testing input events with react testing library - react-testing-library

Question

I've created a small keypad app in react and I'm trying to test the input event on the app and for some reason I am not getting the expected result. I'm trying to test it to failure and success. The test I'm running is this below, I want to input 1995 (the correct combination), click the unlock button and ultimately have a message return Unlocked! but it only returns Incorrect Code! which should only happen if the code is incorrect or the input field is empty. But it shouldn't be empty as I have filled it out in the test..
here is a codesandbox: https://codesandbox.io/s/quirky-cloud-gywu6?file=/src/App.test.js:0-26
Any ideas?
test:
const setup = () => {
const utils = render(<App />);
const input = utils.getByLabelText("input-code");
return {
input,
...utils
};
};
test("It should return a successful try", async () => {
const { input, getByTestId } = setup();
await act(async () => {
fireEvent.change(input, { target: { value: "1995" } });
});
expect(input.value).toBe("1995");
await act(async () => {
fireEvent.click(getByTestId("unlockbutton"));
});
expect(getByTestId("status")).toHaveTextContent("Unlocked!");
});
the component I'm trying to test
import React, { useState, useEffect } from "react";
import Keypad from "./components/Keypad";
import "./App.css";
import "./css/Result.css";
function App() {
//correctCombination: 1995
const [result, setResult] = useState("");
const [locked, setLocked] = useState("Locked");
const [tries, setTries] = useState(0);
const [hide, setHide] = useState(true);
//Along with the maxLength property on the input,
// this is also needed for the keypad
useEffect(() => {
(function() {
if (result >= 4) {
setResult(result.slice(0, 4));
}
})();
}, [result]);
const onClick = button => {
switch (button) {
case "unlock":
checkCode();
break;
case "clear":
clear();
break;
case "backspace":
backspace();
break;
default:
setResult(result + button);
break;
}
};
const checkCode = () => {
if (result === "1995") {
setLocked("Unlocked!");
setTries(0);
} else if (tries === 3) {
setHide(false);
setLocked("Too many incorrect attempts!");
setTimeout(() => {
setHide(true);
}, 3000);
} else {
setLocked("Incorrect code!");
setTries(tries + 1);
}
};
const clear = () => {
setResult("");
};
const backspace = () => {
setResult(result.slice(0, -1));
};
const handleChange = event => {
setResult(event.target.value);
};
return (
<div className="App">
<div className="pin-body">
<h1>Pin Pad</h1>
<div className="status">
<h2 data-testid="status">{locked}</h2>
</div>
<div className="result">
<input
maxLength={4}
type="phone"
aria-label="input-code"
data-testid="inputcode"
placeholder="Enter code"
onChange={handleChange}
value={result}
/>
</div>
{hide ? <Keypad onClick={onClick} /> : false}
</div>
</div>
);
}
export default App;
