-        service: [{
+```typescript
+import externalService from './externalService';
+
+export default {
+    service: [
+        {
+            options: {
+                data: 42
+            },
+            before() {
+                console.log(this.options.data);
+            },
             after(result) {
                 if (!result.success) process.exitCode = 1;
             }
-        }]
-    }
+        },
+        {

+            },
+            ...externalService
+        }
+    ]
 }

 There is a one minute-long default timeout for a before and after test logic to prevent entire process from freezing.
 To set up a custom timeout in milliseconds use serviceTimeout property in the config file
-```javascript
-module.exports = {
-    default: {
-        serviceTimeout: 1_200_000
-    }
+```typescript
+export default {
+    serviceTimeout: 1_200_000
 }
 ```
