Navigation (back, forward, refresh) in Selenium Java - Test Execution Trace

Test Overview

This test opens a website, navigates to another page, then uses browser navigation commands: back, forward, and refresh. It verifies the page titles after each navigation step to confirm correct behavior.

Test Code - JUnit with Selenium WebDriver

Selenium Java

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.junit.jupiter.api.*;
import static org.junit.jupiter.api.Assertions.*;

public class NavigationTest {
    static WebDriver driver;

    @BeforeAll
    public static void setup() {
        driver = new ChromeDriver();
    }

    @Test
    public void testNavigationBackForwardRefresh() {
        driver.get("https://example.com");
        String firstPageTitle = driver.getTitle();

        driver.navigate().to("https://example.com/more-info");
        String secondPageTitle = driver.getTitle();

        driver.navigate().back();
        String backPageTitle = driver.getTitle();
        assertEquals(firstPageTitle, backPageTitle, "Back navigation should return to first page");

        driver.navigate().forward();
        String forwardPageTitle = driver.getTitle();
        assertEquals(secondPageTitle, forwardPageTitle, "Forward navigation should go to second page");

        driver.navigate().refresh();
        String refreshedTitle = driver.getTitle();
        assertEquals(secondPageTitle, refreshedTitle, "Refresh should keep the same page title");
    }

    @AfterAll
    public static void teardown() {
        if (driver != null) {
            driver.quit();
        }
    }
}

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Browser window is open, no page loaded yet	—	PASS
2	Navigate to https://example.com	Browser displays the example.com homepage	Page title is captured as firstPageTitle	PASS
3	Navigate to https://example.com/more-info	Browser displays the more-info page	Page title is captured as secondPageTitle	PASS
4	Navigate back to previous page	Browser displays the example.com homepage again	Assert page title equals firstPageTitle	PASS
5	Navigate forward to more-info page	Browser displays the more-info page again	Assert page title equals secondPageTitle	PASS
6	Refresh the current page	Browser reloads the more-info page	Assert page title equals secondPageTitle	PASS
7	Test ends and browser closes	Browser window is closed	—	PASS

Failure Scenario

Failing Condition: Page title after navigation does not match expected title

Execution Trace Quiz - 3 Questions

What does the test verify after calling driver.navigate().back()?

A The page title matches the first page visited

B The browser closes

C The page URL changes to a new site

D The page content is refreshed

Key Result

Always verify page titles or unique page elements after navigation commands to ensure the browser is on the expected page.

Practice

1. What does the driver.navigate().back() method do in Selenium WebDriver?

easy

A. It closes the browser window.

B. It navigates the browser to the previous page in history.

C. It navigates the browser to the next page in history.

D. It refreshes the current page.

Solution

1. Step 1: Understand the back() method

   The back() method simulates clicking the browser's back button, moving to the previous page in history.

2. Step 2: Compare with other navigation methods

   forward() moves forward, refresh() reloads the page, and closing the browser is done by driver.close().

3. Final Answer:

   It navigates the browser to the previous page in history. -> Option B

4. Quick Check:

   back() = previous page [OK]

Hint: Back() always goes to the previous page in browser history [OK]

Common Mistakes:

• Confusing back() with refresh()
• Thinking back() closes the browser
• Mixing back() with forward()

2. Which of the following is the correct syntax to refresh the current page using Selenium WebDriver in Java?

easy

A. driver.navigate().refresh();

B. driver.refresh();

C. driver.navigate().reload();

D. driver.refreshPage();

Solution

1. Step 1: Recall the refresh method syntax

   In Selenium Java, refreshing the page is done by calling driver.navigate().refresh();.

2. Step 2: Eliminate incorrect options

   driver.refresh(), driver.navigate().reload(), and driver.refreshPage() are not valid Selenium WebDriver methods.

3. Final Answer:

   driver.navigate().refresh(); -> Option A

4. Quick Check:

   refresh() method is under navigate() [OK]

Hint: Use navigate().refresh() to reload the page [OK]

Common Mistakes:

• Using driver.refresh() directly
• Using non-existent reload() method
• Confusing refresh with back or forward

3. Consider the following Selenium Java code snippet:

driver.get("https://example.com/page1");
driver.get("https://example.com/page2");
driver.navigate().back();
String currentUrl = driver.getCurrentUrl();

What will be the value of currentUrl after execution?

medium

A. "https://example.com/home"

B. "https://example.com/page2"

C. "https://example.com/page1"

D. Throws an exception

Solution

1. Step 1: Trace navigation steps

   The driver first opens page1, then page2. Calling navigate().back() moves back to page1.

2. Step 2: Check current URL after back()

   After going back, getCurrentUrl() returns the URL of page1.

3. Final Answer:

   "https://example.com/page1" -> Option C

4. Quick Check:

   back() returns to previous URL [OK]

Hint: Back() returns to the last visited URL [OK]

Common Mistakes:

• Assuming current URL stays on page2
• Expecting an exception on back()
• Confusing back() with refresh()

4. Identify the error in the following Selenium Java code snippet:

driver.get("https://example.com");
driver.navigate().forward();
String url = driver.getCurrentUrl();

What is the problem?

medium

A. driver.get() should be replaced with driver.navigate().to().

B. Syntax error in navigate().forward() method call.

C. driver.getCurrentUrl() returns null after forward().

D. Calling forward() without a previous back() navigation does nothing.

Solution

1. Step 1: Understand forward() behavior

   The forward() method moves forward in browser history only if there is a forward page available.

2. Step 2: Analyze code context

   Since no back() was called before, there is no forward page, so forward() does nothing.

3. Final Answer:

   Calling forward() without a previous back() navigation does nothing. -> Option D

4. Quick Check:

   forward() needs prior back() [OK]

Hint: Use back() before forward() to enable forward navigation [OK]

Common Mistakes:

• Expecting forward() to always change page
• Thinking forward() causes syntax error
• Confusing get() and navigate().to()

5. You want to test that after navigating back and then forward, the browser returns to the original page URL. Which sequence of Selenium Java commands correctly achieves this?

hard

A. driver.navigate().back(); driver.navigate().forward(); String url = driver.getCurrentUrl();

B. driver.navigate().forward(); driver.navigate().back(); String url = driver.getCurrentUrl();

C. driver.navigate().refresh(); driver.navigate().back(); String url = driver.getCurrentUrl();

D. driver.navigate().back(); driver.navigate().refresh(); String url = driver.getCurrentUrl();

Solution

1. Step 1: Understand navigation flow

   To test returning to the original page, first go back, then forward to return to the original page.

2. Step 2: Verify correct command order

   driver.navigate().back(); driver.navigate().forward(); String url = driver.getCurrentUrl(); correctly calls back() then forward(), then gets the current URL.

3. Final Answer:

   driver.navigate().back(); driver.navigate().forward(); String url = driver.getCurrentUrl(); -> Option A

4. Quick Check:

   Back then forward returns to original URL [OK]

Hint: Back then forward returns to original page URL [OK]

Common Mistakes:

• Calling forward() before back()
• Using refresh() instead of forward()
• Not checking URL after navigation
