    private static Logger logger = LogManager.getLogger(LoggingsInfo.class);

    public static void main(String args[]) {
        System.out.println("Execution started: ");
    }
}

Step 4 : Configurations in log4j2.properties file.

name=PropertiesConfig
property.filename = logs
appenders = console, file

appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%–5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n

appender.file.type = File
appender.file.name = LOGFILE
appender.file.fileName=${filename}/LogsGenerated.log
appender.file.layout.type=PatternLayout
appender.file.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n

loggers=file
logger.file.name=Logs
logger.file.level=debug
logger.file.appenderRefs = file
logger.file.appenderRef.file.ref = LOGFILE

rootLogger.level = debug
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT

Along with that a file LogsGenerated.log get generated within the log folder within the project containing the logging information as the console output.

Run mvn clean install to download and set up all dependencies.

Step 3: Organize Your Project Structure

Create the following basic folder structure:

src
├── main
│   └── java
│       └── com.example.demo (your main app code)
├── test
│   └── java
│       └── com.example.demo (your test code)

Step 4: Create Sample Test Classes

@SpringBootTest
public class SampleUnitTest {

    @Test
    void sampleTest() {
        Assertions.assertTrue(true);
    }
}

1. API Automation Testing with Spring Boot

Goal: Automate API testing like GET, POST, PUT, DELETE requests.

In Spring Boot, TestRestTemplate is commonly used for API calls in tests.

Example: Test GET API for fetching user details

User API Endpoint:

GET /users/1

Sample Response:

{
  "id": 1,
  "name": "John Doe",
  "email": "[email protected]"
}

Test Class with Code:

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class UserApiTest {

    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    void testGetUserById() {
        ResponseEntity<User> response = restTemplate.getForEntity("/users/1", User.class);

        assertEquals(HttpStatus.OK, response.getStatusCode());
        assertEquals("John Doe", response.getBody().getName());
    }
}

2. Test Data Setup using Spring Data JPA

In automation, managing test data is crucial. Spring Boot allows you to set up data directly in the database before running your tests.

Example: Insert User Data Before Test Runs

@SpringBootTest
class UserDataSetupTest {

    @Autowired
    private UserRepository userRepository;

    @BeforeEach
    void insertTestData() {
        userRepository.save(new User("John Doe", "[email protected]"));
    }

    @Test
    void testUserExists() {
        List<User> users = userRepository.findAll();
        assertFalse(users.isEmpty());
    }
}

Explanation:

• @BeforeEach → Runs before every test.
• userRepository.save() → Inserts data into DB.
• No need for SQL scripts — use Java objects directly!

3. Mocking External APIs using MockMvc

MockMvc is a powerful tool in Spring Boot to test controllers without starting the full server.

Example: Mock POST API for Creating User

@SpringBootTest
@AutoConfigureMockMvc
class UserControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    void testCreateUser() throws Exception {
        mockMvc.perform(post("/users")
                .content("{\"name\": \"John\", \"email\": \"[email protected]\"}")
                .contentType(MediaType.APPLICATION_JSON))
                .andExpect(status().isCreated());
    }
}

Explanation:

4. End-to-End Integration Testing (API + DB)

Example: Validate API Response + DB Update

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class UserIntegrationTest {

    @Autowired
    private TestRestTemplate restTemplate;

    @Autowired
    private UserRepository userRepository;

    @Test
    void testAddUserAndValidateDB() {
        User newUser = new User("Alex", "[email protected]");

        ResponseEntity<User> response = restTemplate.postForEntity("/users", newUser, User.class);

        assertEquals(HttpStatus.CREATED, response.getStatusCode());

        List<User> users = userRepository.findAll();
        assertTrue(users.stream().anyMatch(u -> u.getName().equals("Alex")));
    }
}

Explanation:

• Calls POST API to add user.
• Validates response code.
• Checks in DB if user actually inserted.

5. Mock External Services using WireMock

Useful for simulating 3rd party API responses.

@SpringBootTest
@AutoConfigureWireMock(port = 8089)
class ExternalApiMockTest {

    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    void testExternalApiMocking() {
        stubFor(get(urlEqualTo("/external-api"))
                .willReturn(aResponse().withStatus(200).withBody("Success")));

        ResponseEntity<String> response = restTemplate.getForEntity("http://localhost:8089/external-api", String.class);

        assertEquals("Success", response.getBody());
    }
}

Best Practices for Testers using Spring Boot

• Follow clean code practices.
• Use Profiles for different environments (dev, test, prod).
• Keep test configuration separate.
• Reuse components via dependency injection.
• Use Mocking wherever possible.
• Add proper logging for better debugging.
• Integrate with CI/CD for automated test execution

Conclusion

Spring Boot is no longer limited to backend development — it has emerged as a powerful tool for testers, especially for API automation, backend testing, and test data management. Testers who learn to leverage Spring Boot can build scalable, maintainable, and robust automation frameworks with ease. By combining Spring Boot with other testing tools and frameworks, testers can elevate their automation skills beyond UI testing and become full-fledged automation experts. At Codoid, we’ve adopted Spring Boot in our testing toolkit to streamline API automation and improve efficiency across projects.
