What is being tested

  • Inputs, outputs and errors are compared with the school's solution
  • Valgrind is also used(valgrind issues don't cause the tests to fail, they're simply emitted to the tester's STDERR)

How to understand errors

  • Each test case corresponds to a different .csv file that's tested, and the file's name should indicate what's wrong in case of invalid input files. The output of failed tests will be mismatches between your output and the output of the school solution(a diff)

Requirements

  • A HUJI system is guaranteed to work

  • A x64 Debian based Linux distribution with python3.7 or higher, along with the pytest library might work too, but I haven't tested it.

    Windows isn't supported

  • IMPORTANT

    Compiled executable is assumed to live in the cmake-build-debug folder of your root project, and the executable is named FractalDrawer

    If that isn't the case, you may need to modify your CMakeLists.txt to ensure it creates an executable with this name. Here's an example of such CMakeLists:

    cmake_minimum_required(VERSION 3.10)
project(FractalDrawer)

set(CMAKE_CXX_STANDARD 14)

find_package(Boost COMPONENTS filesystem REQUIRED)
include_directories(${Boost_INCLUDE_DIR})

add_executable(FractalDrawer FractalDrawer.cpp Fractal.cpp Fractal.h)
target_link_libraries(FractalDrawer ${Boost_LIBRARIES})
target_compile_options(FractalDrawer PRIVATE -Wall -Wextra -Werror -Wvla)

Installation

  1. Clone this repository into a 'tests' directory within your project's root folder, this can be done via the command

    git clone https://github.cs.huji.ac.il/danielkerbel/test_cpp_ex2 tests

    (This may ask you for your CSE user credentials)

  2. Set a 'pytest' run configuration in PyCharm/CLion for the tester: Run | Edit Configurations | + | Python tests | pytest

Under Target, select the Module Name option, and write tester in the text-box below

  1. If using CLion, you might want to set a python interpreter as well by going to File | Settings | Build, Execution, Deployment | Python Interpreter and changing from <No Interpreter> to Python 3.7 (or higher). This isn't necessary in PyCharm.

    • Note: I don't recommend using CLion for running the tests, as it doesn't format errors as good as PyCharm.(PyCharm can display a <Click to see differences> link that will open a nice graphical diff tool)

Running

  1. Firstly, compile your FractalDrawer executable using CLion/terminal(at the cmake-build-debug folder) (Make sure it's named FractalDrawer as explained in the requirements section)

  2. Run the python tester via one of the following ways:

    • Graphically, by doing Run | Run... | pytest for tester
    • Via terminal, by doing python3 PROJECT_ROOT/tests/tester.py

Tips

  • You can set USE_VALGRIND to False at tester.py line 11, this will cause tests to run quicker. (Don't forget to eventually enable it)
