# Run SDK tests

This document describes how to create a dev environment in order to run SDK tests
or execute the various commands available in the toolbox.

## Set up a virtual environment

1.  If you don't already have it, install Python:

    - Windows: [Python website][python_website] or from the [Windows store][python_312]
    - Ubuntu/Debian `sudo apt-get install python3`
    - RHEL/CentOS `sudo yum install python3`

    Python is also available in Bash for Windows natively.

2.  Clone the repository and go to the folder

    ```
    git clone https://github.com/Azure/azure-sdk-for-python.git
    cd azure-sdk-for-python
    ```

3.  Create a [virtual environment][virtual_environment]

    You can initialize a virtual environment this way:

    ```
    python -m venv env # Might be "python3" or "py -3.8" depending on your Python installation
    source env/bin/activate      # Linux shell (Bash, ZSH, etc.) only
    ./env/scripts/activate       # PowerShell only
    ./env/scripts/activate.bat   # Windows CMD only
    ```

4. Setup your development environment

    Install the development requirements for a specific library (located in the `dev_requirements.txt` file at the root of the library), [Tox][tox] and an editable install of your library. For example, to install requirements for `azure-ai-formrecognizer`:
    ```
    azure-sdk-for-python> cd sdk/formrecognizer/azure-ai-formrecognizer
    azure-sdk-for-python/sdk/formrecognizer/azure-ai-formrecognizer> pip install -r dev_requirements.txt
    azure-sdk-for-python/sdk/formrecognizer/azure-ai-formrecognizer> pip install "tox<5"
    azure-sdk-for-python/sdk/formrecognizer/azure-ai-formrecognizer> pip install -e .
    ```

5.  Create a .env file to store your secrets.

    The recommended place to store your .env file in the root of the SDK repository, as it will be gitignored.

## Follow test-running guidance

After following the steps above, you'll be able to run recorded SDK tests with `pytest`. For more information about tests -- how to run live tests, write new tests, etc. -- refer to the documentation in [tests.md][tests].
