+### 4. (Optionally) Use PHPUnit:
+
+First, be sure the newest shippingdocker/php image has been build, you need it to use PHPUnit.
+
+Now just use the command as known:
+
+```bash
+docker run -it --rm \
+    -v $(pwd)/application:/opt \
+    -w /opt \
+    --network=phpapp_appnet \
+    shippingdocker/php \
+    phpunit
+```
+
