In layman’s term, you are checking the GUI – anything that is visible on screen, client -side. For a web application, front-end testing would involve checking functionalities like forms, graphs, menus, reports, etc. as well as associated Javascript. Frontend testing is a term that covers a variety of testing strategies. A tester needs a good understanding of business requirements to perform this type of testing.

What is Back-end Testing?

Backend testing is a type of testing that checks the Application and Database layer of a 3 Tier Architecture. In a complex software application like ERP, back-end testing would entail checking the business logic in the Application Layer. For simpler applications, backend testing checks the server-side or Database. It means that data entered in the front end will be checked in the back-end database. The database format can be SQL Server, MySQL, Oracle, DB2, etc. The data will be organized in the tables as a record. Databases are checked for ACID properties, CRUD operations, their Schema, Business rule conformance. Databases is also checked for Security and Performance. In back-end testing, there is no need to use the GUI. You can directly pass the data using a browser with the parameters required for the function to get the response in some default format. For Example, XML or JSON. You also connect to the database directly and verify the data using SQL queries.
