Which test scenarios should you automate first?
The first automated tests should not simply be the easiest ones to write. They should protect processes that matter to customers while saving the team repeated work. The right order therefore combines business risk, technical suitability, and the cost of long-term maintenance.
Why the number of tests alone is not enough
A team can quickly create dozens of checks for the footer, simple forms, or static content. The report looks good, but a failure in sign-in, ordering, or payment remains uncovered. The investment grows without reducing the greatest risk.
Trying to automate the entire product at once creates the opposite problem. Some features change so frequently that their tests need constant rewriting, while others are used only rarely. Without priorities, maintenance can consume more time than automation saves.
How to set the order: five practical criteria
Ask the same questions about every candidate scenario:
- Impact: what happens to the customer and the business if the process does not work?
- Frequency: how often do customers use the process, and how often does the team check it?
- Change risk: how often does the relevant code change, and how many systems does the process connect?
- Work saved: how much time does the repeatable manual check take?
- Maintenance effort: can the data be prepared and the result verified unambiguously?
A scenario with high impact, frequent use, and a clear result is a good candidate for the first wave. A very risky scenario with expensive data preparation may still be important, but it first needs technical preparation.
What usually comes first
In an online store, common candidates include sign-in, finding a product, the cart, checkout, and order confirmation. In an internal system, they may include creating a customer, approving a request, or processing an invoice. What matters is the outcome without which the user cannot complete their work.
Representative cases are enough to cover the complete journey through the user interface. Many combinations of prices, permissions, and error states can be verified faster and more precisely at the API or application-logic level. The result is a smaller but more useful suite.
What is better left to people
Exploratory testing looks for problems that do not yet have a written expectation. The tester tries unusual approaches and asks questions that an automated scenario does not anticipate.
Usability and clarity require human judgement. An automated test can detect a technical change in appearance, but it cannot decide on its own whether the ordering process is confusing for a customer.
One-off or short-lived features may not repay the time spent on automation. If they carry high risk, however, the decision should be based on impact rather than frequency alone.
What to watch out for
Priorities are not permanent. A new sales channel, a payment change, or frequent incidents can alter the order. Review the list regularly and track the maintenance time and number of useful findings for every scenario.
What you gain
- The first tests protect processes that matter to customers.
- The team can justify both the order and what it is not automating yet.
- A smaller number of well-chosen tests provides faster feedback.
- Manual testing remains where human judgement provides the greatest value.
