Read the specification document thoroughly. Create a high level design covering all scenarios / test cases before you start coding. How do I run only the CRUD tests ? $ make clean $ make $ ./Application ./testcases/create.conf or $ ./Application ./testcases/delete.conf or $ ./Application ./testcases/read.conf or $ ./Application ./testcases/update.conf How do I test if my code passes all the test cases ? Run the grader. Check the run procedure in KVStoreGrader.sh
