Ensuring that dependencies are properly mocked/stubbed is crucial. One of the first challenges you might encounter is mocking the HTTP service, as your tests may fail without an active Internet connection to the backend server. Consider exploring dependency injection as a solution.
When testing actions, I found inspiration in Vuex's recommendations. It involves creating a stub for the commit function that can verify the type and payload of each mutation called by the action, comparing it with the expected outcomes. If the list of mutations triggered by the commit stub matches those anticipated when the action executes, then the test is successful.
While this example is simplistic and not intended for production use, it serves as a demonstration:
let count = 0
let errors = []
let mutations = [
{ type: 'SET_USER', payload: 'expected response.data value' }
]
function commit(type, payload) {
const mutation = mutations[count]
try {
expect(mutation.type).to.equal(type)
if (payload) { expect(mutation.payload).to.deep.equal(payload) }
} catch (error) {
errors.push(error)
}
count++
}
actions.loginUser({ commit }, { email: '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="5a3c3b313f1a3f373b333674393537">[email protected]</a>', password: '12345' })
