The term “quality assurance” is often used interchangeably to refer to ways of ensuring the quality of service or product. Software Service Testing (QA): is one of the most important stages of program creating. If we don’t pay attention properly, we will not reach high quality.
Each big company has a highly qualified QA engineer. Each one of them can work on one test or on a group of tests which allows achieve excellent results. It is important to mention that nowadays there is no concrete type of test to use which will assure highly qualified product. In order to get a qualification we should use various types of testing including the usability testing. We should use manual and automated testing. With the combination of these two testing we will get more bugs. Quality Assurance comprises administrative and procedural activities implemented in a quality system so that requirements and goals for a product, service or activity will be fulfilled. It is the systematic measurement, comparison with a standard, monitoring of processes and an associated feedback loop that confers error prevention. No matter what methods the quality will be tested by, the QA engineer should study and analyze these factors: functionality, productiveness, report, security, mobility and future service.
Now let’s study the types of testing:
Functional Testing – it is the testing to ensure that the specified functionality required in the system requirements works. It falls under the class of black box testing.
System Testing – it is the testing to evaluate how system behaves under unfavorable conditions. It is the checking of all scheme.
Performance testing – it the process of determining the speed of effectiveness of computer, program or device. It falls under the class of black box testing.
Regression Testing – it is the testing after modification of a system, or a group of related units to ensure that the modification is working correctly.
Unit Testing – it is the testing of individual unit or group of related units. It falls under the class of white box testing.
As most people in the software field know, there are distinct differences between manual and testing and automated testing. Manual testing requires time and effort to ensure the software code does everything it’s supposed to do. Automated testing differs from manual testing where a human being is responsible for single-handedly testing the functionality of the software in the way a user would. Automated testing is well-suited for large projects, projects that require testing the same areas again and again, and projects that have already been through an initial manual testing process. The most popular test type is GUI automated testing, it provides the graphic interface and it has two advantages: it checks as a human being and do not need source code.
Testing is an integral part of any successful project. The type of testing depends on various factors including project requirements, timeline, budget, etc.
