to your stack & domain
TestGrid's AI software-testing agent that creates test logic and code and assists execution across testing workflows. Deployed, integrated and governed inside your QA workflows by Scrums.com.
How this operator works
every way of working, already decidedOwns 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.
Embedded, async-first, instrumented
Works inside your repos, your CI and your rituals. Daily written standups, decisions logged. No status-meeting tax.
Runbooks, canaries, reversible deploys
Every change gated and reversible. Incidents get a timeline and a postmortem; nothing ships without a rollback.
Plugged into your Slack & rituals
Joins standups and retros, reports weekly against the goal. You get an operator, not a queue.
Brings a pre-wired stack or adopts yours
Infrastructure and observability as code by default. No bespoke setup tax to absorb.
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.
