Test documentation provides a clear path for all team members to navigate through the process. This reduces the amount of time spent on resolving issues caused by miscommunication or missing documentation.

It’s also important to note that testing documentation should be regularly pruned for relevancy. Documentation that is too comprehensive becomes unwieldy and less helpful to the testing process.

Test Data Requirements

There are many types of test data management required by software applications. Some are needed for testing all code paths, others are needed to uncover security vulnerabilities and other issues. Tests must be designed in advance for proper test data management, or the results will likely not be accurate enough to uncover defects and provide reliable testing and deployment results.

The test data may be created or obtained from various sources, including real data from production systems with masked personal information. This is typically the best option because it ensures that the application will be tested in a real environment, while also ensuring that sensitive or personally identifiable data is not compromised during testing.

Other kinds of test data include boundary value test data, which consists of borderline values that may be passed to the application in order to ensure that it does not exceed hard boundaries. Equivalence partition test data, decision table test data and state transition test data are other forms of test data that may be used.

Test Data Creation

Once a test case has been scripted, the actual test data needs to be created or obtained. This can be done in a few ways, including synthetically creating data sets, using real-world data from production systems (with proper security and privacy controls in place), or manually copying existing data from a database.

A good test data management process can result in optimal test coverage, reduced costs as a result of early bug-detection and improved results. However, to realize these benefits, the quality of your test data must be high.

For this reason, it is important to regularly audit your test data to make sure it meets your application’s specific requirements. For example, if you’re using test data that contains personally identifiable information (PII), you must use masking techniques to make it unidentifiable before use in your testing. You should also create data sets that cover all of the possible code paths and boundary value conditions.

Test Data Repository

Test data documentation serves two key purposes – it enables testers to plan and execute their tests reliably and it updates connected project participants, like design teams and business owners on the progress of the product. QA specialists may recommend clients to create this type of documentation but ultimately it is a decision the client makes.

Test Data Management (TDM) refers to a system that provides testers with an optimum mix of production-mapped data and synthetic data in a central repository. This is achieved through a combination of API integrations, data migration and lookup table extractions.

Typically the voluminous data leveraged for testing software applications includes login details like usernames and passwords, transaction details, fake pictures, statistics and media content. Managing this data is a challenge due to data privacy regulations and as such, it is imperative that all PII be discovered and masked. This can be time consuming and labor-intensive for data teams.

Test Data Maintenance

The process of locating and collecting test data within the stipulated time is an essential component of the entire testing process. It requires efficient methodologies and tools to effectively generate, provision, and manage reusable test data. This helps to save costs, reduce efforts, boost the overall effectiveness of testing operations.

Effective test data management tools also involves ensuring that the relevant data is available at all times. This involves a regular data refresh cycle as well as a clear process to determine when the test data should be deemed obsolete or redundant.

Ineffective or faulty test data sets can significantly hamper the quality of an application. It can lead to ineffective or incomplete tests and delays in bug detection which eventually leads to higher repair costs. However, with the right test data management processes in place, it can help create better quality software that perform reliably on deployment and lowers costs through early bug-detection. This ultimately results in a cost-efficient and seamless software deployment process.
