A comprehensive test data strategy should seek to improve the following areas:
- Data delivery: reducing the time to deliver test data to a development team or test team.
- Data quality: meeting requirements for high-fidelity test data.
- Data security: minimizing security risks without compromising speed.
- Infrastructure costs: lowering the costs of storing and archiving test data.
In this blog, we’ll dive into each of these areas, plus explore the solutions modern companies are using to tackle test data management at scale.
Test Data Strategy Factor #1: Data Delivery
Creating copies of real data from production environments for development or testing is typically a time-consuming, labor-intensive process that lags demand. Modern organizations need streamlined, repeatable processes for fast data delivery featuring:
- Test data automation: Modern DevOps toolchains typically include technologies to automate build processes, infrastructure delivery, and testing. However, organizations often lack equivalent tools for delivering test data at the same level of automation. A streamlined test data management strategy eliminates manual processes—such as target database initialization, configuration steps, and validation checks—providing a low touch approach for new ephemeral data environments.
- Toolset integration: A modern test data management approach should unify technologies for data versioning, data masking, data subsetting, and synthetic data creation. This requires that tools have open APIs or direct integrations to fully enable automated declarative workflows for both infrastructure and data.
- Self-service: Instead of relying on IT ticketing systems, a modern test data management approach leverages automation to enable users to provision test data on-demand. Self-service capabilities should extend not only to test data delivery, but also to versioning, bookmarking, and sharing. Individuals should be their own test data manager, leveraging features such as bookmark, refresh, rewind, archive, and share without waiting on database administrators (DBAs) or involving IT operations teams.
Test Data Strategy Factor #2: Data Quality
When IT Operations teams are creating test data—such as masked production data or synthetic datasets—they must balance requirements on three key dimensions:
Test Data Age
Due to the time and effort required to prepare test data, operations teams are often unable to fulfill ticketed demand. As a result, data often becomes stale in non-production, which can impact test quality and result in costly, late-stage errors. A test data strategy should aim to reduce the time it takes to refresh an environment, making the latest test data more accessible.
Test Data Accuracy
A test data management process can become challenging when multiple datasets are required as of a specific point-in-time for systems integration testing. For instance, testing a procure-to-pay process might require that data is federated across customer relationship management, inventory management, and financial applications. A successful test data management strategy should allow for multiple datasets to be provisioned to the same point in time and simultaneously reset between test cycles.
Test Data Size
In the interest of reducing storage footprints, developers may sometimes consider using data subsets in an attempt to improve agility. However, subsets can't satisfy all functional testing requirements–resulting in missing test cases and shifting issues right in the SDLC–increasing overall project costs.
A modern test data management solution should look to reduce the number of unmonitored copies of test data across environments, enable the sharing of common data blocks across similar copies (saving on storage), and reduce manual processes with increased workflow automation to save on operating costs.
Test Data Strategy Factor #3: Data Security
Masking tools like Perforce Delphix have emerged as an effective and reliable method of protecting sensitive production data that is moved into environments for testing. By irreversibly replacing sensitive data fields with fictitious yet realistic data values, masking ensures regulatory compliance by completely neutralizing the risk of data breach in test environments. To make masking practical and effective, organizations should consider the following requirements:
Complete Solution
Many organizations fail to adequately mask test data because they lack a complete solution with out-of-the-box functionality to discover sensitive data and then audit the trail of masked data. In addition, an effective approach should mask testing data consistently while maintaining referential integrity across multiple, heterogeneous sources.
No Need for Development Expertise
Organizations should look for lightweight masking tools that can be set up without scripting or specialized development expertise. Tools with fast, predefined masking algorithms, for example, can dramatically reduce the complexity and resource requirements that stand in the way of consistently applying masking.
Integrated Masking and Distribution
Only about 1 out of 4 organizations are using masking tools because of challenges delivering data downstream. To overcome this, masking processes should be tightly coupled with data delivery.
Organizations will benefit from an approach that allows them to mask data in a secure zone and then easily distribute compliant data to non-production environments, including those in offsite data centers or public clouds.

Test Data Strategy Factor #4: Infrastructure Costs
With the rapid proliferation of test data, test data management teams must build a toolset that maximizes the efficient use of infrastructure resources. Specifically, a test data management toolset should meet the following criteria:
Data Consolidation
It is common for organizations to maintain non-production environments where 90% of the data is redundant. A test data strategy should aim to consolidate storage and slash costs by sharing common data across environments—including those used not only for testing, but also development, reporting, production support, and other use cases.
Data Archiving
A test data strategy should make it feasible to maintain libraries of test data by optimizing storage use and enabling fast retrieval. Data libraries should be automatically version-controlled in the same way that tools like Git exist for code versioning.
Contention Reduction
At most IT organizations, data access is serialized due to contention in shared software testing environments during working hours. Paradoxically, environments are often underutilized across the entire testing process because systems are left running when not used because of the time to populate a new environment with configurations and test data. A modern test data strategy should enable the ephemeral use of instantly accessible data from any point in time.
Ephemeral Data Environments
Users should be able to bookmark data, tear down infrastructure environments, and redeploy a new data environment populated by a bookmark in minutes using their test data management tools. This eliminates shared resource contention during peak times, leverages automation to free up resources during off peak times, and enables the parallelization of individual data sandbox environments.
An optimized test data strategy can eliminate contention while achieving up to 50% higher utilization of resources.
The Modern Approach to Test Data Management Strategy
By using a modern DevOps test data management approach, organizations can transform how teams manage and consume appropriate test data. IT operations can mask and deliver data one hundred times faster while using ten times less space. The net result? More projects can be completed in less time using less infrastructure.
- Faster release cycles and time-to-market: 3.5 days to refresh an environment vs. 10 minutes via self-service
- Higher quality releases and reduced cost: 15% vs. 0% data-related defects
- Ensured data privacy and regulatory compliance: data secured in non-production
