I cannot pass the test to dynamically change the value of the input tag when i clicked the button

My App Code

export function App() {
    const [inputValue, setInputValue] = React.useState("");
    const inputRef = React.useRef<HTMLInputElement>(null);

    const handleClick = (e: React.MouseEvent<HTMLButtonElement>) => {
        e.preventDefault();
        if (inputRef.current) {
            inputRef.current.value = inputRef.current.value + "1";
            setInputValue(inputRef.current.value);
        }
    };

    return (
        <form>
            <label htmlFor="password-input" >
                비밀번호
            </label>
            <input
                ref={inputRef}
                type="password"
                id="password-input"
                name="password-input"
                value={inputValue}
            />
            <button
                className="insert"
                data-testId={1}
                onClick={(e) => { handleClick(e) }}>
                입력
            </button>
        </form>)
}

My test code

test("Does clicking the button change the input value?", async () => {
        render(<App />);

        userEvent.click(await screen.findByTestId(1));
        userEvent.click(await screen.findByTestId(1));

        expect((await screen.findByLabelText<HTMLInputElement>(`비밀번호`)).value).toHaveLength(2);

        userEvent.click(await screen.findByTestId(1));
        userEvent.click(await screen.findByTestId(1));
        userEvent.click(await screen.findByTestId(1));
        userEvent.click(await screen.findByTestId(1));

        expect((await screen.findByLabelText<HTMLInputElement>(`비밀번호`)).value).toHaveLength(6);
    })

As a result of running the test code is

    expect(received).toHaveLength(expected)

    Expected length: 2
    Received length: 1
    Received string: "1"

      37 |         userEvent.click(await screen.findByTestId(1));
      38 |
    > 39 |         expect((await screen.findByLabelText<HTMLInputElement>(`비밀번호`)).value).toHaveLength(2);
         |                                                                                ^
      40 |
      41 |         userEvent.click(await screen.findByTestId(1));
      42 |         userEvent.click(await screen.findByTestId(1));

Every time I clicked on a button, i expected the input value to be "1", "11" and "111" from "", but it seems to work on dev server, but when i ran the test code, the input value continued to be less than the number of clicks. How can i fix thi error and pass the test?
Please help me...

• It should be data-testid, not data-testId.

• click() API returns a promise, so you need to use it like await useEvent.click().

• There is no need to use data-testid, you can find the button element by its accessible role('button') with accessible name('입력')

e.g.

index.tsx:

import React from 'react';

export function App() {
	const [inputValue, setInputValue] = React.useState('');
	const inputRef = React.useRef<HTMLInputElement>(null);

	const handleClick = (e: React.MouseEvent<HTMLButtonElement>) => {
		e.preventDefault();
		if (inputRef.current) {
			inputRef.current.value = inputRef.current.value + '1';
			setInputValue(inputRef.current.value);
		}
	};

	return (
		<form>
			<label htmlFor='password-input'>비밀번호</label>
			<input ref={inputRef} type='password' id='password-input' name='password-input' value={inputValue} />
			<button
				className='insert'
				onClick={(e) => {
					handleClick(e);
				}}
			>
				입력
			</button>
		</form>
	);
}

index.test.tsx:

import React from 'react';
import { render, screen } from '@testing-library/react';
import { App } from '.';
import userEvent from '@testing-library/user-event';

test('Does clicking the button change the input value?', async () => {
	render(<App />);

	const $button = screen.getByRole('button', { name: '입력' });

	await userEvent.click($button);
	await userEvent.click($button);

	let $passwordInput = (await screen.findByLabelText(`비밀번호`)) as HTMLInputElement;

	expect($passwordInput.value).toHaveLength(2);

	await userEvent.click($button);
	await userEvent.click($button);
	await userEvent.click($button);
	await userEvent.click($button);

	expect($passwordInput.value).toHaveLength(6);
	expect($passwordInput.value).toBe('111111');
});

Test result:

  console.error
    Warning: Failed prop type: You provided a `value` prop to a form field without an `onChange` handler. This will render a read-only field. If the field should be mutable use `defaultValue`. Otherwise, set either `onChange` or `readOnly`.
