Exploratory testing, UAT, and usability review, done by engineers

Manual testing services that catch what automation can’t

Automated suites are good at repeating the same steps. They are bad at noticing a confirmation message that doesn't make sense, or a workflow that technically works but feels wrong. GoGreenlit's manual testing engineers run exploratory sessions, user acceptance testing, and usability review directly inside your sprint, the judgment automation can't replicate.

What manual testing actually covers

Five techniques, each suited to a different kind of risk, run by an engineer who reads your product the way a real user would.

Exploratory testing

Investigative sessions run against a defined charter, not a rigid script, so a tester can follow a hunch about where the product might break.

Smoke testing

A fast pass over critical paths after every build or deployment, so a broken login or checkout gets caught before anyone else touches the release.

User acceptance testing

Structured validation against your actual acceptance criteria, run by someone who reads the ticket the way a stakeholder will.

Usability testing

A check for whether a feature works the way a real user expects it to, not just whether it technically functions.

Accessibility spot-checks

Keyboard navigation and screen reader passes on new features, catching the accessibility gaps a purely visual review would miss.

When manual testing is the right tool

Automation earns its keep on repetition. These are the situations where a person still has the advantage.

  • New features where the requirements are still evolving sprint to sprint.
  • Complex, multi-step workflows a single scripted test can't cover end to end.
  • Edge cases that need business context to recognize as a problem at all.
  • Situations where judgment matters more than repetition.
  • A second pass after automation runs, to catch what a script isn't built to see.

How we run manual testing inside your sprint

Planning

Test cases and exploratory charters get written against the sprint's actual scope, before a single line of code ships.

During-sprint execution

Sessions run alongside development, not queued up for the end of the sprint, so a defect surfaces while it's still cheap to fix.

Release sign-off

A final pass against acceptance criteria before anything ships, so sign-off means something.

Retrospective participation

Your tester joins the retro like any other engineer, feeding what they found back into the next sprint's planning.

What you get from a manual testing engagement

Every session leaves something behind, not just a pass or fail on a ticket.

Test case libraries

Living documentation you keep, not a one-off deliverable.

Defect reports

Reproducible, prioritized, and filed where your team already works.

Exploratory charters

A record of what was investigated and why, not just what passed.

Coverage summaries

A sprint-by-sprint view of what got tested and what didn't.

Escaped defect records

A running account of what reached production, and why, so it stops repeating.
