Frontend Testing is a software testing in which the front end of the software is tested, whether it is well equipped, well colored, well aligned, well formatted and well designed. Frontend means everything including the interface which is visible, accessible or usable by the users.
Frontend testing deals with everything that the user is able to see in the interface of the software. Frontend testing requirement is different in different software. Some of the software which sorely deserves the frontend testing are the application softwares, web applications, etc.
There are different interfaces even which are different from software to software. For example, some software may contain seven segments LED display or some may be using LED HD Display.
Therefore, when we talk about frontend, it should be mentioned clearly, that what is the type of interface the software is using.
There are different attributes which matters while performing the frontend testing of the software. They are like the CSS which is creating styles for the webpage, the JS which are making the interface reliable, or the coding which is making the software mobile friendly.
The name itself suggests that it is FRONT END testing and thus the importance of the front end comes in front of our eyes. But one may still seek some of the important points which makes the front end testing a necessary one. They are:
It's always seen almost in all kinds of softwares that the coding required to make the interface is larger compared to the codes which are used for programming the backend.
More the code, more the error rate. Also, when a massive block of code runs in an interface, then to make the coding output interface better, reliable, simple and attractive becomes much more complicated.
Therefore, frontend testing is carried out to check whether the codes are developed in such a way that they possess all the properties to make the software interface reliable and attractive. Also, since the front end is one of the most challenging parts of the software, therefore testing is necessary to detect errors.
A particular software front end is designed for different kind of devices. Starting from the bigger screen of computers to the mini mobile screens to the car displays. A software's interface may be visible and usable to different devices.
Therefore, while creating the front end design, all sorts of testing have to be performed to make sure that not only in PCs but the front end is usable and reliable in different devices with different installations of the same software.
These three are the parameters which are almost similar to one another. The core idea is to design the front end in such a way, that the software becomes customizable for different age, culture, places, etc.
To design the software in such a way, the frontend has to be designed and tested to check whether all the requirements are fulfilled or not. Therefore, frontend testing plays an important role is localization, internationalization, and globalization of the software.
Frontend plays a major role in attracting customers. It fully depends in on the interface, that how much the interface is simple and how is the ease of access. A software with a complicated interface may be good in performance, but may not be accepted by customers.
Basically speaking, there are infinite types of errors that may occur in the front. Below we shall discuss few of them:
They are different coding which is used for styling the interface. For example, for styling, the interface of a web application, CSS(Cascading style sheet) may be used. A simple error may occur in the style sheet which may create a huge error in the front end.
Like the color, alignment, size, etc are the attributes which can impact the frontend, therefore the styles must be taken care of while creating the styles.
Now when there are function overlapping or error in syntax, the function may work, but the graphical effects produced by it may play in a weird way, which may irritate the user and may prompt the user for not using the software anymore.
This is the most important factor for a software which has a remote server connected to it. The response time is the sum total of the server load time and the process execution time in the webpage. When the server is local to the software, both these timings are reduced.
But when the server is located somewhere remotely, then the front end has to be designed with utmost care considering all the functions used. Developer with poor skills may design a good interface, but may not be aware of how to optimize codes which may reduce the response time.
The performance is one of the most important factors in the front end design. It is the front end, which decides 60% of the performance of the software. To make the sofware perform better, the functions and scripting along with front end modules are to be integrated accurately.
Front-end optimization means optimizing the code in the frontend so that the performance of the code in the front-end increases. Optimization is mainly carried out in the server side, but with the advent of new generation technologies, many of the processes are executed in the front end itself.
Front-end Optimization advantages :
Since it is an independent framework, that is, it does not depend on any other testing frameworks. This tool is inspired by some other unit testing frameworks such as the JSSpec, ScrewUnit, JSpec, and RSpec. There are lots of extendability like jasmine-DOM, Jasmine-query, and jasmine-react.
This testing tool is an all-rounder testing tool and different types of operations such as assertions, expectations, should, etc which may be needed in different scenarios for different requirements.
This is easy to set up and is highly extensible and can carry out sync testing easily.
There are other tools like the Tape, Karma, and wrapping up which may be useful in testing JS code in any kind of software.
It is a front end testing tool and is used to perform, end to end testing. This tools can be used in different platforms such as Mac, Windows, Linux, and other operating systems as well. It provides us a platform to write test cases in multiple programming languages.
Here test cases can be written in PHP, Java, PHP C#, etc. It offers a way to write test cases without learning the Selenium IDE.
It is an automation platform for functional testing. It also helps to monitor the testing of different web applications. This tool is equipped with AI and the newest technology, such as unique visual modeling, which results in faster testing.
This is a testing tool from
But its highly recommended when, during the test, all the softwares are installed in windows operating system.
There are some other functional testing tools such as as-MicroFocus, Soap UI, Sahi, etc.
This is a front-end testing tool for testing
This process directly outputs the deficiency in the interface after the comparison.
