Employee Class from PersonV1
To get started, follow these steps. 1. In Eclipse, import the PersonV2 project. Refer to Import Project in Eclipse if needed for how to use pull and import. 2. Expand PersonV2, src, default package in the Eclipse Package Explorer. 3. Open up StudentTest and expand the comments at the top of the top. Follow the steps in the comments to add the JUnit 5 library to your build path. 4. Verify that you can run StudentTest successfully. 5. Open Student and review how the constructors only makes calls to super, this, or setters. 6. Review the setters in Student and review how they throw IllegalArgumentExceptions for any attempt to provide invalid data. 7. Open StudentTest to review how the various tests are implemented. 8. In PersonV1, open up your original Employee class, select all and copy the text, then close Employee. 9. In Personv2, open up the new Employee class and replace everything with what you copied in the previous step. 10. If necessary, set up your constructors so they only make calls to super, this, or setters. Do not directly assign any values to any variables. 11. Modify setEmployeeld and add checks to prevent the user from setting the value to null. Require the value to start with the letter E and be exactly 9 characters long. 12. Modify setDepartment and add checks to prevent the user from setting the value to null or "". 13. Open up EmployeeTest. Using StudentTest as a guide, create the necessary constants and methods to test your Employee class. 14. In Package Explorer, right-click on PersonV2 and choose Team > Commit... 15. In the Stages Changes folder, you should see Employee.java and EmployeeTest.java. 16. Enter a brief message in the Commit Message box. 17. If necessary, enter your email in the Author and Committer boxes. 18. Press Commit and Push... 19. You should see a dialog box indicating the commit was successful. If you run into problems at this step, contact your instructor 20. Access the csem.cc option in the navigation menu, log in, and run the PersonV2 test. If necessary, make additional changes, commit those changes, and run the test again. * setup Student Test.java Employee Test.java X 10/ * 2 * Add Libraries... 20 2. In the list of libraries, choose JUnit then press Next. 21 3. For the library version, choose JUnit 5 then press Finish. 22 */ 23 24e fimport static org. junit.
