When testing pagination on a Single-Page Application (SCA) website, you’ll want to cover various scenarios to ensure the functionality works as expected. Here are some test cases you can consider for pagination testing:
- Initial Page Load:
- Verify that the initial page load displays the correct number of items per page as configured in the application settings.
- Confirm that the pagination controls are visible and correctly positioned on the page.
- Navigation Buttons:
- Test the “Next” button to ensure it correctly takes you to the next page.
- Test the “Previous” button to ensure it correctly takes you to the previous page.
- Verify that these buttons are disabled appropriately when you are on the first or last page.
- Page Number Navigation:
- Check if you can navigate to a specific page by entering a valid page number.
- Verify that entering an invalid page number or a non-numeric value results in an appropriate error message.
- Page Size Configuration:
- Confirm that changing the number of items per page in the settings updates the pagination accordingly.
- Verify that the pagination is still functional after changing the page size.
- Data Consistency:
- Ensure that the data displayed on each page is accurate and corresponds to the selected page number.
- Check if the total number of items is consistent across all pages.
- Sorting and Filtering:
- Test pagination in conjunction with sorting and filtering options to ensure they work seamlessly together.
- Verify that changing the sorting or filtering options updates the pagination correctly.
- Edge Cases:
- Test pagination with a very large dataset to ensure performance and scalability.
- Verify that pagination still works when there are no items to display or only a few items.
- Browser Compatibility:
- Test pagination on different browsers (Chrome, Firefox, Safari, Edge, etc.) to ensure cross-browser compatibility.
- Check responsiveness and usability on various devices (desktop, tablet, mobile).
- Error Handling:
- Test the application’s behavior when there are network issues or server errors during pagination requests.
- Verify that error messages are displayed appropriately, and the user experience is not compromised.
- Security:
- Ensure that pagination requests are properly validated on the server side to prevent potential security vulnerabilities like SQL injection.
- Localization:
- If the application supports multiple languages, test pagination with different language settings.
