junit5 mock a static method

但是面对一个问题，我知道Junit5有一个现有的 issue 使用powermock，但是任何人都知道使用powermock使用JUnit5模拟静态方法的任何其他方式.

But facing an issue as, I know there is an existing issue for Junit5 with powermock but any one knows any other way to Mock static methods using JUnit5 using powermock.

推荐答案

使用Mockito v 3.4.0，我们可以简单地使用 mockStatic()方法，而无需使用powermock库:

With mockito v 3.4.0 we can simply use mockStatic() method without powermock library :

 try (MockedStatic mocked = mockStatic(Foo.class)) {
   mocked.when(Foo::method).thenReturn("bar");
   assertEquals("bar", Foo.method());
   mocked.verify(Foo::method);
 }

assertEquals("foo", Foo.method());
