Breaking the QA Barrier: Build a Test Automation CoE That Scales Excellence

Quality is one of the key factors driving software industry success, enabling enterprises to build brand loyalty and offer seamless services. There are plenty of strategies for maintaining software quality. Some enterprises keep it in-house, while others outsource it to a professional digital assurance services provider, like Tx. Apart from these, one more option produces the most reliable results: creating a Test Automation TCoE.

Txs’ Test Automation Center of Excellence enables enterprises to upscale the effectiveness and accuracy of software QA by following a standardized approach. It consists of diverse testing processes, tools, people and governance structure, operating as a shared services function to provide enterprises with maximum quality benefits across the entire testing process.

What is a Test Automation Center of Excellence (CoE)?

A Test Automation CoE is a dedicated unit within an enterprise that focuses on creating, scaling, and optimizing the test automation process. Although like TCoE, a Test Automation CoE particularly targets automation as an enabler of quality, efficiency, and speed in the SDLC. It helps seamlessly implement test automation practices across projects, teams, and business units. Key Functions of a Test Automation CoE include:

• Establishing an automation strategy based on the enterprise automation vision, goals, and roadmap for quality.

• Standardizing relevant tools and frameworks like Appium, TestComplete, Selenium, Playwright, UiPath, Tosca, Katalon or Cypress, and creating a reusable automation framework and libraries.

• Develop guidelines for coding standards, version control, test data management, and CI/CD integration, and establish practices for what to automate and what not to.

• Training QA teams and developers in test automation techniques and tools and providing hands-on support.

• Keep track of KPIs like automation coverage, execution time, script reliability, automation effectiveness and ROI to identify bottlenecks and optimization areas.

• Enable continuous testing to support test automation within CI/CD pipelines and ensure each test case is integrated and can run across development, staging, and production environments.

• Maintain governance for automation scripting and ensure the scalability and maintainability of automation assets.

Key Components of the Test Center of Excellence

Why Build a Test Automation Center of Excellence?

This is not because of the tools that fail at scale, but because they are not consistent. A Test Automation Center of Excellence helps companies make sure that automation is repeatable, measured, and in line with their business goals.

Businesses put money into a Test Automation CoE for these main reasons:

• Centralized control over what is automatic, how it is done, and when it happens
• Frameworks and ways of writing code that are standardized and make scripts less fragile
• The best ways to handle test data, settings, and CI/CD alignment
• Less work being done twice by different teams and projects

This really means that automation is no longer just an experiment at the project level; it’s now a feature that the whole company can use.

What Are the Roles and Responsibilities in a Test Automation CoE?

• A user group, test architects, and automation engineers
• A CoE only works when it’s clear who owns what. Each job is about scale, not just doing things.

The most important jobs in a Test Automation CoE are:

Test Architects

Test architects set up center of excellence models, tool strategies, automation patterns, and long-term plans.

Automation Engineers / SDETs

Make and take care of automation assets that can be used again and again, add tests to processes, and make sure they are reliable.

QA Leads & Product Owners

Get the requirements for automation to match the business risk, release goals, and effects on customers.

DevOps & Platform Teams

Allow CI/CD integration, stable environments, and scalable performance.

Clear separation of roles keeps automation from becoming everyone’s job and no one’s duty.

Why is having a Test Automation CoE beneficial for a Business?

Standardizing Testing Practices:

The test automation process is usually fragmented in enterprises. This means teams use different tools, write inconsistent scripts, and follow different standards. A Test Automation CoE resolves this by creating a common framework and governance model across projects. It also facilitates reusability and consistency of automation code and reduces duplication of technical debt and QA efforts.

Better QA Control:

With a centralized setup, QA will no longer be an isolated or reactive process. It will become a proactive and measurable function that enables real-time visibility across testing status and results. Enterprises can also implement KPIs and dashboards to track automation coverage, defect leakage, and ROI. In short, it can enable better control over the QA process and outputs.

Faster Time–to–Market:

Speed is crucial to staying competitive in today’s AI-controlled environment. CoE contributes to this by embedding automated tests into CI/CD pipelines for continuous testing. It also enables faster regression cycles without compromising coverage and supports rapid innovation and frequent software releases.

Better Compliance and Risk Management:

Industries like BFSI and healthcare are highly regulated industries. CoE ensures testing practices align with regulatory and security standards, automates critical checks to reduce human errors, and provides auditable test records and traceability for compliance reporting.

Alignment with Business Goals:

A mature CoE setup makes test automation a business enabler. It helps align testing priorities with CX, business continuity, and revenue impact. Enterprises can streamline product launches, support digital transformation, and confidently handle projects.

Promotes innovation:

A mature CoE helps promote usage of innovative solutions across different teams through common tools, utilities, and practices.

Case Study: How a QA Center of Excellence Enabled Quality at Scale for US Insurance

A leading U.S.-based property and casualty insurance company selected Tx to establish a QA Center of Excellence (QA CoE) as part of their digital transformation strategy. The client aimed to modernize their software delivery by centralizing QA practices, improving software quality, and reducing time-to-market. Tx implemented a structured CoE framework aligned with TMMi maturity models, standardized test management processes, introduced governance mechanisms, and fully automated the regression suite for their insurance applications. It helped establish consistent test planning, defect tracking, environment management, and reporting across the enterprise.

The QA CoE significantly improved production stability, automation maturity, and release speed. The automated regression suite helped reduce the overall testing cycle by 43% and time to market by 30%. The client experienced better QA control, higher productivity, and faster delivery cycles while maintaining regulatory compliance. Most importantly, the centralized testing approach directly enhanced customer satisfaction by reducing defects in production and supporting a more stable, reliable insurance platform. This case study reinforces the value of a QA CoE as a strategic enabler for quality at scale, especially for businesses in highly regulated industries like insurance.

How to Measure the Effectiveness of Your CoE?

You can’t grow something that you can’t measure. At this point, a mature Test Automation CoE is driven by metrics that measure results, not script numbers.

Key KPIs to measure how well the CoE is working:

• Coverage of automation: The share of test cases that are automated across key flows
• Defect detection rate: defects found before production vs. after release
• Execution cycle time: the time it takes for failure testing and release validation
• Automation ROI: Cost saves from less work being done by hand and faster releases

These metrics help leaders explain investments in the CoE and keep improving the automation strategy.
