Test strategy
A testing approach sized to the risk each part of the system carries, rather than uniform coverage nobody maintains.
QA, Modernisation & Reliability
Legacy is not about age. It is about whether you can change something safely — and how long it takes to find out that you could not.
Overview
The instinct with an ageing system is to start again. It is rarely the right call: a rewrite pauses all business value for months, and the second system reliably rediscovers the edge cases the first one had already solved.
The alternative is a phased approach — assess honestly, put testing around what exists, then replace in slices while the system keeps running. Less dramatic, considerably less risky.
Sometimes the assessment does conclude that a rebuild is right. When it does, that is a documented finding rather than a starting assumption.
Scope
A testing approach sized to the risk each part of the system carries, rather than uniform coverage nobody maintains.
Automated coverage of the journeys and interfaces that would hurt most if they broke.
A suite that makes releases routine, plus the release process around it.
Load and response profiling against realistic usage, with the bottlenecks identified rather than guessed.
An honest read on the codebase, data, dependencies, risk and what it would genuinely cost to change.
Refactoring, migration, UI renewal, integration layers and platform decomposition — delivered in slices.
Where it fits
If none of these sound familiar, this is probably not the capability you need — and we would rather point you somewhere more useful.
Every release breaks something unrelated
Regression coverage on the critical paths, so side effects surface before users find them.
Only one person understands the system
Documented architecture, tests that express intended behaviour, and deliberate knowledge transfer.
The platform is slow and nobody knows why
Profiling against realistic load to find the actual bottleneck rather than optimising by intuition.
Upgrading a dependency is too risky to attempt
Test coverage first, then staged upgrades with a rollback path.
An ageing PHP or WordPress build is slow and risky to change
Assessment of the codebase, plugins and dependencies, then staged upgrades — modern Laravel where a framework is warranted, a hardened and properly maintained WordPress where it is not.
A rewrite has been proposed but the case is unclear
A written assessment comparing phased modernisation against rebuild, with cost and risk for each.
Delivery
Read the code, the data and the incident history. Establish real risk rather than assumed risk.
Put testing and monitoring around what exists, so change becomes measurable.
Break modernisation into slices that each deliver value and can be stopped between.
Deliver slice by slice, with the old and new coexisting where necessary.
Maintain coverage, keep dependencies current, and prevent the next legacy build-up.
Technology
Selected around product goals, integration needs, security requirements, team fit and long-term maintainability — not trends alone.
Codebase summarisation and test-case generation can accelerate an assessment of an undocumented system — always reviewed by an engineer, never trusted blind.
