Introduction

This project provides convenient ways to use Pytest within a CMake project. The package can be discovered from a specific range of versions on Linux, macOS or Windows using the find_package function:

find_package(Pytest 8.2.1 REQUIRED)

A pytest_discover_tests() function is provided to simplify automatic testing for C++ projects with Python bindings. It can create CTest tests for each Python test collected within a correct environment:

pytest_discover_tests(
    PythonTest
    LIBRARY_PATH_PREPEND
        $<TARGET_FILE_DIR:MyLibrary>
    PYTHON_PATH_PREPEND
        $<TARGET_FILE_DIR:MyLibrary>
    TRIM_FROM_NAME "^test_"
    DEPENDS MyLibrary
)

Running the tests will display the status for each test collected as follows:

    Start 1: PythonTest.greet_world
1/4 Test #1: PythonTest.greet_world ...........   Passed    0.47 sec
    Start 2: PythonTest.greet_john
2/4 Test #2: PythonTest.greet_john ............   Passed    0.47 sec
    Start 3: PythonTest.greet_julia
3/4 Test #3: PythonTest.greet_julia ...........   Passed    0.47 sec
    Start 4: PythonTest.greet_michael
4/4 Test #4: PythonTest.greet_michael .........   Passed    0.54 sec
