mockito测试

在企业开发里面，用mock来做测试。可以避免一些依赖的问题。

大概的形式如下

 

@Before
public void setUp() {
    super.setUp();

    instance = PowerMockito.spy(sysOrgServiceImpl);

    try {
        PowerMockito.doReturn(sysOrgMapper)
                .when(instance, "getBaseMapper");
        MemberModifier.field(SysOrgServiceImpl.class, "baseMapper")
                .set(instance, sysOrgMapper);
        PowerMockito.doReturn(true)
                .when(instance, "remove", any(QueryWrapper.class));
    } catch (Exception e) {
        e.printStackTrace();
    }
}

@Test
public void selectByOrgName() {

    when(sysOrgMapper.selectByOrgName(any(String.class), any(Integer.class)))
            .thenReturn(1);

    assertThat(instance.selectByOrgName("dev", 1)
            , instanceOf(Integer.class));


}
