Basic Syntax #. To opt-in to the syntax, add the setup attribute to the <script> block: <script setup> ('hello script setup') </script>. The code inside is compiled as the content of the component's setup () function. This means that unlike normal <script>, which only executes once when the component is first imported, code inside. The.emitted () method returns the same object every time it is called, not a new one, and so the object will update when new events are fired: const emitted = wrapper.emitted() expect().toBe(1) // do something to make `wrapper` emit the "foo" event expect().toBe(2).
