How this operator works

every way of working, already decided
A · capability focus

Owns the system, not the ticket

Takes end-to-end ownership of a service or surface. Design, delivery, on-call. And is measured on outcomes, not hours.

B · ways of working

Embedded, async-first, instrumented

Works inside your repos, your CI and your rituals. Daily written standups, decisions logged. No status-meeting tax.

C · reliability posture

Runbooks, canaries, reversible deploys

Every change gated and reversible. Incidents get a timeline and a postmortem; nothing ships without a rollback.

D · comms & cadence

Plugged into your Slack & rituals

Joins standups and retros, reports weekly against the goal. You get an operator, not a queue.

E · tooling

Brings a pre-wired stack or adopts yours

Infrastructure and observability as code by default. No bespoke setup tax to absorb.

F · onboarding

Scoped, gated, reversible

Week-1 shadow, week-2 ownership, swap on request inside the trial window. No long-tail handover risk.

Overview

CoTester is TestGrid's AI software-testing agent. It creates test logic and test code, and assists execution across testing workflows — working alongside QA teams like an AI teammate trained for testing work. It is sold as commercial SaaS.

Through Scrums.com, delivery teams deploy CoTester into your engineering operations, integrate it with your testing workflows and pipelines, and govern its output — tracked on the SEOP.

·

What it does

Test logic generation

Creates test logic from your application and requirements, defining what should be verified.

Test code creation

Produces test code from that logic, reducing the manual scripting burden on QA engineers.

Execution assistance

Assists execution of tests across testing workflows, helping runs happen consistently.

Testing workflow support

Works across the testing workflow rather than one niche, supporting QA teams through the test lifecycle.

FAQs

How is this different from hiring more QA engineers?

CoTester adds AI capacity for the repeatable parts of testing — creating test logic and code and assisting execution — while your QA engineers direct strategy and review results. It complements rather than replaces the team.

What access does deployment need?

Access to the application environments under test, your test management and CI tooling, and test accounts for flows in scope. Scrums.com defines the exact access list during scoping.

How is its work governed?

Scrums.com scopes the agent to agreed environments and workflows, keeps human review on generated tests, and reports usage and outcomes via the SEOP.
