 All tests run in the CI and must pass before merging.
 All tests run against a running langfuse instance and **write/delete real data from the database**.
 
+### Test Database Setup
+
+Per default, the tests use the local development database. Therefore, wiping your data in the process.
+For proper test isolation, create a `.env.test` file in the root directory:
+
+```bash
+cp .env.test.example .env.test
+```
+
+Then, a different PostgreSQL and Redis are used for the tests.
+The `.env.test` file only overrides the set values and falls back on `.env` for all undefined values.
+
+- **PostgreSQL**: Uses separate `langfuse_test` database for isolation
+- **ClickHouse**: Uses shared `default` database for now
+- **Redis**: Uses database 1 instead of 0 for isolation (Redis data is not cleaned between tests)
+
+Tests automatically create the PostgreSQL test database if it doesn't exist and clean up data between runs.

+We're using Jest with in the `web` package. Therefore, if you want to provide an argument to the test runner, do it directly without an intermittent `--`.
 
 There are three types of unit tests:
+
 - `test-sync`
 - `test-async`
 - `test-client`
 
 To run a specific test, for example the test: `"should handle special characters in prompt names"` in `prompts.v2.servertest.ts`, run:
+
 ```sh
 cd web  # or with --filter=web
 pnpm test-sync --testPathPattern="prompts\.v2\.servertest" --testNamePattern="should handle special characters in prompt names"
 ```
 
 To run all tests:
+
 ```sh
 pnpm run test
 ```
 
 Run interactively in watch mode (not recommended!)
+
 ```sh
 pnpm run test:watch
 ```
 
 ### Tests in the `worker` package

 For the `worker` package, we're using `vitest` to run unit tests.
