I'm news with tests, se, here is my problem
I have that simple login component:
import React, { useState } from "react";
export default function Login() {
const [email, setEmail] = useState("");
const [password, setPassword] = useState("");
function handleLogin(event) {
event.preventDefault();
console.log(email, password);
}
return (
<form data-testid="login-form" onSubmit={handleLogin}>
<input
data-testid="useremail"
type="email"
placeholder="Email"
value={email}
onChange={event => setEmail(event.target.value)}
/>
<input
data-testid="userpassword"
type="password"
placeholder="Password"
value={password}
onChange={event => setPassword(event.target.value)}
/>
<button onClick={handleLogin}>login</button>
</form>
);
}
I here my test attempty:
import React from "react";
import Login from "../pages/Login";
import { render, fireEvent } from "@testing-library/react";
describe("Login component", () => {
it("user sent email and password", () => {
const username = "user@gmail.com";
const password = "123456";
let { getByText, getByTestId } = render(<Login />);
fireEvent.change(getByTestId("useremail"), {
target: { value: username }
});
fireEvent.change(getByTestId("userpassword"), {
target: { value: password }
});
fireEvent.submit(getByTestId("login-form"));
expect(getByTestId("login-form")).toContainElement(
getByText(username, password)
);
});
});
the error that returns: Unable to find an element with the text: user@gmail.com. This could be because the text is broken up by multiple elements. In this case, you can provide a function for your text matcher to make your matcher more flexible.
