Background

A fast-growing digital commerce company outgrowing brittle scripts and slow manual test authoring.

Modern software teams ship continuously, but quality assurance often becomes the bottleneck—manual test creation is slow, automated scripts are brittle, and regression cycles stretch release timelines.

A fast-growing digital commerce company set out to modernize its testing function with generative AI, accelerating test authoring and execution while expanding coverage and reducing the maintenance burden that had been consuming engineering capacity.

The client is a fast-growing digital commerce company delivering a feature-rich digital platform with frequent, iterative releases.

Its engineering and QA teams were responsible for safeguarding quality across a complex web application spanning critical user journeys such as onboarding, checkout, and payments.

As release velocity increased, the existing automation suite struggled to keep pace, and a growing share of engineering time was spent maintaining brittle tests rather than building new coverage.

The company needed an AI-driven approach to testing that could scale with its release cadence.

Challenges faced & defined solution

5 real bottlenecks. 6 matching fixes.

Every operational bottleneck reported was matched to the workstream(s) that resolved it.

The challenge

Slow Manual Test Authoring

Writing and updating test cases by hand could not keep pace with frequent releases, creating a QA bottleneck and delaying delivery.

Defined solution

AI-Generated Test Authoring

Generated test cases and executable scripts directly from requirements, user stories, and application flows, drastically reducing manual authoring effort.

The challenge

Brittle, High-Maintenance Scripts

UI and locator changes routinely broke automated tests, so engineers spent more time fixing tests than expanding coverage.

Defined solution

Self-Healing Execution

Automatically adapted tests to UI and locator changes at runtime, reducing breakages and maintenance overhead.

The challenge

Coverage Gaps

Untested paths across critical journeys allowed defects to reach production, eroding user trust.

Defined solution

Coverage Analytics

Identified untested paths and continuously improved test completeness across critical journeys.

The challenge

Long Regression Cycles

Full regression runs took days, slowing releases and extending time-to-market.

Defined solution

Risk-Based Prioritization

Ran the highest-value tests first within CI/CD pipelines, surfacing critical defects earlier in the cycle.

The challenge

Scaling Complexity

As the application grew, test maintenance became increasingly costly and difficult to scale with the existing approach.

Defined solution

CI/CD Integration & Tech Stack

Built to integrate with existing pipelines using LLM-driven test generation, parallel execution, and standard automation frameworks for fast, reliable feedback.

Natural-Language Authoring

Allowed both QA engineers and non-technical contributors to define and review tests in plain language.

The Impacts

Real, measurable improvements in authoring speed, coverage and release confidence.

Faster Test Creation

AI-generated cases and scripts compressed authoring time and accelerated coverage expansion.

Lower Maintenance Burden

Self-healing reduced test breakages, freeing engineers to focus on building rather than fixing tests.

Broader Coverage

Coverage analytics closed gaps across critical journeys, catching defects before production.

Shorter Release Cycles

Faster, prioritized regression runs accelerated releases and improved confidence.

Higher-Value QA Focus

QA shifted from script maintenance to exploratory and risk-based testing.

Faster Regression Cycle Time

Regression cycle time was likely reduced from around 3 days to under 6 hours.

Improved Release Frequency and Confidence

Release frequency and confidence likely improved as QA shifted from maintenance to exploratory testing.
