I have this component that I am trying to test, that shows a dialog which accepts images to upload into the app:

I want mock the getConversionList being called in useEffect. However since new to mocking need help

I want to check if document.dispatchEvent is fired when we called sendEvent method. I also want to write negative test case like when we called sendEvent method, document.body.dispatchEvent should not fire. I need some help in writing testcase.

I am trying to simulate a simple click but at a specific position of the value of an input. For example if the value of the input is abcd, I want to click in the middle and leave caret between b and c.
