+# Scoping Testing
+
+Scoping tests are data-driven instead of being specified explicitly. This document explains how to add a new scoping
+test.
+
+## Adding a scoping test
+
+1. Create a new **folder** (not just a file!) in the `DSL/tests/resources/scoping` directory or any
+   subdirectory. Give the folder a descriptive name, since the folder name becomes part of the test name.
+
+    !!! tip "Skipping a test"
+
+        If you want to skip a test, add the prefix `skip-` to the folder name.
+
+2. Add files with the extension `.sdstest` **directly inside
+   the folder**. All files in a folder will be loaded into the same workspace, so they can
+   reference each other. Files in different folders are loaded into different workspaces, so they cannot reference each other.
+3. Add the Safe-DS code that you want to test to the file.
+4. Surround **the name** of any declaration that you want to reference with test markers, e.g. `class »C«`. Add a
+   comment in the preceding line with the following format (replace `<id>` with some unique identifier):
+    ```ts
+    // $TEST$ target <id>
+    ```
+5. Surround references you want to test with test markers, e.g. `»C«()`. If you want to assert that the reference should be resolved,
+   add a comment in the preceding line with the following format (replace `<target_id>` with the identifier you previously
+   assigned to the referenced declaration):
+
+    ```ts
+    // $TEST$ references <target_id>
+    ```
+   If you instead want to assert that the reference is unresolved, add the following comment to the preceding line:
+    ```ts
+    // $TEST$ unresolved
+    ```
+6. Run the tests. The test runner will automatically pick up the new test.
