A web-based application is three-tier architecture application. The first layer is the presentation layer known as Front-end, and the third layer is the database layer known as backend.
Frontend Testing
It is a type of software testing used to evaluate the presentation layer of a three-tier architecture in a web application.
In a web application, frontend testing will include the analysis of multiple components such as:
- Menus
- Graphs
- Forms
- Reports and related JavaScript.
Backend Testing
Another part of software testing is backend testing, which is used to test the application and Database layer of a 3-Tier Architecture in a web application.
Essentially, in order to perform the back-end testing, we do not require any GUI (Graphical User Interface) as it is achieved on the AUI (Application User Interface) and database.
Difference between Frontend Testing and Backend Testing
Front end testing Backend testing
| 1. | It is executed on the presentation layer of the 3-tier architecture. | It is performed on the Application and Database layer of the 3-tier architecture. |
| 2. | It is always performed on the Graphical user interface (GUI). | It is always implemented on the Application User Interface (AUI). |
| 3. | While performing the frontend testing, we do not require to store any information in a database. | While performing the backend testing, we need to store the data in the database. |
| 4. | The understanding of requirements is necessary in order to execute the frontend testing. | The understanding of the database is essential to execute the backend testing. |
| 5. | It will analyze the overall capabilities of the application. | It will analyze the deadlock, data corruption, or data loss. |
| 6. | In GUI-based frontend testing, the resources are centrally achieved in cloud computing. | In AUI based backend testing, the resources are executed on a collaboration pattern in Grid Computing. |
| 7. | Knowledge about the automation frameworks tools like QTP, Selenium is mandatory to perform the Frontend testing. | Knowledge about SQL (Structured Query Language) language concepts is compulsory to implement the backend testing. |
| 8. | Frontend testing includes the verification of the application and checks the performance of application whether it is working according to the requirement. | Backend testing execution makes sure that the data is continuing as there is no performance hit. |
| 9. | System testing and Acceptance Testing, unit testing, accessibility testing, and regression testing are performed under frontend testing. | The database testing (API testing and SQL testing) are performed under backend testing. |
| 10. | Just like other types of testing frontend testing also contains some tools, which are as follows:LiveReloadKarmaGrunt | To execute the backend testing, we have some tools available in the market, which are as follows:DTM Data GeneratorTurboDataData Factory |
