Page Object

Simple sign-in page object for https://demo.atata.io/signin page:

using Atata;

namespace SampleApp.UITests
    using _ = SignInPage;

    [Url("signin")] // Relative URL of the page.
    [VerifyH1] // Verifies that H1 header text equals "Sign In" upon page object initialization.
    public class SignInPage : Page<_>
        [FindByLabel] // Finds <label> element containing "Email" (<label for="email">Email</label>), then finds text <input> element by "id" that equals label's "for" attribute value.
        public TextInput<_> Email { get; private set; }

        [FindById("password")] // Finds password <input> element by id that equals "password" (<input id="password" type="password">).
        public PasswordInput<_> Password { get; private set; }

        [FindByValue(TermCase.Title)] // Finds button element by value that equals "Sign In" (<input value="Sign In" type="submit">).
        public Button<_> SignIn { get; private set; }


Usage in the test method:

public void SignIn()
        .Email.Set("[email protected]")


public void SetUp()

Demo atata-framework/atata-sample-app-tests UI tests application demonstrates different testing approaches and features of Atata Framework. It covers main Atata features: page navigation, data input and verification, interaction with pop-ups and tables, logging, screenshot capture, etc.

Sample test:

public void User_Create()
    string firstName, lastName, email;
    Office office = Office.NewYork;
    Gender gender = Gender.Male;

            .ModalTitle.Should.Equal("New User")
            .General.FirstName.SetRandom(out firstName)
            .General.LastName.SetRandom(out lastName)
            .General.Email.SetRandom(out email)
        .Users.Rows[x => x.FirstName == firstName && x.LastName == lastName && x.Email == email && x.Office == office].View()
            .Header.Should.Equal($"{firstName} {lastName}")
