Spring Boot对服务进行单元测试，手动测试通过但模拟服务失败

Question

为了测试我的服务逻辑，我必须在 3 个存储库中设置一些初始测试数据。测试的那部分工作正常，但是服务应该进行的更新永远不会在存储库中发生，并且测试失败。希望如果我显示测试后跟服务逻辑，它会更清楚我要做什么。

我想我可能遗漏了一些与正确模拟服务有关的注释。我认为模拟服务未连接到其模拟存储库。我不知道要添加哪些特定配置。

代码如下：

测试：

package portal.services;

import static org.junit.Assert.assertEquals;

@RunWith(SpringJUnit4ClassRunner.class)
@DataJpaTest
public class TestRunServiceTest {
    @MockBean
    private TestRunService testRunService;
    @Autowired
    private TestRunRepository testRunRepository;
    @Autowired
    private TestCaseRepository testCaseRepository;
    @Autowired
    private TestToolRepository testToolRepository;
    @Autowired
    private TestSuiteRepository testSuiteRepository;

    TestCase testCase = new TestCase();
    TestTool testTool = new TestTool();
    TestSuite testSuite = new TestSuite();
    TestRun testRun = new TestRun();

    @Before 
    public void createTestData(){
        // create the test case
        testCase.setId(1);
        testCase.setName("Agent Charities");
        testCaseRepository.save(testCase);

        // create test tool
        testTool.setId(1);
        testToolRepository.save(testTool);

        //create test suite
        testSuite.setId(1);
        testSuite.setTestCase(testCase);
        testSuite.setTestTool(testTool);
        testSuiteRepository.save(testSuite);

        // create test run
        testRun.setTestSuite(testSuite);
        testRun.setStartDateTime(new Date());
        testRun.setEndDateTime(new Date());
    }

    @Test
    public void aggregateDataCountWhenResultIsPass(){

        // test run result is true with 5 data items
        testRun.setResult(true);
        testRun.setGeneratedDataCount((long)5);
        testRunService.add(testRun);

        // test run result is false with 3 data items
        testRun.setResult(false);
        testRun.setGeneratedDataCount((long)3);
        testRunService.add(testRun);

        // TEST FAILS BECAUSE testRunService did not persist any data
        System.out.println(testRunRepository.count()); //output = 0

        // test tool and test case repositories should show count of 5
        assertEquals((long)5, testCaseRepository.findByid((long)1).getGeneratedDataCount().longValue());
        assertEquals((long)5, testToolRepository.findByid((long)1).getGeneratedDataCount().longValue());
        // test failed with NullPointerException, GeneratedDataCount was not updated by testRunService
    }

}

服务：

public interface TestRunService {
    Iterable<TestRun> listAllTestRuns();
    TestRun getTestRunById(Integer id);
    ResponseEntity<?> add(@RequestBody TestRun input);
}


@Service
public class TestRunServiceImpl implements TestRunService {

    private TestRunRepository testRunRepository;
    private TestSuiteRepository testSuiteRepository;
    private TestCaseRepository testCaseRepository;
    private TestToolRepository testToolRepository;

    @Autowired
    public void setTestRunRepository(TestRunRepository testRunRepository) {
        this.testRunRepository = testRunRepository;
    }
    @Autowired
    public void setTestSuiteRepository(TestSuiteRepository testSuiteRepository) {
        this.testSuiteRepository = testSuiteRepository;
    }
    @Autowired
    public void setTestCaseRepository(TestCaseRepository testCaseRepository) {
        this.testCaseRepository = testCaseRepository;
    }
    @Autowired
    public void setTesttOOLRepository(TestToolRepository testToolRepository) {
        this.testToolRepository = testToolRepository;
    }

    @Override
    public Iterable<TestRun> listAllTestRuns() {
        return testRunRepository.findAll();
    }

    @Override
    public TestRun getTestRunById(Integer id) {
        return testRunRepository.findOne((long)id);
    }

    @Override
    public ResponseEntity<?> add(@RequestBody TestRun input) {

        // save te test run
        TestRun result = testRunRepository.save(input);
        URI location = ServletUriComponentsBuilder
                .fromCurrentRequest().path("/{id}")
                .buildAndExpand(result.getId()).toUri();

        // update runtime total for test TOOL
        TestSuite suite = testSuiteRepository.findByid(result.getTestSuite().getId());
        TestTool tool = testToolRepository.findByid(suite.getTestTool().getId());
        tool.setTotalRuntime(result.getRuntimeMilliseconds());

        // if the run was a pass, update the generated data count as well
        if (result.getResult() == true){
            tool.setGeneratedDataCount(result.getGeneratedDataCount());
        }
        // save updated test tool information
        testToolRepository.save(tool);

        // update runtime total for test CASE
        TestCase testCase = testCaseRepository.findByid(suite.getTestCase().getId());
        testCase.setTotalRuntime(result.getRuntimeMilliseconds());

        // if the run was a pass, update the generated data count as well
        if (result.getResult() == true){
            testCase.setGeneratedDataCount(result.getGeneratedDataCount());
        }
        // save updated test case information
        testCaseRepository.save(testCase);

        return ResponseEntity.created(location).build();        
    }
}

问题是我知道该服务是通过手动测试和检查数据库来工作的，所以我无法让单元测试通过，这让我很沮丧。

Answer 1

我不确定您为什么要为您的服务使用 @MockBean 注释。

您可以尝试在您的设置方法中构造一个适当的 TestRunService 对象并使用它吗？

例如：

@Before 
public void createTestData(){
     //set up service
     testRunService = new TestRunServiceImpl();
     //invoke repository setters on your service object
     //data creation     
}

Answer 2

1. 使用SpringRunner.class 代替SpringJUnit4ClassRunner.class，并将@MockBean 更改为@Autowired。 @DataJpaTest 为必填项。

2. 如果有ContextConfiguation、PersistenceConfig等需要的配置需要使用@Import({ContextConfiguation.class,...})导入

3. 使用@TestConfiguration创建模拟bean

   @TestConfiguration 静态类 TestRunServiceImplTextContextConfig { @豆 公共测试运行服务 testRunService() { 返回新的 TestRunServiceImpl(); } }

我使用 Spring Boot 2.1.1 进行了测试。
