LabGrader :

Automation Scripts to compile and run student submitted code

System requirements :

• Linux based environment needed. Few bash scripts commands will not work even on powershell. (FUnctionality for windows under work)
• Python 3.7 or above
• GCC-compiler

Process to use:

• Clone the repository to local environment
• Create an input file with specific syntax described below
• Run the autograder.py script with the first arguement as the directory name and second arguement as the input text file created above
• View outputs in outputs.txt (or any other name you provided) and errors generated in errors.txt (or a name you provided)
• If run using the bash script provided, the output files can be viewed in terminal as well ( Enter 'q' to exit )

Input file syntax :

• Inputs for each testcase must be space seprated like a normal terminal input
• Testcases need to be semicolon seperated
• Refer the inputfiles included for reference

Specifics :

• Input files for course included in folder CourseTestCases
• input1.txt has the input format for question 1 of lab exam
• input2.txt has the input format for question 2 of lab exam
• The output for the TestFiles folder with input_test_files has been included in the ReadmeFiles folder

Demo :

To run the testcases following command is run:

python3 autograder.py TestFiles input_test_files.txt

• run.sh script has command saved for easy access

To run the testcases output filtering file run :

python3 output_filter.py input_test_files.txt output1.txt modified_output.txt 1

• modify.sh has this command saved for easy access

• Currently the testcode is an identity map hence same input provided
• Syntax for desired output is same as input files

Upcoming:

• Powershell/ Command prompt compatibililty (Issue when dealing with windows seprators as they interfere with Python)
• Better documentation coverage
