Cucumber/Automation测试:如何使用javascript函数实现整体概念？

Feature: Login Feature
  As a user
  I want to log in to the website
  So that I can access my account

  Scenario: Successful login
    Given I am on the login page
    When I enter valid credentials
    And click on the login button
    Then I should be redirected to the dashboard page
    And see a welcome message

  Scenario: Invalid login
    Given I am on the login page
    When I enter invalid credentials
    And click on the login button
    Then I should see an error message

const { Given, When, Then } = require('cucumber');
const { expect } = require('chai');

Given('I am on the login page', function () {
  // Navigate to the login page
});

When('I enter valid credentials', function () {
  // Enter valid username and password
});

When('click on the login button', function () {
  // Click on the login button
});

Then('I should be redirected to the dashboard page', function () {
  // Assert the current URL is the dashboard page
});

Then('see a welcome message', function () {
  // Assert the presence of a welcome message
});

When('I enter invalid credentials', function () {
  // Enter invalid username and password
});

Then('I should see an error message', function () {
  // Assert the presence of an error message
});
