Answer 1

It seems you need to set up the saucelab environment variables.

1. Click Start on the taskbar.

2. For Search programs and fields, enter Environment Variables.

3. Click Edit the environment variables. This will open the System Properties dialog.

4. Click Environment Variables. This will open the Environment Variables dialog.

5. In the System 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.
