This article highlights critical information about software system testing for programmers. Testing activities which are done to check the functionality of a fully integrated software is known as software system testing. It is done to validate the status and correct working of the internal components of the system. A testing method is required to check the execution of current software with external components.
System testing is used to check the following scenarios for the project:
System testing is performed by creating detailed test cases and test suites to understand each application from the user perspective. Testers uses an effective test plan software to track any changes in test cases and their requirements. Test plan tool also helps in finding and monitoring bugs.
What are the various types of system testing?
The various types of system testing performed in an application software by large software development companies are:
Usability testing
This type of testing is used to test the user’s interaction with the application. The tester checks the flexibility and output of the system of the application in handling the system’s objective.
Load Testing
As the name depicts, this form of testing checks the application capability to handle real-time stress and load. The ability of the system to withstand the load and produce expected results is critical to release successful software.
Regression Testing
This form of testing is essential to check and validate the changes in new modules and their impact on existing modules. Regression testing prevents software failures by testing the newly implemented changes and ensures no errors reappears with time.
Recovery Testing
This form of testing is used to evaluate the software under development is reliable, trustworthy, successful, and a quick recovery from any crashes is possible. This form of testing also ensures system integrity and data safety.
Migration Testing
This form of testing is done to check the compatibility of software under development for older infrastructure or system specification. The software should run smoothly on all kinds of platforms to cater to a wide range of end-users.
Functional Testing
This form of testing checks the complete functions to find the missing ones. The check is done to keep track of functionalities as per client requirements. This testing method also gives the list of additional features to be included in the software to improve results.
Hardware Testing
This form of testing checks software and its smooth interaction between hardware and software components. This testing reduces any chances of the error caused due to hardware and software issues. Software system testing is performed on the complete product.
The entire software is divided into several modules, and each module is tested right after development. Software system testing checks the software when all the modules are combined into one standalone software ready for delivery. It is the last testing performed on the software to check any integration issues or errors.
Conclusion
Software system testing is performed to check a software whether it meets the user goals or not. The main focus of this testing is to ensure the complete system works perfectly in all the scenarios. This system unit testing releases high performing software.
