pytest-cpp

Use pytest runner to discover and execute C++ tests.

Supports Google Test, Boost.Test, and Catch2:

This brings several benefits:

Allows you to run all your tests in multi-language projects with a single command;
Execute C++ tests in parallel using pytest-xdist plugin;
Use --junitxml option to produce a single and uniform xml file with all your test suite results;
Filter which tests to run using standard test filtering capabilities, such as by file names, directories, keywords by using the -k option, etc.;

Installation

Install using pip:

$ pip install pytest-cpp

Usage

$ pytest

Once installed, pytest runs will search and run tests found in executable files, detecting if the suites are Google, Boost, or Catch2 tests automatically.

Configuration Options

Following are the options that can be put in the pytest configuration file related to pytest-cpp.

cpp_files

You can configure which files are tested for suites by using the cpp_files ini configuration option:

[pytest]
cpp_files = test_suite*

By default matches test_* and *_test executable files.

cpp_arguments

Arguments to the C++ tests can be provided with the cpp_arguments ini configuration option.

For example:

[pytest]
cpp_arguments =-v --log-dir=logs

You can change this option directly in the command-line using pytest's -o option:

$ pytest -o cpp_arguments='-v --log-dir=logs'

Important: do not pass filtering arguments (for example --gtest_filter), as this will conflict with the plugin functionality and behave incorrectly.

To filter tests, use the standard pytest filtering facilities (such as -k).

cpp_ignore_py_files

This option defaults to True and configures the plugin to ignore *.py files that would otherwise match the cpp_files option.

Set it to False if you have C++ executable files that end with the *.py extension.

[pytest]
cpp_ignore_py_files = False

cpp_harness

This option allows the usage of tools that are used by invoking them on the console wrapping the test binary, like valgrind and memcheck:

[pytest]
cpp_harness = valgrind --tool=memcheck

cpp_harness_collect

This option allows the usage of tools or emulators (like wine or qemu) that are used by invoking them on the console wrapping the test binary during a test collection.

Might be used in the combination with cpp_harness to run a binary in emulators, like wine or qemu in cross-compilation targets.

[pytest]
cpp_harness_collect = qemu-x86_64 -L libs/

or

[pytest]
cpp_harness_collect = qemu-x86_64 -L libs/
cpp_harness = qemu-x86_64 -L libs/
