LFTracer

Midterm exam problem for KNU SE Spring 2023 (Line visit counter).

Requirements

R1. Count the number of visiting for each statement in the target functions.
R2. Write your LFTracer.py in the repository.
R3. Test your LFTracer.py by using pytest.
R4. You need to let your TA know your repository URL and your student ID together.
R5. LFTracer class should be defined in the LFTracer.py
R6. The above class is tested as:

def test_lf_sha256():
    with LFTracer(target_func = ["generate_hash", "_sigma0"]) as traced:
        encoded = "mysalt".encode()
        generate_hash(encoded).hex()

    answer = ...
    assert traced.getLFMap() == answer

R7. LFTracer should count the number of visiting for each statement in each target functions. - The target functions should be specified by target_func = ["func1", "func2"].
R8. There is a member function called “getLFMap()” in LFTracer, which returns a dictionary of {“func1”: {1: x1, 2: y1, ...}, “func2”: {1: x2, 2: y2, ...}, …}.
R9. "target_function" can be called multiple times.
R10. To run some test cases given, you should install necessary pacakges listed in requirements.txt.
