## Test plan

<!-- All pull requests REQUIRE a test plan:
https://docs-legacy.sourcegraph.com/dev/background-information/testing_principles
-->

For Enterprise instances using google as provider:

1. In your Soucegraph local instance's Site Config, add the following:

```
    "accessToken": "REDACTED",
    "chatModel": "gemini-1.5-pro-latest",
    "provider": "google",
```

Note: You can get the accessToken for Gemini API in 1Password.

2. After saving the site config with the above change, run the following
curl command:

```
curl 'https://sourcegraph.test:3443/.api/completions/stream' -i \
-X POST \
-H 'authorization: token $LOCAL_INSTANCE_TOKEN' \
--data-raw '{"messages":[{"speaker":"human","text":"Who are you?"}],"maxTokensToSample":30,"temperature":0,"stopSequences":[],"timeoutMs":5000,"stream":true,"model":"gemini-1.5-pro-latest"}'
```

3. Expected Output:

```
❯ curl 'https://sourcegraph.test:3443/.api/completions/stream' -i \
-X POST \
-H 'authorization: token <REDACTED>' \
--data-raw '{"messages":[{"speaker":"human","text":"Who are you?"}],"maxTokensToSample":30,"temperature":0,"stopSequences":[],"timeoutMs":5000,"stream":true,"model":"gemini-1.5-pro-latest"}'
