The Whole Journey, Verified

End-to-end testing

Your users don't experience your app one component at a time. Test the complete journey, from the UI they see to the emails, files, APIs, and databases working behind it.

The Basics

What is modern end-to-end testing?

Modern applications lean on third party plugins, dynamic content, and embedded services. Maybe your site uses an interactive map. Maybe it pulls a newsfeed from a partner, or embeds a syndicated webshop. Proving all of it works is vital.

End-to-end (e2e) testing means testing the complete functionality that touches the end user, not just the parts you built yourself.

Three Layers, One Test

What e2e testing has to cover

A real end-to-end test verifies three things at once.

Content in the UI

Confirm that everything displays correctly in the interface, including embedded and third party content.

User-facing behavior

Validate the functionality exactly as a user experiences it, from clicks to confirmations.

Behind the scenes

Check what happens in the backend or in the third party service the flow depends on.

Why It Matters

Why is modern e2e testing so critical?

Embedded content and plugins let every team offer rich, satisfying experiences without custom coding every element of a site. That is great news, with one catch.

Users keep getting savvier and less forgiving of errors, while exhaustive manual testing is slow to the point of impossible. Worse, many automation frameworks simply cannot see embedded content at all, which pushes teams straight back to manual checks.

How Functionize Helps

The complete AI-powered e2e solution

Functionize takes a different approach to e2e testing. Rather than driving native desktop applications and installing software on every test machine, we brought the most common e2e scenarios into the cloud.

A suite of web-based tools lets you test not only your application's UI and UX, but also databases, Excel sheets, PDF files, APIs, text messages, emails, and plenty more.

MFA Without the Pain

Testing multi factor authentication

MFA improves security and complicates testing. Functionize makes the whole flow straightforward.

Assign an inbox

Use a working email or mobile number. Functionize Studio creates these randomized values automatically and re-randomizes them for every run.

Grab the message

During the login flow, open the email or SMS from the matching inbox.

Extract the code

Use the simple filter function to pull out the verification code and assign it to a variable.

Log in

Enter the code and continue through the authenticated flow.
APIs Included

Comprehensive API testing

The built-in API Explorer lets your tests inspect and interact with APIs directly, which is especially handy when third party content is involved.
  • Save API responses, such as API keys, as variables and reuse them across your test.
  • Works with basic authentication, OAuth 2, and proxy authentication.
  • A clean UI makes it quick to build custom requests and inspect the responses.

Exports, Verified

Testing file exports

Plenty of web applications generate files that users download or export, from ticket booking sites to online tax calculators. The File Viewer lets you verify those files as part of your test.

  • Supports the most common file types, including PDF, HTML, and Excel.
  • Validates the exported file's contents against the data in your web application.
  • Lets you assemble complex end-to-end tests in minutes.

Down to the Data

Database testing and Extensions

Connect to multiple database types and execute queries mid-test. Verify the contents directly, or store the results to use later in the flow.

Need to go further? Extensions let you power up the platform with reusable code snippets: run mid-flight actions like fetching a valid order number from an external system, host internal libraries in NodeJS, Python, or Go, or trigger externally hosted APIs, such as submitting an order from a POS machine or managing credentials on your own infrastructure.
