We implement a short cycle of tests aimed at a thorough analysis of the most critical aspects of software performance: this helps to understand whether it is possible to characterize the created software or its new version as the most stable and suitable for subsequent testing.
In this type of testing, our experts test individual modules or software components to ensure that each piece of software code works as expected. With its help, we can check the performance of different parts of the code at the stage of software development.
As opposed to unit testing, here we combine software modules and test them as a group. This helps to identify problems in the interaction of different modules and check the correctness of data exchange between them: errors often occur because modules are developed by different specialists.
Our experts conduct system tests to verify the behavior of the integrated system, assess its compliance with the original requirements and identify defects. This testing is possible after unit and integration testing has been successfully completed and the correct operation of all modules has been confirmed.
We implement this type of testing in already tested areas of software to ensure that all functions are correct and to identify regression errors: they can appear when fixing other errors, merging code, migrating to another operating system, database or server, or adding a new program section to an existing build.
Our QA functional testing team has extensive experience in creating acceptance tests. Also known as beta testing, UAT is conducted by the end user of the product to investigate its functionality, determine its performance in real-life situations, and check for failures that prevent the main functions from being performed.
Functional testing is a quality assurance process based on test cases of the specifications of the software under test. Functional testing is performed to assess the conformity of the system to the specified functional requirements.
This type of testing can be implemented for a wide variety of solutions: you can implement web functional testing for your web application or site, as well as provide reliable verification of the functionality of your mobile application using mobile app functional testing.
The functional testing process includes a series of tests: unit, integration, system, regression and acceptance. Tests are performed for each software function to determine its behavior using a combination of inputs that simulate normal operating conditions as well as intentional errors or anomalies.
The goal of functional testing of software is to ensure that the software operates according to specifications and meets the expectations of end users. The apparent simplicity of the task should not detract from its real scale and multilevel approach. Different types of functional testing solutions are used in accordance with the specifics of the tested software and in different cases may have different priorities.
The most common types of functional testing are:
