Question

我正在尝试将JUnit 5集成到Eclipse Oxygen3下。该项目已经有Mockito 2。

我已经完成了https://www.baeldung.com/mockito-junit-5-extension中建议的所有步骤，如下所示：

依赖项：

junit-jupiter-engine 5.5.0
junit-jupiter-api 5.5.0
junit-vintage-engine 5.5.0
junit-platform-runner 1.5.0
mockito-core 2.28.2
mockito-junit-jupiter 2.28.2

代码：

public class Jupiter {

    public boolean isAlpha() {
        return true;
    }

}

测试代码：

import static org.assertj.core.api.Assertions.assertThat;
import static org.mockito.BDDMockito.given; 
import java.util.Date;  
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.junit.platform.runner.JUnitPlatform;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.junit.jupiter.MockitoExtension;

@ExtendWith(MockitoExtension.class)
@RunWith(JUnitPlatform.class)
public class JupiterTest {

    @InjectMocks
    private Jupiter jupiter;

    @BeforeEach
    public void setup() {
        //usually some stuff here
    }

    @Test
    @DisplayName("heading jupiter - make it so")
    public void test() {
        boolean result = jupiter.isAlpha();

        assertThat(result).isTrue();
    }
}

不幸的是，运行测试失败。

有人偶然发现类似的问题吗？是一般问题还是我的项目特定问题？

Answer 1

不确定为什么需要所有老式的和平台的东西。.您的测试是org.junit.jupiter.api.Test;

我会这样做：

1）从班级删除所有注释

2）初始化Mockito：

@BeforeEach
public void setup() {
    MockitoAnnotations.initMocks(this);
}

3）这些部门应该足够了：

junit-jupiter 5.5.0
mockito-core 2.28.2

Answer 2

mockito-junit-jupiter 2.28.2允许您使用这种方式，这可能可以解决您的问题。

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.mockito.InjectMocks;
import org.mockito.junit.jupiter.MockitoSettings;

import static org.assertj.core.api.Assertions.assertThat;
import static org.mockito.quality.Strictness.LENIENT;

@MockitoSettings(strictness = LENIENT)
public class JupiterTest {

   @InjectMocks
   private Jupiter jupiter;

   @BeforeEach
   public void setup() {
      //usually some stuff here
   }

   @Test
   @DisplayName("heading jupiter - make it so")
   public void test() {
      boolean result = jupiter.isAlpha();

      assertThat(result).isTrue();
   }
}

Mockito 2 + Junit 5 NoSuchMethodError在AnnotationSupport.findAnnotation上
