使用 PowerMockito 在 JUnit5 中模拟静态方法

需要帮助使用JUnit5和PowerMockito框架模拟静态方法。

Powermock junit5 和 mockito2.x 无法正常工作 RunnerTestSuiteChunker 未找到

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

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

但是面对一个问题,我知道 Junit5 有一个现有的问题,但任何人都知道任何其他方法来模拟使用 JUnit5 使用 powermock 的静态方法。


答案 1

使用mockito v 3.4.0,我们可以简单地使用mokenStatic()方法,而无需powermock库:

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

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

答案 2

您正在使用@Before这是 junit4 注释。Junit5 具有@BeforeEach/@BeforeAll(以符合您的要求为准)。此外,您导入的@Test来自 junit4,而不是来自 junit5(这应该是 org.junit.jupiter.api.Test;)
