![]() ![]() ![]() How do we deal with email flows in Cypress tests?įor us to test out the entire email flows, we built out cy.task()plugins to: This should give you a better picture of what kind of functions to use and implement to handle these email flows, assuming you have a test email inbox server and your own credentials to connect to. We will not cover how to set up your own test email inbox server (like Squirrelmail), but we will focus on automating these steps related to searching for emails, parsing matching email contents, and following email links. You can still modify the code in your own Cypress tests by removing the type definitions and sticking to JavaScript-only syntax. Also, if the later code snippets with TypeScript are a bit confusing, it may clear things up to see our blog post about how we typed our Cypress tests. This post assumes you know some of the Cypress functions such as cy.task() to run arbitrary code we define in a Node server to assist us with dealing with emails. If you aren’t familiar with using Cypress for writing E2E tests in general, we strongly recommend you check out our one thousand foot overview about implementing Cypress tests for your web applications-this will give you a better idea of the Cypress API.If you have never written E2E tests before or would like a refresher about how to think when writing E2E tests, you may want to see this blog post before we start.Specifically, we would like to write E2E tests with Cypress, so we do not have to test these potentially slow and confusing email flows manually in our own web browser every time.īefore we get into the post, here are a couple of articles you may be interested in reading first. We can do this every time upon new code changes to ensure we did not regress anywhere, but it would be nice to automate these steps in an end-to-end (E2E) test we can run again whenever we want to. We test these features manually by inputting our Squirrelmail email addresses in the necessary forms, clicking some buttons, and following email links to validate things work as expected. Many important flows require the user to check their email, click on an actionable link, redirect back to the web application, and then continue onward at some download or verification success page. In our testing environments, we send our emails to test email inboxes in self-hosted Squirrelmail servers to avoid sending out test emails to actual email inbox service providers such as Gmail. We recently passed a huge milestone of over 3 trillion emails sent. To send all of our transactional emails-ranging from password reset to account email verification to export CSV emails-we use our own backend services. ![]()
