 ## Testing
-- Test codes are located in [`/packages/backend/test`](/packages/backend/test).
-
-### Run test
-Create a config file.
+You can run non-backend tests by executing following commands:
+```sh
+pnpm --filter frontend test
+pnpm --filter misskey-js test
 ```
+
+Backend tests require manual preparation of servers. See the next section for more on this.
+
+### Backend
+There are three types of test codes for the backend:
+- Unit tests: [`/packages/backend/test/unit`](/packages/backend/test/unit)
+- Single-server E2E tests: [`/packages/backend/test/e2e`](/packages/backend/test/e2e)
+- Multiple-server E2E tests: [`/packages/backend/test-federation`](/packages/backend/test-federation)
+
+#### Running Unit Tests or Single-server E2E Tests
+1. Create a config file:
+```sh
 cp .github/misskey/test.yml .config/
 ```
-Prepare DB/Redis for testing.
-```
+
+2. Start DB and Redis servers for testing:
+```sh
 docker compose -f packages/backend/test/compose.yml up
 ```
-Alternatively, prepare an empty (data can be erased) DB and edit `.config/test.yml`.
+Instead, you can prepare an empty (data can be erased) DB and edit `.config/test.yml` appropriately.
 
-Run all test.
+3. Run all tests:

+pnpm --filter backend test:e2e # single-server E2E tests

-pnpm test
+If you want to run a specific test, run as a following command:

+## test-federation
+Test federation between two Misskey servers: `a.test` and `b.test`.
+
+Before testing, you need to build the entire project, and change working directory to here:
+```sh
+pnpm build
+cd packages/backend/test-federation
+```
+
+First, you need to start servers by executing following commands:
+```sh
+bash ./setup.sh
+docker compose up --scale tester=0
+```
+
+Then you can run all tests by a following command:
+```sh
+docker compose run --no-deps --rm tester
+```
+
+For testing a specific file, run a following command:
+```sh
+docker compose run --no-deps --rm tester -- pnpm -F backend test:fed packages/backend/test-federation/test/user.test.ts
+```
