Jest Testing onTouchStart/onTouchEnd - react-native

Question

I've got a component that uses the onTouchStart and onTouchEnd and I can't figure out how to test it.
Here's a snack for the code, but the snippet is below:
export default function TouchComponent({
children,
onStart = doNothing,
onEnd = doNothing
}: TouchComponentProps): React.ReactElement {
return (
<View
onTouchStart={(e) => onStart()}
onTouchEnd={(e) => onEnd()}
>{children}</View>
);
}
const doNothing = () => {};
interface TouchComponentProps {
children?: React.ReactNode;
onStart?: () => void;
onEnd?: () => void;
}
Looking at the documentation, there aren't any methods listed for onTouchStart/onTouchEnd, but this method array seems to suggest that it has other methods that can be invoked, but it doesn't look like it works here because fireEvent["onTouchStart"](myComponent); fails with an error saying: TypeError: _reactNative.fireEvent.onTouchStart is not a function.
I've searched around but can't seem to find any documentation or other questions about testing onTouchStart and onTouchEnd, so how do I fire these events?

Answer 1

I figured this out almost immediately after asking this question. In my situation, I can invoke them like this:
import TouchComponent from "../TouchComponent ";
import { render, fireEvent } from "#testing-library/react-native";
it("Invokes onTouchStart and onTouchEnd", () => {
const { getByTestId } = render(
<TouchComponent
onStart={() => {
console.log("onTouchStart invoked");
}}
onEnd={() => {
console.log("onTouchEnd invoked");
}}
testID="my-component" />);
const myComponent = getByTestId("my-component");
// Passing empty {} data, but may need to supply for other use cases.
fireEvent(myComponent, "onTouchStart", {});
fireEvent(myComponent, "onTouchEnd", {};
});
// Console:
// console.log
// onTouchStart invoked
// console.log
// onTouchEnd invoked
