Quality assurance
Find the defects before your users do. And before any of that: work out whether what you have is a testing problem at all, because often it is not.
Diagnose first
Three symptoms that look identical from the outside and have entirely different causes. Buying testing for the third one wastes your money and ours.
Automation is an investment with a break-even point. A test that runs on every release for two years repays writing it many times over; a test written once for a feature nobody touches again never does.
So the honest rule is not “automate everything”. It is: automate the paths where a failure would be serious and the check is identical every time — logging in, taking a payment, saving the thing the business runs on.
Anything where the question is “is this right?” rather than “did this run?”. Whether a layout is usable on a small screen, whether an error message makes sense, whether a new feature interacts strangely with an old one.
Exploratory testing — someone deliberately trying to break it, without a script — finds the class of defect no automated suite was ever written to look for, because nobody had thought of it yet.
Use this without hiring anyone
Walk through the two or three journeys the business actually depends on, end to end, as a real user with real data. Not the feature you just changed — the ones you did not.
Most testing is done by someone with full permissions. Log in as the most restricted role that exists and try the same journeys.
Empty required fields, an absurd number, a date in the past, a file of the wrong type, the same form submitted twice. How the software behaves when it is misused is the part users meet and specifications rarely cover.
A narrow browser window is not a phone. Touch targets, the on-screen keyboard covering the field you are typing in, and a form that cannot be submitted because the button is off-screen.
Re-check whatever was fixed in the previous two releases. The cheapest regression test available, and the one that needs no tooling at all.
Cancel halfway. Hit the browser's back button mid-flow. Refresh on a confirmation page. A broken exit is how half-finished records get written.
The single most useful item on this list. An untested area you know about is a risk; one you have forgotten about is an incident.
What an engagement produces
Not a generic matrix of test types. The journeys that matter to your business, in priority order, with the reason each one is on the list.
Each with the steps to reproduce it, what happened, what should have happened, and where it sits relative to everything else. A defect nobody can reproduce is not a finding.
The checks that run on every release, in your repository, runnable by your team or the next supplier. It is yours, and it is the reason ongoing changes stay affordable.
The areas we did not test and why — out of scope, no test data, no access to a system. This is the item that protects you, because it turns an unknown risk into a decision you get to make.
Describe what breaks and how often. Telling you the problem is not testing costs us a sale and saves you a quarter.
