7 best practices for streamlining test data management

6 best practices for streamlining test data management

Developers utilize test data to check and improve program functioning. This may include standard or essential user flow testing and altering any defects in the system.

In the data testing process, application programming interfaces are required to interchange electronic data in real-time seamlessly.

This occurs even when engaging with APIs from many suppliers and partners.

DevOps and quality assurance teams frequently wait for test data from data sources when doing integration and API testing. This often results in delays — which might affect the sprint or the overall delivery of the program.

To avoid application testing delays, you must have instant access to real test data via test data management (TDM).

Test data management allows you to develop and manage safe and permitted datasets that your firm may utilize across many teams. You can also use TDM to validate a software application’s functioning.

Challenges in managing test data

Handling test data management processes can be challenging for businesses. Resolving these difficulties is crucial to ensuring the quality of the software development life cycle.

The following are some of the common test data challenges businesses face:

Data privacy and security concerns

Data privacy and security are among the greatest obstacles in the entire testing process. Test data might compromise confidential information, which must be protected from unauthorized access.


Organizations must ensure testing data is inaccessible to unauthorized parties to avoid data intrusions and other security risks.

Organizations can protect sensitive data by using data masking and obfuscation techniques. The test data management team must also implement access limitations for non-members and activate history to view who recently accessed these records.

Lack of data availability

Another problem in handling test data is the lack or total absence of required data. Test data must be available when needed, and delays in receiving the information might disrupt the process.

This might cause software development and testing delays, lowering overall product quality.


Organizations must use a reliable test data management tool to produce the appropriate data sets needed. They can also employ data versioning and tracking to guarantee that the information used for software testing is always up-to-date and correct.

Data quality issues

Poor data quality can lead to inaccurate test results and influence the overall product quality.

As mentioned, test data management must ensure that the gathered data meets quality testing results. Businesses must also guarantee that testing data is trustworthy and representative of real-world occurrences.

Challenges in managing test data


Use data profiling and analysis tools to examine test data and identify any issues that must be solved to address data quality concerns.

Organizations can also utilize test data management tools to generate synthetic test data sets that mimic real-world circumstances.

Sensitive data

Managing test data involves handling sensitive information. Protecting records, such as personal information or proprietary business details, is critical to complying with privacy regulations and maintaining user trust.


For better test data coverage, implement robust data masking, encryption, and anonymization techniques to ensure that test environments do not inadvertently expose or misuse sensitive data.

Additionally, handling sensitive data necessitates stringent access controls and thorough auditing processes to prevent unauthorized access and data breaches.

Data complexity

Diverse test datasets can be difficult to read and organize.

Real-world occurrences must be reflected in the testing data, which may necessitate the usage of simple data structures to comprehend and file easily.


Organizations can employ test data management solutions that can handle complex data structures to overcome difficulties with data complexity.

Firms can also use data profiling and analysis tools to find any problems with the test data sets and ensure they are accurate and indicative of real-world circumstances.

Cost of managing production data

Finding problems with the test data sets entails employing open-source test data management tools, which can be expensive. Companies must ensure they are using the most economical methods of test data management.


Businesses can use data masking and obfuscation techniques to lessen the risk of data breaches and other security problems and address the expense of handling test data.

To verify that the test data used for software testing is current and accurate, they may also utilize data versioning and tracking, which can help lower the testing cost.

Test data management: 7 best practices and examples

Some of the abovementioned solutions for the challenges in test data management are further explained as best practices below:

1. Data profiling and analysis

Data profiling and analysis are critical components of test data management that entail evaluating test data to find patterns and trends. This assists companies in understanding the quality of the data and identifying any issues that require attention.

Organizations can use data profiling technologies to find duplicate data, missing data, and data discrepancies.

An organization, for instance, can utilize data profiling technologies to detect patterns in consumer data such as age, gender, and geography.

This can assist businesses in understanding their clients’ demographics and building test data sets typical of real-world circumstances.

Companies can also utilize data profiling to discover missing or inconsistent data, which can help improve the quality of testing data.

As a result, the test data management team can guarantee that the test data used for software testing is high quality.

Further, data profiling and analysis can assist DevOps and software development teams in identifying software issues earlier in the testing process.

2. Data masking and data obfuscation

Data masking and obfuscation are essential for safeguarding sensitive data in test data sets. This assures that the testing data is safe and does not include sensitive information.

An enterprise, for example, can employ data masking techniques to conceal social security numbers, credit card numbers, and other sensitive information.

On the other hand, data obfuscation transforms data into a different form but with the same content to protect it.

This method is useful in financial institutions or retail businesses that accept credit card payments without revealing the actual data to a third-party processor.

As a result, organizations may guarantee that the test data used for software testing is safe and does not contain sensitive information that could be used for harmful reasons.
