When I run the test, I get 'Error: No such validator'required' exists.', How can I fix it?

[Vivi-Ornitier]

I'm using vee-validate in my page.

When I load that page with mount for @vue/test-utils, I get Error: No such validator ‘required’ exists. .

I don't know how to solve this problem.
Can you tell me how to solve it?

Did you call defineRule before running the test? usually if you use global rules you will need to define them or register them before running your tests. beforeAll sounds a reasonable place to do that.
