Should I automate tests for applications that have been around for a while?

Oct 7, 2025

For long-lived applications the decision to automate depends on how often they change and how often tests must be re-run. If releases are regular and you need repeated validations, automate the repeatable checks to gain speed and consistency. If the app rarely changes and tests run once in a while, manual can be enough. Choose based on release cadence, rerun frequency, and ROI.
