"""Test GradientAI API wrapper.

In order to run this test, you need to have an GradientAI api key.
You can get it by registering for free at https://gradient.ai/.

You'll then need to set:
- `GRADIENT_ACCESS_TOKEN` environment variable to your api key.
- `GRADIENT_WORKSPACE_ID` environment variable to your workspace id.
- `GRADIENT_MODEL` environment variable to your workspace id.
