In Computer Science, the concept of robustness testing implies verification of whether a computer application produces unacceptable error conditions. For the robustness test fuzz testing is a technique which is related to any software application; this application is crumbling to verify whether any memory leak or whether the system is random, is a way to inject unexpected input values. Sometimes inputs reflect certain behaviors that lead to some unexpected consequences that can lead our attention to some new directions that can help us discover a new dimension.
The term ‘robust’ is synonymous with strength. So robustness testing is the way to assess the quality of a software product. It the process of verifying whether a software system performs well under stress conditions or not.
The method of performing robustness testing follows a number of conventions. A number of invalid entries or strange / stressful environments were created. Sometimes it happens that the program can crash when certain inputs are provided. It becomes important to catch these errors and correct them according to the specifications of the requirement.
Therefore, appropriate test scenarios are developed for testing in an appropriate test environment.
- Interface robustness testing: This method relies on the fact that if a software product performs exceptionally well, that is, it does not crash in any scenarios, it means that it has passed the robustness criteria.
- Dependability benchmarking: Aims to detect the dependability of a software component or the system on the software and hardware .
Why Robustness Testing Important?
Robustness testing ensures that a software system qualifies as the end product for which it is intended, and therefore serves the right purpose. Since we know that a complete software system consists of several components, such testing ensures that the cost and time required to deliver a software system efficiently is reduced.
Therefore, the robustness test is somehow performed as follows-a combination of valid and invalid entries are transmitted to the system and checked for performance. Thus, a system is tested and verified under different conditions.
Challenges in Robustness Testing
It is a common phenomenon that a task needs to be carried out in a stipulated period of time. The same applies to robustness testing. As it’s the end phase of the testing process, software testers are burdened with the task of conducting the test plans within a limited time span. So testers have to take special care to the choice of test cases, that is, it must not be repetitive and must serve a productive output.
Hence the execution of test cases must be wisely planned in accordance.
- The key challenge with an automation tool is that they are designed for some specific purpose, hence lack flexibility
- Due to lack of adaptiveness of the systems, the effort to apply the principle of redundancy in order to structure it as per the need of the current requirement. But one needs to be careful enough to make changes to the code being applied, as per a given set of requirement.
- Even if the logic applied to the new piece of code is correct, complexity gets added with time as the size of a project keeps expanding.
Benefits Of Robustness Testing
Various business organizations use robustness testing for benefits for their projects such as:
- Better project analysis: before a specific design is completed, all available data in the analysis phase is reviewed to make it more effective and useful. The robust analysis phase will carry out quality control if a particular idea is good enough to move on to the next phase.
- Better design: if a robust analysis test is performed before any design is completed, it will certainly give a better result and better design options.
