We have checked the navigation contents in interface testing. But to ensure the functioning of correct sequence of those navigation, navigation testing is performed on various possible paths in the web application. Design the test cases such that the following navigation are correctly executing:

1. Internal links
2. External links
3. Redirected links
4. Navigation for searching inside the web application

The errors must be checked during navigation testing for the following:

1. The links should not be broken due to any reason.
2. The redirected links should be with proper messages displayed to the user.
3. Check that all possible navigation paths are active.
4. Check that all possible navigation paths are relevant.
5. Check the navigation for the back and forward buttons, whether they are working properly.
