How a Tier-1 Telecom Provider Cut Testing Time in Half with CoTester

Summarize this blog post with:

A Tier-1 telecom provider was struggling to modernize its QA processes while preparing for large-scale 5G and VoLTE rollouts. Their testing operations were spread across multiple regional labs, each running on outdated setups with fragmented tools.


The Problem

The telco’s existing QA framework had become a barrier to speed and innovation.

They faced:

  • Rising costs of maintaining multiple labs and device inventories
  • Slow regression cycles, often stretching beyond release deadlines
  • Limited automation, forcing teams to repeat manual workflows
  • Compliance risks tied to data residency and audit readiness
  • Low visibility across QA teams, with test results scattered across tools and regions

Their previous cloud testing vendor added to the friction — execution was unreliable, device access was restricted, and hidden infrastructure costs piled up.


The CoTester Deployment

To address these challenges, the operator implemented a hybrid model: TestGrid’s on-premise infrastructure paired with CoTester, the AI agent for software testing.

Key enhancements included:

  • AI-Driven Regression
    CoTester took over nightly regression runs, generating stability reports and alerting devs before the next sprint started.
  • Centralized Test Management
    Manual, integration, and performance tests were consolidated into one platform — reducing tool sprawl.
  • Enterprise-Grade Security
    Role-based access controls, SSO integration, and detailed audit logs ensured compliance with telecom regulations.
  • Seamless Integrations
    • Jira for automated bug ticket creation with screenshots and logs.
    • Jenkins + Azure pipelines for CI/CD-driven test execution.
    • Slack for in-chat notifications, bug reporting, and sprint updates.

The Impact

Within six months, the telco recorded measurable improvements:

  • 50% reduction in test cycle duration — releases that once took weeks were executed in days.
  • 35% savings in operational spend by retiring legacy lab hardware and redundant tool licenses.
  • Stronger compliance posture, with all data and logs retained inside local infrastructure.
  • Faster 5G deployment timelines, as critical bugs surfaced earlier in the cycle.
  • Improved collaboration, with developers and testers working in real-time via Slack + Jira integrations.

In Their Words

“With CoTester, we don’t just test faster — we test smarter. Automation, compliance, and collaboration are built into one platform. For a telco at our scale, that’s game-changing.”
