A semi-automatic tester for checking 42's philosophers project. It tests: invalid inputs, when program should stop on death/eaten enough, and when program should stay running (timed).

Lazy Philosophers Tester

A semi-automatic tester for checking 42's philosophers project (2021 curriculum).
It allows you to test 2 scenarios:

1. when your program should stop, either due to death, enough eaten, or bad input
   • to be checked manually by the user, based on the expected result listed in yes-die.txt.
2. when no philosophers should die
   • this is checked automatically if the program runs for x seconds (default 10) without death.

More tests can be added by editing the appropriate .txt files with the input and expected outcome.

Installation

Clone the tester into the root directory of your philosophers project.

https://github.com/MichelleJiam/LazyPhilosophersTester.git

Usage

If you haven't already, run make in your philo directory to create your ./philo executable.
Then from within the LazyPhilosophersTester directory, run ./test.sh to start the tester.
Tester takes an optional 2nd argument of the path to your philo executable.

Example:

./test.sh ../philo

If not provided, the tester assumes the path is ../philo - i.e. in same directory as tester directory.

Adding tests

If you wish to add your own tests, open either:

1. no-die.txt for tests where philos aren't supposed to die, or
2. yes-die.txt for tests where the program should stop (death, eaten enough, error).

The 1st line should be your test case, separated by spaces. This is what is inputted into your program.
The 2nd line should be the expected outcome. This is outputted during the tester for checking purposes.

Example:

4 310 200 100
a philo should die
5 800 200 200 7
no one should die, simulation should stop after 7 eats

Progress bar function written by Vagiz Duseev, found on StackOverflow.

lazyphilosopherstester's Issues

Python script not working with bonus

Python timing script doesn't currently detect bonus program due to calling killall() on "philo" program.
Need to change to call it on bonus program if run from within bonus folder.

Syntaxe Error in PhilosophersChecker.py

Syntaxe Error in "PhilosophersChecker.py" in all print statement

`SIGTERM: no process found` even though test is OK
