如何使用Mockito调用静态方法和void方法

// 静态类优先加载，所以需要提前告诉powermock哪些静态类需要mock
@ContextConfiguration
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(springJUnit4ClassRunner.class)
@PrepareForTest(静态调用类.class)
public class SupplierServiceImplTest extends PowerMockTestCase {}

@Test(expectedExceptions = BusinessException.class)
public void testAddSupplierAccount_genIdentityNoError() {
    // 告诉powermock，需要mock该类的所有静态方法
 PowerMockito.mockStatic(PassWordGenerator.class);
 
 final SupplierAccountDto supplierAccountDto = new SupplierAccountDto();
 supplierAccountDto.setName("小明");
 final String randomPWd = "666"; 
 PowerMockito.when(supplierDao.selectByEmail(anyString()))
   .thenReturn(new ArrayList<HaitaoSupplier>());
 // 静态方法mock
 PowerMockito.when(PasswordGenerator.genPwd()).thenReturn(randomPWd);
 PowerMockito.when(pwEncoder.encode(anyString())).thenReturn(randomPWd);
 PowerMockito.when(identityNoGenerator.genIdentityNo()).thenReturn(-1L);
 
 supplierServiceImpl.addSupplierAccount(supplierAccountDto); 
 verify(pwEncoder).encode(randomPWd);
}

// void嘛，doNothing顾名思义
PowerMockito.doNothing().when(casService).addSupplier(anyLong(), any(ServiceKey.class));
