Mockito Junit 5抛出检查异常不起作用
Mockito Junit 5抛出检查异常不起作用
提问于 2020-10-25 08:40:25
我试图在方法调用期间抛出SQLException。但是由于某种原因，异常不会被抛出。
错误消息
org.opentest4j.AssertionFailedError: Expected java.sql.SQLException to be thrown, but nothing was thrown.
at org.junit.jupiter.api.AssertThrows.assertThrows(AssertThrows.java:71)
at org.junit.jupiter.api.AssertThrows.assertThrows(AssertThrows.java:37)
at org.junit.jupiter.api.Assertions.assertThrows(Assertions.java:2952)我希望在调用dropRun()时抛出异常
public interface RunRepository {
void dropRun(List<Integer> ids) throws SQLException;
}它的实现
public class RunRepositoryImpl implements RunRepository{
@Override
public void dropRun(List<Integer> ids) throws SQLException {
//some piece of code
}
}我想测试的类
public interface Project {
void purge() throws SQLException;
}和它的实现
public ProjectImpl implements Project{
@Override
public void purge() throws SQLException {
//some piece of code
try {
runRepository.dropRun(ids);
} catch (Exception e) {
LOGGER.error("Error purging completed runs.");
throw e;
}
}
}测试类

import static org.mockito.ArgumentMatchers.any;
import static org.mockito.BDDMockito.willAnswer;

@TestInstance(Lifecycle.PER_CLASS)
@ExtendWith(MockitoExtension.class)
public class ProjectImplTest {
private Project project;
@Mock
private RunRepository runRepository;
@BeforeEach
public void setUp() {
//some piece of code
project = new ProjectImpl(runRepository);
}
@Test
public void GIVEN_non_empty_completed_runs_WHEN_purge_is_invoked_THEN_dropRun_is_invoked()
throws SQLException {
//MOCK Trail 1 DIDN'T WORK
//doThrow(SQLException.class).when(runRepository).dropRun(any());
//MOCK Trail 2 DIDN'T WORK either
willAnswer(invocation -> {
throw new SQLException();
}).given(runRepository).dropRun(any());
//Then
assertThrows(SQLException.class, () -> project.purge());
}
}我尝试了几个链接，但没有成功！任何帮助都将不胜感激。蒂娅。

我也面临着同样的问题，下面的代码不起作用。JUnit失败，错误为
org.mockito.exceptions.base.MockitoException:
Checked exception is invalid for this method!
Invalid: javax.xml.bind.JAXBException: aaDocumentService documentService = mock(DocumentService.class);
@Test
@DisplayName("Returns 500 http status when we have an error calling the PFEL")
void handle_document_create_request_exception_in_service() {
willThrow(new JAXBException("aa")).given(documentService).generateDocument(any(DocumentCreateDto.class));
}但是如果我用RunTime异常替换CheckedExcpetion，它会像预期的那样工作
