Alert accept and dismiss in Selenium Java - Test Execution Trace

Test Overview

This test opens a web page with a JavaScript alert, then it accepts the alert and verifies the confirmation message. Next, it triggers a confirm alert, dismisses it, and verifies the cancellation message.

Test Code - JUnit with Selenium WebDriver

public class AlertAcceptDismissTest {
    WebDriver driver;

    @BeforeEach
    public void setUp() {
        driver = new ChromeDriver();
        driver.get("https://the-internet.herokuapp.com/javascript_alerts");
    }

    @Test
    public void testAlertAcceptAndDismiss() {
        // Click button to trigger alert
        driver.findElement(By.xpath("//button[text()='Click for JS Alert']")).click();

        // Switch to alert and accept it
        Alert alert = driver.switchTo().alert();
        alert.accept();

        // Verify result text after accepting alert
        String resultText = driver.findElement(By.id("result")).getText();
        assertEquals("You successfully clicked an alert", resultText);

        // Click button to trigger confirm alert
        driver.findElement(By.xpath("//button[text()='Click for JS Confirm']")).click();

        // Switch to alert and dismiss it
        Alert confirmAlert = driver.switchTo().alert();
        confirmAlert.dismiss();

        // Verify result text after dismissing confirm alert
        String confirmResult = driver.findElement(By.id("result")).getText();
        assertEquals("You clicked: Cancel", confirmResult);
    }

    @AfterEach
    public void tearDown() {
        driver.quit();
    }
}
