 Feature: treesit expansions
   Background:
     Given there is no region selected
-    And I turn on rust-ts-mode
+    And rust-ts-mode is enabled
 
     Scenario: Successively expand the region
-    When I insert "fn some_func(arg: String) -> String { arg.to_lowercase() }"
-    And I place the cursor before "to_lowercase"
+    When I insert "fn foo() -> Option<()> {\n  let foo = Some(1)?;\n  None\n}"
+    And I place the cursor before "Some"
     And I press "C-@"
-    Then the region should be "to_lowercase"
+    Then the region should be "Some"
     And I press "C-@"
-    Then the region should be "arg.to_lowercase()"
+    Then the region should be "Some(1)"
     And I press "C-@"
-    Then the region should be "{ arg.to_lowercase() }"
+    Then the region should be "Some(1)?"
+    And I press "C-@"
+    Then the region should be "let foo = Some(1)?;"
