+Feature: Formatting
+
+  Scenario: Changing formatter
+    Given I have maven project "m" in "tmp"
+    And I have a java file "tmp/m/src/main/java/temp/App.java"
+    And I add project "m" folder "tmp" to the list of workspace folders
+    And I clear the buffer
+    And I insert:
+    """
+    package temp; import java.util.ArrayList; class App {ArrayList<String> al = new ArrayList<>();}
+    """
+    And I call "save-buffer"
+    And I use formatter profile "profileName" from "testFormatter.xml"
+    And I start lsp-java
+    And The server status must become "LSP::Started"
+    When I indent buffer
+    And I call "save-buffer"
+    Then I should see:
+    """
+    package temp;
+    import java.util.ArrayList;
+    class App
+    {
+    	ArrayList<String> al = new ArrayList<>();
+    }
+    """
