What is test data management and why is it important?

Test data management (TDM) is an important aspect of software testing, and involves generating and managing the data that is used in the testing process. It’s important that software quality teams do not use production data as a part of the testing process because production data often includes confidential and/or privileged data that is protected by regulations such as GDPR, HIPAA, PCI, or other data privacy focused policies. That being said, to ensure that software functions as designed, it’s important to test with data that is as similar to production data as possible. This is where TDM comes into play.

What are the various approaches to TDM?

There are several approaches to test data management that are designed to ensure the data used in software testing is similar to production data. These include:

• Synthetic data generation: Synthetic data generation is an approach that has become popular in recent years. It involves creating synthetic data that is similar to production data in format and value. The key advantages of synthetic data generation are that it provides non-production test data and usually does not require significant data storage. 
• Data masking: Data masking is an approach that takes a copy of production data, then masks the sensitive data values. Masking means to replace the identified sensitive data with different values that are similarly structured (i.e., date, currency, name, etc.).
• Data subsetting: Data subsetting is the process of taking a subset of production data.  Many production databases can be very large and subsetting helps to reduce data storage costs while still capturing production data. Masking can then be subsequently applied to data subsets. 
• Data virtualization: Similar to a hypervisor for an OS, data virtualization is the process of virtualizing a database for test data. Generally, data virtualization solutions are used to help enable lower data storage costs. Data can then subsequently be masked in the virtualized database.

Challenges related to test data management today

Test data management is more challenge today due to the increasing complexity of software applications, regulations related to data privacy, and the need to enable continuous testing as a part of accelerated software delivery. As software applications become more complex, the amount of data required to test them grows exponentially. Additionally, the frequency of software updates and releases has increased, making it challenging to ensure that testing is comprehensive and thorough.

Effective test data management is critical to ensure that tests are accurate, efficient, and reliable. If test data is not managed properly, it can lead to inaccurate test results, wasted time and resources, and missed defects. Inaccurate test results can lead to false positives or false negatives, which can be costly for businesses and may result in delays in software releases.        
 

Furthermore, the General Data Protection Regulation (GDPR) and other data protection laws require organizations to ensure that personal data is used and protected appropriately. This means that test data used in software testing must be anonymized and not contain any personal identifiable information (PII). Managing and anonymizing test data can be time-consuming and challenging, and requires a robust test data management solution.

Benefits of TDM

Testing accuracy:

Test data is used to simulate real-world scenarios, and inaccurate or incomplete test data can lead to unreliable test results. By managing test data effectively, testers can ensure that test data is accurate and up to date, leading to more reliable testing results.

Testing efficiency:

A solid approach to test data management and test data tools can help testers save time and effort by providing a platform for organizing and categorizing test data sets. This makes it easier to select and use the appropriate test data sets, reducing the time needed for test data preparation and ensuring that testers can focus on actual testing.

Compliance with regulations:

Many industries are subject to regulations around data privacy and security, and test data is no exception. Sensitive production data should never be used in non-production environments. Test data management can ensure that test data is properly masked and anonymous, complying with data privacy regulations. Various countries across the globe have implemented strict regulations in relation to data and how it's consumed. Hence it is really important to ensure TDM is part of a longer term strategy of enterprise organizations.

Cost-effectiveness:

Effective test data management can also save costs in the long run. With proper management, testers can reuse test data sets, reducing the need for generating new test data for each test cycle. This can save both time and resources, ultimately leading to cost savings.

Improved testing coverage:

With effective test data management, testers can generate test data for a wide range of scenarios and edge cases, ensuring that the application is thoroughly tested. This leads to higher testing coverage and ultimately, higher quality software.

How does the likes of ChatGPT help the future of TDM?

• Test case generation: ChatGPT can be used to generate test cases based on specific requirements or user stories. By inputting a description of the desired functionality, ChatGPT can generate test cases that cover different scenarios and edge cases.

// Import necessary packages

import com.kms.katalon.core.testdata.TestDataFactory as TestDataFactory

// Create test data object

TestDataFactory testDataFactory = new TestDataFactory()

// Get the test data set

def testData = testDataFactory.findTestData('Test Data File Name')

// Navigate to the website

WebUI.navigateToUrl('https://www.example.com')

// Loop through each test data row

for (def index = 1; index <= testData.getRowNumbers(); index++) {

    // Get the test data values

    def firstName = testData.getValue(index, 'First Name')

    def lastName = testData.getValue(index, 'Last Name')

    def email = testData.getValue(index, 'Email')

    def password = testData.getValue(index, 'Password')

    // Enter the test data values into the form fields

    WebUI.sendKeys(findTestObject('First Name Field'), firstName)

    WebUI.sendKeys(findTestObject('Last Name Field'), lastName)

    WebUI.sendKeys(findTestObject('Email Field'), email)

    WebUI.sendKeys(findTestObject('Password Field'), password)

    // Click the submit button

    WebUI.click(findTestObject('Submit Button'))

    // Verify that the user is redirected to a success page

    WebUI.verifyElementPresent(findTestObject('Success Page'))

    // Clear the form fields for the next test data set

    WebUI.clearText(findTestObject('First Name Field'))

    WebUI.clearText(findTestObject('Last Name Field'))

    WebUI.clearText(findTestObject('Email Field'))

    WebUI.clearText(findTestObject('Password Field'))

}

In this test case, we are using a test data file to store different test data sets. We loop through each row in the test data file and use the test data values to fill out the form fields on the website. We then click the submit button and verify that the user is redirected to a success page. This test case can be expanded by adding more test data rows to cover a wider range of scenarios.

• Natural language processing: ChatGPT can be used to understand natural language and generate test data based on user input. By inputting a natural language description of a test scenario, ChatGPT can generate relevant test data sets.

This CSV file includes a sample of 10 home addresses in different states across the USA along with their corresponding zip codes. This test data can be used to test applications that require the input of a user's address, such as online shopping websites, delivery services, or mapping applications. You can add more rows to this CSV file to create a larger dataset for your testing needs.

While ChatGPT may not be specifically designed for test data generation, it can provide assistance in generating test data and improving the overall quality of automation testing.

Test data management is an important aspect of automation testing, and as automation testing tools continue to develop, we can expect to see more advanced and flexible test data management features. These features will ultimately lead to higher quality software and better testing coverage.
