[英]Junit Force to throw Exception on method call
I am trying to throw the exception whenever simpleJdbcCall.execute(namedParameters)
called but I see it is not throwing the error, is there something i am missing here?每当调用
simpleJdbcCall.execute(namedParameters)
时,我都会尝试抛出异常,但我看到它没有抛出错误,这里有什么我遗漏的吗?
Here is my class这是我的 class
class A {
@Autowired
JdbcTemplate jdbcTemplate;
@Autowired
private SimpleJdbcCall simpleJdbcCall;
public int mymeth(){
simpleJdbcCall.withProcedureName("myproc").declareParameters(new SqlParameter("ID",
Types.VARCHAR);
SqlParameterSource namedParameters = new MapSqlParameterSource("id" , 12);
Map<String, Object> result = null;
try {
//I want Junit to throw error here
result = simpleJdbcCall.execute(namedParameters);
} catch (Exception e) {
throw new Exception(e.getMessage());
}
return (Integer) result.get("Status");
}
}
here is my Junit Class这是我的 Junit Class
@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
Class ATest{
@Autowired
private A obj;
@Test
public void throwExceptionFromMethod() {
try {
SimpleJdbcCall simpleJdbcCall = Mockito.mock(SimpleJdbcCall.class);
SqlParameterSource sqlParameterSource = Mockito.mock(SqlParameterSource.class);
Mockito.doThrow(new RuntimeException()).when(simpleJdbcCall ).execute((Object)
Mockito.any());
final int message = obj.mymeth(modifyLeadDispositionRequest);
Assert.assertEquals(0, message);
} catch (Exception e) {
e.printStackTrace();
}
}
}
When writing spring-boot integration test you should inject the mock beans using @MockBean annotation在编写 spring-boot 集成测试时,您应该使用@MockBean注释注入模拟 bean
@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
Class ATest {
@Autowired
private A obj;
@MockBean
private SimpleJdbcCall simpleJdbcCall;
@Test
public void throwExceptionFromMethod() {
try {
Mockito.when(simpleJdbcCall.withProcedureName(Mockito.anyString())).thenReturn(simpleJdbcCall);
Mockito.when(simpleJdbcCall.declareParameters(Mockito.any())).thenReturn(simpleJdbcCall);
Mockito.doThrow(new RuntimeException()).when(simpleJdbcCall).execute(
ArgumentMatchers.any(SqlParameterSource.class));
//or you can use thenThrow also
Mockito.when(simpleJdbcCall.execute(ArgumentMatchers.any(SqlParameterSource.class))).thenThrow(RuntimeException.class);
final int message = obj.mymeth(modifyLeadDispositionRequest);
} catch (Exception e) {
e.printStackTrace();
// just to assert here
}
}
}
You can a follow some of the examples here for testing exceptions in junit4 or junit5您可以按照此处的一些示例来测试junit4或junit5中的异常
