End-to-End Testing: The Complete Journey, All the Way to the Back Office

A customer places an order, the order is processed in the ERP system, inventory is adjusted, and a confirmation email is sent. The end-to-end test verifies the entire process, including systems you didn't develop.

Sequencing Scenarios in " Mr Suricate ": Two Linked Paths Planned Each Day

They trust us

Retail, banking, manufacturing, transportation, and services: Our clients run nearly 3 million scenario simulations per month on their critical workflows.

Every brick works, and yet the chain breaks

The website works, the ERP system works, and the payment provider works. The problem lies at the interface: a renamed field, a changed date format, or a webhook that’s no longer being received. This issue doesn’t belong to any single team, and no unit test catches it, because it exists only where the systems communicate with each other.

From the Screen to the Management System

The script doesn't stop at the confirmation page. It verifies that the order has indeed arrived at its intended destination.

Systems You Don't Develop

ERP, CRM, payment providers, shipping carriers. Their updates disrupt your user experience, and no one warns you about it.

Email and the document as steps

Receiving a confirmation email, the content of a document, a webhook response. These are steps in the user journey, and therefore steps in the test.

One campaign, multiple interfaces

Web, mobile, and APIs in the same scenario—because the actual user journey moves seamlessly between them without the user even noticing.

Integrates with your pipeline without rewriting it

Your end-to-end workflows are triggered from your CI, run in your production environments, and feed back into where your teams are already working. No retooling required.

Unit Tests

With an end-to-end test

Each team tests its own scope.

The course is tested from start to finish.

A joint failure belongs to no one.

It is assigned to a specific stage.

A service provider's update goes unnoticed.

The plan fails that very day.

The back office is checked manually from time to time.

It is checked every time it runs.

It takes half a day to reproduce the problem.

The capture and the check are already in place.

We test what we know how to do.

We test what the customer experiences.

ResultThe entire supply chain is verified with every delivery, including third-party systems over which you have no control.

“Before we started using Mr Suricate’s tools, it took us an entire day to retest all the site’s features after a new version was released. Now, it only takes 10 minutes. In just 10 minutes, with about 40 critical test scenarios in pre-production, we know whether everything is OK or not. For us, that’s the best selling point: the time savings.”

YOUR QUESTIONS

Frequently Asked Questions

The most common questions we get about end-to-end testing.

What is the difference between functional testing and end-to-end testing?

A functional test validates a feature within its scope: the shopping cart calculates the correct total. An end-to-end test tracks the user journey beyond the interface, all the way to the systems that receive the data. It’s a matter of scope, not technique.

Can we test a back-office system or an ERP?

Yes, as long as it is accessible via a browser or an API. The script connects to the back office just as an administrator would and verifies that the order, inventory, or customer file are in the expected state.

How do you verify that an email has been received?

Receiving an email becomes a step in the flow, with the ability to control its content. This is useful for order confirmations, activation links, and one-time passwords, which often block the user from continuing through the process.

Aren't end-to-end tests too fragile?

That's their reputation, and it stems from maintenance. The more systems a scenario passes through, the more changes it encounters. Self-healing fixes some of the issues, and reusable blocks prevent the need to correct the same step in fifteen scenarios.

Are dedicated environments necessary?

Not necessarily, but you need dedicated data. A workflow that generates an actual order in a production ERP system must rely on accounts and part numbers set aside for testing. This is the key point to clarify before getting started, even more so than the environment itself.

What distinguishes an end-to-end test from a functional test?

The scope. A functional test validates a screen or an action. An end-to-end test runs through the entire chain—often spanning multiple applications and systems—until final confirmation. That’s where the failures that no one sees coming lie.

How do you link multiple scenarios together?

Through sequencing: you arrange the scenarios in order; they run sequentially and pass variables to one another. The sequence is planned as a single scenario, and its overall status is tracked in one place.

What happens if an intermediate step fails?

The flow stops or continues depending on the severity level specified for the action group. A group marked as "blocking" interrupts the flow, which prevents the flow from proceeding in an inconsistent state and avoids a cascade of false failures.

Can you pass through multiple environments on a single route?

Yes. Environment management allows you to override data and URLs at launch, so the same sequence can be replayed in the test environment and then in the production environment without being duplicated.

Do you only believe what you see?
