Automation is great, but how do you decide what to automate first ?

Test automation opens up real opportunities for QA teams: faster feedback, more consistent coverage, and the ability to focus energy where it truly matters. But achieving this depends less on the number of automated tests than on the choices made at the very beginning.

One thing comes up time and again: automation is first and foremost a prioritization challenge, long before it becomes a technical one.

Why automating everything doesn’t work ?

Automation comes with a cost that is often underestimated at the start. Every test that is written must be maintained, updated as the interface evolves, and analyzed when it fails unexpectedly.

When automation is done without selectivity, teams end up with endless test suites, failures that don’t reveal real issues, and more time spent fixing tests than detecting defects. Over time, trust erodes and automation loses its value. Giving it meaning from the outset is what makes it sustainable.

Start with business‑critical, high‑risk user flows

A good way to prioritize is to ask what would have an immediate and visible impact if it failed in production: user login, payments, data persistence, key integrations. These are the areas customers notice right away and where the risk is highest.

This is a natural starting point. Automating these flows quickly builds confidence in the stability of core features from one release to the next.

Let usage data and bug history guide you

Two simple indicators can help prioritize automation without overcomplicating things:

• how frequently a feature is used ;

• where defects tend to recur.

If users rely on a feature every day, even a minor bug can have a significant impact. Those flows deserve automation. And when something breaks across multiple versions, it’s rarely a coincidence. Defect history and support tickets are among the most valuable sources for planning automation, yet they are still too often overlooked.

Being selective is a strength, not a limitation

Before writing a test, it’s worth asking whether it will truly save time in the long run, whether the area is prone to breaking, and whether the feature is stable enough to be tested reliably. If the answer to most of these questions is no, postponing automation is often the better choice.

Choosing not to automate right away is just as valid as choosing to do so. Thinking in terms of impact and stability ensures automation creates value rather than technical debt.

Where QA judgment brings the most value

Quality Assurance plays a key role in shaping an automation strategy. Our QA teams understand user impact, risk areas, and where defects appear most often. This perspective helps teams focus their efforts where automation will truly make a difference.

Automation is not meant to replace manual testing, but to safeguard critical functionality so time can be freed up for exploration, usability improvements, and detecting issues that automation cannot catch.

In conclusion

When thoughtfully prioritized, automation becomes a genuine support for quality, not an extra layer of complexity to manage.
