Steps

1. Add a dependency to vitest pnpm add -D vitest
2. Add a dependency to @xwiki/platform-test-accessibility pnpm add -D @xwiki/platform-test-accessibility
3. Import the Vue component import MyComponent from "../MyComponent.vue"
4. Define a mount helper for the test suite using mountHelper const accessibilyMount = mountHelper(MyComponent);
5. Define the test suite

   import MyComponent from "../MyComponent.vue";
   import { mountHelper, runTest } from "@xwiki/platform-test-accessibility";
   import { describe } from "vitest";
   
   const accessibilyMount = mountHelper(MyComponent);
   
   describe("Test suite description", () => {
     runTest("test description", accessibilyMount(), () => {
       // Assertions ....
       // After this step, an axe-core validation is performed on the tested component.
       // Is is possible to call assertAxe during the test to assert the accessibility during intermediate states of the component
     });
   });
