How Test Data Management Supports Your Scaling Organization: Solutions, Use Cases, & Benefits

Efficient test data management is a critical component of modern software development. With the demand for quality applications growing rapidly, managing and provisioning test data has become more challenging.  

Recently, I’ve noticed organizations have pockets that perform some test data management practices very well. Whether the CISO has flagged a particular application or a data engineer has taken it upon themselves to pioneer a new approach, you see spurts of strong practices. However, they are frequently on different teams, do not share strategies, and ultimately leave themselves exposed to data leak risk and generate high infrastructure costs. These organizations recognize they would benefit from a centralized test data management strategy, but they aren’t sure where to get started. 

In this blog, I’ll explore the essentials of test data management, highlight its importance for DevOps initiatives, and discuss ways to overcome common challenges.  

What is Test Data Management?

Test data management is the process for providing controlled data access to modern teams throughout the software development lifecycle (SDLC).After talking with customers, I’ve noticed this requirement always spans more than one type of data: 

• Location: On-premises vs. Cloud (AWS, Azure, GCP, etc) 
• Type: Oracle, SQL Server, PostgreSQL, MongoDB, etc. 
• Purpose: AppDev, Data Analytics, and LLM Training 

Rarely does an organization only manage one type of data. However, the limitations of homegrown solutions often pigeonhole capabilities and prevent organizations from taking full advantage of their data. With effective test data management strategies, teams gain access to the permitted data they need on demand. 

See my colleague Vikram Kulkarni explain test data management in 5 minutes:

Common Types of Test Data 

There are four common ways to create test data for application development teams and testing teams in the SDLC. 

Production Data 

Real data from production environments provide the most complete test coverage, but can add friction without modern DevOps test data management tooling because of security controls around sensitive data. On top of that, moving multitudes of data can result in higher costs and slower speeds. Your production data isn’t as useful if it’s delivered two weeks late. 

Data Subsets 

Test data subsets can improve static test performance while providing some saving on compute, storage, and software licensing costs. However, subsets do not provide sufficient test coverage for application completeness or integration testing needs. Subsets intrinsically omit test cases and contains sensitive values because it's still a direct copy of production values. 

Masked Data 

Production data obfuscation using masking techniques helps teams leverage existing data in a compliant manner to quickly provision test data that meets regulatory requirements such as PCI, HIPAA, and GDPR. 

It’s important that I note the different kinds of data masking — such as dynamic and static data masking. Dynamic masking will simply omit the data, replacing the data values with asterisks or Xs, but it maintains the sensitive behind the scenes. For example, a Social Security Number might appear as XXX-XX-XXXX, which is not useful from a testing perspective and permits reidentification of the data.  

Delphix uses static data masking. Static masking takes all the data from production, leverages algorithms to identify sensitive data, applies PII data masking to sensitive fields while keeping only relevant data for testing. This enables test data provisioning of realistic values without introducing unsafe levels of risk. Static data masking is irreversible, ensuring high-quality data privacy and security. 

Synthetic Data Generation 

Synthetic test data intrinsically contains no personally identifiable or sensitive information. This makes synthetic data creation an appealing choice for initial prototyping of new features or model exploration of test data sets.  

Generated synthetic data can use algorithms to ensure that it remains realistic and hasreferential integrity. This synthetic data can supplement masked data, for well-rounded test data management.  While it’s not fit for certain use cases like debugging, synthetic data generation is useful for improving end-to-end testing quality. 

Combination 

Often, companies use all of the above methods. Leveraging a combination of these can help your company effectively meet its test data management needs. Our 2025 State of Data Compliance and Security Report found that 95% of surveyed organizations use static masking, 76% use dynamic, and 63% use synthetic data. 

Here are some example scenarios of why your company may need multiple methods: 

• Your app teams use a full copy of masked production, but because each member wants their own copy, you need to subset to make the costs work.  
• Your app teams are developing a new feature but want to make sure it’s backwards compatible, so they’ll take masked data and synthetically add additional information to it. 
• You already have a synthetic dataset, but you only need the first 100 values, not all 500,000.  

Why is Test Data Management Important?

Test data management is important because as your various types of test data are curated for different application and team needs, you must have a way to manage it all. Test data management involves the synchronization of multiple data sources from production, versioning copies, sensitive data discovery, masking sensitive data, and multicloud distribution of test data to support agile development and automated testing.  

Modern test data management solutions help organizations accelerate application development speed, code quality, data compliance, and sustainability initiatives by providing timely access to fresh relevant data downstream for code development, automated tests, troubleshooting, and validation.

Common Test Data Management Challenges 

Application development teams need fast, reliable test data but are constrained by the speed, quality, security, and costs of moving data to environments during the software development lifecycle (SDLC). Below are the most common challenges that organizations face when it comes to managing test data. 

Handling Sensitive Data 

Organizations often struggle to quickly meet compliance and data privacy regulations at test data provisioning, while also reducing data friction for AppDev and software test teams. A test data management tool helps CIOs and CISOs to administer security controls such as data masking, authorization, authentication, fine-grained data access management, and audits logs in downstream environments as part of test data management processes. 

Slow, Manual, High-Touch Provisioning 

Test environment provisioning is a slow, manual, and high-touch process. Most IT organizations rely on a request-fulfill model, in which developers and testers find their requests queued behind others. Because it takes significant time and effort to create test data, it can take days, or even weeks to provision updated data for an environment. 

Often, the time to turn around a new environment is directly correlated to how many people are involved in the process. Enterprises typically have four or more administrators involved in setting up and provisioning data for a non-production environment. Not only does this process place a strain on operations teams, but it also creates time sinks during test cyclesand slows the pace of application delivery. 

Lack of High-Fidelity Data 

Development teams often lack access to test data that is fit for purpose. For example, depending on the release version being tested, a developer might require a data set as of a specific point in time.  

But all too often, they are forced to work with a stale copy of data due to the complexity of refreshing an environment. This can result in lost productivity due to time spent resolving data-related issues and increases the risk of data-related defects escaping into production. 

Friction in Release Cycles 

For many applications, such as those processing credit card numbers, patient records, or other sensitive information, static data masking is critical to ensuring regulatory compliance and protecting against data breaches. 

According to IBM and the Ponemon Institute, the cost of a data breach averages $4.4million. However, masking sensitive data often adds operational overhead. An end-to-end masking process may take an entire week because of complexity for managing referential integrity across multiple tables and databases. 

Rising Storage Costs 

IT organizations create multiple, redundant copies of test data, resulting in inefficient use of storage. To meet concurrent demands within the confines of storage capacity, operations teams must coordinate test data availability across multiple teams, applications, and release versions. As a result, development teams often contend for limited, shared environments, resulting in the serialization of critical application projects. 

Regardless of your challenge, adopting test data management best practices can offer a path forward.

Improved Application and Software Quality 

Teams getting the right data at the right time is a classic shift-left strategy. With data on-demand, they’ll be able to create higher quality applications and software. Otherwise, engineers will use aged test data, inaccurate self-generated data, or worse, no data at all. Effective test data management ensures that data is timely, realistic, and compliant, which helps keep your engineers focused on the task at hand, without context switching. With Delphix, companies can also develop applications 58% more quickly.
