Jest is not calling function correct number of times
0
I am mapping over an array and then calling an external function. example
['error1', 'error2'].map(err => myFunc())
then in my jest test I am saying, expect myFunc() to have been called 2 times
but it's saying it is only called once
it's an external function defined as such
export const myFunc = () => {}
then when I import im doing
import { myFunc } from 'file/path'
jest.mock('file/path', () => ({
myFunc: jest.fn(),
}))
expect(myFunc.mock.calls).toHaveLength(2)
anyone see what I'm doing wrong? really makes no sense as function should be called for every item in array :/
javascript reactjs jestjs

I'm just testing the array in the original code?

It’s a hard coded array with 2 entries?

oh no sorry I am mocking it with an array of 2 errors. and when I log it out, it's showing the array of length 2. but for some reason it's only showing one function even though the function should be called for every item in the array. so when I change to length 5, it's still only being called once :/

Hmm the issue is not obvious to me unfortunately. A live example on jsfiddle or similar might help.
