Volume Testing in Software Testing: Definition & Examples

Since no testing activities, other than volume tests, check the ability of the system to process large data pools, there’s no reasonable way for teams to skip volume testing. If undetected, issues like data processing and storage issues can lead to security jeopardy or system shutdown.

This post provides business managers, developers, and beginner testers with an understanding of the volume testing, the objectives it helps accomplish, its best practices, and challenges to take into account when preparing for testing sessions. 

What Is Volume Testing

Volume testing definition refers to validating the performance of the software when it processes large data volumes. Volume testing is also a subset of comparative software load testing. The benchmark test is carried out based on the current data volume (usually corresponding to the current filling of the industrial environment). Then, a team of quality assurance in software testing performs a different test, after filling the database so that it corresponds the forecasted values. Volume testing can be both short-term and long-term.

The Objectives of Volume Testing

Volume tests cover a wide range of operations and infrastructure components — databases, online systems, file exchanges, file systems, and system memory. In addition to traditional volume testing, using an API load testing tool can help teams validate API performance under increased data loads, ensuring that all system components work in harmony. Validating such a wide range of elements helps testers achieve the following objectives.

Challenges in Volume Testing

All the major considerations in volume testing have to do with data. This is why there are a few things to always keep in mind when starting a volume testing. 

Differences Between Load Testing and Volume Testing

Despite rather clear differences between load and volume testing, it’s common for business managers and beginner QA testers to confuse the two. First things first, take a look at the definition of each term:

Thus, the type of test data, as well as the range of use cases for testing, are different for load testing vs volume testing. To get a better understanding of the differences between the two, take a look at the table below:

Volume Testing Examples in Real life

To get a better understanding of the use of volume testing for websites, apps, and web application projects, here are a few volume testing examples that illustrate how it is used in real life. 

Conclusion

Volume testing prepares the system for dealing with extreme data loads (e.g. when a set of branches are attached to the system). No other type of testing can replace the insights volume testing provides project teams and testers with. 

To make sure your product is well-protected from data-volume-induced downtimes and crashes, request a team of QA professionals, with a ready-to-deploy volume testing checklist.
