    @Take a look at
    public void testAddition() {
        Calculator calculator = new Calculator();
        int outcome = calculator.add(2, 3);
        assertEquals(5, outcome);

On this instance, the Calculator class is examined by verifying that the add() technique appropriately provides two numbers. Unit exams present fast suggestions on code correctness and assist catch bugs early on.

Integration Testing:

Integration testing verifies the interplay and interoperability between a number of elements or methods. It ensures that completely different modules or providers work collectively as anticipated. Right here’s an instance of an integration check utilizing the Spring Boot framework:

import org.junit.jupiter.api.Take a look at;
import org.springframework.beans.manufacturing facility.annotation.Autowired;
import org.springframework.boot.check.context.SpringBootTest;

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class UserControllerIntegrationTest {
    non-public TestRestTemplate restTemplate;

    @Take a look at
    public void testGetUserById() {
        String response = restTemplate.getForObject("/customers/{id}", String.class, 1);
        // Carry out assertions on the response

This instance demonstrates an integration check for a consumer controller in a Spring Boot software. It makes use of a check REST template to work together with the appliance’s endpoints and validate the response.

Practical Testing:

Practical testing verifies that the appliance’s options, consumer interfaces, and workflows behave as supposed primarily based on the practical necessities. It ensures that the system features appropriately from the end-user’s perspective. Right here’s an instance utilizing Selenium for net software testing:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.By;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Take a look at;
import static org.junit.jupiter.api.Assertions.assertEquals;

public class LoginPageTest {
    non-public WebDriver driver;

    public void setUp() {
        System.setProperty("", "path/to/chromedriver");
        driver = new ChromeDriver();

    public void tearDown() {

    @Take a look at
    public void testLogin() {
        WebElement usernameInput = driver.findElement("username"));
        WebElement passwordInput = driver.findElement("password"));
        WebElement loginButton = driver.findElement("loginButton"));

        passwordInput.sendKeys("password"); on();

        String currentUrl = driver.getCurrentUrl();
        assertEquals("", currentUrl);

This instance demonstrates a practical check utilizing Selenium WebDriver. It navigates to a login web page, enters credentials, clicks the login button, and verifies that the consumer is redirected to the dashboard web page.

Efficiency Testing:

Efficiency testing evaluates the appliance’s efficiency and responsiveness beneath numerous circumstances, comparable to excessive load, stress, or concurrent consumer exercise. It helps determine efficiency bottlenecks, scalability points, and efficiency degradation. Right here’s an instance utilizing JMeter for load testing:

  1. Begin by creating a brand new Take a look at Plan in JMeter.
  2. Add a Thread Group to the Take a look at Plan. Set the variety of threads (digital customers) and ramp-up interval (time to start out all threads) in response to your required load state of affairs.
  3. Throughout the Thread Group, add an HTTP Request sampler to simulate the requests to the online software. Specify the goal URL, technique (GET, POST, and so forth.), and any vital parameters.
  4. Configure extra settings for the HTTP Request, comparable to headers, cookies, and assertions.
  5. To simulate real looking consumer habits, you possibly can add extra elements like HTTP Cookie Supervisor, HTTP Header Supervisor, and Cache Supervisor.
  6. Add listeners to gather and analyze the check outcomes. JMeter offers numerous listeners, comparable to Abstract Report, Mixture Report, and View Outcomes Tree.
  7. Configure the specified load state of affairs by adjusting the check period, ramp-up time, and different related settings within the Thread Group.
  8. Save the Take a look at Plan and run the load check by clicking the “Begin” or “Run” button.

JMeter will then simulate a number of concurrent customers, sending requests to the online software as per the outlined load state of affairs. The listeners will gather knowledge on response instances, throughput, error charges, and different efficiency metrics.

This instance demonstrates how JMeter can be utilized to evaluate the efficiency and scalability of an online software by simulating numerous consumer hundreds. By analyzing the check outcomes, you possibly can determine efficiency bottlenecks, tune system assets, and optimize the appliance’s efficiency beneath completely different load circumstances.

import org.apache.jmeter.threads.ThreadGroup
import org.apache.jmeter.reporters.ResultCollector
import org.apache.jmeter.reporters.Summariser
import org.apache.jmeter.util.JMeterUtils

// Initialize JMeter

// Create a Take a look at Plan
def testPlan = new org.apache.jmeter.testelement.TestPlan("Take a look at Plan")
testPlan.setProperty("title", "My Load Take a look at")

// Create a Thread Group
def threadGroup = new ThreadGroup()
threadGroup.setName("Thread Group")
threadGroup.setNumThreads(100) // Variety of threads
threadGroup.setRampUp(60) // Ramp-up interval in seconds

// Create a Loop Controller
def loopController = new LoopController()
loopController.setLoops(5) // Variety of loops

// Create an HTTP Request Sampler
def httpRequest = new HTTPSamplerProxy()

// Assemble the Take a look at Plan

// Add End result Collector for check outcome logging
def resultCollector = new ResultCollector(new Summariser())

// Save the Take a look at Plan to a JMX file
def saveService = SaveService.getInstance()
saveService.saveTree(testPlan, new FileOutputStream("path/to/test-plan.jmx"))

// Run the Take a look at Plan
def jmeter = new StandardJMeterEngine()

This instance demonstrates how one can programmatically create a primary JMeter load check script utilizing Groovy. It units up a Take a look at Plan, Thread Group, Loop Controller, and an HTTP Request Sampler. It additionally provides a End result Collector for logging the check outcomes. Lastly, it saves the Take a look at Plan to a JMX file and executes it utilizing the JMeter engine.
