Front End Testing:
Front End Testing is a type of testing that tests the presentation layer of a 3 tier architecture in a web application. Basically, front-end testing is performed on the user interface (UI) which is also known as the presentation layer in 3-tier architecture.
Back End Testing:
Back-end testing is a type of testing that tests the application layer and database layer of a 3 tier architecture in a web application. Basically back end testing is performed on the application user interface (AUI) and database.
Difference between Frontend Testing and Backend Testing:
| S. No. | Front End Testing | Back End Testing |
|---|---|---|
| 1. | Front-end testing is performed on the User Interface (UI). | Back-end testing is performed on the database and Application User Interface (AUI). |
| 2. | In front end testing, GUI is required. | In back end testing, GUI is not required. |
| 3. | Knowledge about requirements is required. | Knowledge about the database is required. |
| 4. | The front end checks the overall functionality of the application. | Back end testing checks for deadlock, data corruption or data loss. |
| 5. | Any information is not stored in the database. | Information is stored in the database. |
| 6. | Knowledge about the automation frameworks tools is required. | Knowledge about Structured Query Language (SQL) concepts is required. |
| 7. | Application verification is there in front-end testing and then performance is examined to see if it meets the requirements. | The execution of backend testing ensures that the data is moving in continuity without suffering a performance hit. |
