📚 Description

Problem

The setupImportMocking function was failing when presets contained string values (e.g., vitest) instead of objects with an imports property.

export default defineNuxtConfig({
  imports: { presets: ["vitest"] },
})

This caused a TypeError when trying to access p.imports on string presets, breaking test execution.

⎯⎯⎯⎯ Startup Error ⎯⎯⎯⎯
TypeError: Cannot read properties of undefined (reading 'includes')

Solution

Added optional chaining (?.) to safely check if the imports property exists before calling .includes('setInterval'). This prevents errors when presets are strings rather than objects with an imports array.
