How to Develop a Test Data Management Strategy?

Every day, new apps are launched in the market. Some of them become popular and successful, while others are ignored and forgotten. What makes the difference? One of the key factors is the quality of the test data used to develop and test the apps.

Test data is crucial to use realistic and relevant test data in the early stages of app design and also in the final stages of app testing.

At this phase, effective test data management (TDM) strategy plays an important role. Test data management is the process of creating, storing, updating, and using test data for app development and testing. It helps to ensure the accuracy, reliability, and security of the test data.

So, teams must have a clear goal for their test data when using a test data management platform or software. This will help them make the best decision on the basis of the results.

At research firm Gartner, the famous analyst Jim Scheibmeir says, “To create a better strategy, product and platform engineering teams should have a strong collaboration. They should be clear about their testing goal. For example, they are using it to test the performance or functional characteristics of the software.”

Well, there is much more to know in this article. We’ll discuss the meaning of TDM, the best practices to develop this strategy, and what industries can benefit from it.

Why is test data important for modern digital systems?

Test data is very important for modern digital systems. Why? Because more and more businesses use digital channels to run their operations. They want to give their customers a smooth and satisfying experience.

To do that, they need to make sure their apps work well and don’t have any bugs. That’s why they need to do QA inspections. QA inspections check the quality of the apps by testing them with different scenarios. But to test the apps properly, they need to have good test data.

Plus, it is crucial to have test data management because it helps to cover all the testing areas and find any errors or issues. TDM also needs to have a large volume and diversity of test data. This is because the apps need to handle different types of data and users. The more test scenarios there are, the more test data there will be.

In a few terms, test data is the driving force behind the advancement of test data management strategies. It helps to increase the quality and performance of the apps and the customer experience.

What does Test Data Management mean?

Simply put, test data management means organizing and handling the data used for testing software. It makes sure that you have the right data in the right format and amount when needed for testing. So, it’s like keeping your testing materials organized and ready to use whenever you need them.

Test data management solutions help you avoid errors and delays in your testing process. The best part? You can use it for automated testing, especially when you test the whole system.

But also remember that different tests need different kinds of data. For example, you may need data from different sources or locations. The quality of your test data is very important. It should be realistic, accurate, and up-to-date. Moreover, it should follow the rules and regulations of your industry. TDM can help you achieve these goals and improve your testing outcomes.

What industries can benefit the utmost from TDM solutions?

There are many industries and companies that can gain big benefits from TDM, such as:

Energy and Utilities

TDM can help energy and utilities companies to manage their data better. They can use it to extract valuable insights from their data, such as energy consumption patterns, customer behavior, and market trends. This can help them to improve their efficiency, reduce costs, and comply with regulations.

Media and Entertainment

Furthermore, effective TDM can help media and entertainment companies to create more engaging and personalized content for their audiences. They can use TDM to analyze their data, such as user preferences, feedback, and ratings. This can help them to optimize their content delivery, increase their revenue, and protect their intellectual property.

Education

Education institutions can also take huge benefits from test data management solutions to enhance their teaching and learning outcomes. For example, they can use TDM to access and organize their data, such as course materials, student records, and research papers. This can help them to provide more interactive and customized learning experiences.

Last but not least, test data management can boost the retail industry by optimizing data management and analytics. They can help retailers to understand customer behavior and preferences. This way, the industry creates personalized and engaging customer experiences by delivering relevant and timely offers and recommendations.

What are the methods to develop a test data management strategy?

Here are some main test data management best practices that can enhance the quality of your testing:

1. Establish a Test Data Management Strategy

A good TDM strategy is very important for software testing. It helps you create, provide, anonymize, and maintain the data you need for testing.

The strategy includes collaboration between data management experts, developers, and testing teams. This ensures that test data is of high quality and secure, as well as matches real situations and test needs. This way, you can test your software better and faster.

2. Create a robust Data Discovery Process

Data discovery is a key step in testing. It helps you find out what data you need for each test case. This step includes understanding how your application uses data from different sources and types.

Data discovery helps you choose the right test data for your scenarios. You should make sure that your test data is similar to your real data. This way, you can test your application in a realistic way.

3. Regularly refresh Test Data

Refreshing test data regularly is very important for data accuracy and relevance. If you use outdated or stale test data, you may face some risks.

For example, you may miss some critical defects or get invalid test results. That can affect the quality of your software product. So, to avoid these risks, testing teams should refresh test data often.

This way, you can ensure that your test data is realistic and up-to-date. It’s all about finding and fixing the bugs or errors more easily.

4. Develop a Review and Auditing Process

When employing TDM strategies, you also need to follow the data privacy rules. How can you do that? By developing a review and auditing process.

This process has two parts: regular reviews and internal audits. The reviews are done by the people who use the test data. They check if the data is correct and up to date.

The audits are done by the people who manage the test data. They check if the data is secure and compliant. This process helps you keep the data integrity high.

5. Ensure Data security

Data security is of significant importance in test data management. You need to protect your data from hackers and leaks. For that, you can use these strategies to keep your data safe:

Data masking: This means hiding some parts of your data with fake or random values.

Encryption: This means changing your data into a secret code that only you can read.

Access controls: This means setting rules and permissions for who can access your data and how.

The goals of data security are to protect sensitive information and prevent unauthorized access.

So, you should apply security measures to limit access to your data. Only authorized people should be able to access your data. This way, you can ensure the confidentiality and integrity of your data during testing.

6. Make Use of Automation where possible

Automation is a great way to manage your test data. It can make your work faster and more accurate.

Using automation tools, you can automate tasks like creating test data, refreshing test environments, and hiding sensitive data.

These tools can do these tasks in a snap. This way, you can focus more on the testing process and less on the manual work.

7. Leverage Reliable Test Data Management Tools

To manage your test data well, you need effective tools. These tools help you simplify the process of creating and using test data. They also offer key features that make your test data more reliable and reusable.

For example, you can use data versioning to track changes in your test data. Plus, you can use data cloning to copy your test data without affecting the original. Moreover, you can use data subset generation to create smaller sets of test data for specific tests.

These features help you streamline your test data management process. With effective TDM tools, you can save time, money, and resources.
