Several testing tools have been developed in the bid to enhance software quality and reduce software development time. In the past testing was done manually using simple CLI (Command Line Interpreters) based tools. These tools were close in usage to programming tools with command line interface but they were not suitable for layman. Also, with the advent of complex GUI based programming applications these tools become less relevant and GUI based testing tools were introduced. GUI Testing involves testing the user interface of an application such as controls, menus, buttons, links, and any other control with which a user interacts.
Following are some of the advantages of GUI Testing tools:
1. Fast Testing. The pace of testing can be significantly improved using GUI Testing tools. CLI testing involves hundreds of lines of scripting which is a very laborious and time consuming task. GUI based tools help user to test applications interface by simply clicking the mouse button reducing the time to test an applications interface.
2. Reliability. GUI based testing tools increase the reliability of the output by automating back-end testing functions. Users don’t have to write test script and huge lines of code hence they don’t have to care about the program that’s being run in the back-end during testing. This automated testing aspect of GUI based testing makes these tools more reliable and robust for the users with less chance or erroneous output.
3. Easy to use. Normally, testing tools are quite complex and it requires lots of practice and expertise in order to master their use. Companies have to train their employees to use these testing tools which are time, money and resource consuming. On the flip side, GUI based testing tools are very easy and user friendly. No special trainings or copious instruction manuals are required in order to master these tools. A person with basic testing knowledge can employ these tools in their testing.
4. Integrated Testing. Using GUI Testing tools, user can work on several test cases at the same time and can integrate these test cases into one another. Also these testing tools can be integrated into IDEs in order to perform on site testing. Integrated test cases in a CLI based environment is a very cumbersome task and requires lot of scripting.
5. Regression Testing. GUI Based tools are particularly helpful in uncovering the regression errors which have been introduced by a fix in the code. As GUI based testing tools test the interface, it becomes easier for a tester to see the actual execution of code after an error has been fixed, which helps in regression testing of the system.
6. Web Interface Testing. Website testing is often considered one of the most difficult testing endeavors. GUI of a website is the back bone of any website. Look and feel of a site plays vital role in its success or failure. GUI based testing tools play a very vital role in testing of such applications. These tools enable you to test working of each and every control on a webpage within a mouse click. Testing a webpage and working of controls on it via a CLI tool is a very hefty, virtually impossible task. Hence, GUI testing tools have now taken the place of CLI tools particularly in web based testing environments.
7. Programmability and Scripting. There are scenarios where you need scripting and programming in order to test certain GUI based controls. CLI based tools are usually considered more suitable for such type of testing. However, now there are several GUI based testing tools available in market who have integrated scripting and programming capability as well. It means you don’t have to buy a separate scripting tool for testing. You can simply switch between GUI mode and scripting mode whenever needed and you can write all sorts of scripts required to perform testing.
8. Automation. Some tests cases take long time to execute. For instance a tester might want to test the behavior of an application after four or five hours of its execution or one or two days. For such type of testing, tester will have to sit in front of the PC and check when the code crashes or when application becomes irresponsible. In such situations, the concept of automation can be handy. Several GUI based testing tools now have the ability of automation. Tester can now set the automation parameter and the tool will automatically start executing the test cases. It can be handy when you want to perform testing for longer period of time as you don’t have to sit in testing environment during the whole testing process which may take days.
9. Readable Results. GUI based testing tools produce detailed and readable outputs of the test executed by the testers. The reports contain statistical output of the result using differential graphical objects. It makes it easier for a tester to analyze the output of a test and critically evaluate the reasons behind the failure of a test case if any.
10. Interface Comparisons. GUI Testing tools have now introduced capabilities to compare two interfaces with each other. Using this technique tester can find the similarities and difference between two or more than two interfaces. Differences can be location of controls, number of controls and their functionality.
Several GUI based testing tools are available in the market which has all or some of the major functions described above. These tools can be employed for GUI based testing. RoutineBot is one of those tools. This tool can not only reduce the testing time, but also improve the quality of your software product. The detail of RoutineBot tool can be found at (www.routinebot.com).
I wish you best of luck in your software development and testing endeavors. Happy development and testing!
