Tell about your experience in writing and automating UI tests.

In my experience writing UI tests, I used tools like Selenium WebDriver and Cypress. The main task is to automate user interaction scenarios with the interface, verifying the correct display of elements, form functionality, navigation, etc.

For automation, I created tests that open a web page, find elements by selectors, perform actions (clicks, text input), and verify expected results (such as error messages appearing or navigation to another page).

Example in Java using Selenium:

WebDriver driver = new ChromeDriver();
driver.get("https://example.com/login");
WebElement username = driver.findElement(By.id("username"));
username.sendKeys("user1");
WebElement password = driver.findElement(By.id("password"));
password.sendKeys("pass123");
WebElement loginButton = driver.findElement(By.id("loginBtn"));
loginButton.click();

// Check for successful login
assertTrue(driver.getCurrentUrl().contains("dashboard"));
driver.quit();

To improve test stability, I used explicit waits and integrated tests into CI/CD for regular runs and quick regression detection.
