Admin UI e2e (Playwright)

A standalone Playwright suite that drives the LiteLLM Admin UI in a real browser, separate from the Python harness in the sibling folders. It proves the flows a proxy admin actually clicks through, and cross-checks each one against the proxy API so a green test means the browser action really took effect on the server

The single spec here logs in as the proxy admin, creates a virtual key scoped to one model through the create-key modal, and then asserts both halves of the contract: /key/info reflects the alias and model the form set (the write persisted), and the generated key serves /chat/completions on its scoped model while being denied key_model_access_denied on a model outside that scope (the gateway enforces the scope)

Prerequisites

You need a running proxy that serves the UI on http://localhost:4000 (the repo's tests/e2e/docker-compose.yml brings one up with the gemini-2.5-flash and gpt-5.5 models this spec uses). The admin credentials are username admin and password = the proxy master key

Running

1. Install dependencies and the browser from this folder:

   npm install
   npm run install:browser
   

2. Bring up a proxy (from tests/e2e/):

   docker compose up -d
   curl -fs http://localhost:4000/health/liveliness
   

3. Run the suite:

   npm test
   

Configuration

The base URL and credentials come from the environment so the same spec runs against localhost or a deployed proxy

• LITELLM_PROXY_URL (default http://localhost:4000)
• LITELLM_MASTER_KEY (default sk-1234)
• E2E_UI_ALLOWED_MODEL (default gemini-2.5-flash), the model the key is scoped to
• E2E_UI_DENIED_MODEL (default gpt-5.5), a model outside the scope used to assert the denial
