The type org.junit.After is not accessible

This error message indicates that the Java class "org.junit.After" is not accessible, which means that the code is not able to use this class. This can occur for a variety of reasons, such as:

- The JUnit library is not properly installed or configured in the project
- The version of JUnit being used does not include the "After" annotation
- The class or method is marked as private or protected and cannot be accessed from outside its package or class

To resolve this issue, you may need to check your project dependencies and make sure that JUnit is properly installed and configured. You may also need to check the version of JUnit being used and make sure that it includes the "After" annotation. If the class or method is marked as private or protected, you may need to change the access modifier to public or find a different way to access it from outside its package or class.
