Why You Should Automate End-to-End tests

End-to-end testing is essential to risk reduction. However many cite high costs as a reason to focus on other testing forms. The key to solving this lies in automation. Read more about why you should automate end-to-end tests in this article.

Digital transformation of businesses is not only necessary, but it is also happening. One of the effects this has is that many business-related operations are dependent on an ever-increasing number of platforms, systems, and applications.

Many business models also incorporate client facing software. In fact, we don’t have to look much further than online banking or shopping to find everyday services that incorporate a workflow and information processing.

In online banking, for instance, it is essential that the information a customer types into the online bank system when they make payments is updated in the the internal systems the bank relies on. A blatant example, but if this doesn’t work it can result in a negative impact on revenue.

What is end-to-end testing?

From a tester’s perspective, these transactions translate into workflows, where the success of a test is dependent on all the smaller pieces of code that make up an application and ensure that it is working properly.

One method of testing that ensures that the functionality works as it should is end- to-end to testing.

This type of test is performed via the user interface (UI) by testers, not programmers, and differs from unit and integration tests. These are performed by developers checking their own code.

If we think of a workflow in the software application like a car, then unit tests are like tests of smaller components that make up the motor or gearbox.

In this analogy, the end-to-end tests focus on how the car works when someone gets in the car, turns the key and drives. Set in this context, we all know that both are important, but the difference lies in what the tests can determine.

Even if we test that all the components in a car work individually, we aren't guaranteed that they will work altogether, which is why end-to-end testing is so important.

Now the purpose of this article is not to disregard unit or integration tests. However, the value of working units of code become less when they don’t work together from the user’s perspective.

The product must work for the user (customer), or we risk losing them as a customer. In this way, end-to-end tests are an invaluable way of checking a workflow in its entirety.

Key Benefits of End-to-End Testing

Another way of talking about this form of testing is in relation to the value that it creates.

The value gained lies in making sure a flow works as intended from the perspective of the user, and in ensuring that it fulfills business objectives.

Overall when talking about the value of end-to-end testing for a business, the benefits can be boiled down to some key points.

End-to-end testing:

  • ensures complete correctness and health of application entirety
  • ensures that functionality is optimized for customer experiences
  • exercises the logic your business flows
  • exercises all the tiny pieces of code working together
  • tests many things working together in a flow
  • reduces future risks

However, as with most things, there are objections to this form of testing. The main reasons being that end-to-end testing is slow and time-consuming.

The solution to this is automation. 

However, if the wrong type of automation tool is chosen, automation can also end up taking much time and resources.

That's why no-code automation is ideal for end-to-end automation.

Why automate end-to-end testing with a no-code test automation tool?

There are a number of low-code automation tools on the market that aim to resolve the issue of time, by removing some of the programming required to set up automation.

However, to achieve truly agile development, no-code automation is a must, as it takes significantly less time to set up and maintain.
