Please, specify the path where your TripPlannerJunit is located.
If this is the current folder of a project:
java -cp .;Z:\lib\junit-4.12.jar;...
or
java -cp %CD%;Z:\lib\junit-4.12.jar;...
UPDATE based on clarification in comments.
Assumed you have this structure:
Z:\TripPlanner\lib\
| hamcrest-core-1.3.jar
| junit-4.12.jar
|
+---com
| \---example
| \---tests
| TripPlannerJunit.java
| TripPlannerJunit.class
Run the test from Z:\TripPlanner\lib folder:
Z:\TripPlanner\lib>java -cp .;junit-4.12.jar;hamcrest-core-1.3.jar org.junit.runner.JUnitCore "com.example.tests.TripPlannerJunit"
