- testfiles	<path>: 	The path of the directory containing the test files that were supplied with this test.
- interface 	[c|py|both]:	Specifies the interface you want to test.
- regular 	[yes|no]:	Specifies whether to run the regular tests or not.
- leaks		[yes|no]:	Specifies if you want memory leak tests. Applies to the \e[4;37m\e[1;37mC\e[0m interface only.
- efficiency	[yes|no]:	Specifies whether you want an efficiency test on the interfaces you chose.
- results_dir	<path>:		Creates a new directory to store the tests' results into (default: running directory).

\e[4;37m\e[1;37mNotes\e[0m: 
(1) The efficiency tests are quite long, take that into account.
(2) Detailed regular tests' results are saved into \`\033[4;37mtest_transcript_<interface>.txt\e[0m\`.
(3) Detailed memory leak tests' results are saved into \`\033[4;37mmemory_transcript_c.txt\e[0m\`.
(4) Detailed Efficiency tests' results are saved into \`\033[4;37mefficiency_transcript_<interface>.txt\e[0m\`.
(5) Only failed tests' results are saved into their transcript.
(6) Efficiency tests become invalid when running on tau-related server (e.g., nova).

\e[4;37m\e[1;37mInstructions\e[0m:
(1) Avoid any build/dist/egg directories/files from the working directory. Could potentially lead to undefined behaviors of the test script.
(2) You shall run this shell script from within the directory that contains all of the files that you need to assign.
(3) You shall have the package \`\e[4;37mvalgrind\e[0m\` installed if you wish to run memory leak tests.
(4) You shall have the python packages \`\e[4;37mnumpy\e[0m\` and \`\e[4;37mscikit-learn\e[0m\` installed if you wish to run efficiency tests."
