Core Patterns

Feature File (Gherkin)

Feature: User Login
  As a registered user
  I want to log into the application
  So that I can access my dashboard

  Background:
    Given I am on the login page

  Scenario: Successful login
    When I enter "[email protected]" in the email field
    And I enter "password123" in the password field
    And I click the login button
    Then I should be redirected to the dashboard
    And I should see "Welcome" on the page

  Scenario: Invalid credentials
    When I enter "[email protected]" in the email field
    And I enter "wrongpass" in the password field
    And I click the login button
    Then I should see an error message "Invalid credentials"

  Scenario Outline: Login with various users
    When I enter "<email>" in the email field
    And I enter "<password>" in the password field
    And I click the login button
    Then I should see "<result>"

    Examples:
      | email           | password    | result     |
      | [email protected]  | admin123    | Dashboard  |
      | [email protected]   | password    | Dashboard  |
      | [email protected]    | wrong       | Error      |
