Original OrbTrail editorial, written in our own language from the reference publication.
A Flow can finish without an error and still produce the wrong answer. Debug logs explain the path that ran, but they do not guarantee that a record ended in the expected state. The most important shift in the new testing tools is exactly that: attention moves from successful execution to correct outcomes.
Assertions turn a business rule into a testable question. If a case has an Escalated status, for example, the corresponding field should be checked at the end of the Flow. A test starts with a known record, runs the automation and compares the actual result with the expected one.
Useful coverage requires variety. Teams should test the record that must change, the record that is already correct and the record that should remain untouched. Test suites collect those scenarios and run them together, allowing a later Flow change to reveal regressions before users encounter them.
For admins, this brings declarative automation closer to the testing discipline long used with Apex. The goal is not to produce the largest number of tests. It is to protect the business outcomes that matter most. Start with critical rules and cases where a silent failure would cause the greatest damage.
