What software testing is for
Software testing answers a practical question: does this release do the work, for the people we named, on the platforms we promised, without wrecking the data. SJ Technologies is a UK IT agency. QA is part of delivery, not a department you hire the week of launch.
A test that never fails is a ceremony. A test that cannot be run twice is a demo. We write tests you can run again on the next build.
What to test, in order
Start with the journeys that lose money or harm a record. Then integrations, permissions, and the browsers and devices you claim to support. Performance on the pages that must be fast. Accessibility on the forms that must be completed. Security tests for the threats that apply, not a generic scan printed as a trophy.
Automated checks belong on the path that is stable. Exploratory testing belongs on the path that is new. Both are QA. Neither replaces the other.
Acceptance criteria written with the story, not after coding. Regression on the last release’s bugs, or they will return. A staging environment that is not a rumour. A go/no-go based on evidence, not on a date in a slide.
QA inside the same team
We do not throw builds over a wall. Testers sit with developers and the named lead. Defects are cheap when they are found next to the person who can fix them.
If you already have a product, we can run a test pass against a written scope: devices, browsers, roles. If we are building it, QA is in the estimate.
Before you ship
You should be able to say what was tested, what failed, what was deferred, and who accepted the residual risk. That is professional software testing. A green pipeline with no human journey is not.
Ask us for QA on a web, mobile or software release. Bring the environments and the list of what “done” means. We will test that.
