Not able to save data in H2 Database using SpringBootTest and Spring JPA Repository - spring

Question

I am using #SpringBootTest to test SpringSecurity basic authentication.When I test it,the h2 database does not save the data.I do not see the insert statement in the console,which I apparently see when I am running my actual SpringBoot Application and inserting the data from frontend. Please help.
Below is my test:
#SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT)
#ContextConfiguration(classes=ConnectionsAppApplication.class)
#Transactional
public class AuthenticationTest {
#Autowired
private WebApplicationContext context;
private MockMvc mockMvc;
#Mock
CustDetailsRepository custRepository;
#Mock
BCryptPasswordEncoder encrypt;
#InjectMocks
CustomerServiceImpl customerServiceImpl;
#BeforeEach
public void setup() {
MockitoAnnotations.initMocks(this);
mockMvc = MockMvcBuilders
.webAppContextSetup(context)
.apply(springSecurity())
.build();
}
#Test
void testAuthentication() {
CustomerDetails customer = new CustomerDetails();
customer.setEmailid("abc.com");
customer.setPassword("abc#123456");
customerServiceImpl.saveUser(customer);
try {
this.mockMvc.perform(get("/api/login")
.with(httpBasic("abc.com","abc#123456")))
.andDo(print())
.andExpect(status().isOk())
.andReturn();
} catch (Exception e) {
e.printStackTrace();
}
}
}
saveUser method in CustomerServiceImpl class:
public void saveUser(CustomerDetails customerDetails) {
customerDetails.setPassword(bCryptPasswordEncoder.encode(customerDetails.getPassword()));
custDetailsRepository.save(customerDetails);
}

You have 2 options to implement this test:
Option 1: use real h2
#SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT)
#ContextConfiguration(classes=ConnectionsAppApplication.class)
#Transactional
public class AuthenticationTest {
#Autowired
private WebApplicationContext context;
private MockMvc mockMvc;
#Autowired
CustomerServiceImpl customerServiceImpl;
#BeforeEach
public void setup() {
mockMvc = MockMvcBuilders
.webAppContextSetup(context)
.apply(springSecurity())
.build();
}
#Test
void testAuthentication() {
CustomerDetails customer = new CustomerDetails();
customer.setEmailid("abc.com");
customer.setPassword("abc#123456");
customerServiceImpl.saveUser(customer);
try {
this.mockMvc.perform(get("/api/login")
.with(httpBasic("abc.com","abc#123456")))
.andDo(print())
.andExpect(status().isOk())
.andReturn();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Option 2: Mock your service / repository
#SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT)
#ContextConfiguration(classes=ConnectionsAppApplication.class)
#Transactional
public class AuthenticationTest {
#Autowired
private WebApplicationContext context;
private MockMvc mockMvc;
#MockBean
CustomerServiceImpl customerServiceImpl;
#BeforeEach
public void setup() {
mockMvc = MockMvcBuilders
.webAppContextSetup(context)
.apply(springSecurity())
.build();
}
#Test
void testAuthentication() {
// set expectations on CustomerServiceImpl
CustomerDetails customer = new CustomerDetails();
customer.setEmailid("abc.com");
customer.setPassword("abc#123456");
// mock the method you use to fetch the customer
when(customerServiceImpl.getUser("abc.com").thenReturn(customer);
try {
this.mockMvc.perform(get("/api/login")
.with(httpBasic("abc.com","abc#123456")))
.andDo(print())
.andExpect(status().isOk())
.andReturn();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Note that you also can use #WebMvcTest to test only the web slice of your app (meaning no other beans will be instantiated, for example all sercies you depend in the controller must be delivered by #MockBean)
