How i can get the unread mails using nightwatch js

Nightwatch.js is a Node.js based End-to-End (E2E) testing framework for web applications. To get the unread mails using Nightwatch.js, you'll need to use a combination of Nightwatch's built-in commands and some JavaScript code to interact with the email client or web application.

Here's a high-level example of how you can achieve this:

Assumptions:

You're using a web-based email client like Gmail, Outlook, or Yahoo Mail.
You have a Nightwatch.js test script set up to interact with the email client.

Step 1: Log in to the email client

Use Nightwatch's navigate command to navigate to the email client's login page, and then use the fill command to fill in the login credentials.

browser.url('https://example.com/login')
 .waitForElementVisible('input[name="username"]', 1000)
 .fill('input[name="username"]', 'your-username')
 .fill('input[name="password"]', 'your-password')
 .click('button[type="submit"]')
 .waitForElementVisible('div.email-list', 1000);

Step 2: Get the unread mail count

Use Nightwatch's execute command to execute a JavaScript function that retrieves the unread mail count from the email client's API or by parsing the HTML content of the email list page.

const unreadMailCount = browser.execute(function() {
  // Use a library like Cheerio or jQuery to parse the HTML content
  const $ = cheerio.load(browser.getHTML('div.email-list'));
  const unreadMails = $('div.email-list li.unread').length;
  return unreadMails;
});

Step 3: Verify the unread mail count

Use Nightwatch's assert command to verify that the unread mail count is greater than 0.

assert(unreadMailCount > 0, 'Expected unread mail count to be greater than 0');

Putting it all together

Here's the complete Nightwatch.js test script:

module.exports = {
  'Get unread mail count': function(client) {
    browser.url('https://example.com/login')
     .waitForElementVisible('input[name="username"]', 1000)
     .fill('input[name="username"]', 'your-username')
     .fill('input[name="password"]', 'your-password')
     .click('button[type="submit"]')
     .waitForElementVisible('div.email-list', 1000);

    const unreadMailCount = browser.execute(function() {
      const $ = cheerio.load(browser.getHTML('div.email-list'));
      const unreadMails = $('div.email-list li.unread').length;
      return unreadMails;
    });

    assert(unreadMailCount > 0, 'Expected unread mail count to be greater than 0');
  },
};

Note that this is just a basic example, and you'll need to modify the script to fit your specific use case. Additionally, you may need to use a library like Cheerio or jQuery to parse the HTML content of the email list page.
