how to create an autograder for my java code (test cases provided)?

I am enrolling the data structures course on coursera. It is a specialization, but I only take the data structures independently. However, I can only submit the programming assignment if I upgrade to the entire specialization...

Within the directory of the assignment, there is also a subdirectory containing a bunch of test cases (eg. test01 <---- the test file input, and test01.a <---- the expected result). I wonder how can I to test my source code using those test cases, like the online autograder? (write a bash shell script, use JUnit, etc.)

Thanks!
