How a Telecom Enterprise Cut QE Tool Costs and Saved Millions With TestGrid

A large telecom enterprise was managing quality engineering through a disconnected mix of device vendors, browser testing tools, simulator providers, custom frameworks, legacy scriptless platforms, and separate reporting dashboards.

Years of acquisitions, vendor decisions, and business-unit-level tool adoption had created duplicated infrastructure, rising costs, security gaps, and limited visibility into quality. Teams had capable tools in place, but those tools were not working as one system.

To address this, the telecom enterprise began a multi-year QE transformation program with an enterprise QE transformation partner, using TestGrid as the platform foundation.

The goal was clear: consolidate testing infrastructure, modernize legacy automation, reduce vendor dependency, and give engineering and leadership teams one reliable source of quality truth.

The Challenge

The telecom enterprise needed to modernize quality engineering without disrupting large-scale testing programs already serving multiple business units. The team faced several challenges:

• Disconnected testing infrastructure: Different teams used different public cloud device vendors, on-prem device vendors, browser testing vendors, simulator providers, legacy scriptless tools, custom frameworks, and homegrown reporting systems.

• Duplicated vendor spend: Overlapping tools and infrastructure increased licensing costs and created avoidable operational overhead.

• Limited central governance: Device labs, hosted environments, browser infrastructure, and reporting systems were managed separately, making it difficult to enforce common standards for security, usage, and reporting.

• Legacy automation lock-in: Large volumes of existing test assets were tied to proprietary scriptless platforms, limiting reuse, portability, and CI/CD readiness.

• Scattered quality data: Test results were spread through web, mobile, API, device lab, and legacy platforms, leaving leadership without a single view of release readiness.

The result was a QE environment that had become expensive, difficult to govern, and harder to scale with release demands.

Why Existing Approaches Fell Short

The enterprise already had device access, browser testing, simulators, automation frameworks, reporting dashboards, and legacy platforms. But each system operated in isolation. That means teams could improve individual tools, but that didn’t solve the larger issue.

Quality engineering had become fragmented at the infrastructure level. The organization needed a unified QE platform model that could bring device labs, browser infrastructure, test automation, reporting, and governance into one operating layer.

The TestGrid Approach

The telecom enterprise used TestGrid as the platform foundation for a structured QE modernization program. TestGrid provided the common execution, automation, device access, and reporting layer needed to bring the program together.

The transformation followed a three-pillar model:

• Infrastructure consolidation
• QE platform modernization
• Unified quality intelligence

The approach was foundation-first. Infrastructure consolidation created the base for automation modernization. Automation modernization then fed a unified quality intelligence layer for engineering teams and leadership.

Pillar 1: Infrastructure consolidation

The first priority was to reduce vendor sprawl and move testing infrastructure into a single enterprise-grade platform. With TestGrid, the enterprise could deploy a consolidated model that included:

• On-prem device labs for secure locations, regulatory requirements, and internal control.
• Hosted device labs for elastic capacity, large-scale device access, and centralized management.
• Hybrid access so teams could use on-prem, hosted, and browser infrastructure through one platform.
• A Center of Excellence model for lab governance, security, vendor operations, and reusable operating practices.

Pillar 2: QE platform modernization

Once the infrastructure foundation was in place, the next priority was automation modernization.

The telecom enterprise had thousands of legacy test assets tied to proprietary scriptless tools. These assets carried years of testing knowledge, but the underlying platforms created cost, lock-in, and modernization challenges.

TestGrid helped move those assets toward open, CI/CD-ready automation. The modernization model included:

• Automated conversion: Custom accelerators converted legacy test assets into modern automation.
• Expert validation and remediation: The enterprise QE transformation partner handled validation, optimization, manual remediation, and framework modernization.
• CoTester by TestGrid: Test assets were converted into Selenium-based, open-architecture, CI/CD-ready automation.
• Customer-owned automation: The enterprise reduced proprietary lock-in and retained ownership of its automation assets.

This allowed the organization to preserve existing test coverage while moving toward a more flexible automation model.

Pillar 3: Unified quality intelligence

Before the transformation, quality data was scattered through testing tools, teams, frameworks, device labs, and legacy systems. Engineering teams had operational data, but leadership did not have a single trusted view of release readiness.

TestGrid created a unified reporting layer that aggregated results from multiple testing programs. The quality intelligence layer included:

• API-based aggregation of test results from multiple frameworks
• Executive dashboards for release readiness, regression status, quality trends, defects, and coverage
• Team-level analytics for engineering insight and business visibility
• A single source of truth for every quality program

The Impact

The telecom enterprise’s QE transformation delivered measurable improvements in cost, automation, governance, release speed, and leadership visibility. Key outcomes included:

• Vendor consolidation: Overlapping testing vendors were eliminated across business units.
• $M+ licensing avoided: The enterprise avoided millions in licensing costs through platform rationalization and reduced dependency on overlapping tools.
• Thousands of assets modernized: Existing test assets were migrated from legacy platforms into a more open, future-ready automation model.
• Around 70% automated migration: Approximately 70% of migration was automated, with targeted expert intervention used where required.
• Faster releases: Regression cycles accelerated as testing infrastructure and automation became easier to access, govern, and scale.
• Better security: The hybrid on-prem and hosted architecture brought testing infrastructure under centralized governance.
• One source of quality truth: Leadership gained unified visibility into quality programs, improving confidence in release readiness.

What Changed for the QE Organization

Instead of coordinating separate vendors for devices, browsers, simulators, automation, and reporting, teams could work through a unified QE platform. On-prem and hosted environments became part of one model.

Legacy automation assets could be modernized instead of discarded. Quality results could be aggregated into one reporting layer instead of remaining trapped in disconnected dashboards. For leadership, the biggest change was visibility.

Release readiness became easier to assess. Quality trends became easier to compare. Vendor and licensing decisions became easier to rationalize.

The QE organization gained a repeatable modernization model for reducing cost, improving governance, and scaling quality engineering across telecom business units.

What the QE Leader Had to Say

“Before this transformation, we had capable teams and capable tools, but quality data was scattered everywhere. Every business unit had its own systems, dashboards, and dependencies. TestGrid helped us move toward one QE platform model, modernize legacy automation, and give leadership a view of release readiness we could actually trust.”

It’s Time to Future-Proof Telecom QE

For this telecom enterprise, consolidation was the first step. The bigger shift was creating a QE model that can keep pace with how telecom systems are changing.

As 5G, cloud-native services, edge deployments, new devices, and faster release cycles add more complexity, the organization now has one platform foundation for infrastructure, automation, reporting, and governance.

With CoTester, that foundation can extend into AI-powered testing, where teams can generate tests from requirements, improve automation coverage, and keep human approval in the workflow.

If your organization is dealing with tool sprawl, rising testing costs, legacy automation, or disconnected quality reporting, TestGrid can help you move toward a unified, AI-ready QE model.
