Automated Tests Do Not Work With New `mailpit` Email For Locals

by ADMIN 64 views

Introduction

Automated tests are an essential part of any software development process. They help ensure that the application works as expected, catch bugs early, and provide a safety net for changes made to the codebase. However, when it comes to testing email functionality, things can get complicated. In this article, we will discuss the issue of automated tests not working with the new mailpit email for locals and how to resolve it.

Understanding the Issue

The new mailpit email for locals is a feature provided by Supabase, a popular open-source backend platform. It allows developers to interact with fake emails sent by Supabase's local environment. However, this new API has caused issues with automated tests that rely on playwright-tests, a popular testing framework for web applications.

What is mailpit and Why is it Important?

mailpit is a new API provided by Supabase that allows developers to interact with fake emails sent by Supabase's local environment. This API is essential for testing email functionality in applications that use Supabase as their backend. With mailpit, developers can now easily test email sending and receiving functionality without having to set up a real email account.

The Problem with Automated Tests

Automated tests that rely on playwright-tests are not working with the new mailpit email for locals. This is because playwright-tests uses a different approach to interact with emails than the new mailpit API. As a result, tests that were working fine before the introduction of mailpit are now failing.

Resolving the Issue

To resolve this issue, we need to update our automated tests to use the new mailpit API. Here are the steps we can follow:

Step 1: Update playwright-tests to Use the New mailpit API

We need to update our playwright-tests configuration to use the new mailpit API. This involves changing the email provider from the default one to mailpit.

// playwright.config.js
module.exports = {
  // ... other configurations ...
  email: {
    provider: 'mailpit',
  },
};

Step 2: Update Test Code to Use the New mailpit API

We need to update our test code to use the new mailpit API. This involves changing the way we interact with emails to use the mailpit API.

// test.js
import { test, expect } from '@playwright/test';

test('email test', async ({ page }) => {
  // ... other test code ...
  const email = await page.waitForSelector('.email');
  const emailContent = await email.textContent();
  expect(emailContent).toContain('Hello, world!');
});

Step 3: Verify That Tests Are Working as Expected

After updating our playwright-tests configuration and test code, we need to verify that tests are working as expected. This involves running our tests and checking that they pass without any issues.

Conclusion

In conclusion, automated tests do not work with the new mailpit email for locals due to changes in the wright-tests configuration and test code. However, by updating our playwright-tests configuration and test code to use the new mailpit API, we can resolve this issue and ensure that our automated tests continue to work as expected.

Best Practices for Testing Email Functionality

When testing email functionality, it's essential to follow best practices to ensure that our tests are reliable and accurate. Here are some best practices to keep in mind:

Use a Real Email Account

When testing email functionality, it's essential to use a real email account. This ensures that our tests are accurate and reliable.

Use a Fake Email Account

However, using a real email account can be time-consuming and may require additional setup. In such cases, we can use a fake email account provided by Supabase's local environment.

Use the New mailpit API

The new mailpit API provides a convenient way to interact with fake emails sent by Supabase's local environment. We should use this API to update our automated tests.

Verify That Tests Are Working as Expected

After updating our automated tests, we need to verify that they are working as expected. This involves running our tests and checking that they pass without any issues.

Common Issues with Automated Tests

When testing email functionality, we may encounter common issues with automated tests. Here are some common issues to keep in mind:

Tests Are Failing Due to Email Provider Changes

When we update our email provider to use the new mailpit API, our tests may fail due to changes in the email provider.

Tests Are Failing Due to Changes in Email Content

When we update our email content to use the new mailpit API, our tests may fail due to changes in the email content.

Tests Are Failing Due to Changes in Email Sending and Receiving

When we update our email sending and receiving functionality to use the new mailpit API, our tests may fail due to changes in the email sending and receiving functionality.
