Mocking is an essential part of unit testing, and the Mockito library makes it easy to write clean and intuitive unit tests for your Java code.
Get started with mocking and improve your application tests using our Mockito guide:
Handling concurrency in an application can be a tricky process with many potential pitfalls. A solid grasp of the fundamentals will go a long way to help minimize these issues.

Spring 5 added support for reactive programming with the Spring WebFlux module, which has been improved upon ever since. Get started with the Reactor project basics and reactive programming in Spring Boot:
Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use.
But these can also be overused and fall into some common pitfalls.
To get a better understanding on how Streams work and how to combine them with other language features, check out our guide to Java Streams:

Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.
I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

End-to-end testing is a very useful method to make sure that your application works as intended. This highlights issues in the overall functionality of the software, that the unit and integration test stages may miss.
Playwright is an easy-to-use, but powerful tool that automates end-to-end testing, and supports all modern browsers and platforms.
When coupled with LambdaTest (an AI-powered cloud-based test execution platform) it can be further scaled to run the Playwright scripts in parallel across 3000+ browser and device combinations:

In this quick article we’ll implement a simple “Change my own password” functionality available to the user after they register and log in.
2. Client Side – Change My Password Page
Let’s take a look at the very simple client side page:
<html>
<body>
<div id="errormsg" style="display:none"></div>
<div>
<input id="oldpass" name="oldpassword" type="password" />
<input id="pass" name="password" type="password" />
<input id="passConfirm" type="password" />
<span id="error" style="display:none">Password mismatch</span>
<button type="submit" onclick="savePass()">Change Password</button>
</div>
<script src="jquery.min.js"></script>
<script type="text/javascript">
var serverContext = [[@{/}]];
function savePass(){
var pass = $("#pass").val();
var valid = pass == $("#passConfirm").val();
if(!valid) {
$("#error").show();
return;
}
$.post(serverContext + "user/updatePassword",
{password: pass, oldpassword: $("#oldpass").val()} ,function(data){
window.location.href = serverContext +"/home.html?message="+data.message;
})
.fail(function(data) {
$("#errormsg").show().html(data.responseJSON.message);
});
}
</script>
</body>
</html>3. Update User Password
Let’s now implement the server side operation as well:
@PostMapping("/user/updatePassword")
@PreAuthorize("hasRole('READ_PRIVILEGE')")
public GenericResponse changeUserPassword(Locale locale,
@RequestParam("password") String password,
@RequestParam("oldpassword") String oldPassword) {
User user = userService.findUserByEmail(
SecurityContextHolder.getContext().getAuthentication().getName());
if (!userService.checkIfValidOldPassword(user, oldPassword)) {
throw new InvalidOldPasswordException();
}
userService.changeUserPassword(user, password);
return new GenericResponse(messages.getMessage("message.updatePasswordSuc", null, locale));
}Notice how the method is secured via the @PreAuthorize annotation, since it should only accessible to logged in users.
4. API Tests
Finally, let’s consume the API with some API tests to make sure everything is working fine; we’ll start with the simple configuration of the test and the data initialization:
@ExtendWith(SpringExtension.class)
@ContextConfiguration(
classes = { ConfigTest.class, PersistenceJPAConfig.class },
loader = AnnotationConfigContextLoader.class)
public class ChangePasswordApiTest {
private final String URL_PREFIX = "http://localhost:8080/";
private final String URL = URL_PREFIX + "/user/updatePassword";
@Autowired
private UserRepository userRepository;
@Autowired
private PasswordEncoder passwordEncoder;
FormAuthConfig formConfig = new FormAuthConfig(
URL_PREFIX + "/login", "username", "password");
@BeforeEach
public void init() {
User user = userRepository.findByEmail("[email protected]");
if (user == null) {
user = new User();
user.setFirstName("Test");
user.setLastName("Test");
user.setPassword(passwordEncoder.encode("test"));
user.setEmail("[email protected]");
user.setEnabled(true);
userRepository.save(user);
} else {
user.setPassword(passwordEncoder.encode("test"));
userRepository.save(user);
}
}
}Now – let’s try to change password for a logged in user:
@Test
public void givenLoggedInUser_whenChangingPassword_thenCorrect() {
RequestSpecification request = RestAssured.given().auth()
.form("[email protected]", "test", formConfig);
Map<String, String> params = new HashMap<String, String>();
params.put("oldpassword", "test");
params.put("password", "newtest");
Response response = request.with().params(params).post(URL);
assertEquals(200, response.statusCode());
assertTrue(response.body().asString().contains("Password updated successfully"));
}Next – let’s try to change password given a wrong old password:
@Test
public void givenWrongOldPassword_whenChangingPassword_thenBadRequest() {
RequestSpecification request = RestAssured.given().auth()
.form("[email protected]", "test", formConfig);
Map<String, String> params = new HashMap<String, String>();
params.put("oldpassword", "abc");
params.put("password", "newtest");
Response response = request.with().params(params).post(URL);
assertEquals(400, response.statusCode());
assertTrue(response.body().asString().contains("Invalid Old Password"));
}Finally – let’s try to change password without authentication:
@Test
public void givenNotAuthenticatedUser_whenChangingPassword_thenRedirect() {
Map<String, String> params = new HashMap<String, String>();
params.put("oldpassword", "abc");
params.put("password", "xyz");
Response response = RestAssured.with().params(params).post(URL);
assertEquals(302, response.statusCode());
assertFalse(response.body().asString().contains("Password updated successfully"));
}Note how – for each test – we’re providing a FormAuthConfig to handle the authentication.
We’re also resetting the password via init() to make sure we use the correct password before test.
5. Conclusion
And that’s a wrap – a straightforward way to allow the user to change their own password after registering and logging into the application.
