Making Simplex Project Testing - Clean and Simple

• What does this repo do?

  • It organizes the python stack for the coding project

• What do I need to do in the project?

  • The project aim is to complete 3 functions using the revised simplex method
  • These are simplex_step, simplex_init, and simplex_method
  • The details of what these functions do and what are the inputs and outputs are available in project.pdf file provided.
  • The instructors will run the functions for different test cases (1-11)

• Okay, then how is this repository related to project?

  • Find project.py file. This is the only file where you make changes.
  • You'll find those 3 functions in this file, just add the appropriate code in there
  • Once done, you can test your implementation using run_test.py and verify if your implementation is correct.
  • Every test file provided by the instructor tests different aspects of the simplex implementation, so to make things simple, the run_test.py by itself will find the appropriate test case - run your function and then let you know the result (success/fail)
  • There's more, groot also checks if your function return types are valid, so that you know that you have the right construction
  • Beyond that, groot is very flexible in terms of testing, you can test by test_number, function or all cases in one go.

• "Uhhh.. that seems to complicated, tell me bottom line?"

  • Just go to project.py file and write your code.

  • Say, you've finished simplex_step and want to see if this is correct.

    • On your console run - python3 run_test.py --function=simplex_step

  • OR say you just want to run test3 for debugging sake

    • On your console run - python3 run_test.py --test=3
    • OR may be you're done with all 3 functions and run all the test cases
      • On your console run - python3 run_test.py --all

  • Nice! What do I get after running this?

    • Groot tells you if your output were correct/incorrect and if latter then what part of the output is incorrect. Like this:

    $python run_test.py --function="simplex_step"
    
    ************************************
    TEST-1
    ************************************
    INCORRECT STEP!
    iN incorrect!
    iB incorrect!
    
    >> TEST - 2 was successful! 
    >> TEST - 3 was successful!
    >> TEST - 4 was successful!
    ************************************
    TEST-5
    ************************************
    INCORRECT istatus!
    

  • Do I need to do anything with the test_scripts - No

  • Do I need to make any changes in run_test.py - No, you only modify project.py

  • How do I find all the execution options - python3 run_tests.py --help

1. Jupyter-notebook support
2. Debug mode and pretty printing - under way
