             ### ✨ New Features
+            - **📁 Folder-Level Tests Support**: Tests defined at folder level in Postman collections are now automatically applied to all requests within that folder
+            - **🔄 Recursive Test Inheritance**: Support for nested folder hierarchies with test inheritance across multiple levels
             - **🛡️ Flexible Spec Validation**: New `--disable-spec-validation` flag to process specs with validation or reference issues
 
             ### 🎨 Enhanced Features
+            - **Better Coverage Calculation**: More accurate coverage metrics by including folder-level test assertions
+            - **Reduced Test Duplication**: Define common tests once at folder level instead of repeating on every request
+            - **Enterprise Collection Support**: Improved support for well-organized Postman collections with folder structures
             - **Legacy API Support**: Work with incomplete or invalid specs using `--disable-spec-validation`
 
+            ### 📁 Folder-Level Tests
+
+            Postman collections organized into folders can now have tests defined at the folder level that automatically apply to all child requests:
+
+            ```json
+            {
+              "name": "User API",
+              "item": [
+                { "name": "Get Users", "request": {...} },
+                { "name": "Create User", "request": {...} }
+              ],
+              "event": [{
+                "listen": "test",
+                "script": {
+                  "exec": ["pm.expect(pm.response.code).to.be.oneOf([200, 201]);"]
+                }
+              }]
+            }
+            ```
+
+            **Benefits:**
+            - ✅ Both requests inherit status codes 200 and 201 from folder
+            - ✅ Folder tests combine with request-level tests
+            - ✅ Supports unlimited nesting depth
+            - ✅ Backward compatible with existing collections

+### Folder-Level Tests in Postman Collections
+
+**swagger-coverage-cli** fully supports **folder-level tests** in Postman collections. Tests defined at the folder level are automatically applied to all requests within that folder and its subfolders, making it easy to apply common test assertions across multiple endpoints.
+
+#### How It Works
+
+When you define tests at the folder level in your Postman collection:
+1. The tests are extracted from the folder's event scripts
+2. Status codes and assertions are identified from the test scripts
+3. These tests are automatically combined with any request-level tests
+4. All requests within the folder (and nested folders) inherit these tests
+
+#### Example
+
+Consider this Postman collection structure:
+
+```json
+{
+  "name": "Users API",
+  "item": [
+    {
+      "name": "Get User",
+      "request": { "method": "GET", "url": "/users/1" }
+    },
+    {
+      "name": "Create User", 
+      "request": { "method": "POST", "url": "/users" }
+    }
+  ],
+  "event": [
+    {
+      "listen": "test",
+      "script": {
+        "exec": [
+          "pm.test('Status code is 200 or 201', function () {",
+          "    pm.expect(pm.response.code).to.be.oneOf([200, 201]);",
+          "});"
+        ]
+      }
+    }
+  ]
+}
+```
+
+In this example:
+- The folder "Users API" has a test that checks for status codes 200 or 201
+- **Both** "Get User" and "Create User" requests will inherit these status codes
+- This means both endpoints will be counted as testing status codes 200 and 201
+
+#### Benefits
+
+- **Reduced duplication**: Define common tests once at the folder level
+- **Better coverage**: Ensures all requests within a folder test common scenarios
+- **Easier maintenance**: Update folder-level tests to affect all child requests
+- **Nested support**: Folder-level tests are inherited through multiple levels of nesting
+
+#### Supported Test Patterns
+
+Folder-level tests support the same patterns as request-level tests:
+- `pm.response.to.have.status(200)`
+- `pm.expect(pm.response.code).to.eql(201)`
+- `pm.expect(pm.response.code).to.be.oneOf([200, 201, 204])`
+- And other common Postman test assertions
+
+#### Edge Cases Handled
+
+The folder-level test feature handles various edge cases:
+- **Empty folders**: Folders with no requests are handled gracefully
+- **Deep nesting**: Supports unlimited levels of nested folders with test inheritance at each level
+- **Missing events**: Requests or folders without event properties work correctly
+- **Mixed patterns**: Multiple test patterns in the same folder or request are combined
+- **Null/undefined events**: Folders with null or undefined event properties are handled safely
+- **Non-test events**: Only "test" events are processed; other events (like "prerequest") are ignored
+
 ### Using CSV for Documentation
 
 In addition to traditional OpenAPI/Swagger specifications, **swagger-coverage-cli** supports API documentation provided in a **CSV** format. This allows for a more flexible and easily editable documentation process, especially for teams that prefer spreadsheet-based documentation.
