GUI testing is an essential part of web development. The main purpose of GUI testing is to verify the performance of the website. Several user interactions such as mouse and keyboard events, graphical elements such as icons, menu bars etc. are tested by the testing team. The success of any application depends on user interactive of the GUI. Bugs in the application can lead to problems where the user cannot perform the desired actions to access the salient features of the application. GUI testing has become an integral part in the web development process. Performance testing tools measure the responsiveness of a system, the stability and its quality attributes. There are several rounds are retesting and regulations during this process. Tasks are repeated multiple times to check the effectiveness of data input (which varies each time during testing), accuracy levels, handling hardware events such as keyboard and mouse, evaluating field components, tool bars, menu bars, controls, images etc. The operation of the application is checked to see how it might react to actual user input. Every web design and software development company resorts to the essential testing step. There are two types of GUI testing – using automated web testing tools and manual testing. An organization can choose the usage of tools and manual services depending on their flexibility and levels of reliability that they wish to accomplish.
Automated GUI testing tools are popular and make use of distinct tools to execute testing. Automated testing tools are chosen on the basis of criterion such as customizability, extensibility, logging and debugging capabilities, supporting unattended test runs and data driven capabilities. The idea is to conduct regression tests that will set up product installation, defect logging and facilitate GUI interaction.
Manual testing will require testers to use manual methodologies to run tests. Real time scenario and real user issues are assessed without exorbitant up-front amounts. Manual testing initiates setting up test cases, which can be incorporated into the automated tool to test the scenarios. It generates avenues to innovate creative testing methodologies to optimize user experience. In all practicality, manual testing reaps greater results through unconventional techniques that amplify user experience. Manual testing uses the Black Box testing methodologies. Black box testing is non-technical, verifies contradictions in the actual system and test cases are designed as soon as the functional specifications are completed. Black box testing uses web Functional/Regression testing Tools to check for functionality, integration, operating system and user acceptance.
Functionality – ensures that the specified functional requirements of the system are met.
Integration – a group of components are combined together to produce a desired output; also the interaction between the hardware and software is tested to see if both of them have the appropriate relationship
Operating system – to ensure that putting the software in a different environment will test adaptability and implementation into that environment.
Acceptance – this phase is usually achieved in conjunction with the customer to ensure that the delivered output/product meets customer expectations.
Retesting – when the issue is fixed by the development team and tester checks whether the problem has been fixed.
Regression testing – re-execution of same test cases to ensure changes such as addition, deletion and any modifications/fixes do not affect the features/modules.
Manual testing is used for single modules as well as multiple modules.
Manual testing process: The practical coordination between development and testing within the manual testing process makes it one of the most preferred testing methodologies for all testers. It involves fruitful interaction between design, development, testing and finally customer.
Several automated GUI performance testing tools have been developed over time that are purchased by companies due to their popularity but may not completely help them automate their testing. Tempted by
new arrivals, the tester chooses the latest automated web testing tools for their testing purposes. Automated performance testing tools gradually tend to downtrend in quality. The systematic degeneration of the automated tool would make any company think twice before investing in an expensive and fragile tool for GUI testing. The flexibility of manual testing makes it the most practical testing technique for all companies. This blog is developed with the help of the testing team in Rarefly. We would like to thank them for their time in reviewing and giving their valuable inputs for the article.
