Penetration test of a district council parking app

District council, Cotswolds

Challenge
The council's parking permit app, built by a small supplier, handled payment card details and vehicle registrations for 18,000 residents. It had never been independently tested, and the council's cyber insurance renewal required evidence of a test within the quarter.
Solution
AGS carried out a scoped penetration test of the mobile app and its backend APIs, reported findings with reproduction steps and severity ratings, and worked with the supplier to verify each fix. A re-test confirmed the closures and produced a letter suitable for the insurer.
Results
  • 2 high and 7 medium findings identified and fixed
  • Re-test completed 3 weeks after the initial report
  • Insurance evidence delivered 11 days before the deadline

Replatforming a high-street homewares retailer's online shop

High-street homewares retailer, UK

Challenge
The retailer's web shop ran on a heavily customised platform that had fallen two major versions behind. Page loads averaged over four seconds on mobile, promotions needed a developer to set up, and the Christmas peak had taken the site down twice in the previous two years.
Solution
We rebuilt the storefront as a headless front end on a composable commerce back end, migrated catalogue and order history, and moved hosting to a managed cloud platform with autoscaling. Merchandisers now run promotions themselves. We load-tested to three times the previous peak before cutover.
Results
  • Mobile page load down from 4.2 seconds to 1.3
  • First peak season handled with 0 minutes of downtime
  • Promotion set-up moved from developer tickets to 15 minutes in admin

Release management for a regional cable operator field app

Regional cable operator, Southeast

Challenge
The technician app used by 400 field staff shipped updates irregularly, often breaking something in the process. Each release needed a week of manual testing, technicians learned to avoid updating, and at one point three versions were in use with different work-order formats.
Solution
AGS took on the app's release management: an automated regression suite, device lab testing on the operator's actual handset models, staged rollouts to 10% of technicians first, and a fixed fortnightly cadence. The operator's product owner still decides what ships; we make sure it ships cleanly.
Results
  • Release cadence moved to every 2 weeks, consistently
  • Post-release defects reduced by 70% over 6 months
  • Version spread reduced from 3 to 1 within 2 releases

Mobile puzzle game for a Leeds indie studio

Independent game studio, Leeds

Challenge
A three-person studio had a proven puzzle prototype and a publishing deal with a fixed launch date, but no capacity to build 120 levels, two platforms and the live-ops features the publisher expected. Their previous release had shipped with performance problems on older Android devices.
Solution
AGS provided a Unity team of four for five months: level tooling so the designer could build levels without engineers, iOS and Android builds, analytics events and a remote configuration system for live tuning. Our QA team tested on 30 devices, including the low-end Android set that caused trouble before.
Results
  • 120 levels shipped on both platforms on the launch date
  • Crash-free sessions at 99.4% in the first month
  • Day-7 retention of 24%, above the publisher target

FAQ

Quality Assurance: questions, answered.

What does AGS quality assurance cover?

We provide manual and automated test coverage, performance testing, test strategy, and regression suites. Coverage is built around the paths your users actually take, not just the ones easiest to script, and mapped to risk rather than feature count, so testing effort lands where a failure would hurt most.

What's the right balance between manual and automated testing?

It depends on the work. Automated suites handle scripted, repeatable checks and regression at scale; human judgement catches the edge cases scripts miss. We design the mix deliberately per product, so automation covers volume while manual QA covers the nuanced paths, including accessibility gaps a script would walk straight past.

How do you decide what to test first?

We map the paths your users actually take through the product, then build test coverage around real risk areas rather than raw feature count. That risk-mapped strategy means the highest-impact failure points get tested first, which is how one client cut regression cycle time in half without losing coverage.

Can you catch performance problems before real traffic hits?

Yes. Load and stress testing run before real traffic finds the breaking point, exposing bottlenecks while there is still time to fix them. One client's load testing caught a bottleneck before a peak trading day, avoiding an outage when the volume that would have triggered it finally arrived.

Catch it before your customers do.
