Front end Testing Versus Back end Testing

What is front end testing? In simple words, front end testing for a client refers to the checking of anything which are visible on the screen of your device. Front end testing also includes the checking of functionalities for a web application.

To do this type of testing, one must be well-equipped with enough understanding and knowledge of business requirements. This is because frontend testing covers different strategies in testing.

Back end testing, on the other hand, involves the checking of applications and database. Data in the front end will go through checking in the back end database.


Frontend testing is always done on the graphical user interface (GUI).  Testing is performed using graphical user interface.

The usage of automation framework tools and knowledge in business requirements are essential things a tester must have in front end testing.

Front end testing does not need any information stored in a database. It essential to monitor and check the functionality of the application.

There are several types of testing used in front end testing. Among them are: Accessibility Testing, Unit Tests, Regression Testing, Acceptance Testing, and a lot more.


As mentioned above, back end testing involves checking of database and applications. In back end testing, proper knowledge in the database and Structured Query Language (SQL) concepts is what a tester needs.

Unlike front end testing, back end testing needs to store information in the database. It does not use graphical user interface when performing the test, though.

Back end testing is needed to detect deadlocks, data loss and corruption and a lot more. In back end testing, it uses the types of database testing are Structure Query Language (SQL) Testing,   Application Programming Interface (API) Testing, etcetera.


Front end Testing Tools:                                                                     

  1. Grunt – used for task automation. This is a JavaScript task runner. A task runner can do most of the hard and complicated work for you and your team with literally no effort at all. To automate just about anything with less effort, they use Grunt.
  2. LiveReload – a Web protocol. It monitors changes in the file system.
  3. Karma – JavaScript test runner tool.

Back end Testing Tools:

  1. Data Factory – data generator and data manager for database testing.
  2. Data Generator – supports performance testing and Load Usability on the database
  3. TurboData – supports relational databases and multiple sequential files


Undeniably, back end testing is the most important among the two. Since it involves the testing, checking and monitoring of applications and database.

Back end testing sees to it that the user can enjoy the expected functions and uses of applications on their devices.

Back end testing is responsible for making the system function properly and secure it from possible software bugs. These bugs may interfere and affect functions of certain applications. Also, this is what makes back end testing more important, as it deals with the overall functionality of an application or database.


Front end and back end testing must work hand-in-hand. They are not there to compete with each other. As explained above, front end testing is done on the side of the user. Back end testing, on the other hand, is on the side of the server.

Each has important roles to play to ensure that a device or an application function properly. It also takes both the front end and the back end testing for a device or an application to function properly.

Back end testing may be more important than front end testing. Hence, needs the feedback of the users to be able to know what to modify or develop in a software application.
