Software quality is paramount; however, in the haste of software release into the market this parameter used to be often compromised on by most of the enterprises until sometime back. Times have changed and so has the perception of the global enterprise community. It is clearly understood now that software quality cannot be overlooked under any circumstances. It's when the role of functional testing services comes to the forefront.
To ensure that all the specified functional needs are addressed adequately without taking into consideration the ultimate program structure, functional testing is resorted to. Hence, it ascertains that the developed software can suffice for all the end user requirements. All user actions are noted adequately in functional testing to ensure that all implementation channels are functioning appropriately in the desired manner and that the desired results are obtained from the input dose to the system.
Let's have a look at the different types of functional testing for ensuring a superior-quality product release. To make sure that all codes are properly implemented, unit testing is conducted. As codes are developed by programmers in isolation, if there occurs absence of any of the following--efficient developers, full code analysis--there crops up a probability of errors making their way into the code, which must be detected in the early stages of software development life cycle and addressed effectively to avoid any intricacies. This would ensure reliability in the product. This type of unit testing would ensure function coverage, statement coverage and path coverage.
To ensure favorable outcomes from every function, functional testing must be carried out to check function points of all the codes if these are in tandem with the functional requirements specified.
Now to obtain desired outcomes from all the functions put together, it's imperative to carry out system testing end to end as it would cover all the required software units. This would ensure that you get the desired results when different software units are clubbed together.
Next comes regression testing, which helps you make sure that there has not been made any adverse impact on any part of the system due to the changes that you've done. Once that it's done, System Integration Testing must be carried out to check if all the systems have integrated with each other appropriately.
For ensuring absolute customer satisfaction with the system, acceptance testing must be conducted; however, the acceptance tests must be written during the initial stages of SDLC. This kind of testing would check if the end users are able to interact with the system with ease.
Resort to functional testing and promise your end users great quality software!
