As a best practice, we recommend setting your Sauce Labs authentication credentials as environment variables on your local system, that can then be referenced from within your tests. This provides an extra layer of security for your tests, and also enables other members of your development and testing team to write tests that will authenticate against a single account. 

Finding Your Username and Access Key

You can find your Sauce Labs username and access key in the User Profile > User Settings section of your Sauce Labs dashboard.


Setting Up Environment Variables on Mac OSX/Linux Systems

  1. In Terminal mode, enter vi ~/.bash_profile, and then press Enter.

  3. Enter these lines:

    export SAUCE_USERNAME="your Sauce username"
    export SAUCE_ACCESS_KEY="your sauce access key"
  4. Press Escape.
  5. Hold Shift and press Z twice (z z) to save your file and quit vi.

  6. In the terminal, enter source ~/.bash_profile.

Setting Up Environment Variables on Windows Systems

  4. Click Environment Variables.
    This will open the Environment Variables dialog.
  5. In the User variables section, click New.
    This will open the New System Variable dialog.
  6. For Variable name, enter SAUCE_USERNAME.
  7. For Variable value, enter your Sauce username.
  8. Click OK.
  9. Repeat 4 - 8 to set up the SAUCE_ACCESS_KEY.

Referencing Environment Variables in Test Scripts

Once you've set up the environment variables for your credentials, you need to reference them within the test scripts that you want to run on Sauce. You can find examples of test scripts that use environment variables for authentication in the demo directory for each language in the Sauce Labs Training repo on GitHub. This example is for C#.
