COMPUTER USE / USE CASE

Computer use for QA testing

Combine deterministic release checks with bounded exploratory interface testing.

05Outcome

Define the job

Exercise a defined application journey in a test environment and collect evidence of the resulting state. Distinguish regression assertions from exploratory findings: a model’s opinion about the UI should not silently become the release gate.

API FIRST?

Should this use computer use at all?

Use unit and API tests for logic that does not require an interface. Use browser tests where rendering, navigation, form behavior, or session transitions are the subject of the test.

Architecture options

Deterministic regression suite

Use explicit browser assertions for known signup, login, and checkout paths. Isolate test accounts and reset fixtures so one test does not depend on data left by another.

Constrained exploratory agent

Give an agent a test charter and a sandbox account, then record its navigation and suspected defects. Convert confirmed repeatable findings into deterministic checks where practical.

Failure modes & approval

Where the workflow can break

An exploratory agent may report a defect that is actually a test-fixture issue.
Parallel tests sharing an account can interfere with server-side state.
A test pointed at a live payment path can create real consequences.

Human approval point

Permit synthetic operations only in the approved test environment. Require explicit review before any test can reach production records, real messages, or real payment instruments.
