Technitab Solutions reviews in various sorts of power projects prove our competency in this field. 

What is user acceptance test? This is one of the final phases of the software development life cycle. Acceptance tests are carried out after the product is thoroughly checked. The system seems to work fine, but you have to make sure that customers really can navigate it. That is why user acceptance testing is performed by end-users, not by professional testers. Users are given a few tasks to complete. The process is observed by a moderator and then the results are collected and analyzed. Some people tend to underestimate UAT and skip it, thus we should clarify why we need acceptance testing. This technique allows developers to see how usable the system is, what difficulties customers face, and what they like most about the software. Such information helps fix bugs and improve the product before it goes live. UAT is intended to get approval for release in case the system operates properly. Read the full article

"User acceptance testing, or, as it is also known, end-user testing is one of the key phases of the development and testing life cycle. This functionality testing technique is applied during the final stages of the development before the system is released. The main purpose of the UAT is to get the client's approval of the created application. As any system is created for customers, their estimation is highly important. In the process of executing acceptance tests, real-world scenarios are simulated in order to confirm that the system meets the testing criteria and therefore can be released to the market. Checking such features as functionality, usability, performance, and UI may be involved as well. Take into consideration, that even though the user acceptance test is carried out right before the production, it is important to have enough time for fixing the detected bugs. This ensures delivering a high-quality and satisfactory application. UAT is categorized into several types, including alpha and beta testing, contract, regulation, and operational acceptance testing. The choice of the method depends on your circumstances and goals." Read the full article

Some people wonder why we do acceptance testing. This technique is underestimated by somebody and considered a waste of time. However, the acceptance test is a vital part of any software development life cycle. This stage should not be skipped if your goal is to make a competitive, high-quality product. It is also necessary to clarify who performs acceptance testing. Such checking is done by customers in order to check how the system can handle the tasks, it was initially designed for. The system may be created quite well, but if customers can not use it easily, such a system will not be successful. Thus, every owner wants to make sure the website meets all users' requirements. Let's outline the key stages in the process of carrying out user acceptance testing. Consider the following 5 phases: thorough preparation, coverage, running the test, reporting, and reuse. Sticking to this checklist ensures receiving the most accurate results. Read the full article

What is factory acceptance testing and is it important? In comparison with other types of testing, FAT is not obligatory but rather recommended to be done. These tests are similar to site acceptance tests, but they are conducted not only by the client; the client representative is involved as well. Also, unlike SAT, a FAT takes place before shipment and installation. The primary objective of the factory acceptance test is to verify whether the system operates properly and conforms with its intended specifications. Simply put, FAT is conducted to make sure that the system under test performs all functions, which are supposed to be performed. In case non-conformities are detected, it is highly important to handle them as soon as possible. All the abnormalities that are found out must be documented in a report and fixed before the installation. Due to the name of this type of acceptance testing, it is obvious that the test is carried out directly at the factory. Read the full article
