Backend Testing Tutorial: What is, Tools & Examples
- Details
What is Backend Testing?
Backend Testing is a testing method that checks the server side or database of web applications or a software. The purpose of backend testing is to test the application layer or database layer to ensure that the web application or software is free from database defects like deadlock, data corruption or data loss.
Backend testing is also known as Database Testing. The data entered in the front end will be stored in the back-end database. The database may be SQL Server, MySQL, Oracle, DB2, etc. The data will be organized in the tables as records and it is used to support the content of the page.
Database or backend testing is important because if it is not done properly, it may cause some serious complications like deadlock, data corruption, data loss, etc.
How to do Backend Testing
Database testing mainly includes validating
- Schema
- Database tables
- Columns
- Keys and Indexes
- Stored procedures
- Triggers
- Database server validations
- Validating data duplication
In back end testing, you are not required to use the GUI; you can directly pass the request through some browser with the parameters required for the function and get a response in some default format. Example, XML or JSON. You also need to connect to the database directly and verify the data using SQL queries. Through log files, debugging can be done.
There are various phases in back-end testing. The first step is to acquire design specification for a database server. The next step is to test specification design, followed by implementing the tests in this design with SQL code.
Types of database testing
The types of database testing includes
- Structural Testing
- Functional Testing
- Non-Functional Testing
Tools used for database testing
Some of the useful tools used for database testing includes
Advantages for back end testing
- Back end testing is not like a Black Box Testing
- Full control of Test coverage and depth
- In early development stage, many bugs can be effectively found
In order to do the back end testing, tester is expected to have strong background in database server and knowledge of structured query language.
