In the quest to improve the efficiency of their products and satisfy a tech-savvy population that is always asking for more, software developers are working harder than ever before. The result is increased complexity and intertwining of applications together with numerous devices and platforms. Therefore, there is an increasing need for stronger system integration testing methods which is intended to ensure proper interactions between different components that make up a software system.
There are various different ways of achieving application quality assurance. They usually involve many processes ranging from testing of individual modules to specialized software testing forms such as performance and security. In addition, there is integration testing which ensures that an entire system has met specified requirements and can, therefore, operate successfully in the environment it is intended for.
Functional Software Testing
There are various stages of functional testing. In unit testing, individual software components of an application are tested. On the other hand, system integration testing ensures that components that have already passed through unit testing can perform certain tasks when brought together.
After system integration testing, the entire system is tested for bugs and errors. This is known as system testing. Software and hardware components of the entire system are interfaced before they are tested as a whole to ensure that they meet the user’s expectation and working conditions.
The final part of functional software testing is known as acceptance testing. The aim of conducting it is making sure that all requirements of the product’s project have been met. The end users ensure that the system works according to their expectations.
Performance, Load and Stress Software Testing
Performance testing involves many processes intended to meet different requirements. For instance, software may be tested to determine how it behaves when it subjected to an increasing load. The aim is to ensure that the system can perform efficiently at given response times when under its expected load. Stress testing involves determining the point at which the system fails when subjected to excess load.
When a system is tested for security and vulnerability, the aim is usually to ensure that it meets confidentially, authentication, integration non-repudiation and availability. On the other hand, usability testing seeks to look at the interests of the end-user. It involves ensuring ease of accessibility of product forms, including efficiency, memorability, learnability, satisfaction and errors. Compatibility testing ensures that the application is compatible with certain operating systems, web browsers, mobile devices, hardware platforms and other programs.
With increased innovation efforts in the software development industry, system integration testing has become as important as the software itself. When conducting software testing, you should ensure that you have the right Detail Design document which clearly details interactions between each unit. In addition, use automated testing whenever it is possible. For those of you interested, there is more information available at QA Consultants.
