The Significance and Benefits of Backend Testing

Overview: With complex databases and large amounts of data, back-end testing becomes an important step towards high-quality software. While companies make a lot of effort to ensure that everything works smoothly from the user's perspective, they often forget that backend testing is just as important.

Importance: It can reveal performance issues which otherwise will not go unnoticed until your app is released. It will improve the quality of your data, and will further promote application stability to provide full control over the test coverage. On the other hand, testing is related to all the elements that users can not see. This means validating application databases and APIs that represent its business logic.

Understand What Back-end Testing Is: 
Back-end testing is a test that relates to server-side or database. This is also called database testing. Almost recorded data will be stored in back-end as a database. The database can be MySql, Oracle or MS-Access. Back and Testing is Important If this is not done, then it causes the complexity of data loss, data corruption.

A typical web app consists of three layers: front-end, business logic, and a database.

1. Examining the front-end involves validating parts of the application that are visible to end-users (e.g., menus, navigates, etc.). It is also known as a GUI test.

2. On the other hand, back-end testing is related to all the elements that the user can not see. This means validating application databases and APIs that represent its business logic.

3. Database testing mainly includes verification of:  

a. Schema
b. Database tables
c. Columns
d. Keys and Indexes
e. Stored procedures
f. Triggers
g. Database server validations
h. Validating data duplication

What you test in Back-end Testing:

1. In the test database and API development quickly and discover the many bugs when the cost of fixing them is at its lowest.
2. Have full control over the test coverage and therefore test your application more thoroughly.
3. Avoid problems like standoff and data loss.
4. Improve functional stability and robustness of the system.
5. Reveals the quality of data and issues of performance, which do not pay attention to production in the long run.

Advantages for back end testing : 

1. Backend testing is not like Black Box Testing
2. Full attention on test coverage and depth
3. In the initial development phase, many bugs can be found effectively, to perform backend testing, the examiner is expected to have strong background and structured query language knowledge in the database server.
