Expected and actual are simple labels, but they prevent many bug reports from becoming arguments about what the tester meant.

In this guide: Why separating intended behaviour from observed behaviour makes Android test reports easier to understand and verify.
Important context

Testing practice: For Expected describes the intended outcome, define a reproducible starting state, perform one controlled change at a time and record the result. Good testing evidence helps another person repeat the same path without guessing what happened.

Evidence quality: A useful report separates observation from theory. Record version, device context, steps, expected result and actual result while removing passwords, authentication codes and unrelated personal information from evidence.

Expected describes the intended outcome

The expected result should come from product requirements, visible design or a reasonable documented workflow.

Avoid inventing an expectation after the failure just to make the report sound stronger.

Key concepts for Expected result versus actual result in software testing
Key concepts from this guide.

Actual describes observation

Write what the app displayed, did or failed to do.

Use concrete details such as button stayed disabled rather than saying the app was bad.

Key ideas from this guide.

The difference defines the issue

A bug becomes clearer when the mismatch between expected and actual is explicit.

This lets a developer verify whether the behaviour is truly unintended.

Screenshots support actual results

Visual evidence can confirm text, layout or state.

Use evidence as support, not as a substitute for written steps.

Requirements can also be wrong

Sometimes the app behaves consistently with code but the requirement or UX is unclear.

Testing can reveal specification problems as well as implementation bugs.

Frequently asked questions

Can expected result come from the UI itself?

Yes, when labels and workflow clearly communicate intended behaviour.

Is every unexpected result a bug?

Not always; it may expose unclear requirements or misunderstood design.

Why write actual result in detail?

Specific observations make verification faster.
