I encountered a PrimeVue error while running a Vue Jest test

When working on a Vue jest test, I encountered an error message "No PrimeVue Confirmation provided!" which seemed to be related to the useToast() and useConfirm() services.

"transformIgnorePatterns": [
      "<rootDir>/node_modules/(?!primevue/.*)"
    ]

I added this code snippet while configuring jest and the final version looked like this:

   "jest": {
    "preset": "@vue/cli-plugin-unit-jest",
    "transform": {
      "^.+\\.vue$": "vue-jest"
    },
    "transformIgnorePatterns": [
      "<rootDir>/node_modules/(?!primevue/.*)"
    ]
  }

However, the errors persisted even after making these changes.

To address the issue, I globally imported PrimeVue in the .spec.js file where my test was located.

import PrimeVue from "primevue/config";

  const wrapper = mount(VehicleInfo, {
      global:{
        plugins: [PrimeVue]
      },
      props: { nationCode:1 }
    })

The specific error occurred at this part of the code:

   No PrimeVue Confirmation provided!

      66 |     })
    > 67 |     const confirm = useConfirm()
         |                     ^
      68 |     const toast=useToast()

Answer №1

Here is a solution that worked well for me:

import { useConfirm } from 'primevue/useconfirm';
import PrimeVue from 'primevue/config';
import ConfirmationService from 'primevue/confirmationservice';

const componentWrapper = shallowMount(MyComponent, {
  props: { aProp },
  global: {
    components: { useConfirm },
    plugins: [PrimeVue, ConfirmationService],
  },
});
