In my scenario, I have a created() hook that invokes the doSomething() method. To pass the tests, I currently override the methods parameter with jest.fn() in the shallowMount() function.
However, this approach triggers deprecation warnings related to the use of methods:
console.error
[vue-test-utils]: overwriting methods via the `methods` property is deprecated and will be removed in
the next major version. There is no clear migration path for the `methods` property - Vue does not
support arbitrary replacement of methods, nor should VTU. To stub a complex method, extract it from
the component and test it in isolation. Alternatively, consider revising those tests.
Here is a snippet from TestComponent.Vue:
...
created() {
doSomething();
}
...
methods: {
doSomething(): void { /* do something */ }
}
The testing script, TestComponent.test.ts, includes the following mounting method:
// mounting method used for tests
function genMount() {
const doSomething = jest.fn();
const el = document.createElement('div');
document.body.appendChild(el);
return shallowMount(TestComponent, {
localVue,
methods: { doSomething }, // deprecated param
store,
mocks,
attachTo: el,
stubs
});
}
Is there a way to mock the method triggered by the created() hook without relying on passing methods to shallowMount() in order to address the deprecation warnings?
Alternatively, is there a method to either mock or skip the created() lifecycle hook altogether?
Although importing the method and creating a mock for testing purposes is an option according to the warning suggestion, I am interested in exploring other solutions, particularly in cases where that would be excessive.
