API Testing

TestFly supports pure API tests and hybrid UI + API tests out of the box — same framework, same config, same report.

Pure API Tests — BaseApiTest

Extend BaseApiTest instead of BaseTest. No browser is launched; the full framework lifecycle still applies (reporting, @TestData, retry, CI gates).

import io.testfly.test.BaseApiTest;
import io.testfly.client.ApiClient;
import io.testfly.client.ApiResponse;
import org.testng.annotations.Test;

public class UserApiTest extends BaseApiTest {

    @Test
    public void getUserById() {
        ApiResponse res = ApiClient.get("https://api.example.com/users/1")
                .send();

        res.assertStatus(200);
        res.assertJson("$.name", "John Doe");
    }
}
