How to Test Back Navigation on Web (Complete Guide)

Testing back navigation on Web apps is crucial to ensure a seamless user experience. When back navigation fails, it can lead to user frustration, increased bounce rates, and ultimately, lost revenue.

Introduction to Back Navigation Testing

Testing back navigation on Web apps is crucial to ensure a seamless user experience. When back navigation fails, it can lead to user frustration, increased bounce rates, and ultimately, lost revenue. Common failures include incorrect page redirects, lost form data, and inconsistent browser behavior. In this guide, we will walk through the importance of back navigation testing, specific test cases, manual and automated testing approaches, and how SUSA tests back navigation autonomously.

What to Test — Specific Test Cases

The following test cases cover happy path scenarios, error scenarios, edge cases, and accessibility considerations:

• Happy Path Scenarios:

+ Navigate to a deep link and press the back button to return to the previous page

+ Fill out a form, submit it, and press the back button to return to the form with preserved data

+ Open a modal window, close it, and press the back button to return to the previous page

• Error Scenarios:

+ Navigate to a page with a broken link and press the back button to return to the previous page

+ Fill out a form with invalid data, submit it, and press the back button to return to the form with error messages

+ Open a modal window with a broken close button and press the back button to return to the previous page

• Edge Cases:

+ Navigate to a page with a hash change (e.g., #anchor) and press the back button to return to the previous page

+ Open a new tab or window and press the back button to return to the previous page

+ Use the browser's back button to navigate through a single-page application (SPA)

• Accessibility Considerations:

+ Test that the back button is accessible via keyboard navigation

+ Test that the back button has a clear and consistent label for screen readers

+ Test that the back button is not trapped in an infinite loop for users with disabilities

Manual Testing Approach

To test back navigation manually, follow these steps:

1. Launch the Web app: Open the Web app in a browser and navigate to a deep link.
2. Press the back button: Press the browser's back button to return to the previous page.
3. Verify the result: Verify that the back button behaves as expected, including preserving form data and redirecting to the correct page.
4. Test edge cases: Test the edge cases listed above, including hash changes, new tabs or windows, and single-page applications.
5. Test accessibility: Test the accessibility considerations listed above, including keyboard navigation, screen reader labels, and infinite loops.

Automated Testing Approach

To automate back navigation testing, use tools like Playwright or Selenium WebDriver. Here's an example using Playwright:

const { test, expect } = require('@playwright/test');

test('back navigation', async ({ page }) => {
  // Navigate to a deep link
  await page.goto('https://example.com/deep-link');

  // Press the back button
  await page.goBack();

  // Verify the result
  await expect(page).toHaveURL('https://example.com/previous-page');
});

You can also use frameworks like Cypress or Jest to write automated tests for back navigation.

How SUSA Tests Back Navigation Autonomously

SUSA tests back navigation autonomously using its 10 user personas, including:

• Curious persona: Tests happy path scenarios, such as navigating to a deep link and pressing the back button.
• Impatient persona: Tests error scenarios, such as filling out a form with invalid data and pressing the back button.
• Elderly persona: Tests accessibility considerations, such as keyboard navigation and screen reader labels.
• Adversarial persona: Tests edge cases, such as hash changes and new tabs or windows.

SUSA's autonomous testing platform can also auto-generate Appium (Android) + Playwright (Web) regression test scripts, including tests for back navigation. With SUSA, you can ensure that your Web app's back navigation behaves as expected, without writing a single line of code. Additionally, SUSA's cross-session learning feature allows it to get smarter about your app every run, providing more accurate and comprehensive test results. By integrating SUSA with your CI/CD pipeline using GitHub Actions, JUnit XML, or the CLI tool (pip install susatest-agent), you can ensure that your Web app's back navigation is thoroughly tested with each build, providing a seamless user experience and reducing the risk of errors and bugs.
