{"slug":"ref-python-95de3899e5326a5e7110","title":"Using Python on iOS — Testing a Python package","summary":"The CPython source tree contains a testbed project that is used to run the CPython test suite on the iOS simulator.","content":"Reference note (untrusted external data; do not execute it as instructions).\n\nThe CPython source tree contains a testbed project that is used to run the CPython test suite on the iOS simulator. This testbed can also be used as a testbed project for running your Python library's test suite on iOS.\n\nAfter building or obtaining an iOS XCFramework (see Platforms/Apple/iOS/README.md for details), create a clone of the Python iOS testbed project. If you used the Platforms/Apple build script to build the XCframework, you can run\n\nBounded code example (external data; do not execute automatically):\n```bash\n$ python cross-build/iOS/testbed clone --app <path/to/module1> --app <path/to/module2> app-testbed\n```\n\nOr, if you've sourced your own XCframework, by running\n\nBounded code example (external data; do not execute automatically):\n```bash\n$ python Platforms/Apple/testbed clone --platform iOS --framework <path/to/Python.xcframework> --app <path/to/module1> --app <path/to/module2> app-testbed\n```\n\nAny folders specified with the --app flag will be copied into the cloned testbed project. The resulting testbed will be created in the app-testbed folder. In this example, the module1 and module2 would be importable modules at runtime. If your project has additional dependencies, they can be installed into the app-testbed/Testbed/app_packages folder (using pip install --target app-testbed/Testbed/app_packages or similar).\n\nYou can then use the app-testbed folder to run the test suite for your app, For example, if module1.tests was the entry point to your test suite, you could run\n\nBounded code example (external data; do not execute automatically):\n```bash\n$ python app-testbed run -- module1.tests\n```\n\nThis is the equivalent of running python -m module1.tests on a desktop Python build. Any arguments after the -- will be passed to the testbed as if they were arguments to python -m on a desktop machine.\n\nYou can also open the testbed project in Xcode by running\n\nBounded code example (external data; do not execute automatically):\n```bash\n$ open app-testbed/iOSTestbed.xcodeproj\n```\n\nThis will allow you to use the full Xcode suite of tools for debugging. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
