如何在Spring Boot中使用FongoFake mongo进行集成测试

如何解决如何在Spring Boot中使用FongoFake mongo进行集成测试

我正在使用mongodb作为后端的Spring Boot应用程序。

用于操作的mongorepository

我想使用假mongo（fongo）进行集成测试

我已从以下链接中获取参考，以便使用fongo进行集成测试，但是没有运气。

https://www.paradigmadigital.com/dev/tests-integrados-spring-boot-fongo/

集成测试正在尝试连接到真实数据库并且IT失败

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = { ConfigServerWithFongoConfiguration.class },properties = {
        "server.port=8980" },webEnvironment = WebEnvironment.DEFINED_PORT)
@AutoConfigureMockMvc
@TestPropertySource(properties = { "spring.data.mongodb.database=test" })
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD)
public class PersonControllerITest {

    @Autowired
    private MongoTemplate mongoTemplate;

    @Autowired
    private MockMvc mockMvc;

    private ObjectMapper jsonMapper;

    @Before
    public void setUp() {
        jsonMapper = new ObjectMapper();
    }

    @Test
    public void testGetPerson() throws Exception {

        Person personFongo = new Person();
        personFongo.setId(1);
        personFongo.setName("Name1");
        personFongo.setAddress("Address1");
        mongoTemplate.createCollection("person");
        mongoTemplate.insert(personFongo);

        ResultActions resultAction = mockMvc.perform(MockMvcRequestBuilders.get("http://localhost:8090/api/person/1"));
        resultAction.andExpect(MockMvcResultMatchers.status().is2xxSuccessful());
        MvcResult result = resultAction.andReturn();
        Person personResponse = jsonMapper.readValue(result.getResponse().getContentAsString(),Person.class);
        Assert.assertEquals(1,personResponse.getId());
        Assert.assertEquals("Name1",personResponse.getName());
        Assert.assertEquals("Address1",personResponse.getAddress());

    }

    @Test
    public void testCreatePerson() throws Exception {

        Person personRequest = new Person();
        personRequest.setId(1);
        personRequest.setName("Name1");
        personRequest.setAddress("Address1");

        String body = jsonMapper.writeValueAsString(personRequest);

        ResultActions resultAction = mockMvc.perform(MockMvcRequestBuilders.post("http://localhost:8090/api/person")
                .contentType(MediaType.APPLICATION_JSON).content(body));
        resultAction.andExpect(MockMvcResultMatchers.status().isCreated());

        Person personFongo = mongoTemplate.findOne(new Query(Criteria.where("id").is(1)),Person.class);
        Assert.assertEquals(personFongo.getName(),"Name1");
        Assert.assertEquals(personFongo.getAddress(),"Address1");
    }
}

执行集成测试时出现以下错误

请问您可以提出什么解决方案？

解决方法

我已经尝试过使用您的集成测试和相同配置文件的代码。

但是对于 AbstractFongoBaseConfiguration.class ，我提供了以下代码。

我已删除了该 @EnableAutoConfiguration(exclude={MongoAutoConfiguration.class,MongoDataAutoConfiguration.class}) 行。对我来说很好。

package com.company.myapp;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
import org.springframework.data.mongodb.config.AbstractMongoConfiguration;

import com.github.fakemongo.Fongo;
import com.mongodb.Mongo;
//this exclude i had removed
public abstract class AbstractFongoBaseConfiguration extends AbstractMongoConfiguration{

    @Autowired
    private Environment env;

    @Override
    protected String getDatabaseName() {
        return env.getRequiredProperty("spring.data.mongodb.database");
    }

    @Override
    public Mongo mongo() throws Exception {
        return new Fongo(getDatabaseName()).getMongo();
    }
}

Here我已经用相同的代码附加了视频。

还有一点我想通知您，使您的 ConfigServerWithFongoConfiguration 和 AbstractFongoBaseConfiguration 都与 PersonControllerITest 类。

我还预先假设您的应用程序可以正常运行，而您仅遇到集成测试问题。

这里我还附加了成功运行测试用例的屏幕。

Fongo似乎不再被维护。如果可行，我会切换到“测试容器” https://www.testcontainers.org/modules/databases/mongodb/

这是您尝试做的更好的参考：https://www.baeldung.com/spring-boot-embedded-mongodb

您需要在测试中添加@AutoConfigureDataMongo。

在您的堆栈跟踪中，异常发生在“ MongoConfig”类中。如此处所示：

com.company.myapp.configs.MongoConfig.mongoClient（MongoConfig.java:78）

这向我表明您的Spring配置链未按您的预期进行设置。似乎仍在加载要在实际应用程序环境中使用的实际MongoConfig类。

没有完整的项目（或实际上导致NullPointer的Config类），几乎不可能给出问题的详细答案。但是，我建议您创建一个特定的TestConfig弹簧配置类，以便仅包含要成为测试上下文一部分的主要配置类。

TLDR：：查看您的配置设置，并弄清楚为什么加载MongoConfig.java。如果打算将其加载，请在此处包括它，以便人们找出问题所在。
