单元测试

依赖

3.8.0版本已支持mock静态类的静态方法. 但是使用上需要注意

<!-- https://mvnrepository.com/artifact/org.mockito/mockito-core -->
<dependency>
    <groupId>org.mockito</groupId>
    <artifactId>mockito-core</artifactId>
    <version>3.8.0</version>
    <scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.mockito/mockito-inline -->
<dependency>
    <groupId>org.mockito</groupId>
    <artifactId>mockito-inline</artifactId>
    <version>3.8.0</version>
    <scope>test</scope>
</dependency>

静态方法

public class XxxTest {
    static MockedStatic<LoginUtils> loginUtilsMockedStatic;
    @BeforeClass
    public static void beforeClass() throws Exception {
        loginUtilsMockedStatic = mockStatic(LoginUtils.class);
        loginUtilsMockedStatic.when(LoginUtils::getCompanyId).thenReturn(0L);
        loginUtilsMockedStatic.when(LoginUtils::getUid).thenReturn(2);
        loginUtilsMockedStatic.when(LoginUtils::getCompanyIdAndUid).thenReturn(Tuple2.of(1L, 2L));
    }
    @AfterClass
    public static void afterClass() throws Exception {
        loginUtilsMockedStatic.close();
    }
}

其他问题

• dao相关需要验证sql正常，避免线上出现sql执行错误的问题。

• 待测试内部private方法不mock，如果要mock，可以调整为protected

  • mock 父类方法

  • mock 当前类某些方法

    public class WaitTestClassTest {
    @Mock // mock外部方法的调用
    Example1 example1;
    @Mock 
    Example2 example2;
    @Spy // 自己的方法， 父类的方法
    @InjectMocks //待验证的class
    WaitTestClass waitTestClass;
    @Test
    public vod testCreate(){
       doReturn(true).when(waitTestClass).saveBatch(anyList());
       assertTrue(waitTestClass.saveBatch(anyList()));
       when(example1.getGlobalId()).thenReturn(System.currentTimeMillis());
       when(example2.countRelationsByTagId(anyLong(), anyLong())).thenReturn(0);
       final SingleEditDto singleEditDto = new SingleEditDto();
       //setter...
       waitTestClass.singleEdit(singleEditDto);
    }
    }
