Feature File (Features/Login.feature)

Feature: User Login

  Scenario: Successful login
    Given I am on the login page
    When I enter "[email protected]" as email
    And I enter "password123" as password
    And I click the login button
    Then I should see the dashboard
    And the welcome message should contain "Welcome"

  Scenario: Invalid credentials
    Given I am on the login page
    When I enter "[email protected]" as email
    And I enter "wrong" as password
    And I click the login button
    Then I should see error "Invalid credentials"

  Scenario Outline: Login with various users
    Given I am on the login page
    When I enter "<email>" as email
    And I enter "<password>" as password
    And I click the login button
    Then I should see "<result>"

    Examples:
      | email          | password | result    |
      | [email protected] | admin123 | Dashboard |
      | [email protected]  | pass123  | Dashboard |
      | [email protected]   | wrong    | Error     |
