* TestStruct::
* testcase_id [long] ID of the test-case
* testcase_input_path [String] File path to test-case input
* testcase_output_path [String] File path to test-case output generated by the problem solver
* testcase_expected_output_path [String] File path to test-case expected output to be matched with
* metadata_file_paths [ArrayList<String>] File paths to Question metadata (Extra files usually used for defining traning sets)
* submission_code_path [String] File path to submission source code
* testcase_result [boolean] Set to true if test-case output matches test-case expected output. Matching is done line by line
* testcase_signal [long] Exit code of the test-case process
* testcase_time [double] Time taken by the test-case process in seconds
* testcase_memory [long] Peak memory of the test-case process determined in bytes
* data [String] <Future use>
*
*
* ResultStruct::
* result [boolean] Assign test-case result. true determines success. false determines failure
* score [double] Assing test-case score. Normalized between 0 to 1
* message [String] Assing test-case message. This message is visible to the problem solver

Testing:
Input file data. Path to be passed as command line argument

{"testcase_id":0,"input_file_path":"/run-XX/input00.txt","output_file_path":"/run-XX/output00.out","expected_output_file_path":"/run-XX/output_expected00.out","metadata_file_paths":["/run-XX/training.txt","/run-XX/training2.txt"],"submission_code_path":"/run-XX/solution.cpp", "testcase_result":true,"testcase_signal":0,"testcase_time":1.2,"testcase_memory":312322,"data":"Data"}

Expected output:
