Software Testing - Non-functional Testing
Software testing ensures that the software is working properly as per the functional and non-functional specifications. Non-functional testing is done to test if the software is built as per its non-functional specifications, and requirements.
What is Software Non-Functional Testing?
The software non-functional testing is performed to test all the non-functional features, and aspects. It verifies if the robustness, and performance of the software is as per its non-functional requirements(which are not covered by the functional testing). The non-functional testing is as important as the functional testing of the software.
Objectives of Software Non-Functional Testing
The objectives of the software non-functional testing are listed below −
- The software non-functional testing is done to increase the softwares portability, maintainability, usability, portability etc.
- The software non-functional testing reduces the probability of finding non-functional defects in the production.
- The software non-functional testing reduces the cost incurred to resolve the non-functional bugs in the software.
- The software non-functional testing improves the process of execution, set up, installation, and analyzing the working of the software.
- The software non-functional testing gathers information, measurements, and metrics to take up future research and development activities.
- The software non-functional testing enhances the overall knowledge, and expertise over the software.
Different Techniques of Software Non-Functional Testing
The different techniques of the software non-functional testing are listed below −
Compatibility Testing − This type of testing is done to check if the software is compatible with other software.
Compliance Testing − This type of testing is done to check if the software meets particular compliances namely HIPAA etc.
Endurance Testing − This type of testing is done to check if the software can withstand load for an extended period of time.
Load Testing − This type of testing is done to check if the software can handle a large chunk of data, and transactions.
Performance Testing − This type of testing is done to check if the software is able to work as per its performance requirements.
Recovery Testing − This type of testing is done to check if the software can recover from crash, failure, data loss etc.
Security Testing − This type of testing is done to check if the software can handle unauthorized access, and other security vulnerabilities.
Scalability Testing − This type of testing is done to check if the software can be scaled down or up as per the requirements.
Stress Testing − This type of testing is done to check if the software can handle abnormal load.
Usability Testing − This type of testing is done to check if the software can be navigated easily by the users.
Volume − This type of testing is done to check if the software has a big volume of data.
Failover Testing − This type of testing is done to check if the software has enough resources allocated during recovery from a failure.
Portability Testing − This type of testing is done to check if the software can be shifted from one environment to another.
Reliability Testing − This type of testing is done to check if the software can work without any errors for a certain period of time under specific circumstances.
Baseline Testing − This type of testing is done to check if the software has undergone degradation after a certain period of time.
Documentation Testing − This type of testing is done to check if the documents pertaining to the software are correct.
Localization Testing − This type of testing is done to verify the performance, and quality of the software for a particular culture so that it works well for the foreign users.
Internationalization Testing − This type of testing is done to verify the adaptability of the software to various cultures, and languages without requiring any code changes.
