Atata Framework is a full-featured C#/.NET test automation framework built around a powerful context-driven architecture and session-based execution model. It provides an intuitive, fluent page object pattern for web UI testing, which remains its core capability, while Atata 4 expands beyond web UI automation into a universal, extensible testing ecosystem. Designed to minimize boilerplate, Atata enables clean, declarative test components using properties, attributes, and reusable building blocks. With customizable built-in logging, a unique event-driven trigger system, and a rich ecosystem of ready-to-use components, Atata provides a consistent foundation for building maintainable and scalable automated tests across different testing domains.
The package targets .NET 8.0 and .NET Framework 4.6.2.
- WebDriver. Provides Selenium WebDriver session functionality. Preserves all WebDriver capabilities for local, remote, and headless browser automation.
- Page object model. Provides a unique fluent page object pattern for concise, maintainable page and component definitions.
- Components. Includes a rich set of ready-to-use UI testing components for inputs, tables, lists, etc.
- Smart verification. Offers fluent assertions, aggregate checks, wait-aware verification, and built-in verification triggers.
- Triggers. Includes a set of triggers to bind with different events to extend component behavior.
- Configuration. Enables flexible settings, variables, URL templates, environment-aware run options, etc.
- Logging and reporting. Built-in customizable structured logging, screenshots, page snapshots, artifact generation, and extensible log consumer support.
- Extensible ecosystem. Features a bunch of add-ons such as Atata.HtmlValidation, Atata.NLog, Atata.AspNetCore, Atata.Testcontainers.
- Integration. Easily integrates with NUnit, xUnit, MSTest, Reqnroll via dedicated packages. Works flawlessly on CI systems like GitHub Actions, Jenkins, etc.
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.
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:
[Test]
public void SignIn()
{
Go.To<SignInPage>()
.Email.Set("[email protected]")
.Password.Set("abc123")
.SignIn.Click();

Sample test:
[Test]
public void Create() =>
Login()
.New()
.ModalTitle.Should.Be("New User")
.General.FirstName.SetRandom(out string firstName)
.General.LastName.SetRandom(out string lastName)
.General.Email.SetRandom(out string email)
.General.Office.SetRandom(out Office office)
.General.Gender.SetRandom(out Gender gender)
.Save()
.GetUserRow(email).View()
.AggregateAssert(x => x
.Header.Should.Be($"{firstName} {lastName}")
.Email.Should.Be(email)
.Office.Should.Be(office)
.Gender.Should.Be(gender)
