Mockito呼び出し静的メソッドとvoidメソッド

 
  
1 mock 静态方法
 
  
mockito库并不能mock静态方法，需要依赖powermock
 
  
第一步：给类添加注解
 
  
//        ，        powermock       mock
  
@ContextConfiguration
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@PrepareForTest(     .class)
  
public 
class SupplierServiceImplTest extends PowerMockTestCase {} 
ステップ2:mock使用
@Test(expectedExceptions = BusinessException.class)
public void testAddSupplierAccount_genIdentityNoError() {
    //   powermock，  mock         
	PowerMockito.mockStatic(PasswordGenerator.class);

	final SupplierAccountDto supplierAccountDto = new SupplierAccountDto();
	supplierAccountDto.setName("  ");
	final String randomPWd = "666";

	PowerMockito.when(supplierDao.selectByEmail(anyString()))
			.thenReturn(new ArrayList());
	//     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);
}
  
2 mock voidメソッド
// void ，doNothing    
PowerMockito.doNothing().when(casService).addSupplier(anyLong(), any(ServiceKey.class));
