Use in-memory db to record tests for Rest controllers

I am writing a test for the Spring boot controller. This remainder controller writes some values ​​to db.

I want to use the in-memory database that Spring provides this test. According to this document , I should annotate a test class @DataJpaTestthat causes this error:

java.lang.IllegalStateException: Failed to load ApplicationContext

Further in the error stack trace, I see the following exception:

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource': Invocation of init method failed; nested exception is java.lang.IllegalStateException: Failed to replace DataSource with an embedded database for tests. If you want an embedded database please put a supported one on the classpath or tune the replace attribute of @AutoconfigureTestDatabase.

This is the testing class I'm working on:

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
@DataJpaTest
public class AuthenticationControllerFTest {

    @Autowired 
    private MockMvc mockMvc;

    @MockBean
    private AuthenticationManager authenticationManager;

    @Autowired
    private WebApplicationContext context;

    @Autowired
    private Filter springSecurityFilterChain;

    @Before
    public void setup() {
        mockMvc = MockMvcBuilders.webAppContextSetup(context)
                .addFilters(springSecurityFilterChain).build();
    }

    @Test
    public void testCreate() throws Exception {

        String exampleUserInfo = "{\"name\":\"Salam12333\",\"username\":\"test@test1.com\",\"password\":\"Salam12345\"}";
        RequestBuilder requestBuilder = MockMvcRequestBuilders
                .post("/signup")
                .accept(MediaType.APPLICATION_JSON).content(exampleUserInfo)
                .contentType(MediaType.APPLICATION_JSON);

        MvcResult result = mockMvc.perform(requestBuilder).andReturn();

        MockHttpServletResponse response = result.getResponse();
        int status = response.getStatus();
        Assert.assertEquals("http response status is wrong", 200, status);
    }
}

What causes this error?

Edit 1 This is my content application.properties:

spring.datasource.username = hello
spring.datasource.password = hello
spring.datasource.driver-class-name= com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/myproject?useSSL=false

server.port = 8443
server.ssl.key-store = classpath:tomcat.keystore
server.ssl.key-store-password = hello
server.ssl.key-password = hello
server.ssl.enabled = true
server.ssl.key-alias=myproject

Edit 2

I added the following to pom.xml:

<dependency>
    <groupId>org.hsqldb</groupId>
    <artifactId>hsqldb</artifactId>
    <scope>test</scope>
</dependency>

I created application-test.propertieswith the following contents:

spring.datasource.username= root
spring.datasource.password= password
spring.datasource.driver-class-name= org.h2.Driver
spring.datasource.url= jdbc:h2:mem:db;DB_CLOSE_DELAY=-1
  • What is a username and password? Where should I install them?
  • @ActiveProfiles("test") , , , :
