From manual QA decisions to agent-led testing intelligence

How Nagarro helped a large digital services organization accelerate releases, reduce test instability, and make QA decisions smarter with AI agents

the challenge

While the client’s QA ecosystem had become increasingly complex, some critical testing decisions continued to remain manual, inconsistent, and difficult to audit.


Key challenges included:

  • No intelligent mechanism to determine which tests should run per code change.

  • UI selectors frequently broke after routine front-end refactors.
  • Manual selector repair consumed hours of engineering effort.
  • Flaky tests caused repeated pipeline failures without quarantine mechanisms.
  • No shared learning across testing disciplines and agents.
  • Risk-based test prioritization was manual, subjective, and difficult to audit.

the solution

Nagarro introduced an agent-based testing framework to automate QA decisions, reduce flakiness, and improve continuously with every release.

 

The solution provided:

  • A MACT framework with seven specialized AI agents collaborating on test decisions.
  • Intelligent test selection to decide which tests to run, skip, or prioritize for each code change.
  • A three-pass decision protocol – analyze, refine, and consensus – where agents shared signals, refined findings, and voted on the optimal test plan.
  • A self-healing agent that detected broken UI selectors and recommended confidence-scored alternatives.
  • A continuous learning loop using historical correlation analysis, adaptive thresholds, and trend detection.
  • A weighted consensus model with domain-authority tie-breaking and veto power for critical agents such as sanity and security testing.

the outcome

The AI-led testing framework enabled faster, more reliable releases with complete transparency and compliance readiness.

 

This engagement delivered:

  • 40% reduction in regression execution time through intelligent test selection.

  • 50% fewer flaky-test-induced pipeline failures through automated handling.
  • Near-zero UI selector maintenance effort through self-healing locator repair.
  • Continuous improvement in decision accuracy through correlation analysis and adaptive thresholds refined with each release.
  • Full audit trail of test decisions stored as structured JSON artifacts. 

The breakthrough was not running tests faster but building measurable, auditable confidence in every release. This gave the client the velocity, reliability, and compliance readiness needed to scale modern AI services across business units at enterprise pace.
