Functional testing lets us analyze a separate part of the application within the context of the entire application. This testing ensures that the system does what users are expecting it to do.
In other words, we test the business logic of a product to make sure all the functional objectives are met and the app or website performs the functionality it is supposed to.
Non-functional
In contrast to the functional testing, non-functional is rather focused on the way app or website operate than compliance with specific functional requirements. It includes user interface, performance, and usability testing.
This type of testing is performed to check the following: how well the product that is being implemented complies with design requirements, level of its usability compared to competitors, and how many users can interact with the product simultaneously.
Unit & Integration
Unit testing is typically applied for small units of code representing individual functions. The main task of this testing type is to make sure that those code units are fit for use.
Integration testing is intended to identify how various components of the software interact with each other. For instance, it can show whether the payment system was integrated correctly into the product or not.
Usability testing
It aims to compare the usability of the proposed design with designs of other similar apps or websites.Correspondingly, the main task of this testing is to find out weak sides in the product’s usability.
To perform usability testing, our QA engineers compare the product’s usability with the biggest competitors in a niche this app or website belongs to.
Load & Performance
Load testing is executed to find out how many users can interact with the system simultaneously. In other words, it identifies the maximum number of users the app or website can handle.
Performance testing includes various tests that are intended to check how the product behaves and performs. Those tests are written to examine stability, reliability, speed, and many other parameters.
Software testing process
The software testing is divided into several stages to build an efficient testing workflow and comply with high quality standards
QA engineers analyze project requirements to eliminate any logic-related issues and identify inaccuracies. Such a revision helps us prevent our clients from spending extra money on making changes to requirements during the development phase. Next, the functionality that will be implemented during the following sprint is picked by the entire development team.
This stage involves defining the software testing objectives and drawing up a test specification. In simple terms, QA engineers plan out what they should test and how they should test it. Also, they determine criteria according to which a software is considered to be ready for the next development phase or sprint.
QA engineers get to work and start testing the functionality that was implemented during each sprint. The main task of this stage is to find bugs, create bug reports for developers, and revise the code once more time after the fixes are made. In other words, QA engineers make sure that all the project requirements are adequately met.
Regression testing stands for an in-depth examination and is performed to ensure that new changes do not break anything in old functionality. What concerns load testing, it is intended to find out how the software performs under normal conditions. Talking about smoke testing, it is performed to check the workability of the product’s most vital functions.
