This collection of functional tests depends on a mixture of Pexpect and pytest. pytest is used as a framework to run the entire collection and Pexpect is used to execute the CLI and make assertions on the output.

⚠️ To keep the tests cross-platform friendly, we use Pexpect's PopenSpawn instead of the more heavily documented spawn. See "Pexpect on Windows" for more details on the limitations.

• Python 3.x
• A built executable named smartthings/smartthings.exe installed on the system PATH environment variable.

A good way to ensure the modules needed here don't interfere with other python projects you might have (and vice versa) is to use a virtual python environment for running tests. You can do this using the venv module.

1. cd smartthings-cli/packages/cli/functional-tests
2. python -m pip install --upgrade pip
3. pip install -r requirements.txt
4. pytest
